In the race for ever faster storage, manufacturers have increasingly been looking towards the PCIe bus. And while we've seen lots of interesting things out of companies like Fusion-io, it will probably be a few long moments before anything comes around that's feasible, or reasonable, for the consumer. That said, PC Perspective has put in some quality time with the DDRdrive X1, which places 4GB DRAM and 4GB NAND in parallel on a full height PCIe card, keeping that volatile memory of yours safely backed up on a static disk, just in case. According to the reviewer, this device offers the user nothing less than "pure unadulterated random IO" that is "unmatched by any other device available." Other pluses include its cost (I / O operations per second are calculated at about a fifth of the ioDrive) and snappy custom drivers for both 32 and 64-bit members of the Windows family (Linux drivers are promised for the near future). The Cons? This bad boy is currently limited to 4GB, and it'll run you a cool $1495. Not exactly the stuff dreams are made of for 99% of our readers, but if you should happen to find yourself the admin for an enterprise server of some type (as many of us do, from time to time) this might be something worth looking into.
