had a chance to stop by OCZ and check out the previously announced RevoDrive Hybrid, a PCI-Express x4 card that combines SSD and HDD.
The new RevoDrive Hybrid has an SSD component that can use multiple Sandforce controllers in RAID 0 that will serve as cache for the HDD. OCZ didn't specifiy which HDD you need to use but according to the report over at Techreport.com, it appears that even with a 5,400 RPM drive the RevoDrive Hybrid works like a charm.
OCZ is using Nvelo Dataplex software in order to manage both read and write cache and will work with up to 120 GB of SSD storage. According to Nvelo, Dataplex software offers better pefromance when compared to Intel's recently announced Smart Response tech on Z68 Express chipset. The spec list states that OCZ RevoDrive Hybrid is capable of sustained read and write speeds of up to 575MB/s and 500MB/s, while the random 4KB write is set at 30,000 IOPS.
It appears that OCZ didn't finalize the specs as it still looking for a prefect combination, but early predicitions puts a base model with 500GB HDD and 60GB SSD, while the more expensive one should feature a 1TB HDD and a 120GB SSD. OCZ plans to put the RevoDrive Hybrid on the market as of July with prices at around US $350.
