OCZ Revo Makes PCI-Express SSDs Affordable

Various expansion card-based SSDs have been around for years now and they're unequivocally the best of the best of the best, sir. With honours, sir! However, they're also the most expensive, by a country mile - we're talking thousands or tens of thousands of pounds. So, to bring near that level of performance to a more consumer level, OCZ has created the Revo.

This PCI-Express x4 card uses two barefoot controllers each controlling half the memory chips and configured in RAID-0. OCZ says the result is the Revo will have 540 MB/s read and 530 MB/s write speeds with a 75k IOPS rating on 4k random writes. SATA drives, in comparison, are limited to around 250MB/s read/write and 50k IOPS. Certainly, the step up in performance won't be noticed by many - most of us are still ecstatic with the change from a hard drive to a half decent SSD, let alone an uber fast one - but for serious users it could well come in useful.

The drives will be avilable in sizes from 128GB to 480GB and OCZ expects them to be only around 12 - 15 percent more expensive than the SATA equivalents (in terms of capacity). This equates to a around £340 for the 128GB and £1,200 for the 480GB one. Not cheap but certainly within the realms of affordability. You can pick one up come the end of the month.

Ah, but can I boot to it? You'd think it would have a BIOS ROM on there to allow you to boot to an installed OS, but I've learnt not to assume that with these PCI-Express SSDs.

Yes, I believe it can. I shall double check tomorrow (in Taipei).

@Ed- Wow! Now there's international service... ;)

I heard that these don't support TRIM. Is this true and if so do they have an alternative wear-levelling system?

This card has the sandforce controllers in it and no it will not support trim. There is still no solution for TRIM to operate in RAID like this card does. While Sandforce does provide its own wear leveling, it is not nearly as effective as TRIM would be.

@DEVAST8: TRIM is not for wear-levelling. It's used for performance purposes. You are right, though, becasue this card uses RAID it doesn't support TRIM but it does have internal garbage collection so performance shouldn't suffer.





@Chris: I've also confirmed that, yes, it is bootable. Indeed OCZ made a point of saying all its PCI-E drives were.

@Ed: Thanks a bunch, much appreciated. I suppose OCZ are more consumer-oriented than other manufacturers, so not such a shock.
