I'd still go for an SSD just to get the best performance possible, along with the advantages of not generating as much heat or noise. But don't get anything high-end, as again the IDE interface will be the bottleneck.SO would you install a ssd or a 7200rpm hd? Thanks.
That one should work with an mSATA to IDE adapter, yes.
I haven't had experience with either of these particular SSDs (though others on this forum probably have), but this one should work fine without an adapter.Without using the adapter, I believe this will work...? : https://www.amazon.com/KingSpec-2-5-inch-Solid-SM2236-Controller/dp/B008RWKFYE/ref=sr_1_3?s=pc&ie=UTF8&qid=1508904863&sr=1-3&keywords=ssd&refinements=p_n_feature_keywords_four_browse-bin:6158690011
As already commented you shouldn't have a problem with that.
TRIM is a command issued by the OS to the drive, it's not built in the drive controller as only the OS knows which blocks are marked as deleted and which not. As far as I know OS X supports Trim starting with Lion, but there is a software called TRIM enabler for SL. That excludes all PPCs from this very useful feature as a SSD slows down over time without TRIM.As already commented you shouldn't have a problem with that.
However I've used several of the following from Transcend as I read that they: 'Support TRIM & NCQ functions, to increase lifespan and performance
Support S.M.A.R.T., to check the status of the player'.
There is no similar mention in the Kingston specs.
Others more knowledegable than myself may be able to comment further on the requirement of TRIM/NCQ functions, S.M.A.R.T support etc with SSD's.
