OCZ RevoDrive Hybrid Combines HDD and SSD in a Single PCIe Unit
Just like several other SSD manufacturers, OCZ has unveiled several new interesting products at this year’s Computex trade show, including their own approach to the hybrid drive concept; using an SSD as cache memory to a larger hard drive. Their new RevoDrive Hybrid comes with a 60 to 120GB SSD and a 500GB to 1TB hard drive and uses a PCI Express x4 port.
The RevoDrive Hybrid is not yet ready for prime time on the consumer market–the company apparently has difficulties in deciding whether to use a 5,400 or 7,200 RPM hard drive, but according to OCZ, their cache solution is so effective that you could use one at 5400 RPM without sacrificing too much performance.
Nvelo is the name behind the Dataplex software that manages the cache algorithm in the RevoDrive Hybrid, and according to Nvelo, Dataplex provides better performance in PCMark Vantage compared to Intel’s solution Smart Response-
The SSDs that sit on the PCB will be using several SandForce controllers in RAID 0 for higher performance and it is expected that the RevoDrive Hybrid will offer read/write speeds of 575 and 500 MB/s with 30 000 IOPS. One RevoDrive Hybrid gets a 60GB SSD plus a hard disk at 500 GB, while a more expensive version gets a 120GB SSD and a 1TB HDD. The RevoDrive Hybrid is expected to arrive in July with a price tag starting at $350.
