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.

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.

Failed after 5 years use. Replaced with a Synology one.

Bought them few years ago and they are doing great so far. Great product.

Brilliant drives. Rather than put them into a NAS, I put them into a RAID array, controlled via an LSI megaraid controller. Pricey, but now I have the ultimate peace of mind that my precious data won't be lost. The performance is good, and the price point is good too. It's a mechanical drive, so it's not blisteringly fast, but with a cacheing controller, games and applications load SUPER fast, and all my database operations run smoothly with low disk queues.

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_VALUE 1 Raw_Read_Error_Rate 0x000f 118 100 006 Pre-fail Always - 179237360 7 Seek_Error_Rate 0x000f 100 253 030 Pre-fail Always - 60121 A 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_VALUE 1 Raw_Read_Error_Rate 0x000b 100 100 016 Pre-fail Always - 0 7 Seek_Error_Rate 0x000b 100 100 067 Pre-fail Always - 0 So actually, as a NAS drive the right name is not Iron Wolf, it is Clay Mongrel.

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).
