I am looking to use an external SSD for use as my main storage for use over a Thunderbolt cable to my iMac. I would like to know if there are any issues like TRIM with this setup and my hardware please?
I have an iMac (27-inch, Mid 2011) and would like to use an Crucial MX200 1TB through a Thunderbolt cable.
iMac, OS X Mavericks (10.9.1), 16GB RAM, late 2011
TRIM or Garbage collection would be handled with the included software that comes with the drive. When installed in a computer you run the software to handle trim. You would have to check if the software works with the drive as an external drive.
Your profile indicates you are still using Mavericks 10.9.1, you can still use TRIM if you want. However if you have upgraded to Yosemite you can still install TRIM but at the risk of lowering security. OWC (www.macsales.com) sells SSDs that use the SandForce 228x Series controller. This controller makes the need for TRIM not necessary.
If TRIM is a primary issue then I'd recommend against the Crucial particularly if you plan to or already are on Yosemite and go with the OWC solution.
My profile is out of date and I am using Yosemite 10.10.3 (14D136).
I plan to use the HDD as my main one, so not sure if I have to install any software or if it just sorts itself out? I suppose I could ring them about that..
It turns out it's fine, I rung Crucial and TRIM is taken care of in Yosemite.
extSSD and iMac issues?
