Seagate Cheetah 15K.7 300 GB 15000RPM SAS 6 Gb/s 16MB Cache 3.5 Inch Internal Bare Drive ST3300657SS

These are probably the most bulletproof mechanical disks on the planet. I've used them for over a decade, and have never had one fail. Ever. I just bought another batch to proactively hot-swap (*) out a bunch that have been in production for more than 5-1/2 years running SQL and other transaction-heavy workloads without missing a beat. And I only replaced them because of their age. They were still running strong with no warnings in the logs. (*) Hot swapped in several production RAID arrays, with zero system downtime. Hot-swap in one new disk, let the array rebuild. Hot-swap another one, let the array rebuild. Lather, rinse, repeat, until the entire array is new disks.

This drive is an awesome replacement for the original drive in my Dell Poweredge server. The price was also incredibly reasonable. I ended up buying two so I will be ready when another one of the original drives in my RAID configuration goes out. The original one had been running non-stop 24x7x365 for 8 years straight. I expect this one to perform equally well.

The listing was for a new SAS HDD, It really should say New Old Stock, with a note about getting old manufacture date drives (I got one that was already 10 years old). But it did work fine and brought the raid array out of degraded in a Dell PowerEdge server. It did come in a Dell caddy which made me think it was a used drive at first, but the seller claims it isn't.

Great drive, reliable and extremely fast. Read speeds rival most workstation class Sata SSD's and write speeds blow them away. I get 200MB/s continuous average read speed (2mb blocks) and 145MB/s continuous average write speed (2mb blocks). Makes really great System Boot disks.

The title description say's it's a 2.5" drive when it is actually a 3.5" drive. The item is great the description is bad.

perfect for replacing those old spindle drives

The price seemed good for what they are, and I had no problems with installation...offline the failed disk, remove, replace with one of these, fire up Dell OME, rebuild. Installed two of these for a client. Almost the easiest money I've made.

hard drive came fast, brand new just as described. perfect

Es ist sehr gut.

First one is defective. However, the supplier gave us another one right after we return the defective one. Thanks!

SASのHDDにしては非常に安くて、古い保証切れのワークステーションの延命のためのリプレースにはお得でした。 HDのキャッシュが少ないですが通常使用にはほとんど差がないように思います。 リプレースは同容量の元のHDDのイメージのバックアップファイルから復元もエラーなく行えました。 駆動音は多少します、うるさいかどうかは個人差がありますが、私は我慢できるレベルです。 （３年経過し劣化してきたHDDの音にくらべればですが） リプレースなので配線もいらないのでいいですが、RAIDされる方は配線別途購入が必要です。 RAID1組まれるときは、同じ型番・同じロットだと同時に壊れる恐れがあるので、多少価格が違いますが２ケ所から購入できるはいいことだと思います。 ２ケ所から購入できるので１年ぐらい時期をずらして私もRAID1で組もうかとも思いましたが、HDDのイメージのバックアップファイルから復元があまりにスムーズだったので、バックアップだけちゃんとやって今はこのままで行こうと思っています。

Fitted in an old Dell Raid 5 server and rebuilt array without a problem.

Funcionou perfeitamente!
