View Full Version : Best way to maintain performance with SSD drive?

Hi,

I've been a happy SD user for a number of years, and backup my primary to a secondary disk automatically each night. With a new MBP on order, I have also ordered a new Corsair Force SSD that I'm going to put into the MBP.

My question is whether there are any good recommendations on how to maintain the high performance the SSD's start out with, since OSX doesn't support the TRIM function used to optimize Windows 7 SSD's periodically.

I was thinking that I backup the internal SSD each night to an external traditional drive, so I have my normal backup. Does it make sense every month or so to wipe the SSD by repartitioning / reformatting then restoring from the external disk back onto the SSD? Since the write cycles on the SSD's allow for > 1,000,000 writes to a single cell, I don't think this approach will cause any problems and it should result in a nicely defragmented SSD each time.

Any thoughts from the experts here?

I really don't think it's necessary. I've been using an ssd on the Shirt Pocket server for quite some time, with a lot more I/O than you would typically be doing, with no problemls at all.

Interesting to hear you are using one on the server :-) I'll probably install all my apps on the normal HD, XSlimmer them, then SD it over to the SDD and put it into the MBP. If the performance starts degrading over a couple of months then I'll try the wipe / restore and see how well it works.

Of course, the performance might not degrade much and 'll just be happy about the whole thing.

Thanks,
Graham
