I'm not sure what you mean by test it out. All these do is aid the SSD in keeping sectors with deleted files free for being written to again.

I mean testing in general terms to see how much faster things are. For example I have tried some games and loaded a few apps.
You won't notice any difference by enabling TRIM on a new SSD. However if you had an SSD in operation for some time with much of its storage space utilized and then enabled TRIM, you probably would see some storage space regained and an improvement in performance. With a new drive and enabling TRIM now, you help keep it running in great condition from it's initial in-service date.
Cheers guys! I'll make the appropriate changes! Thanks again everyone for the contribution to the thread, it honestly pushed me to have the confidence to do the upgrade and to do it myself. Definitely wasn't as bad as I thought it would be! As far as the 840 Pro, such an awesome drive for me to use as my first SSD, it's changed my laptop experience!

Not sure if you mean a speed test, but the BlackMagic app from the App Store seems to be a popular choice for measuring out the speed of the SSD.
Hi guys, I need an expert!!
I have a mini late 2012 shipped with a 1Tb hard drive
I added a Samsung 840pro 128go SSD, updated it to the last firmware on a PC, did also a quick test using samsung magician, no errors
I added also a cable bought on ebay.
I use a 512GB USB hard drive as time machine
I'm experiencing various trouble:
- I've installed Sophos but never been able to complete au full scan
- Sometimes an application, for example firefox, systematically crashes. If i reboot the computer, the same application might work like a charm
- I've tried security patch 2013-003 but then rebooting made the computer to crash. I performed a restoration using time machine
- The last time machine has been difficult, ML said the hard drive was defective but it has always worked perfectly.
I also remark that so far none of my files has been corrupted.
Here is what I've tried:
- Checked the memory on a PC => no errors
- Repair permissions => errors related to some iTunes files comes, I ask to correct them, doesn't seem to work
- Enabling TRIM on the SSD
What do you advise me to do?

I would remove the anti-virus software as it isn't necessary (Mac Virus/Malware Info). Then I'd create a new user profile for testing purposes. Set up the new profile and use it as you would your normal one for a day or two and see if the same problems persist. If they don't, then you know there may be a glitch of sorts in your normal user profile.
That would be the first steps I would take.
so i've had my ssd installed for some time now and it's working out great - but i noticed that since i got it installed, i haven't heard my fan spin faster to cool down a heating mbp. i read that ssds run cooler, but how can i confirm that the fan is working as expected and indeed spins faster when the computer surpasses a certain temperature? i'm guessing i can install something to monitor cpu temp - what is the preferred app, and what is the highest safe temperature so i can test this without blowing up my mbp? also, should i just rip a dvd to get the temperature up, or is there something else you guys do to stress it out?
thanks in advance!
thanks in advance!
The SSD does run cooler than a HDD since there are no moving parts causing friction which generates a lot of heat.
You download iStat Menues (14-day trial) or iStat Pro (free) to measure your fan speeds among a host of other things.
Thanks for your answer, I've desinstalled Sophos and created a new account:
- I've forgot to say that viewing photos using preview often causes it to crash specially on raw (which are quite big files). The same problem still occurs, and on any of the accounts
- Haven't tried to update the time machine
- Haven't got so far difficulties to launch programs.
If I understand correctly, you did, in fact, create a new user account and the problem persists?
yes
Earlier, you wrote this:
If I understand that correctly, this problem of app crashes was happening prior to installing the SSD. Is that right?
No: I bought the mini and the SSD at the same time and always used it as a fusion drive. Since the beginning i did backups using time machine. I dit something like 10 or 20 backup without problems but the last one was quite hard to do.
This morning, I installed ML on a external hard drive and stressed preview using 123 big raw files. When I do that booting on fusion drive, Preview crashes very often, I can't view no more than 20 photos before a crash. But while booting on the external drive, I was able to view 123 photos without any problems. That tends to indicate that the problem is located to:
- Either the operating system on the mini, corrupted maybe by Sophos => I can try a fresh install by download
- Either The storage of the mini: I don't think it's related to the hard drive cause I don't hear any suspect noise and none of my user files has been corrupted. It can be the SSD, but If I want to test the SSD I have to use samsung magician which works only on windows :/.
It can also be the cable: I've read that a bad quality cable may not support SSD due to the noise generated by high volume of data. But if I switch the HDD and the SSD, I would put away the problem right?
First, I wasn't aware you set this up as a fusion and I don't have any experience that I could use to assist with that. Secondly, I seriously doubt Sophos corrupted or had an affect thus creating the problems - it just wasn't a necessary thing to have on a Mac.
The issue probably lies with the fusion drive set up and/or the cables, as you mentioned.
When the apps crash, have you looked at the error messages and Console to see what is going on?
So I might have my first issue.
First, here are the laptops stats to show what I'm working with
Early 2011 2.2ghz
8gb of Ram
840 Pro and original HDD
Final Cut Pro X
Now the issue, I've been trying to edit some videos that are all on the HDD, and the App on the SSD, but for some reason, it seems that my rendering process is now longer. Anyone else have this issue, or is not really an issue at all? To specify, I took a time-lapse, added it into FCP X, change the duration which caused FCP X to render the new edit for preview, previously, I felt that in a minute or two it was complete, however now I'm looking at a 5 min. render for a short 15 second clip.

In this case, I don't believe the SSD or HDD are relevant. Once you load your project and ready it for rendering, it's all in the RAM and being processed from there. Once its rendered, it'll be written to the SSD or HDD (whichever you've designated to write it to).
The length in rendering is in your RAM and CPU.
Late 2011 15" 2.2 i7 MacBook Pro OSX 10.8.4
8GB Samsung RAM & the 250GB 840
Read speed:503.3
Write speed:250.4
I have not enabled TRIM and assumed it came with the newest firmware.
I have a question though:
My CPU temps have gone up by at least 50 deg. F after installing the SSD.
It used to be in the high 90's and low 100's (Fahrenheit) and now it's anywhere from 140-170.
I made a thread about it since I couldn't really find any answers but it has not had a lot of traffic so I figured I'd ask here.
So, I'm wondering what other people's CPU temps are and why I am seeing a spike in heat.
The computer does not physically feel hotter than before and the fans do not appear to be working any harder either.
I am getting fan speed and temperature data from iStat Pro.
Also, it has been in for a few days and all major indexing is done it seems and nothing looks out of place in activity monitor.

Not entirely true, it doesn't process in memory and then send to disk. When rendering it streams the output to disk, so disk I/O is a part of the rendering process. However, I have not seen rendering be a disk-bound process so it SHOULDN'T be the cause of slow rendering. For example, transcoding/rendering a 15 minute video results in about a 25MB/sec constant write stream to disk.
Fast disk/access is needed for reading/seeking the optimized media or streaming reads to/writes from an external video source. Rendering is all about CPU.
Putting in an SSD should not have any kind of temperature affect like what you describe.
When the temp is that hot, what is the load on the CPU like and using Activity Monitor, which process is using up a lot of CPU?
Yes, you are correct and I misstated what I meant to say. Thanks!
Of course those numbers are always changing but to me nothing seems out of place.
Currently at 160 deg. F and fan speed around 3500rpm
(took this a few min. after the first pic.)
Well the Flash pluigin for Firefox seems to be running at 25%. Have you tried updating or uninstalling the plugin to see if your temps go down as well as CPU cycles?
Nope! I'm pretty sure I only had the one tab open with macrumors. Firefox iTunes activity monitor and mail were the only applications open.
