2011/2012 Macbook Pro Dual Drive (SSD+HDD/SSD+SSD) Setup Suggestions

Two questions:

I ordered the Fenvi branded bay (cost less than $15 shipped to Norway!),
do you know if S.M.A.R.T. will work? My guess is that its completely dependent on the HDD/SSD, but I dont know.

I have a late 2011 MacBook Pro 13", should I put my SSD in the optical bay? I feel safer that the mechanical HDD is inside those rubber suspensions that is in the regular bay, but its a waste if my SSD (which supports 6GB/s) will only get 3GB/s. Id rather have both :)

EDIT:
Oh got another question more,
How will the Eject button work? Will it do nothing by default? Or will it unmount the drive in the optical bay? If so, what if this drive is the system drive? Thanks

1) Thats great you got the fenvi branded, its what I'm using and happy so far 100%, S.M.A.R.T does work 100% no issues and same with Sudden Motion Sensor.

2) Its up to you but if your SSD is SATAIII you will more than likely have to put it in the main Bay...I had to and my HDD in OptiBay works without issues + Sudden Motion Sensor works 100% so when laptop is shaken the drive is protected! no worries about the extra protection from the Rubber mounts in the main bay...

3) Eject button becomes disabled and has no function....I have set mine to bring up the dashboard as I have disabled "Use Dashbard as a space" that way I can access my widgets form any "Desktop" I am on with press of a button and then press it again to get out of dashboard.....I liked this.....You cannot set it to exit the system drive...I just let my drive sleep(my HDD) when not accessing it within 5min. This can be set by "SpindownHD" just search for it in your spotlight search...
 
Guys, I would like to ask you how to prevent my HDD in the Optibay from waking up a couple of minutes after I ejected it?

For example, I eject it and then it's quiet for a couple of mins --- and I'm only surfing on the internet in the mean time, not doing anything else. However, it wakes up after a couple of mins.

Some additional info:

- only my Downloads folder is on the HDD (and I'm not downloading anything when the HDD wakes up)
- I use iStat Menus but have disabled HDD monitoring
- I've added "HDD" to the Privacy list on Spotlight (but apparently that won't do because as soon as I eject my HDD it will disappear from the Privacy list - so I guess I will needto run the Terminal command to prevent Spotlight from indexing the HDD in the optibay? Is that what you did?

Is there anything else I could do to prevent it from waking up for nothing? By the way, I'm using hdapm - could this be the culprit for its waking up?

Thanks fo good insight. I would like to check what speed my SSD will get in the optical bay before i install it as a system disk :) it is supposed to get 550MB/s read, and 520MB/s write (Vertex III). If it gets Sata3 speeds I'll leave it there. What program to use to check speeds?

Now im just waiting for my fenvi, and hope its not fake or anything haha it was dirt cheap. And if its fake, then i hope its a good fake :p

I'm from Linux, I don't know how to do this on a Mac yet, how do i move the Users folder and the Applications folder to the other disk after I reinstall OS X on the SSD?

Hey, I used black magic from the app store, that shows real world results of what you will actually get....

Also there isn't/can't be anything fake about a enclosure, its just a enclosure....simple as it sounds lol and has a port for connector, it doesn't physically do any work....so fake or real they just as good.

I didn't move my user folder, I don't see the point in doing so, people waste their time and stress about making it work right. Leave it on SSD u'll be happier and be up and running in shorter time frame. Just do weekly Time Machine back-ups. its simple plus this will let you HDD sleep when your not using it, giving you a battery life boost and a MUCH MUCH quiet macbook pro....

Thanks again, just installed Black Magic and checked my tracking number, the bay has come in to the country (yay) But cheep postage is slow in my country :(

Touché about the adapter part of it, because the adapter can be the weakest link, and you can lose a lot of speed in plugs. This is much more evident in network cables and such, but also valid for Sata connectors and such.

And I cant have my Users folder on the SSD, because my SSD is only 60GB and my user folder is ofter be close to 200GB, but varying. As I was saying I come from Linux, where its almost as rule of conduct for user files to be on the "home" folder. And I really enjoy following this as its really practical :)
 
a problem i'm having - after ejecting the drive - is that the hdd in the optical bay will continue to spin once it awakes from sleep. using cocktail to force the hdd to spin down after 3mins doesn't help either. i've never been able to solve this problem or find a solution that works.

