HARDWARE & OPERATING SYSTEM SPECS:

Asus Rampage III Extreme running the latest bios.

Windows 7-64 bit.

Two SSD Kingston Hyper X 120 GB EACH = 221GB in RAID 0

What reasons for these slow writes is there a room for improvement or did a miss something while i was settign up RAID0?


Not quite sure if this running under SATA 6 GBPS?


As always your feedback is very much appreciated.

they are about the same as the benchmark of a single disk so im guessing ur RAID config is messed up! or if you are using RAID1 then your fine!

Raid 1 is for backup not speed!
