SSHD, single or dual in RAID?

Hi all!

I've recently run out of room on my HDD and so was on the lookout for another when I came across SSHD's. For only £10-£20 extra over conventional HDD's for 3-4x the performance I can see no reason why not to go SSHD. However, I'm not sure whether to get 2 x 1tb SSHD's and set them up in RAID 0 or just get one 2tb SSHD? Which would offer more performance?

I understand that HDD's benefit immensly from RAID 0, but SSD's in RAID 0 offer little difference. So does anyone know what sort of performance difference you would get with 2 SSHD's in RAID 0?

I do know that 2 drives in RAID 0 doubles the chance of drive failure, as if one drive goes down both are rendered inoperable. But this is something that I am not overly bothered about as I dont keep any important data on my internal drives, all this is backed up onto two external drives for extra redundancy.

If anyone could explain to me which would offer the msot performance, 2 drives or 1, I would greatly appreciate it!

Granted, but even SSD's can't run at full 6Gb/s right now, so two SSHD's in RAID 0 will surely pull less than 6Gb/s? I believe Seagate rate thier SSHD's @ ~150-160mb/s, so theoretically 2 in RAID 0 would pull a maximum data transfer rate of ~ 300-320mb/s?