I was only facing that problem when I had paragons NTFS for OSX enabled, it has a bug in it....if you have iSTATS or anything else thats monitoring your HDD it will wake it up even if its not mounted....I don't have the issue anymore after I disabled NTFS for OSX driver.

run this sleep command in terminal "sudo pmset -a disksleep 1" (without the quotes) see if it helps....I removed cocktail as it expired on me so I jus ran the command. Also try to set the power management of the HDD as if its set to MAX it will spin on n on n on, first check if its disk1 or disk0 then run "sudo hdapm disk0 195" (without the quotes and put disk1 if its disk 1 or disk0 if its disk0).

If it still doesn't sleep then you may want to launch terminal and use the following command "sudo fs_usage" (without quotes) let it run for a few mins, then check the log to see whats accessing the HDD(check by disk1 or disk0 depending on which is your HDD)

To check where your HDD is launch disk utility then click on individual drives to check their location...

Also all commands starting with "sudo" will request password it is completely normal.....then will show you the result of your command you ran..
 
I just wanted to say, I got my HDD caddy, and installed the SSD in it. It didn't work, so I swapped the SSD and the HDD, and it worked.

Now I have some concerns.

Remove Journaling?
I dont need journaling on the system disk, and I dont need journaling on an SSD at all. Further more it reduces the lifetime of the SSD. I want it gone :(

Making sure TRIM is enabled?
This is enabled by default? How do I make sure it is?

Setting Swappiness to 1?
OSX is horrible with paging, I want it to be sett to only when ****ing necessary.

noatime on the disk?
Not writing when the files were last read will save the SSD a lot of writing.

noop disk scheduler?
noop is a disk scheduler that does not take account of where the data is physically stored on the disk, as this is unnecessary on an SSD. If its turned off you will get faster read speeds for lots of small files. In theory anyway.
 
I read the thread. So am I correct that you recommend copying your whole time machine backup over to the SSD then moving files over to the second HDD?

Sounds great except often people want a small SSD for the OS and apps only. I would do it tomorrow if I didn't have to wipe my current HDD to remove the OS from it.

I had the same problem but I don't use istat or any NTFS driver. I do have Parallels installed which I suppose installs MacFuse.
I (kinda) solved the problem by having Sleepwatcher execute the eject command on the disk when OS X wakes from sleep.
 
Everyone will face small issues with getting their disk to sleep, I don't think I can help everyone but I'm sure if you search on google you will more than likely find your answer. As I recommended another user on another thread, best way to find out what exactly is causing your drive to wake up every now and then is run the following command in terminal without quotes; "Sudo fs_usage" it will ask for password, enter it and let it run for a few mins, then scroll through the log in terminal to determine whats accessing your "disk1" or "disk0"(depending on location as at times it seems to change on its own, which doesn't cause any issues if anyone is getting worried after reading this fact) followed by the partition name.


If you don't want to do anything, but also at the same time don't access your HDD as much then your best lazy way solution is simply unmount the partitions even tho its a little inconvenient for the next time you want to jump into it to get a file.

wish you all luck, let the dual drive setups become universal:) I plan to keep my MBP for another few years to come without selling/upgrading/changing so I won't gain anything even if apple releases a OD-less MBP lol
 
Thanks for your tips, especially around flux and keyboard remapping :) I have been using a SSD+HDD via a caddy for months and can report all is OK.

I formatted both disks with exFAT as I use Windows in VMs regularly for work. OSX and Windows work absolutely fine with exFAT and it negates the need to buy ParagonNTFS for example and allows Windows to see my OSX partitions.
 
Best format for data disk

Very interesting thread.
My MBP 17" is arriving the next week, it will be equipped with 16 GB RAM, a 256-GB SSD (which will be mounted in the main HD bay, following your suggestions here), and the original 750GB-7200RPM disk will be moved in the Optical Bay.
As suggested here, the SSD will be partitioned half for OSX Lion, half for Win7/64. I will install proper drivers on OSX (Paragon) and on Win (Macdrive), so that each OS can see the "other part" of the SSD.
Now, is the question: which is the best format for the 750GB data disk? I would prefer to keep my data on a single volume, without partioning also this drive...
The drivers already installed for allowing reading the system disk's partitions will enable both OSes to read the "other format".
So the choice here should only be based on performance and safety.
Do you think that it will be better to keep the 750GB HD in HFS format, or in NTFS? Or in the new ExFAT format?
Any experience showing that one of the three causes problems or provides some benefit?
I do not have time for experimenting which format works better...

Hey Great! Congrats on your purchase first of all. Also its awesome my threads been helpful to you:) and that you are considering a similar setup.

