The Samsung 840/840 Pro SSD thread

An HDD would definitely suffice, however, I'm still unsure which is the fastest/dependable I could possibly install while avoiding the issue with the SATA. Thanks again!
Impossible, because all modern SSDs use the SATA 6 GBit/s protocol, IIRC. As you know, you need a HDD/SSD with a SATA 3 GBit/s interface. I recommend HDDs like the Western Digital WD10JPVT. Here is a test:

Samsung SSD safe for MBP Mid 2012?
Hello guys,
I read a lot about using a Samsung 840 Series in a MacBook. The opinions were different.
On the one hand the SSD crashed after a few months, on the other hand everything worked perfectly fine.
But I experienced, that mostly "older" MacBooks were affected. I didn't find many reports about using the SSD in a Mid 2012 MBP.
My question: Does anyone of you have any experience or advice about using the 840 Series in a MBP? (I have a 13inch mid 2012 mbp).

I have a 2012 cMBP, 15" with an 830 in it and it's been terrific. I also have the 840 in my iMac and two Dell PC's and it's been solid there too.
The 840 is experienced and proven to be good and reliable. Of course there is always margins for bad ones here and there, but they're quite few from what I see.
My first one died in a matter of weeks. I mean full-on died - completely irrecoverable. Fortunately my iMac is my primary machine...my MBP had nothing of importance on it that wasn't backed up.
Got it replaced, and this one has been great. This one came with the most up-to-date firmware already on it, the other one I had to update myself...can't help thinking it was linked to that.
Anyway, it's been great in my '09 MBP for a while now. Ticking me over until Haswell..
Early 2011 13" i5 2.3 ghz w/samsung 840 pro 500 gb
Hey guys,
First let me list my MB Pro specs:
Early 2011 Macbook Pro 13" 2.3 GHz intel core i5. Everything is stock besides the ram which i have upgraded to 16 gb's.
I bought the samsung 840 pro SSD 500 gb on amazon recently because i heard this was the best SSD in terms of reliability and performance. I read that there is an issue with the 2011 MBP as it only supports 3 gb/s in the optical drive and 6gb/s in the main bay. I want to switch my main HDD with the new samsung SSD and set my HDD where my optical drive is. Are there any issues that i should be aware of about this procedure? Also, if someone can point me to a step-by-step guide on how to back everything up, clone hdd to ssd etc that would be great. Thanks!

Edit: Sorry, I should have read the link in the previous post more closely. I guess there actually is an issue with SATA 3 devices in the optical bays of certain MBP models beyond the speed cap.

Only issue is that you'll need an optibay bracket to keep the HDD in place. You can get them from OWC, maybe elsewhere too. You may have already got that covered though.
Hi all, here is my problem:
i have a 2012 13" MBP 2.5 i5 8gb ram. I replaced original hdd with a 128gb Samsung 840 pro (Firevault 2 encryption). the MBP is running in clamshell mode connected to a 50" LED TV operated by a BT Apple Keyboard and Magic Trackpad.
Lately i have been experiencing the following: activity monitor will show high data read/write and while this is happening my magic mouse will become very choppy/jumpy almost unusable on occasion both the mouse and the BT keyboard would disconnect. I have since done multiple clean installs (the most recent one was today) the drive has never been completely filled up or zeroed out. I do have Trim enabler up and running (it has been since i got the drive).
All hardware/software if fully updated. The only part that isnt running newest software is the SSD's firmware which is DXM04B0Q. The newest one being DXM05B0Q - but according to Samsung this only enables DAS as a default on. So it really shouldn't make much of a difference (from what i understand).
I have eliminated other possible reasons for this problem (BT interference, CPU usage, RAM usage) and am at my whits end as to what i can/should do.
Any advice...?

I would update the firmware nevertheless, Samsung usually don't publish changelog.
Maybe it helps.

Thanks Paul i was thinking about that but i dont have a pc handy and the mac iso that samsung offers does not work (Bios vs EFI) thing
I have a '09 MBP
Last week put in the 840 PRO - 256
Much snappier
Was easy all way around to setup/install
Not wanting a new MBP anymore - this one feels like a new machine

Just figured I'd make a note of this:
Upgrading to OS X 10.8.5 disabled TRIM support for me. I tried to use Chameleon SSD to re-enable it, but it wouldn't turn back on. I did it a second time, but this time I restarted the system myself, after quitting Chameleon. By comparison, the first time I restarted based off of the restart dialogue that Chameleon brought up (which is still the system restart dialogue, but it came up by Chameleon's commands). This worked, and Chameleon then reported that TRIM was enabled.
Samsung 840 500 GB is the drive I'm using in a late 2011 MBP.

Fresh SSD install, what are the necessary steps to take?
I just installed two samsung 840 pro ssd's in my 3,1 (yes I know it's only sata II) but am not sure of all the necessary steps needed. I first formatted those drives to os extended journaled drives, is there a need for me to do a firmware check? since I just bought them would they come with the latest firmware or could they possibly be NOS with older firmware. I went on samsung's site but couldn't find much info on the firmware, all I saw was their software for windows.
Raid question.
I saw as concentrated you get both drive sizes combined as JBOD but you don't get the performance/speed advantage of raid 0. I was under the assumption that raid 0 both drives were combined as well. I have a 256 and a 128 and under striped set in disk utility it only shows 256gb.

You can check the firmware version in System Profiler under the Serial-ATA tab.

With RAID 0 the capacity of the array depends on the smallest disk. I.e. with 128GB and 256GB drives, you get 256GB (2x128GB) and the remaining 128GB in the 256GB drive will be left unused. In other words, RAID 0 only works well with drives that are of equal capacity.
JBOD, on the other hand, works with different capacities as all it does is to combine the drives into a single volume but you lose the speed advantage too.
Damnit! I read that equal capacity drives should be used but I read others stating it's not true that you don't have to. I was debating on getting another 256 but didn't really need 512. Guess I should've read around more
Back to the store I go hahaAlso, is trim still unusable for raid 0?

Firmware Upgrade?
I'm finally getting ready to do this Sunday, but I'll need to reinstall my DVD drive before attempting the upgrade. Can somebody guide me through the firmware upgrade process again using a bootable DVD?
Also, after I've updated the firmware, how can I enable TRIM?

I have the same situation
Hi kasecasiunkilo, could you find something about this issue? is it normal or should I get worried?
