Western Digital Ultrastar DC HC550 18TB 7200RPM 3.5" SATA Hard Drive WUH721818ALE6L4 (Renewed)

I have installed many of these multi-terabyte HGST drives in the past, and their failure rate is commendably low. Failures do happen with all hard drives, and this brand is known for its reliability.These particular drives came in great condition and worked perfectly upon installation.HGST, now a Western Digital brand, has been one I can trust, and I still do. Will gladly buy more of these as needed.

I've had good luck up until this point purchasing refurbished/renewed drives. Unfortunately with my last order of two 18 TB drives, my luck has changed. One drive was recognized by my system but indicated it had 27k+ hours of use (over 3 years) which in itself is fine, however immediately at idle I found the drive was clicking nonstop every couple of seconds which is generally an indication of imminent failure. Second drive would not spin up and was not recognized in 2 different systems. Perhaps drives were damaged in shipping? In any event, requesting refund.

One thing to check when you buy renewed is the serial number. These checked out and when tested were like brand new drives. I love these.

Llegó en una caja oem sellado bien protegido, al conectar y verificar Hd Sentinel registra excelente estado y cero horas de uso. Ya le pase 9tb de información y e notado de ves en cuando un click de los discos. Hasta ahora bien cualquier fallo actualizare la opinión.

The drives were just as advertised. I even ran them through several of the smart tests and they all passed.

Smart is not reseted.. running time 20000hour &20 uptime. I think it's datacenter's hdd.I bought it thinking about WD's headquarters re-certified product, but it wasn't. I feel very sorry.

I used Crystal Disk Info, a free utility available for download, to check the health of this drive. It revealed that the drive already has an astonishing 31,000 hours of use on it. There's no way I can trust storing photos here, and while I’m keeping the drive for now, it’s already running hot—even in an open-frame case. This is a clear sign that its remaining lifespan is likely short.For anyone looking to replace a large 18+ TB drive, be cautious. Sellers like this are often flipping 3- to 4-year-old used drives for easy profit. With 31,000 hours of wear, this drive should have been priced closer to $50, not sold as a more expensive "deal." It’s common knowledge that once a drive hits 30,000 hours, it’s nearing the end of its life and should be replaced.UPDATE: 3-10-2025Cyclic Redundancy Errors now on both drives that I ordered.....I knew it. I knew it. I knew it.Please read reviews before you plan on using these drives. At 30+ thousand hours, they were replaced for a reason!Funny thing is that the On/Off count was reset but not the hours lol Crystal Disk utility shows you on off counts as well as hours of use. The power on count was 1 when I got them but they were over 30 thousand hours of use.Live and Learn. This company should be ashamed of itself. And they don't respond.

me llego con cero horas de uso, casi nuevo excelente
