Used WD Red (CMR) 3TB NAS drives at a great price!
Recently I set up a home network NAS server, two actually; one new and one purchased used on ebay. The used one is a 4-bay unit that arrived with 3 of these WD30EFRX 3TB NAS drives, in a Raid-5 array. That left the fourth bay empty, and as the the 3 WD drives were all matching I opted to find another drive to match them and set up a new array with all four bays in use. These older drives are not the WD Red drives being sold today. The specs appear to be the same, but there's a major difference between these older Red's and today's drives: These drives use CMR technology, while today's Red's use SMR. I'm not going to waste the space defining these terms, but I recommend you research them as to how they differ. If you want the superior CMR in a WD Red NAS drive today you must buy WD Red Plus. There's a big difference in price. Since the 3 WDs I inherited with my NAS server were not new, but in perfect condition with no errors and great specs, I purchased a used drive here on ebay. The price was excellent, shipping was quick and the drive checks out perfectly. Of course, used is used, but let's be real here. I'm running a home network for my pleasure, and to create adequate storage for tons of media and information on all kinds of subjects I've been collecting since the1980's. These WD30EFRX drives are perfect for this! Remember, NAS is for storage, not for backup, so I backup my storage. I'm also watching the drives' conditions for deterioration. You cannot beat the quality of these drives for the prices they are being sold at!
