Seagate IronWolf, 12 TB, NAS, Internal Hard Drive, CMR, 3.5 Inch, SATA, 6GB/s, 5,400 RPM, 256MB Cache, for RAID Network Attached Storage, 3 year Rescue Services (ST12000VN0007)

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.

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

I bought this drive to use in an WD Diskless My Cloud EX4 Network Attached Storage - NAS - WDBWWD0000NBK-EESN It's a standard 3.5" sized drive so it slid straight in to the NAS system and once installed was formatted internally. It's a 4TB drive so after formatting the available space is around 3.6TB which is to be expected. The drive is cool and quiet when running, only making the occasional whir when spinning up and down so when sitting in my network cabinet it's inaudible above the fans in the NAS enclosure. Other have covered transfer rates so i won't repeat them here. As expected it's not as fast as a 7200rpm Barracuda but it's built for longevity over speed and when couple with another 3 rives in a raid array it's fast enough for multiple users to access concurrently.

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.

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.

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 ordered two of these drives for my new Synology 218 NAS. The NAS failed to recognise either drive when inserted. I put the drives in my desktop PC to run hardware diagnosis and while the Seagate software could see the drives, it was unable to perform the read or write tests. One of the drives spools up to speed but sounds mechanically damaged inside, the other does not even spool up. Not bad for drives that are meant to be robust and reliable. If they cannot survive the postage process would you trust them as your backup devices? I have to say I am surprised with how they were posted out though. They had a thin layer of bubble wrap around them then were placed in one of the usual Amazon cardboard sleeves, I would have expected protective foam at least. I have now purchased a couple of WD Reds instead.

I use this as an external drive and it works like a charm.

Having run desktop drives for 5+ years, all of my NAS units failed within 1 week of each other. My 5 redundant storage systems became 1 last remaining. These disks are super fast and work perfectly in my Synology NAS systems. They are very quiet & a few degrees cooler than the desktop version. Time will tell if they outlast the Seagate desktop versions they replace. After 1 month use, zero reconnections or errors.

Ho acquistato questo Seagate IronWolf da 4TB per il mio NAS domestico e sono davvero soddisfatto. È molto affidabile, progettato per funzionare senza interruzioni e gestire carichi di lavoro continui. Le prestazioni sono ottime, con velocità di trasferimento costanti e una buona gestione dei dati in RAID. Inoltre, è molto silenzioso durante l’uso, cosa che apprezzo molto soprattutto perché il NAS è in casa. La capacità di 4TB offre ampio spazio per backup e archiviazione di file multimediali. Nel complesso, un prodotto di qualità che consiglio a chi cerca un hard disk robusto e performante per il proprio sistema di archiviazione.

The harddisk works great. I use it for security so it is important that it makes no noise.

Dependable drives, no issues great product
