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. Once installed on a caddy and inserted the array rebuilt by itself. The drive I received showed an old manufacture date, but it was an unused drive.
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. They even have the label on the outside handle that says: "SAS 73GB 15K" just like my old drive trays had, I wish the description had mentioned that they included the mounting trays, since I thought they were bare drives and I ordered extra trays from another...
Summary: Hard to rate such a specific product. I purchased from Aeon Micro and got a great price. It arrived well packaged and each drive with hot swap tray was in a sealed anti-static bag. It is a hot swap SAS drive for PowerEdge X9XX servers. Of course if you are reading this review you probably already knew that...
Summary: There's not really a lot to this, it's a hard drive and a caddy. The caddy is compatible with at least the Dell Poweredge 1950 and probably a bunch of other Poweredge servers as well. I don't know if it's Dell-original or not, but it fits in the slot perfectly, doesn't require any extra force or anything. The hard drive is exactly what it says. It looks like the firmware on it is up-to-date, so kudos there. Perfect replacement drive.
Summary: You can easily tell the quality difference between a 15K RPM SAS drive like this and a disposable SATA drive. A silent 15K RPM platter rotation almost says it all. I've never had a SAS drive fail in any way which is good for owning SAS drives; however, a recent unexpected failure of a SATA drive made me question if I was putting too much confidence in all hard disk technology based on my past experience with SAS drives.
