Not a great confidence boost.

I just bought two of these drives. They arrived yesterday. One seems to be working fine. The other one never booted up on either of my computers. After multiple failed attempts, I am returning the dead one. I feel lucky that even one of the two drives worked. It’s a sad state of affairs when 50% is the new 100% here at B&H.

I always used WDs never had any issues with them

I bought 3 same 6 TB disks for NAS. their performance are higher than my NAS synology but I choose them due to 5 years warranty and good reliability. Unfortunately these disks pretty hot and sometimes noisy. but for me it is not a problem due to NAS is located in a separate room – I just set up coolers for max rpm.

Got 6 of these drives to upgrade in my NAS replacing old 4TB drives. They came well packaged and I ran badblocks on all of them which took ~6 days to complete all 4 passes and comparisons. All of them passed with no errors and have been up and running for a 3-4 weeks 2/7 with no issue.

I do music, video and photography. I ordered a pair of these Ultrastar 12TB drives to replace a pair of Seagate 4TB drives that were full. Installation was painless. Configured to RAID1, copied data from old drives using Windows Explorer. Everything running great. At my current data usage, I expect to use these for the next 3-4 years. I found this page at the HGST web site. I was able to check the warranty status of new drives by entering serial #. It appears you don’t have to register the drives. Just keep your receipt for a potential warranty claim. I do this for business reasons anyway. Hope this helps. https://www2.hgst.com/portal/site/en/support/warranty/

I wanted to combine a mishmash of HDDs in my PC that have accumulated over the years into a single, large capacity HDD to store files I don’t need on my system disk. This 4TB data center rated Ultrastar is perfect for that! Transfer speeds are good in my system with this disk outperforming both the 2 TB Hitachi and the 300GB WD VelociRapter it replaced.

Bought a four pack of these during most recent sale. Came sealed and well-packaged in four individual retail boxes within the original manufacturer’s four-pack box. Fill Volume with DiskTester revealed very consistent read and write speeds with no evidence of malfunction. Average Read/Write speeds (using Mac file system) over the entire disk was ~ 185 +/- 35 MiB/s for all four drives. All four now installed in TB3 Thunderbay as SoftRAID RAID-4. Running smoothly and quietly. Should have bought a fifth drive while on sale as a backup volume should one of the four drives in the RAID fail. Will probably pay the extra $50 for that mistake. Saved enough by using the PayBoo card to more than cover the difference between sale and non-sale prices though.. Excellent service from B&H as always.

I’ve owned over 50 hard drives. Been using five of the WD Ultrastar 14TB versions for my photo database for over 2 years now, no problems. Do I trust them? Well, I just bought six more 14TB drives.

I always use to buy Hitachi drives. For 20+ years it is all I would put in my computers. Then they were bought out by WD. They are using Hitachi’s technology so I buy WD now. Haven’t had any problems. With this drive I now have 22 terabytes of video storage in my current desk top computer. This one seems a little faster than my two 6 terabyte drives.

Ordered item a few weeks ago to use as a spare drive in a new NAS. The drive unfortunately, is not functional. I now have an overpriced paper weight. Will be interesting to see how/if i can get this replaced.

I’ve used and enjoyed WD drives for years, and have always found them reliable. I recently bought 6 of these to put in a RAID enclosure. 1 of the 6 was DOA. Fine, I know these things can happen (and I’m pretty sure this was the first such occurrence with a WD drive for me). Bought as part of a 2-pack, so had to return 2 to B&H. They shipped 2 new ones, and both were DOA. Tried in multiple enclosures. Same clicking/buzzing sound on all 3 drives and the same error: Could not write to last block of device. So 3 out of 8 drives were bad. QC issues? Not sure; the original bad drive was manufactured in Jul 2020, and the 2 replacements were from Sept 2019. Can’t really evaluate their performance as I’m still waiting to use the working drives. Seems like other people have had better luck.

I bought this to replace a 7-year old Seagate (7200 rpm 1TB) that crashed on me last week. I’ve no complaints about the lifespan of that drive, but saw better reviews for WD (that, and I had a second same-age Seagate drive die within two days). Swapping this drive out for the old one was a breeze, and no complaints thus far. The drive isn’t noisy, and I’ll see how this one holds up.

I purchased 4 drives. Installed them in a brand new server. 2 of the 4 drives failed upon installation. Downloaded the WD drive tester which could not even locate the drives. DRIVEMGR.MSC could see the drive but could not format it. For Enterprise Class drives, very disappointing~

This is originally Hitachi brand. I was expecting Western Digital hard drives.

I purchased this to replace a video drive in my desktop computer. So far so good, really easy to install and format, seems to be very fast. I’m very happy with this purchase!
