First one I received was DOA, literally a brick, it didn't even show up in the BIOS.
Second one seemed to work fine for a day.
I installed all the recommended Dataplex software and partitioned the drives following OCZ's instructions to the letter.
All seemed fine till the next morning, when all I could get was this black error screen: "Dataplex error - cache drive not found - try rebooting your system".
I must have tried rebooting ten times, no luck.
All my other hardware is top-of-the-line and relatively new; I've had no problems with any of it.
I found out the hard way that the Hybrid HAS to be the primary drive, and OCZ tech told me they have not tested this unit with other Revo drives on the same system (really?). However the user guide that's included gives instructions on how to install the drive as a boot drive AND an additional storage device.
This Hydrid Revo was added to an already existing system with a 100GB Revo as drive C:(which has worked flawlessly for 6 months)this unit was fried in the attempt to combine it with the Hybrid and was sent back to OCZ for a replacement.
(replacement for the damaged drive was received promptly, by the way)
UPDATE: 10/24/11
I'm on my third Revo Hybrid. Second attempt at clean install of windows. Gets as far as showing the drive to install windows then says: "cannot create partition". This has been an exercise in frustration, I've built several computers over the last couple of years and never had so much trouble with any hardware. This is not just a fluke or bad luck, these drives need a little more R&D.
UPDATE: 10/25/11
Got the drive to finally create partitions but won't install Windows on any of them. The same thing happened with the second Hybrid I received. It says: "cannot install windows on this partition, ERROR: 0x80300001". Today when I tried again, the computer simply won't boot. It says: "BOOTMGR is missing. Press ctrl+alt+delete to restart". Great! Everyday a new surprise with this thing. This is really getting tiresome. Now NOTHING boots on the system, not optical, USB or SATA drives, nothing. I'm starting to think that installing this drive has turned my motherboard into $360.00 doorstop. Let's see what OCZ tech says about this.
Final installment of the Revo Hybrid saga:
Tried installing on two other motherboards(Rampage Extreme III and Extreme III Gene) and still had variations of the same problems.
In one instance the drive would not let me install Windows on the HDD but would allow it on the SSD. OCZ tech support was very specific about installing the OS only on the HDD, and that the SSD would only start functioning AFTER installing OCZ's Dataplex software. The back-and-forth emails with OCZ tech support are becoming tedious.
I'm done. Lord knows I tried. I really wanted it to work. Returned the third drive for a refund. I'll use the funds to get another (much more reliable) OCZ Revo SSD instead.
OCZ makes good gear, just not in this specific case IMO. Also the required Dataplex software needs to be revised.

Wow! less than a year on the market and now being sold at half the original price (I paid $500.00).
Looks like OCZ never fixed the problems plaguing this unit and are now trying to dump them.
Your money will be much better spent on a SSD-only 120GB RevoDrive (my 100GB unit still works beautifully)and a 2TB Seagate HDD.
