well if I only have to put the OS with the apps I barely use 35GB, my idea was to have also the data on the SSD for a faster access and use..

I still have to make up my mind...

opening the application is what takes the time not the data.

eg. opening itunes takes long once itunes is open playing a track is instantaneous.

You do the same on a pc os + applications on SSD and all data / saves on a HDD.
 
@ Nuke16 thanks for the impressive explanation, I was wondering if that was the case of his particular caddy but is not the case. Which SSD will have it's own garabage collection ruotine as tunderbolt caddys have an insane cost and I would rather put to good use a USB3 door...

My Vertex 3's MAX IOPS in Raid 0 have Garbage Collection
 
You move your home directory appart from applications onto the internal HDD and then create alias links to those.


Could you please tell me how to do this? My lacie thunderbolt ssd is arriving tomorrow and I'd like to know how to get everything set-up.

Thanks so much.

open your home directors. Hold command and click go at the top open home.

Open your external drive and create a users folder.

Drag downloads, documents, pic, music, (basically everything but apps i did) over to teh new drive.

Then hold options and command and drag apps. (this will create the alias folder).

Once you have done that go to users and groups.

Right click on your name advanced settings.

Change your home directory to your external drive.

Restart and its all done.

So in other words you mean that the benefit of having all the datas on SSD is so marginal that it would be a waste?

Thanks passey. I have a few questions for you, as I'm a little confused.
You say to open home directory. Are you talking about on the ssd after I have moved my info onto it? I plan on using CCC to do that.

Then you say to open the external drive and create users folder and drag everything except apps over. Are you talking about the ssd or the internal hdd? That's where I'm confused by you saying the external drive. The ssd will be my external drive which I thought should only have apps on it.

Sorry if I may be misunderstanding what you're saying, but could you please clarify it for me?

Thanks so much. I appreciate the help.

yeh by external drive i meant not the OS drive sorry.

use CCC and once its complete hold options when you boot and select the SSD.

Then I erased my Mac HD.

Open home directory on the SSD and Copy everything but applications to the HDD. Make an alias of applications on the HDD.
Delete all the old directories apart from applications off the SSD once you have changed your home file location in users & groups.
 
Thanks again passey, I'm no longer confused. So if I do this will iTunes automatically see where my music and movies are and open them or will I need to do something else to direct it to them?

This is probably a stupid question, but why do I need to put aliases for my apps on the hdd? I must not understand the way aliases work because I thought that aliases of the data, ie music, movies, would need to be put on the ssd. As you can probably tell, I don't know very much about these types of things.

Because your not just moving the folder but also going into system preferences and move where the home directory is itunes will be fine and auto pick up music.

The HDD is going to have actual files for download music pics etc but not apps because you still want them to run off the SSD to get the speed benefit.

The alias folder is a ghost folder that will just point to your SSD location as we want applications to run at full speed.

You could do it the other way and make aliases on your SSD for docs, music etc. Both will do exactly the same thing.
 
Thanks so much. You've been a great help. SSD should be here within the hour. I'll post back if I have any more questions.
 
Bus powered SSD

I don't think it's a size issue, but a power issue. Given that the 512GB 840 Pro uses the same amount of power as the 256GB 830, and the Samsung 830 has been sucessfully used in bus powered external enclosures... the 512GB Pro should work too. But as you said, it could be a relatively expensive failed experiment. I only have ~200GB on my entire Fusion drive, so 256GB drives work perfectly for me, but I'd still like to know if a 512GB Pro actually works in a bus powered TB enclosure.

Maybe things have changed since this was posed but I have put an 840 EVO 1TB SSD into a Lacie thunderbolt rugged bus powered enclose and it work absolutely fine. (swapped out the HDD).

What isn't clear to me yet is the whole TRIM thing. I assume it's an OS thing and not an internal thing to the drive. So I can use TRIM enabler to get my OS to send the commands.. Whether the 840 EVO can receive that command over TB or whether it even needs it remains mirky to me.. Any help appreciated.

Yes... and TRIM will work over an external drive attached with TB, bit not USB.
 
I'm using a Samsung 840 in a USB 3 case velcro attached to the back of the imac stand. Can't remember the exact speeds but I think it's around 500 of top of my head.

I know you were asking about thunderbolt but just thought I'd share my setup anyway. Not been running long enough to report on how the lack of trim affects it.

Plenty fast at the minute though, my USB 2 external drive are my bottleneck now :)

Thanks, it looks like larger SSDs now use a lot less power than they used to.
