OCZ is definitely pushing its SSD products to the consumer and it was no different when we stopped by the OCZ suite at Computex 2011. The most interesting devices came in the form of PCI Express based SSDs including the pending RevoDrive 3 model that upgrades the SSD controllers to SandForce 2200 models and gets some pretty hefty performance boosts because of it.
The RevoDrive 3 includes a pair of SF-2200 controllers and was rated at 900 MB/s read and 700 MB/s write using the PCIe x4 interface. The 240GB model is apparently only going to have a $599 price tag and it should be available in a matter of a short few weeks. The X2 model adds another module to the mix and doubles the controller count to four and improves performance to as high as 1500 MB/s read and 1200 MB/s write. Obviously these types of devices are only for those that REALLY need to push the envelope in storage performance.
Also, more good news: OCZ has implemented a newer firmware feature on the RevoDrive 3 (and other newer PCIe based models) that will enable support for features like TRIM natively. This is done by hiding the multiple controllers from the operating system and passing on / delegating the TRIM commands as needed. Allyn will have more on this when we get a sample later this month.
Another new PCIe-based SSD was the new Z-Drive R4 that fits more into the enterprise market with insanely high IOPS and performance.
OCZ actually showed a server running a pair of the R4 88 models that were able to achieve a 1 million IOPS rating on random 4K.
Another option for consumers was the new RevoDrive Hybrid that is exactly what it sounds like it is - a combination of a PCI Express SSD and a standard 2.5-in spindle based drive on a single unit. This will bring the performance benefits of not only an SSD but a PCIE SSD to consumers that want to have the appearance of a single large hard drive inside their system. It will use SandForce SF-2200 controllers and is rated at 575 MB/s read and 500 MB/s writes with several models planned for production. The SSD portion that acts as the cache will be available in either 60GB of 120GB capacities while the HDD will start at 500GB and go up from there. Pricing will apparently start at $400 for the 60GB/500GB version and will definitely be appealing for enthusiasts. Now everyone can get the advantages of hybrid storage without being locked into the Z68 chipset or even an Intel platform at all.
This implementation does not use any kind of Intel technology at all and instead is based on a firmware option from NVELO called Dataplex. Based on the marketing numbers we saw the implementation that OCZ has created with the PCIe-based SSD will outperform Intel's SATA-based SRT technology by a noticeable margin, at least in benchmarks. We can't wait to get our hands on one to see for ourselves.
Finally, OCZ is going to throw their hat into the ring with the mSATA offering called the Devena 2 that runs on a SandForce SF-2181/2141 controller. Expect to see this marketed as an option even for Intel SRT. It looks like the rest of 2011 will be very busy for Allyn and our storage test bed.
For the past few months, we've seen rumors upon rumors of a hybrid combination of the H67 and P67 chipsets into a 'Z' series. As the storage editor, I don't normally focus on a chipset update unless there is a corresponding increase in SATA bus speeds and/or ports available on the newer product.
This time things were different. While the Z series had the same SATA bandwidth specs as its older brothers, there was an extra feature that was rather huge in the storage world: Smart Response Technology.
