Seagate IronWolf, 8 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 (ST8000VN004)

I got 6 of the 8 GB versions. I avoided the 10GB becasue it has had historical issues with write caching (perhaps fixed now by firmware update) plu cost per TB was best with the 8GB models. Anyway, back to the review - all 6 seemed to work as expected - they are quiet and fast (for spinners) although one or two seem to get a little warmer than others - possibly because of differing airflows. With a striped mirror (RAID0+1) I get around 700MB/s read and around 450MB/s write real-life use- not too shabby at all. Random speeds drop off a lot obviously. The RAID gives me something like 0.75 GB of write cache (6 disks / 2 * 256MB Cache) which is not to be sniffed at and will significantly improve small random writes. Great disk so far but asks me again in 3 or 4 years if I'm still happy.

Purchased two of the 8TB Ironwolf drives to replace the existing 2TB Ironwolf drives in a Synology DS718+ NAS. I've had the NAS a couple of years and the 2TB drives have functioned without issue but I needed more space. Easy to upgrade the NAS - as some have mentioned, disks are not silent. I can hear occassional rumbles, but not excessively noisy. Drives are showing as 7.3TB each in the NAS, but this is nothing unusual to see lower than advertised storage space.

After purchasing this drive, I never had the time to use until recently. But on trying to initialise it, all I get is an I/O error message. I’ve tried it in several bays on my PC, with various cables, and in different bays on my NAS tower. I’ve also tried it in a friends and my work PC. Still the same error. Not really what I’d expect from Seagate. I’ll have to see if I can still get it replaced and see if the new one works. UPDATE Returned to seller for warranty replacement (cost £28 to send to Florida), only to be informed by the seller after they’d received it that the replacement will be a refurbed drive, not a new one. I did not pay for a refurbed drive, so asked for a refund instead. Their answer was “no”. I’d advise avoiding Tech Dealz (SN Recorded) as they are based in Florida, so returns are expensive. Had to get Amazon to sort this out for me, as the seller was refusing to.

Never happy about the noise levels of these disks, hence 4 not 5 stars, but in every other respect they have proved reliable, originally in a QNAP NAS, now in a couple of old Zyxel back-up NASs. However, with regard to the latter, I had to rewrite the 'init' script of the firmware to accommodate the very slow boot times of these and other Seagate disks.

Works well in my asustor NAS no issues

First arrived with damaged actuators, made a lot of clicking a soon as I plugged it in. Sent it back same day and received a replacement two days later. The new one makes next to no noise and read/write transfer between two of them levels out around 180MB/s, but can surge above 200 at times.

Currently have 4x4TB seagate drives in my Synology DS916+ and wanted to increase the storage capacity. Fitted 2 of these 8TBs and after a few hours of syncing up, they are working fine. Will probably buy 2 more for the full 4x8TB.

Failed after 2 years with only 97Hours use on the clock. It has been used as an offline backup, so powered off most of it's life. SeaTools gave me an error code, so have obtained an RMA to return it to Seagate for replacement under the 3 year warranty. Wish me luck!!!

Zero Complaints.

L'hard disk è arrivato nuovo di fabbrica (controllando tramite test SMART). Avverto che sarà probabilmente necessario contattare il servizio assistenza garanzie di Seagate per rettificare la data di acquisto (inviandogli la ricevuta), dato che viene automaticamente impostata alla data di acquisto al venditore intermediario. È comunque possibile controllare tramite il numero seriale sul sito. Il disco è robusto e solido, mostra velocità di scrittura e lettura comparabili con quelle pubblicate dal venditore. L'unica "pecca", se così vogliamo chiamarla, è che trattandosi di un disco per NAS esso è decisamente più rumoroso rispetto ad un disco da desktop durante la scrittura/lettura. Ovviamente questo è da aspettarsi e personalmente ci ho fatto l'abitudine immediatamente, e riesco a dormirci anche tenendolo in camera da letto. Quando non sta operando è abbastanza silenzioso. La garanzia offerta da Seagate per il recupero dati in caso di rottura e i 7200 rpm sono ciò che me lo ha fatto scegliere rispetto ad un WD red o red plus.

Ik heb op 4 mei 2025 via Amazon een Seagate IronWolf 8TB harde schijf gekocht bij Express IT - Technologies. De schijf is sinds december 2025 volledig defect, hij wordt op geen enkele computer meer herkend. Het product valt nog binnen de garantietermijn. Op 24 januari 2026 heb ik contact opgenomen met het verzoek om vervanging of terugbetaling. De verkoper reageerde zonder concrete oplossing. Op hun verzoek heb ik via Amazon een retour geopend — inmiddels zelfs twee keer — maar daar wordt niet inhoudelijk op gereageerd. Op 13 februari 2026 ontving ik nog een bericht, maar daarna is het opnieuw volledig stil gebleven. Geen retourlabel, geen vervanging, geen terugbetaling. Zeer teleurstellende service en geen betrouwbare garantieafhandeling.

I'been using Iron Wolf disks in my NAS for a number of years. I'm upgrading my existing unRAID server from 10 4TB Iron Wolf Disks to 10 8TB disks. The disks are reliable, perform well and are not noisy.

Esta marca y modelo de disco es el que mas he usado y me han resultado mucho muy buenos, duraderos y, en general, sólidos. Recomendados.
