    Granted, a 5.2TB ioDrive Octal is $85k.

    Oh, and Adaptec has had SSD caching for spindle RAIDs for a long time.

    They also have hybrid RAID that allows you to mix SSDs and spindle drives in a RAID 1 or 10 to reduce costs on RAID with SSD.

    There's plenty of room in the enterprise PCIe SSD space for the LSI WarpDrive and Fusion IO line to co-exist.

    The SAS2008 + Sandforce + NAND cards listed above appear to be a refresh of the previous WarpDrive line, nothing wrong with that.

    Also, LSI previously had a software-based SSD caching options available for their existing MegaRAID controllers called CacheCade:

    The key point for the Adaptec software option that you list above as well as the LSI CacheCade software option is that both of these will improve read performance of your existing HDD RAID arrays by implementing a SSD read cache. Also, with both of these the SSDs aren't integrated with the card.

    The apparent differences with Nytro MegaRAID are that the SSDs are integrated on the card itself (meaning you don't have to trade off HDD capacity for caching SSDs) and according to some of the press releases this is both a read and write cache, so it might be more advanced than CacheCade. This isn't clear but it's possible.

    At any rate, it's nice to see LSI quickly coming out with products that leverage the SandForce acquisition.

    Thank $DEITY that we have software caching that does the exact same thing with garden variety SSDs and HBAs. Reply

    This is where I want to see SSDs going. Wider, current gen PCI-express interfaces, SLC memory so we don't sacrifice longevity or durability, and extremely appealing capacities and transfer speeds. 3.2 TB at 4GB/sec read and/or write?

    Now my big question, is how long will it take for these to become consumer products. That 3.2 TB drive has to be upwards of 20-30 grand if not higher, but what would consumer mass production do for prices? A lot I'd imagine. I've been disappointed with the whole-hearted embrace of MLC technology in the consumer industry, as you're buying a product that won't last more than a handful of years before performance becomes unusable. SLC will give us drives that last decades (hopefully, and if the PCB/controllers can last as long) without significant performance degradation, so now they just have to become affordable!

    I can hope, right?
