I purchased these drives in 2018, so 3 years running, they have been in a Raid 1. Very fast and usable as a working drive with redundancy for photo, video edit, game dev. Programs are on SSDs, with scratch on SSDs. Get these if you want to have a reliable backup. Use the best or cry like the rest. Waiting on the 24TB. 16TB sounds nice.

So far it is working good, it is not completely quiet, but it is quieter than previous WD gold generation, it works cool and looks well made.

Ordered two 12 TB disks at a good price and delivered them right away. Nice job!

These are much quieter then the WD Black HDD.

They are discontinued by Western Digital. DOA.

Great value and perfect for accesible archiving storage.

I bought two of these WD 10TB Ultrastar 7200 rpm SATA internal hard drives for my new CyberPower PC and had B&H install them before they shipped the system to me. The first one is for moving photo files in and out to Adobe Lightroom for processing, the second for backup storage of my photo files. This way I keep these data intensive RAW files (and processed jpgs) off of my main PC drives.

I’ve had it for a week. I can’t seriously evaluate it. It must take some time to know about your performance, etc. I have other WD records and they have worked very well for me, that’s why the 5 stars.

Very nice HDD , less heat, less noise that WD Gold, great value to back your files
Christophe Pagac (verified owner) –
ONLY buy enterprise class hard drives, they cost more but are worth it. Never seen one fail yet… Too bad SATA 3 is still the connection option, for these massive drives, it takes a loooonnggg time to transfer a lot of data.

Sealed drive with helium means no problem with dust ever. Works as it should.

This is the fourth WD 12TB drive I have purchase for my Synology Network Attached Storage device, also purchased from B&H, and I couldn’t be happier with the price, the products and the service. Although the last two drives I purchased were on back order, B&H sent regular emails to let me know I had not been forgotten and this was much appreciated.

We have been running four of these in a Drobo 5D for over a year now. No problems. Don’t understand complaints about noise, since these are usually used in a unit that can be hidden under the desk or away from your ears. Usually the noise comes from cooling fan or other sheet metal of the drive container (Drobo in my case), not the drive itself.

I put 4 of these 2TB drives in a Raid 5 array video surveillance recorder a month ago (NVR4) . They are relatively quite, setup without a glitch, and perform well.
Justine Walter (verified owner) –
I bought these drives to go in my new NAS because I’m hope they are as reliable as my 7 year old 4TB HGST drives. They are a louder than the old model but they are quick.
Brianne Kuhic (verified owner) –
I have about 12 of these (12TB) drives deployed in both a RAID-10 box used for video editing and also in a Synology NAS. They work flawlessly. The challenge I always have in sourcing these is that you can rarely find them in retail packaging with the manufacturer’s 5-year warranty. They are typically sold by people who buy in bulk and sell them in smaller quantities with their own warranty. Fortunately, B&H has come to the rescue, offering them in retail packaging with full manufacturer’s warranty and pricing comparable to what you find for the bulk drives. (The B&H SKU is slightly different but same drives.) I recommend both these drives as well as purchasing them from B&H.

This is my fifth 8 TB version of the HGST heritage drives. The last three are post Western Digital. I also have many 4 TB units from when that was the sweet spot. I’ve had no failures from any of them and the performance has been very good for a spinning disk. In the last year, I’ve been working from all solid state disks and the two units in my video workstation are powered down until I need them. Two others are in canisters off site. I expect them to last a long time in this use case. This purchase is for my local media server which has no redundancy except that all the files still exist where they were created and can rebuilt in the case of a drive failure. I’m not too worried in the short run based on past experience. In the long run, this and every other disk will be policy-replaced when I start to worry.
