Initial Test

Pros: Fast
Large Capacity
Low vibration for an 8TB drive spinning at 7200RPM
Cool considering the capacity
QUIET

Cons: None

Other Thoughts: I've only done an initial simple test to ensure it's working correctly.

I know others have said it's noisy. Mine isn't. Yes, there is an audible clicking when the drive first powers on; that has never ever ever been a concern of mine since I'm not using the computer when a drive initializes.

It got a little warm after writing 150GB to it. I did 3 separate writes at 50GB each using 2GB files, using Win7. They were spaced out in time so the drive would run for a while. I didn't run test software. After writing 50GB the write speed was recorded at 216MB/s. This is easily the fastest drive I have. Since Windows 7 shows an average, I can't say that it was writing @ 216MB/s after 50GB was written, I can only say the average write time for writing 50GB at the beginning of the disk is 216MB/s using large files. For a 50GB write I imagine the effects of buffering are still showing in the average (not much), but this is a real world scenario, which testing a drive using other software doesn't really give very well. It gives numbers for you to evaluate the drive in relation to other drives, but real world is writing files from one place to another and then using that data, so of COURSE buffering comes into play for actual drive usage.

The heat is minimal for an 8TB drive spinning at 7200RPM, and it's comparable to the WD NAS 8TB drive that spins at 5400 RPM and doesn't give nearly the performance. Maybe a touch warmer.

I can't speak to reliability since I've only run it for about 1 hr.

When finding this on sale, it's worth every penny in my book.

Solid zero fail drives

Pros: Have many of the 1TB, 2TB and the 4TB sizes of this series in a number of 24/7 commercial servers. Zero failures in over a year.
Yes they make a bit of noise and use some power but only to normal levels expected in a server drive farm.

Cons: None if you are looking for a commercial quality drive for 24/7 server use

Other Thoughts: Can not understand all the negative reviews.
From my experience that are prefect for what they are intended, rock solid server use.

Had to return

Pros: None yet

Cons: Didn't work, buzzing

Other Thoughts: I literally just got all my components for my build, and this drive not only was buzzing every 12 seconds, but it wasn't even recognized. I purchased only premium parts for my system and of all things to not work... Until I get the replacement and see that it performs, I wouldn't recommend buying this drive. Note to everyone here, don't wait for all your parts - once you order you HDD test it in another system to verify it works so that you can return it otherwise.

Seagate has never failed me......until now!

Pros: 256mb cache,5year warranty,normally good quality build. I have had a lot of Seagate drives,including a couple of Seagate Barracuda IDE drives (10years old) still working thank you much!)

Cons: This drive failed less than 90 days after delivery and installation. Now I use it for backup. It seemed to work just fine. Then it started clicking. After 2 days, I've given up and am going to request a RMA.

Other Thoughts: Now to be honest, there have been failures. But as long as the warranty, Seagate has never given me any problems. I will let everyone how things went.

8TB drive, it works, but its loud when idle, like hella loud

Pros: Stores data, its a hard drive I'm not expecting miracles.

Cons: Its hella loud when idle, I have to dd if=/dev/drive of=/dev/null in the background to shut the stupid thing up so it never idles.
The firmware update utility only runs on windows or whatever, in 2018 no less. I don't have windows systems, why is this a thing? Just give me a firmware I can pass to hdparm that I can download. The linux binary that I found seems to have been compiled for some old linux glibc version. A for effort Seagate, F for implementation.

Other Thoughts: I would not recommend this drive to anyone not running windows or that values non 50db when "idle" drives. Seriously how is it louder when its idle. Thats like an italian shop without spaghetti and meatballs, it makes no sense.

Dead on arrival. Replacement drive didn't have the 5 year Seagate warranty. Ordered a 10TB next. What do you know, it was dead on arrival too. What else now??

Pros: Can't get a good drive to write any pros here.

Cons: Must be a reason these are cheaper than WD or other drives. I can't get good drives.

A noticeably faster drive

Pros: Pros-
Longer Warranty
Higher MTBF rating
REALLY Fast-Manf. claims built for speed, and for once, this drive lives up to the claim.

Cons: -Non standard mounting screw points (could pose problem with tray systems) I had to attach to tray with only two

Other Thoughts: As long as these drives are sub $300 I am stocking my system with them, which is the best recommendation I can give a drive
