Durability and usability
I bought a pair of 10 TB drives and have used them in my NAS for more than 3 years now. Touch wood it is been a great experience.

So far so good
It is a hard drive. It stores data. I use it in a NAS and it writes as fast as I can send data to it. Not really much can be said about it except it does as advertised.

9.1TB of actual disk space
On setting up it has 9.1TB. That’s a loss of 900GB right from the start , which isn’t a small size , by any measure for the price that I paid for a 10TB drive.

Item was defective from the start but replacement was sent and working fine.
I received the item and installed it into my nas and from the start the drive was making a loud noise as if the disk is rubbing while spinning. Just ordered a replacement. Will update once received. Update: Item received and is working much better than the previous model. Will be changing my rating to 4 stars for the refund and replacement.

Ho acquistato questo hard disk per archiviare film e giochi. Certo non è veloce come un SSD, ma rispetto agli altri dischi meccanici ha 256MB di cache che lo velocizza parecchio. Il rumore è contenuto e non scalda. Western Digital è una marca seria e affidabile. Anche se l'uso consigliato è come elemento di unità RAID, quindi situazioni dove c'è una lettura/scrittura continua, io preferisco usarlo per effettuare miei backup e per parcheggiare collezioni di dischi audio, film, concerti, insomma come memorizzazione dati a lungo termine. Quello che mi ha fatto scegliere questo disco? La possibilità di avere in un'unica unità tutto quello che mi serve a un prezzo per Giga molto conveniente. Ricordatevi che UN SOLO disco non e' un backup, dovrete avere almeno DUE copie di quello che non volete assolutamente perdere (e possibilmente non nello stesso posto fisico). Ne comprerò presto un altro. PRO: GRANDISSIMO, NON C'E' (ANCORA) UN SSD COSI' GRANDE, NON E' TROPPO LENTO, E' CONVENIENTE CONTRO: NON E' UN SSD, COME DISCO PRINCIPALE CONVIENE USARE UN PIU' PICCOLO SSD

Schijf gekocht voor de nieuwe NAS. Snel geleverd maar ik schrok van de verpakking: een kartonnen enveloppe met een enkele laag bubbel theater plastic om de schijf die verder enkel in een anti statische zak zat. Het pakket komt door de brievenbus en valt een meter lager op de vloer. Uitgebreid getest en gelukkig geen defecten gevonden. Dit is wel iets waar Amazon beter over moet nadenken.

This one has just replaced an old one which has been used constantly in my home media server since 2017. Nothing more than a confirmation of longevity of the old unit. I would expect the same from this one.

Je possède 14 wd red, de 3TB à 6TB. Depuis 2015, zéro panne. C'est un sans faute. Mais c'est un succès relatif peut-être pour vous, en fonction de votre utilisation par ex dans un NAS qui tourne 24/24. Mon utilisation est la suivante, je stock mes films dans les wd red pour les visionner sur ma Dune Solo 4K, donc ils n'ont pas un nombre d'heures de vol élevé.

These are fast and most importantly they are quiet. Very quiet. This is not true I understand of the other sizes only the 12TB
