Seagate IronWolf, 3TB, NAS, Internal Hard Drive, CMR, 3.5 Inch, SATA, 6GB/s, 5,900 RPM, 64MB Cache, for RAID Network Attached Storage, 3 year Rescue Services (ST3000VN007)

Worked flawlessly for 7 years. Died on a speed test. Was compatible with the Synology NAS I bought them for. Did show bad sectors build-up a few weeks prior to sudden death. On death the drive no longer starts up and double clicks on startup.

A little early to tell, as I've only had them a little while, but looking good so far. Bought 2 of these to replace a couple WD red 3TB drives for my main server, replaced fine in freenas 11. And the 2x 3TB drives went into my backup NAS. Haven't noticed any difference in operation at all, all going as well as ever, they may actually be a little quieter than the reds, but as I'm not that near the server most of the time wouldn't notice that much anyway, but they did sound quieter when the resilvering was taking place and I had the case open. Very good value, seeing as they were approx £20 cheaper than WD red 4TB drives at the time I bought these. Main reason I bought these over the reds though is that WD seem to be "foggy" over how much warranty these drives should have I have read in forums.These drives have the full warranty, I registered them soon as I got them, little tip, when you get ANY HDDs to save yourself problems down the road take pictures of the sticker so you have that info available for entering warranty details. I also use it for identifying drives if they fail, as the picture is named sda for example in freenas OS, then I know is is the first SATA connection drive... and I can locate that info on the seagate warranty page for requesting RMA for example. Hopefully it'll be a while before that happens as these drives are supposed to have a pretty good MTBF and amount of data writes per year.

I bought this as a replacement for a failing drive in my Synology DS218+ NAS.Hot swap successful, rebuilt the RAD storage pool automatically, no errors, has been running since with no reported problems.The original drive began failing with increased bad sectors after nearly four years (35,000 hours) of continuous use. Its partner, still in the NAS is still going with no errors, (touch wood).

I bought 4 of these to go into a QNAP TS-x53Be NAS, what I didn't realise is that these drives have a "feature" that causes constant disk activity - thanks to something called BMS (which apparently does background medium scanning to prolong the life of the drives). Qnap forum explains all... but wish I'd known as I would have bought from a different manufacturer given I'm using Raid configuration and this is just another level of overkill - plus it's in the living room and brings the WAF down several points! At least one star removed for that reason.

Bought this disk to replace the failing 3TB Disk in my Ubuntu File Server which is loaded with 24TBs with ZFS. Easy swap. Id highly recommend these disks if your running some sort of a File Server or Storage Server as your regular Desktop Disks have less of a lifespam when on 24/7. The old disk i replaced with the New 3TB NAS Disk was in the File Server for 3 years.These Disks dont really get warm like regular Desktop Disks.Recommend running a long full Smart Test Overnight on any new Disk.Will order some more to Replace other Disks.These disks dont give out much vibration like Desktop Disks.Would i recommend these Disks?Yes if your going to be installing in a NAS or a Linux File Server or any other Storage Server.I would not recommend installing in a Desktop or a Workstation as a boot drive.Would be okay to use in a Workstation or Desktop as a Storage Drive.Would i recommend without Redundancy? No any disk can fail even when its new.These Disks are good if your stacking them in a backplane in a Server Chassis or NAS Chassis.Cons?None it does it job.

Once you are past the first 1 -1.5TB the seek error rate goes through the ceiling and the performance drops in half.Actual data:This drive:ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE1 Raw_Read_Error_Rate 0x000f 118 100 006 Pre-fail Always - 1792373607 Seek_Error_Rate 0x000f 100 253 030 Pre-fail Always - 60121A HGST Drive with which it is paired in the NAS for RAID1 purposes (gets same read/write requests):ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE1 Raw_Read_Error_Rate 0x000b 100 100 016 Pre-fail Always - 07 Seek_Error_Rate 0x000b 100 100 067 Pre-fail Always - 0So actually, as a NAS drive the right name is not Iron Wolf, it is Clay Mongrel.

I’m expecting this review to be rejected as it’s not painting Amazon in a good light, but as there’s no way to complain I will continue to submit until I get a response, for as long as it takes!I’ve been using Ironwolf drives for some time now and they’re proving to be reliable, much better reliability than the old Barracuda drives from Seagate. My only issue is the clowns that package such a delicate piece of electronic hardware in a flimsy cardboard envelope. They’ll send out a pack of batteries in a two foot square box surrounded by air pillows, but risk damage to precision engineered mechanical hard drives in packaging that will happily fit through the letterbox only to go crashing to the floor doing all kinds of unseen damage (as the delivery driver has no indication as to how delicate the contents are...)No more hard drive orders from Amazon for me, the risk of damage is too great.
