Disk I/O: PCI Based SSDs (via makeitfaster)

Great article and lots of hardcore important details like drivers and throughput. It’s early days yet for the PCI based SSDs, so there’s going to be lots of changes and architectures until a great design or a cheap design begins to dominate the market. And while some PCIe cards may not be ready for the Enterprise Data Center, there may be a market in the high end gamer fanboy product segment. Stay Tuned!

Disk I/O: PCI Based SSDs The next step up from a regular sata based Solid State Disk is the PCIe based solid state disk. They bypass the SATA bottleneck and go straight through the PCI-Express bus, and are able to achieve better throughput. The access time is similar to a normal SSD, as that limit is imposed by the NAND chips themselves, and not the controller. So how is this different than taking a high end raid controller in a PCIe slot and slapping 8 or 12 good SSDs o … Read More

      Most of what I’ve read so far believe it or not is from TheRegister.com. They have kept up with the press releases as new announcements come out. And Tom’s Hardware has done desktop-style benchmarking to show the performance versus single SSD’s installed on an average desktop PC. However as you pointed out, prices are at a premium and the ‘desktop’ Fusion-io product is still in the high $600-$700 MSRP. It’s appeal is going to be very limited. I didn’t know until I read your article that it also eats RAM as part of it’s design. So that makes Fusion-io doubly limited in it’s appeal. Good info to have.
