SSD Raid 0 Sequential Write Speed Problem

Hello,

I just got myself a 2nd 520 Intel 120GB and set it up into Raid 0. I am having an issue though. The write speed seems to be messed up.

The reading speed boosted up, almost double (~900). But the Write Speed is only ~300 (while on Linus' vid it was ~400). I can also see the difference when I'm transferring old game folders that I've backup on a eHDD to the computer. I formatted few days before and did the same thing and it was writing normally and faster than today in raid 0.

I've installed Intel Rapid Storage Technology and enabled the write cache which didn't help at all.

Help me guys :D

I'm wondering if it's because the SSD I just got it not working properly.

PS: Linus rocks

Question - are you sure both drives are on a SATA3 port? Or is one or both on a SATA2?

Yep, both are on a SATA3 port, right on top on each other on my MSI Z77A G45.
