Introduction, Packaging and Specifications
Today Allyn looks at the next iteration of the OCZ RevoDrive – the x2! This new card opens up two more channels of throughput over the RevoDrive, demonstrating how well the SI RAID solution can scale with quad-Sandforce units behind it.
Last week OCZ introduced the RevoDrive x2 – the successor to it’s not-so-old RevoDrive. The x2 adds a daughter card with two additional Sandforce controllers, bringing the total to 4, meaning it now uses all of the available channels of the on-board SI RAID controller! Back when the RevoDrive was released, I asked / begged for them to consider a 4-channel variant. At the time they said they were considering it. I can only imagine the RevoDrive took off quickly enough for such a rapid turnaround on the next iteration of this excellent SSD package.
We may as well compare the packaging of all solutions:
The RevoDrive x2 comes packaged much like the RevoDrive did, but now there’s an added bonus – a sticker!
- Capacity: 120GB / 240GB
- Flash type: MLC
- Interface: PCIe 4x (Gen. 1)
- Max read: 740 MB/sec (up from 540)
- Max write: 720 MB/sec (up from 480)
- Sustained write: 600MB/sec (up from 400)
- 4KB random write (aligned): 120,000 IOPS (up from 75,000)
- Seek time: 0.1 ms
- Power consumption: Idle 3W / Active 8W
- BOOTABLE (!)
Other PCIe SSD solutions out there are not bootable (most notable the Fusion-IO line of SSD’s). Since the RevoDrive builds on a simple RAID controller, it sees the same benefits, such as a low footprint driver that can be executed by the Windows installation environment, enabling windows to be installed directly on the RevoDrive itself!.
