OCZ RevoDrives

Is there any reason why I should look at "traditional" SSDs when these PCI-E drives from OCZ appear to offer really good performance compared to the sata drives?

Yes, they're a little more expensive, but when shopping for an SSD I'm looking at performance first, and price second.
 
I bought one a couple months ago and returned it because it wouldnt stay stable for more than a day at a time. Windows would reboot and have to chkdsk the drive all the time.

Depends. On one hand multiple drives in RAID 0 can perform as well as a RevoDrive X2. On the other hand, on-board chip-sets have strengths and minuses with running multiple drives.

The RevoDrives are fairly to setup since they are basically a Silicon Image chip running Sandforce drives in RAID 0. The big negative I have seen is that the X2's are limited to under 800MB/s. That is better than your average ICH10R RAID 0 at 660MB/s on the X58 platform, but not as good as you can get with higher end PCIe RAID cards and not what the drives are capable of putting out.
 
You'll never come close to 800MB/s in real-world performance. Not even a fourth of that. Those are marketing numbers.
 
cut through mode on 6gbps sata/sas raid cotnrollers will work just as good. the problem here is the monstrous heat and power needs and the lack of "hot-swap" makes this drive unusable in enterprise.

Next gen Intel eMLC (slc+mlc hybrid) will be hot swappable and spread heat across the bays. Spread the power demands across the bays. Spread the hot swap-ability across the bays. Fact is until we see drives pushing 6GBPS (SAS = full duplex) in random i/o nobody really cares about sequential.

I get that all the time on a 4 drive WD Blue array. The OCZRevo drive was giving similar performace, but it would just not stay stable.
 
If one of the 'drives' in the Revo drive dies, you have to RMA the whole thing. If one of your drives dies in your 2 x SSD RAID 1 array, at least you can continue to function while the faulty one is RMA'd.
