Most reliable drives I ever purchased. 12/11/2019 3:16:45 PM

Pros: I have had 5 of these running RAID5 array in a Synology 1513 NAS since 9/7/2014. I have had zero issues. 5.5 years later and they are still going.

Cons: None

Overall Review: I have built many PC's/Server's/NAS over the years. I have never had any drives go this long without issue. These are the most reliable drive's I ever had. My only issue now is that I want to have a replacement available on standby (just in case) and the price has more than doubled since I orginally purchased them 5 years ago.

Avoid for desktop RAID, it's very loud (before FW update) and does not mount in many 3.5" drive bays 4/17/2019 11:41:22 PM

Pros: - You may gain the distinction of mounting your drive using velcro and/or tape.
- You might get to utilize some of those empty 5.25" drive bays.

Cons: - Unreliable
- May require a firmware update to mitigate noise. (see "other" below)
- Only has two screw holes (front and back, no middle). Likely will not fit into tool-less drive bays that come in many desktop chassis since they usually utilize front and middle holes.
- I took my drive to a local computer shop and tried about a dozen cases from Antec, Corsair, NZXT, and other popular brands and the drive did not mount securely into their 3.5" bays (the bays utilize middle holes).
- Common 3.5" to 5.25" mounting brackets do not work either since most of them use the middle holes.
- Mounting with velcro and/or tape might not dampen vibration enough which in turn may degrade performance.

Overall Review: [Update 3] The replacement drives Seagate sent have been working fine after several months - Bumped the rating up.

[Update 2] I RMA'd my dead drive and Seagate sent a replacement. No hassles, thankfully. Things got off to a rocky start with these drives, hopefully Seagate will make things right with other customers who experience failures or other issues and have improved newer versions of the drive. +1 egg.

[Update] I ordered two of these and now one is dead after about 14 months. I filed a support ticket with Seagate and they basically told me that I'm out of luck since I can't run their Windows-based diagnostic utility (I run Linux). I sent them output from smartctl showing SAT command failures but they refused to work with that. I don't expect them to support everything but it would be nice if they showed at least some competency with standard, open-source tools that a lot of enterprises use.

For mounting into a 5.25" bay, iStarUSA RP-HDD35V2 brackets worked: https://www.newegg.com/Product/Product.aspx?Item=N82E16816215435&ignorebbr=1

For noise and firmware: My drives came with SC60 firmware and according to the internet SC61 is the newest revision that helps solve the noise issue. Fortunately there is a Linux tool (seaflashlin) for 32 and 64-bit systems, but unfortunately I had to obtain the SC61 firmware from a third-party website since Seagate's website didn't have it listed for my two drives' serial numbers (The FW I found claims to be compatible with Iron Wolf and NAS drives with FW version SC60). Hopefully I'll see an explicitly supported FW version from Seagate, but until then SC61 *seems* to work and makes the noise tolerable.

I added +1 egg to my original rating since with the special mounting brackets and FW update this drive seems to work, albeit with a fair bit of effort on the customer's part (it's not totally defective at least).

Great HDD 4/11/2019 2:00:11 PM

Pros: Running 2 x these in a Synology 2-bay, in SHR mode. Almost 9.5K power-on time on each drive. Never had an issue. Light use storing image and video files. Never used under constant load as if used as a NVR or Plex system. Just always available file storage.

Cons: I'm surprised product only has an average 3 star egg rating? I got two good drives I guess. Only reason I'm giving these up is because I'm upgrading to higher capacity drives.

Overall Review: The following facts apply to both drives I owned:

- 0 bad sectors
- Never failed a SMART test
- Decently quiet

In the past I would have chosen to go with WD/HGST or even Toshiba over a Seagate drive. But these drives restored my faith in the Seagate brand. Would buy again. In fact, replaced these with their ST8000DM004 baby brothers. Only time will tell if they are as care free as these were.

Failed after warranty expired 3/12/2019 6:13:35 PM

Pros: Large capacity, inexpensive storage, ran nearly 24/7 for a little over three years in an external aluminum enclosure

Cons: Died 4 months past the warranty expiration

Overall Review: This NAS drive was used as a Time Machine backup until it failed without warning. Disk Utility was not able to repair. Will think about another brand for my NAS in future.