As for your 750GB HDD, It would depend on what OS you need more storage on.....Because I use OSX 95% of the time I decided to have the whole SSD for OSX but its great you are doing the half/half. For my HDD I did the 350/150(500GB Total) Split, Now that I think of it I didn't really need to set aside 150GB for Windows...Should have done little less maybe 100GB at most....I am currently only using about 50GB on my Windows 7 Partition.....So for the HDD it really comes down to what OS you are going to use the most and how much storage you need for it. IF you are going to get Paragon and Macdrive for Windows then there is no worry about read/write....however you don't honestly even need Paragon.....You are more than ok with just macdrive if you keep OSX as your main OS...after all you are getting a Macbook Pro so it should be your primary OS of day to day use.


Here is a setup I suggest you do:

Install OSX Lion + Windows 7 64Bit on your SSD (Before you remove the Optical Drive...as its required for Installation of Bootcamp Drivers+Win7
Format HDD to NTFS
Install Macdrive on Windows 7
Also get Parallels or VMware Fusion(can be found for free in plenty of places:p)

Then you can run Windows 7 in Virtual Machine(It will just load up your bootcamp setup without having to reinstall Windows 7 automatically which is amazing as it requires no extra work other the installation of the Virtual Machine software it self)....since you are getting Macbook Pro 17 and with 16GB Ram it is going to really powerful and won't slow down unless you do some super heavy work on the Windows 7 Side....Also Try to stick with OSX as your main OS and Win7 for Gaming and any work that you cannot do on OSX.....its for better Battery life, Performance and security....goodluck let me know if you have any other questions, sorry for late reply I haven't been around on the forum much.
 
Following the instructions, my system is now up as follows:
- 256Gb SSD (Corsair Performace pro) in main bay, the original 750Gb HD in the optical bay with a Fenvi adaptor
- two 128 Gbytes partitions on the SSD, half for Lion, half for Win7
- the 750Gb HD is a single large partition, exFAT, so it can be efficiently read and written by both OSs...
- Win7 has read-only access to the OSX partition, instead OSX has read/write access to the NTFS partition thanks to Paragon driver, but I was planning to use mostly OSX, and launch Win7 only when needed
- I also attempted to install Parallels, but OSX was continuously hanging with it, requiring hard reboot and restoration of file system on both partitions
- the problem, however, is that whilst launching Win7 natively everything is stable and fast, launching Lion has severe problems (even without touching the Windows stuff), as programs often stall for minutes, hanging the system completely, and sometimes they never unblock so I am forced to hard reset (and go through that mess of system self-repairing)...

I start fearing that something is wrong with my SSD, albeit it does not report any SMART error, and it passes with zero errors all the diagnostic programs which I managed to get, either on OSX and on Windows...
I am frustrated to see continuously OSX locked, with that innerving rotating wheel, and noting which I can do for unlocking the stalled app and the system (the suggested key combinations for terminating stalled apps also seem not to work).
And, even after an hard reset, Lion has the tendency to re-open all the programs which were running, so that, if one was stalling, it is going to stall again... I must be very quick to press cmd-Q several times after logging in, for killing the re-opened apps before they stall again...
So in practice I am working 99% of the time with Windows booted natively from its partition, where everything is stable and fast...
I am going now to do a complete rebuild of the OSX partition, this time without attempting to install Parallels (which was the first app which began to stall).
If this fails again, I will conclude that purchasing an SSD on Ebay was not a good idea, and I will need to buy another one...
Do you see any other possible cause for these stalls?
I do not think that it can be a memory-related problem, which would cause blue screens on Windows, and the memory I bought is Mac-certified and from a reputable vendor...

As for the stalling or having such issues was one of the reasons also why I decided to leave windows on my HDD as my "Back-up" OS incase my SSD ever died...because my windows can access my HFS+ Partition at all times via Macdrive...and I backup my entire OSX Partition once a month.

I did experience apps stalling my self(Quicktime, TextEdit and few others) But I left them alone and now they all work fine after a few OSX updates....only app that stalls now is Mail.app at launch for about 30seconds and then it continues to work perfectly fine. Sometimes little patient is the key:).

exFAT is good format except it has a limit of 4GB Max per file size.....So I think if you ever transfer a file(s) bigger than 4GB you will have trouble.....for me that was a deal breaker and I went the smarter way, giving each OS its own dedicated type of file system so no issues ever come up and with the help of Paragon and Macdrive the cross connection is completed. To be honest I don't run Paragons driver all the time...I only run it when I need it because otherwise it does not let my HDD Sleep.......(90% of the time my HDD is sleeping when I am using my Macbook Pro.....also another reason why I got a bigger SSD and dedicated it to OSX so that all my day to day file usage can be stored on SSD....)


