Hey all,

I am in need of replacing a faulty 4tb drive in my SAS NAS.

It needs to be a 4tb SAS drive.

There are many good deals on ebay for used 4tb drives.

What should I get to eventually replace all 6 of my 4tb SAS drives?

My Current Drives:

X477_SMEGX04TA07

ST4000NM0023

ST4000NM0023

ST4000NM0023 (faulty)

ST4000NM0023

X477_SMEGX04TA07

I’m currently debating between getting

Seagate 4TB 7.2K SAS 6Gb ST4000NM0023 Constellation ES.3 NetApp 108-00315-A0

or

Seagate Enterprise 4TB 7.2K 12G 3.5" SAS HDD ST4000NM0025 1V4207-037

or

Is there better 4tb SAS drives than segate? (HGST, WD, Toshiba, Dell)?

(Assuming SAME price for 4tb SAS drive)

Thoughts?

Thanks for the help!

(I should probably order a replacement asap…)

Edit: the for all the replies. So y’all agree Seagate is the best option ?

    Honestly, are there any HDDs that can really reach 6gb/s speeds? I haven’t seen any that could reach 3gb/s. My current array is all running on SATA-2 backplanes, but with 8 drives in the raid it clocks out at 460MB/s sustained (bytes, not bits). Considering my previous NAS could barely reach 70MB/s on a 6-disk array, I was quite pleased with the new setup.

      12gbps could be useful if you use port expanders to put dozens of drives on the same port, but without a port expander you’re right you wouldn’t saturate the 6gbps channel.

      Imagine a disk shelf of 24 drives being connected by a pair of sas loops. You’d want the faster speeds then. It’s not about individual drives.
