I'm looking to upgrade my computer. PC Pitstop says don't defragment a solid state drive, and that doing so will shorten the useful life of those drives. What about hybrid drives that are a small part solid state, and part 'regular'? Such a Seagate's Momentus XT? Obviously the majority of date resides on the regular part of theat hard drive, and needs to be defragmented? I can't get a clear answer to this question anywhere! Ideas?

This is what Seagate states about their XT drives

Turn off Windows automatic defrag. Like SSDs, Momentus XT works best without frequent defrag.

I'd think that periodically defragmenting a hybrid disk drive is just as useful as with any other mechanical drive. With the hybrid, however, the flash memory cache must be disabled first. There is a group policy setting in Windows 7 for just this purpose.

Computer Configuration\Administrative Templates\System\Disk NV Cache > Turn Off Non Volatile Cache Feature
