Finally got my four 80GB Intel x25-m SSD's today (ordered them 3 months ago) so I can post my results! 4 x Intel x25-m G2 SSD's on an XFX 780i motherboard using onboard (software) RAID0;



This is with Windows 7 64-bit default storage controller driver.
The scaling of sequential write performance is great, I have run AS SSD a few times and seen over 320 MB/sec.
This fixes the low sequential write 'issue' for Intel SSD's for me.
Unfortunately the read performance doesn't scale as well as it could for 4 drives, with the 780i chipset limiting the maximum sequential read to 635 MB/sec (although that is more than 3 times more than my previous setup with two 150 GB WD Raptors, so I'm not complaining).
I was curious about the random access times and ran HDTune to get an idea (read only)



DAMN! The 780i chipset is really holding things back but it doesn't matter as four x25-m's in RAID0 blow any mechanical hard drive out of the water.
I wonder how they would perform on a SATA 6 Gb/s PCI-e raid card...
