Pros: Fast and fairly quiet

Cons: None so far.

Overall Review: Note that if you hook this up directly to your motherboard make certain its RPM is within specs. When I hooked it up to my board it would only spin at 900rpm and wasn't moving much air, there are no options to change voltage on my board so I am not sure why it wasn't running at full speed. I thought it was defective at first until I tried another fan with the same results. I then hooked it up via the 4pin molex and it then spun at 1300rpm and moved a lot more air.

Pros: - 4TB - Cheap

Cons: - Its extremely slow, I'm not sure if I have a defective unit or if SMR drives really are just that extremely slow. I did not get any kernel errors other than a few usb resets over the 22h test so I think its just that slow. I used the *nix dc3dd utility from DoD Cyber Crime Center (dc3.mil) and over the entire drive the average sequential write was only 49M/s and read was 98 M/s. Note that is not the slowest speed, its the overall average! # dc3dd hwipe=/dev/sdh hash=md5 pat=FF verb=on dc3dd 7.2.641 started at 2016-12-03 01:47:35 -0600 compiled options: command line: dc3dd hwipe=/dev/sdh hash=md5 pat=FF verb=on device size: 7814037167 sectors (probed), 4,000,787,029,504 bytes sector size: 512 bytes (probed) 4000787029504 bytes ( 3.6 T ) copied ( 100% ), 78618 s, 49 M/s 4000787029504 bytes ( 3.6 T ) hashed ( 100% ), 38793 s, 98 M/s input results for pattern `FF': 7814037167 sectors in 4d9759bd7709041538e9dd73bffc1a46 (md5) output results for device `/dev/sdh': 7814037167 sectors out [ok] 4d9759bd7709041538e9dd73bffc1a46 (md5) dc3dd completed at 2016-12-03 23:37:53 -0600

Overall Review: Recommended only for archival use due to how extremely slow it is.

Pros: Great price

Cons: Hard to use due to incorrect screw hole size

Overall Review: The holes on the side to mount in the case are not standard 3.5" HDD size. The included hardware will fit a 2.5" drive, but this adapter is meant to install a 2.5" drive in place of a 3.5" drive. This might not be a problem depending on your case type, but mine requires special screws to mount a hard drive so the holes being the wrong size was a pita. And as another reviewer noted this requires a 6-32 UNC tap to correct the problem properly, which may be hard to source locally.

Pros: * Silent * Runs very cool

Cons: * DOA

Overall Review: Bought this to replace a very old fanless dual dvi card driving two 1920x1200 monitors. As soon as it was installed though video corruption issues began on the DVI-D (black) port. Hopefully RMA for a replacement unit will correct the issue.
