I've used sillworks now a bunch of times, and they're awesome. Drives are shipped very fast, which is good because I need a reliable source for replacing drives...they are often similar or lower in cost than Dell and can get them to me faster (for devices that are out of warranty).

Sillworks.com had the exact, hard to find, out of production server hard drive that I needed. Next day delivery was as expected. The device appears to be an HP original hard drive. I have not installed it yet, as it is sitting on the shelf as a spare, so I cannot vouch for its performance or longevity. The OEM HP hard drive that this one will replace eventually, spun for seven years continuously and suffered heavy reads and writes during that time, so they exceed mean time to failure, and my expectations.
