Summary: Works as advertised. I use these drives to add to my RAID 5 configuration on a home server I have. I don't run my server 24/7 so I can't comment on enduring performance but these drives work fine.
Summary: If you are buying one of these drives at this point, you aren't doing any groundbreaking computing. You are just trying to keep an old system alive a little bit longer. I purchased one of these drives to replace a failing drive in a raid 10 array. It works fine in my Dell poweredge 2900.
The 4 drives I bought were EXACT duplicates of my Dell PowerEdge 1950 drives including the trays.

Summary: I am very impressed that these Seagate ST373455SS-DELL CHEETAH 73GB 15K.4 SAS DELL (ST373455SSDELL) drives included the mounting trays. All I had to do is slide out a bad drive and slide in one of these new drives.
Summary: Drive arrived quickly and packaged well. It works as advertised. Wish we could still find some new old stock of these drives but tested system pulls seem to be all there is at this point. The warranty from this company is excellent if they stand behind it.
