The Samsung 830 SSD thread

Wanted to post a followup to my issue (noted above), in case anyone else runs into the same problem I didn't want to leave you hanging.

I enabled TRIM over the weekend and have not run into the issue again. Running activity monitor, it seems like the problem consistently popped up with Safari suddenly taking up a huge percentage of the processor, so I think this is a Safari issue and nothing to do with the drive or computer itself.

If the problem comes up again, I'm going to just start using Chrome, I guess. Not that there's anything wrong with Chrome, but it's a shame that the native OSX client gives me such problems.


Next up: RAM upgrade.

Out of interest, where do you have your User profile stored? I have the same setup as you (same laptop too) and had a noticeable difference in speed when I moved my profile to the SSD (although I keep the music and movies folders on the HD).
 
I have everything except for my downloads folder on the SSD right now.

That's not saying much, though. I've been holding off on installing anything until I got the issue fixed, certainly wouldn't want to reformat and reinstall all of my software. Ugh.
 
Just installed a 128 GB 830 in my base-level mid-2011 iMac with 12 GB of ram and the standard 500 GB HDD. Also, if it matters on any level, I keep my 1.5 TB iTunes library on a 3 TB WD Green drive connected via Firewire 800. Aside from enabling trim support, repairing permissions, and moving the Home directory to the HDD, is there other standard practice stuff I should do to get the most out of the SSD? I've read countless other suggested tweaks, but many of them seem to be a little more obscure in nature, to the point where I wonder if there's truly much benefit in performance and data reliability considering you're having to do a fair amount of under the hood tweaking of the OS. Any help would be appreciated! Thanks!
 
ugh. Issue is back, and worse.

Still mostly happening with safari (also happened in imovie but I WAS rendering something). Any suggestions?
 
How do you guys enable trim on this drive? I tried Trim Enabler and rebooted the machine but it says it's enabled but maybe my drive doesn't support trim? But in the System Info it says it's off/no.

I read a thread on manually doing it, but it's a bit confusing.

Hmm funny you posted this.

I had enabled Trim on my drive after first getting it and installing it a few weeks ago. It enabled fine, as noted in System Profiler and everything.

Upon reading your post, I decided to give it a check real quick... and it was reporting "No"! Launched Trim Enabler which I still had, and it also indicated that the patch was not enabled!

Very strange. I think maybe the 10.8.1 update changed it back possibly? Cant think of anything else that might have changed since then.

Anyways, re-enabled it with Trim Enabler and it seems to be staying again.

That's exactly what happened, Andy. Every OS update will disable TRIM on non-Apple SSD's.

Something you gotta remember when an OS update is released.

It's just the price - and a small one at that - of using a non-Apple SSD.

Well mine won't enable at all.

You might need to update Trim Enabler .. The terminal commnads to enable TRIm are different in 10.8.1 than 10.8.0 because, well, Apple changed the .kext ... so using the previous commands will not enable TRIM..

Unless I have he wrong link for it but I pulled th latest one from the guys site two days ago.

You're welcome. I'm amazed you can actually tell a performance difference right after installing the new app. May I press you for details?

Basically before I got it on, the laptop took about 5 seconds to shut down, and took about 12 seconds to boot up. This is an estimate. Now with it, it shuts down almost immediately. Within 2 seconds. And boots back up within 5-8 seconds.

So I was getting fed up with my drive, and started to do some research on the Crucial M4. My plan was to return the 830 to Amazon and pick up an M4. I came across this thread:

The beach balling generally only happens if you put the SSD in the optibay, so be sure to put the SSD into your HDD bay.

So I figured, what the hell, might as well give it a shot.

It's only been an hour since I made the switch, but so far no beach balls. Activity monitor is way more active, too. Lots of reading and writing going on (it used to be pretty minimum with an occasional spike which would cause me to hang up).

Fingers crossed. I'll report back in a few days regardless of what happens (or doesn't happen).

Samsung 830 :)

Had the M4 but that's in my gaming rig now.

My SSD is in the Optibay with no issues so far. Only way I could do it for Windows to work. :/

Clyde, thank you. That worked like a champ and my laptop is actually much faster now. :)

Glad that worked .. Apple added some additional tests for 'their' SSD identifier that needed to be patched .. There was a surprisingly small thread on here earlier after 10.8.1 dropped ..
Recognize that developer ..reliable patch that was checked with another command-line-trim guru .. it was out the day 10.8.1 was released ..

Will keep my eyes open when 10.8.2 and 10.8.3 hit ...

My laptop became much faster once I dropped an 830 in..but it is a Mid 2009 C2D 2.66 that had a 5400 HD in it , and was basically on 24 x7 ... no more beachballs :)
 
Just wanted to say that I'm LOVING the Samsung SSD so far. I've had it for about a week now and everything works perfectly. I have the 512GB model in a mid-2012 MBP 13-inch. Boot time it like 8 seconds to the login screen then about 1 second after logging in. Shut down is about 3-4 seconds.

I have write speeds of about 390 MB/s and read speed of about 480 MB/s. Not sure if there's anything I can do to speed that up but it's fast enough for me.

Thinking about upgrading to 16GB RAM (from 8GB) since it's something I probably need. I run Linux and Windows in VirtualBox frequently nd have lots of software like MATLAB, simulink, labview, etc. running in the background. Not to mention that I'm pretty into photography as a hobby.
 
Free Space Oddity in SSD

Hi, I just installed a Samsung 830 128gb SSD in my Mac Pro (but thought this thread might be best). I followed some online instructions and used Carbon Copy Cloner from my old HDD and only copied the OS and applications.

It now says I have over 30gb free space BUT I continually get "your hard disk is almost full" messages. Even stranger, when I check using 'get info' on the disk, the amount of free space is fluctuating as I watch the window!

It's installed in the optical bay of my 12 core Mac Pro running Lion 10.7.4 with 32GB ram.

Any ideas?

Thanks, Ken

That difference in boot times is just random, and you enabling TRIM is merely a placebo effect. The performance improvement from TRIM takes place behind the scenes during file operations - it's not "noticeable" to the user during real-world use.
 
@Acejam 2K
Thanks for the link.

But surely the 32GB that is supposed to be available (and it is definitely there when I boot from another drive and check the SSD with get info) is plenty of disk space to handle my needs. It's more than 20% of the total.

I wonder if the method of formatting the SSD makes any difference? For example, choosing Partition and selecting 1 (with GUID in the options), or just choosing erase with Mac OS extended (journaled)?

Also, though I know this is a MacBook Pro thread (and I have one of those), the case in point is for a Mac Pro.

Any further elaborations appreciated!
