Review on Seagate Cheetah 15K.7 300 GB SAS 6 Gb/s Internal Bare Drive: High Performance, 15000RPM, 16MB Cache by Kenneth Foster

Although the model number is exactly the same, it is NOT a suitable replacement for a Dell branded hard drive of the same model number. When I connected one of them to our RAID, the size was different by 0.12GB and the RAID was not rebuilt. If you need a hard drive to replace your hard drive on a Dell server, especially if it is part of a RAID array, this is NOT the product. I hope this helps someone else make a bad purchase. Further cooperation with the seller on the return was excellent.
