OCZ Shows off RevoDrive X2 PCI-Express SSD
At the ongoing Intel Developer Forum event, OCZ Technology showed off its upcoming RevoDrive X2 PCI-Express SSD. For those unfamiliar with RevoDrive, it is a PCI-Express addon card that holds a couple of SandForce-drive SSDs in an internal (abstract to OS) RAID 0. The SATA bandwidth bottleneck is eliminated, as the drive connects to the system bus over PCI-Express x4. The RevoDrive X2, uses no less than four SandForce-driven SSDs in an internal RAID. The drive connects to the system over PCI-E x4, and is bootable. According to OCZ's internal testing, the drive offers read speeds of up to 740 MB/s, writes of up to 730 MB/s, and 4K random write performance of up to 120,000 IOPS. An IOMeter session running on the demo rig measured 107,124 IOPS live.

sweet!
...but i doubt this is actually faster than 4 single sf-ssds on a proper raid controller.
So 4 x 40gb vertex 2 525$, I'm guessing a 160gb should be under 600$
IMO, great prices. No need to worry about setting up RAID etc. All transparent to the user. Swappable from one PC to the next.
I'll definitely look at the revodrive x2 when it is launched, or even the old revodrive is prices fall when the new one is out. IMO it is good value.

I.e. if you put it in a RAID 0, 1 or 5 group it will not pass TRIM
Or was this addressed with a more recent driver update?
I was hoping the new version with 4 controllers would be 1GB/s+
Or are they being conservative for a change? Seems unlikely.
We should be seeing SATA SSDs with SATA 6GB/s interfaces with 500MB/sec+ speeds before year end, so RAIDing some of those would seem preferable at this point if raw speed is the need.
Or have they finally put the connector for the daughterboard on retail samples and you add a daughterboard to enable 1GB/s to 1.4GB/sec and anothre 50 to 100% capacity? That would be a sweet upgrade path if well priced.
4x 275MB/s x 70% efficiency in RAID = 770MB/s
