I'm doing a major overhaul but don't know which drive to use. I am upgrading to a SanDisk UltraPlus 256SSD as my boot drive (left approx. 60G free). I have a WD Velociraptor 1TB and a Seagate SSHD 1TB to use for the program/user drive. Which one is my best option? And, can I setup the other in a RAID/backup config? System hardware: ASUS P8Z77-M Pro MOB, i7 3770, 16GB ram, nVidia GTX750Ti Vid. Any input, ideas?

Thanks (in advance)

Yeah, SSHD for sure.

Don't start messing around with RAID because they're completely different drives. You could use the other for backup, or just additional storage if needed. But RAID can be used either to boost performance or gain redundancy (data is still available after a drive failure), but you really want identical or similar drives and the benefits are questionable for a home environment anyway.

An SSHD will give you better performance.

A couple of quick draws!

I guess I'll be using the SSHD. I really put some serious thought into using the Velociraptor with its 10k spin. You both say the SSHD is gonna be quicker tho. It would seem I have an item headed to eBay. Anybody wanna buy it? I don't need another hard drive. Already have a home NAS for extra storage. Thanks for your answers.

If you want a bit more of a detailed answer...

The underlying hard drive in the raptor is significantly faster (like maybe 25% or even a little more). So anytime you're reading or writing directly to the HDD, i.e. when you're accessing files that aren't cached, or writing to the drive when the cache is full, will be faster on the 10K drive.

However, obviously, the SSD cache on the SSHD is much faster again than the 10K drive (particularly in random read scenarios like program loads, here the SSDs can be 100 times faster or more). Whereever you're working from cache your SSHD will be much faster.

IMHO, the benefits of the cache, which are massive, outweigh the benefits of the faster underlying drive, which are maybe 20-40% faster.
