Pros: Disks are easy to install. Fans have warning led's and beepers if they stop working.

Cons: Did not supply enough screws for all disks, not a major issue since I have screws.

Overall Review: I have bought 3 of these over 3+ years and all of them are still working, including the fans on even the oldest one. You can see improvements over the earliest model I have to the latest model, but even the oldest ones still work good.

Pros: At least it failed immediately... And I at least put it in a test machine to test before putting it on my machine with live data...the way it died it probably would have crashed it by locking up the SATA bush.

Cons: Never even fully spun up...Seatools software short test failed immediately with an error.

Overall Review: Never buying Seagate again...there is no way the other HD makers can actually be any worse...I have bought 8 disks (6-1.5TB/2-3TB) from Seagate in the last 3.5 years, 2 were immediate DOA's (and had to be RMA'ed), 4 additional of the 3 year old 6-1.5tb had to be RMA'ed before the 3 year warranty ran out.

Pros: NONE

Cons: Needs to be RMAed, and of course WD.com's RMA site also gives an error of STATCODE355 so I will need to try another day.

Overall Review: Based on the error IDNF at LBA I would suspect that this disk is not a CMR disk as SMR disks are the only disks I have seen that error referenced to. The error only happens on writes, which also seems to also indicate SMR. If this was a seek problem causing the error I would also expect errors on reads, but reads just work. NEWEGG: You need to quit putting/transferring reviews of old models with good histories on the new models of disks that have no history. There are 2 separate models of WD RED 6tb with 2 different RPMS and 2 different cache sizes, they are not the same device.

Pros: cheap

Cons: Whoever "refurbished" it failed to do complete testing of the device.

Overall Review: Don't buy a ASUS refurb as they don't appear to know how to test it to see if it actually works. It is still under refurb warranty so hopefully it will get replaced.

Pros: cheap and works reasonable well on smooth floors.

Cons: no replacement/consumbable parts can be found anywhere that I have found

Overall Review: The no parts being available limits its lifetime to when those parts break (side brushes mainly).

Pros: works fast except for some issues under linux.

Cons: On linux under heavy load it can freak out (mdadm raid5/6 builds/checks)...usually if smart commands are being run that makes it rather unstable...to test suggest putting several disks under heavy load and running constant smartctl commands in linux will cause the controller to freak out and drop *ALL* disks connected to it, it will require a reboot to get things back...if it did not have this issue the controller would be great. I have disabled smart and it mostly works...but still if the disk has any error the controller has a habit of freaking out and dropping all disks (even without smart commands running). The error that happens with smart appears to be the same error as this.
