The main categories here are SF-2100, SF-2200, SF-2500 and SF-2600. The 2500/2600 parts are focused on the enterprise. They’re put through more aggressive testing, their firmware supports enterprise specific features and they support the use of a supercap to minimize dataloss in the event of a power failure. The difference between the SF-2582 and the SF-2682 boils down to one feature: support for non-512B sectors. Whether or not you need support for this really depends on the type of system it’s going into. Some SANs demand non-512B sectors in which case the SF-2682 is the right choice.
The cat is out of the bag, OCZ has not one but two SandForce SF-2000 series based SSDs out on the market now. And performance-wise the consumer level product is even slightly better performing than the enterprise level product at less cost. These indeed are interesting times. The speeds are so fast with the newer SandForce drive controllers that with a SATA 6GB/s drive interface you get speeds close to what could only be purchased on a PCIe based SSD drive array for $1200 or so. The economics of this is getting topsy-turvy, new generations of single drives outdistancing previous top-end products (I’m talking about you Fusion-io and you Violin Memory). SandForce has become the drive controller for the rest of us and with speeds like this 500MB/sec. read and write what more could you possibly ask for? I would say the final bottleneck on the desktop/laptop computer is quickly vanishing and we’ll have to wait and see just how much faster the SSD drives become. My suspicion is now a computer motherboard’s BIOS will slowly creep up to be the last link in the chain of noticeable computer speed. Once we get a full range of UEFI motherboards and fully optimized embedded software to configure them we will have theoretically the fastest personal computers one could possibly design.
