Seagate1TB Constellation SAS 6Gb/s 64MB Cache 2.5-Inch Internal Bare Drive (ST91000640SS)

I've now purchased 5 of these drives over the course of about the last 15 months (between September 2021 and January 2023) from 3 different sellers on both Amazon and Newegg.Let's face facts -- these are "new old stock" (meaning that someone has a bunch of these drives sitting around, they've never been opened, and they're trying to get rid of them). The ones that I purchased were all manufactured sometime in either 2013 or 2014. But that said -- they're still awesome drives. Every single one of them has had zero (or close to zero) power-on hours upon plugging them in. They're still chugging along without issues. And given how big they are, you're going to be hard-pressed to find anything bigger for less money.Keep in mind, these are SAS drives -- not SATA! If you don't what SAS is, chances are this drive won't work on your machine!

Used for a Dell PowerVault MD1220. Significantly cheaper than the Dell authorized ones. Downside is that Dell OpenManage can tell its not a Dell certified drive and throws a warning and some random alerts appear in the log file. The drives still work though if you are willing to deal with the false alarm. I generally stick with authorized Dell hard drives for server equipment but these are out of warranty and soon to be replaced anyway so its not worth paying almost 3 times more for Dell drives. Its the same model as the Dell drives, but Dell makes custom firmware that these don't come with.

Excellent work. Everything was very good

Ordered 2 at the same time as a Dell R610. These arrived first with the disk rails. Once the R610 arrived, I installed both of these disks and both worked as expected. The only reason I gave durability a 4 is because the disks have only been used for about 2 hours now so I really don't know how durable they are but no issues so far. I did run a block scan on both and neither showed any issues so I expect these will last a while.

The item was received a day early which was great! I installed it into an HP ProLiant ML110 Gen9 Server. It works great / as expected. The item was packaged well. It is a new drive.

If you're contemplating the build-out of a home/office server, the Seagate 1TB Constellation is a good drive to use. If paired with an SSD for the OS, the Seagate Constellation can handle the other server operations and file requirements. I use 4 of these drives in an ICY DOCK MB324SP-B ExpressCage that well fits these drives...just use some dry graphite on the ExpressCage fans to get longer life out of it.

Replaced a failing drive in a mirror. All green lights.

I have ordered 6 drives total and checked all of the smart data before I actually formatted and started using them. Each drive was under 2 hours of power on time with no errors after an initial warm up session all off the drives reported good with 0 sector faults. I will be buying more of them.