If you are going to redo OSX Lion, Make sure to format the Partition before you continue to install because otherwise it will not format it and instead just reinstall without doing so as far as I understand and when you go back into it, the problems will remain.....so format first, then fresh install and it should solve the problem. Also I would not recommend buying a SSD from eBay...I hope it was new? also never buy something so delicate from eBay unless seller has lots of feedback....I Paid $250/180GB from a local store...
 
Well, after browsing all the threads here on macrumors, i finally found others with my same problems, erroneously addressing the SSD. In fact, the problem is with the memory upgrade to 16GB, which I did altogether with the SSD installation.
It is Corsair RAM (2x8GB, mod. CMSA16GX3M2A1333C9), which was sold in a nice blister as "MACMEMORY", and declared fully compatible with MacBoookPro...
Instead, memtest reports dozens of errors!
I have just reinstalled my original bank of 4GB RAM, and now memtest does not find any error, and Lion is finally stable and quick...
So I am shipping my RAM back for replacement, sorry to have disturbed you with such a trivial case...

Regarding exFAT, instead, I have to correct you: exFAT does not have any limitation on the file size, nor on the number of files per directory! Till now it revealed to be faster than both NTFS and HFS+, and at least as reliable as them, as the file system survived to a dozen of system crashes and consequent hard resets (due to bad memory banks, as now I know).... the NTFS and HFS+ partitions needed to be repaired almost every time, the exFAT partition never suffered any problem...

I copied successfully on it a number of large files (32-channels audio recordings in W64 format, the longer is 16 Gbytes..).
So I think that it is the optimal choice for a "data disk" where both operating systems can read&write...
 
ya there u go, Ram was the issue, u should get the one from Fry's.com...they have Corsair 16GB for $109.00.....I'll be upgrading my Early 2011 Macbook Pro in the near future from 8GB to 16GB...but for now I don't need it as I am doing perfectly well with just 8GB...

as for exFAT I read somewhere while back there was limit but thats good that it works for both. I am pretty happy and hassle free with my setup, at the en dog the day what matters is what works for YOU:)
 
also the SSD has problems...

Well, after reinstalling the original 4Gb RAM, I did hope to have solved my problems.
But the system continues to exhibit random stalls and sometimes completely hangs...
In the end I concluded that also the SSD is not working, I reinstalled the original mechanical 750GB HD, and everything is back to normality...
I was very unlucky to receive both a set of bad memory sticks and an incompatible SSD.
The same SSD mounted in a Windows machine works flawless, so I do not think that the SSD is "broken", simply it is not compatible with the SATA-3 controller of my Macbook pro 17" 2012 (MBP8.3).
I am shipping everything back to Corsair Support, and see if the replacement works better (for the RAM I suppose yes, for the SSD I fear that this model -Corsair-CSSD-P256GBP-BK-Performance-Series-256GB- cannot be installed on my MBP).
It is a pity, the machine was fantastic when booting form the SSD, now with the original disk it seems to be "braked"...

So the final question: can anyone testify for a brand-model of a 256GB-SSD which surely works inside a 17" 2012 MBP-8.3 laptop?
Thanks...

I would suggest a Intel or Samsung....they are two of the top!

PS my Corsair Force Series 3 has been working fine since October 2011......
PPS the macbook you own isn't a 2012 its a "Late 2011 Model"....mines Early...the 2012 are coming out in a 1-2 months max as they are overdue already for the refresh since Apple has been doing 2/year.....

Yes, it is model 8.3 listed as "late 2011" here: https://support.apple.com/kb/HT1237

I am not sure that a sata-3 Intel SSD can work at all in a MBP 17", as I did read here that Intel drives are among the problematic ones:
http://communities.intel.com/thread/20352?start=0&tstart=0

Regarding the Corsair Force 3 Series, this is definitely a sata-3 SSD: But it will negotiate a sata-3 connection with the motherboard only on models equipped with the latest chipset, which are mounted only since early-2011 models. More precisely, the early-2011 started with sata-3 supported only for the "main bay", while the "optical bay" was still sata-2. Later along the year, Apple started releasing laptops equipped with sata-3 links on both bays. But, due to bad shielding, mounting a sata-3 drive in the optical bay is not working, according to what OWC says...
You did not say if your Corsair Force 3 Series is connected in sata-3 mode or in sata-2. I understand that currently Apple is only selling sata-2 SSD dirves, which do not have problems, albeit being significantly slower. And if you install a sata-3 drive in a Mac which does not support sata-3, it will negotiate sata-2 speed, and work perfectly...
So the question is: are you sure that your Corsair sata-3 drive is actually connected in sata-3 mode? Which model of MBP do you exactly have? And is the SSD connected to the optical bay connector or to the main HD connector?
