Western Digital 2TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 64 MB Cache, 3.5" - WD20EFRX

After about six months of searching for the perfect drive, I finally settled on two of these Western Digital Red 2TB WD20EFRX hard drives. I was ready to purchase HGST enterprise drives, the former Hitachi, but WD came out with these drives just in-time. I wanted to get the 3TB WD30EFRX version for my Synology DS212 NAS , but the price difference didn't make that much of a sense, and 2TB drives are more than enough for a few years of my home office use. I am very happy that these drives MTBFs are rated at 1,000,000 hours, they use less power, and they are cheaper than other enterprise drives. Upon receiving, I immediately installed them in my NAS. It took about 15 minutes to install DSM 4 and begin the inspection process. I neither chose Raid 1, JBOD, or SHR, and I took some online advice and created two separate volumes, one on each disk, to have two independent file systems. In this case, you don't have to worry about rebuilding disk arrays if any drives fail, and you always have a backup present. I was planning on using Folder Sync feature to sync all folders from Disk 1 to Disk 2 every other hour, but I found out this feature only works on two independent Synology Disk Stations; however, you can use automated backup feature to backup data from Disk 1 into Disk 2, and it produces about the same result as Folder Sync does, and it gives you a few more options for backing up system and application files as well. Synology volume creation took about 7 hours for each drive with automatic bad sector reallocation feature. I later tested each drive with S.M.A.R.T extended test--each took about 4 hours--and I am happy to report that I did not have any bad sectors on either of the drives. That is, the "Reallocated Sector Count" reads zero in S.M.A.R.T report. The drives are surprisingly quiet. I had an enterprise RE2 500GB in my NAS, and it was thunderstorm loud compared to these. The temperature is also very reasonable. When the drive is resting it is about 31C/88F, and under heavy usage it rises up to 35C/95F. Although these drives speed are only 5000 rpm, I don't see any difference in file transfer speed. The only downside that I could sense was the startup time from sleep. I feel that compared to my old WD RE2 drive, it takes a good 2 to 5 seconds more for the NAS to come out of sleep each time. Not a deal breaker, but something to consider when you invest in these drives. I think WD has done a good job with these drives, and they are currently the best on the market for home or home office use. That being said, I still think WD RE4 drives are the best enterprise drives and ultimate in performance; however, if you are looking for a good set of drives for your NAS, and the power consumption and noise are important to you, these WD Red drives will work just fine. Compared to desktop drives, these come with a few enterprise features that come in handy and will save you some time and money down the road.

Fantástico. Lleva 3 años funcionando 24/7 y sin sectores defectuosos.

J'ai commandé 3 de ces disques pour une config en RAID 5 dans ma tour , je n'ai aucun problème pour l'instant. Pas de bruit, vitesse de lecture/écriture très correcte ( en moyenne 25Mbits/s). Le temps de démarrage est aussi correct. Avant d'installer ces disques Avec les SSD utilisés pour les OS, mon pc démarrait en moins de 10s avec les disques et le système de gestion du RAID (IRST) je suis toujours à moins de 20s. L'accès est instantanée pas de de temps d'attente et la consommation des 3 disques en idle ne dépasse pas 1 watt. C'est un bon investissement pour faire du RAID et finir avec les pertes de données.

La Western Digital non ha certo bisogno di presentazioni la si conosce benone e questo Red non è altro che un nuovo prodotto performante e valido è stato pensato per lavorare nei NAS (sistemi sempre collegati ad internet e sempre in funzione con una buona mole di lavoro). Ed è per questo che l'ho preso perché conosco bene la casa e perché questo HD è veramente silenzioso e non scalda ed è stato progettato per essere usato come mulo da soma. Quindi affidabile per i dati, silenzioso e non scalda. Una parentesi a parte che non c'entra col prodotto è data dai WD già boati io li sconsiglio, wd è brava a fare HD e quello deve fare.

Tenia otro disco identico en el PC y me pareció muy rápido y silencioso. Yo siempre instalo dos HD en mis ordenadores. En el primero instalo los programas, que pueden ser 3 ó mas en varias particiones (C, F, G....) y en el segundo HD guardo las fotos, programas sin instalar, utilidades etc. Pero lo más importante es que en este 2º disco hago dos particioes. En la primera partición instalo una copia identica al sistema operativo que uso habitualmente (D) y en la segunda, (E), pongo los backups de todo, usando Acronis, de WD. Si el primer disco se rompe arranco desde el segundo y restauro, en un nuevo disco, todo lo que tenia en el que se rompió. La gente piensa que los HD nunca se estropean, ni fallan, ni se corrompen por un fallo de software. Cuando esto ocurre la sorpresa es mayúscula y francamente desagradable. Si es una empresa, y el disco que falla tiene la contabilidad, le puede costar el cierre.
