Summary: I ordered 6 of these drives (Part #619291-B21) and 4 of the 6 that arrived were Part #653971-00 which won't even fit in our servers. When I sent them back, they sent me ONE replacement drive and it was the same wrong part number!
Summary: Both drives arrived quickly after ordering and in great shape. The packaging was more than sufficient to protect the drives. Installation was a snap and the HP Proliant DL380 G6 server recognized them out of the box. Thanks again!!
Summary: This is a great price and size for a large C partition in a RAID5 type configuration. Inside HP DL380 and ML350 machines they are quiet and reliable. Out of over 200 purchased, I have had 0 defective or have been returned.
