In a few years, the solid state drive in your computer may no longer look as it does today. At least, if a coalition of technology vendors have their way. Dell, EMC, IBM, Intel and a variety of others are trying to push out SATA connectivity for drives in favor of PCIe based connections.
While there are already PCIe drives for sale today, they’re typically 2 or 3 times as expensive as a traditional SATA based SSD drive. However, despite the price, they’re attractive because they are typically 5 or 6 times as fast in raw read/write speeds. PCIe is a lower latency connection because it doesn’t require any bridging chips to access the storage.
But while the interface will change to PCIe, the form factor of the current 2.5″ drive will stay the same. The coalition also wants to ensure hot plug capability to allow for faster online servicing and higher availability in server applications.
The group expects drives based on the new interface to be available as early as 2011.
