Good Drives

Richard HickmanOctober 3, 2025

I bought 2 of these Seagate Exos x12 12TB SATA 6Gb/s 256MB Cache Enterprise Hard Drives because of the price and guarantee. I had a drive go bad in my main NAS, that has been running for over 5 years with renewed drives in it. I've always bought renewed drives for storage. I used these to transfer data from a NAS with the bad drive so I could replace it. They work great, very fast. Recommend for anyone. Read more

Great for long term backup

Bill AOctober 10, 2025

Bought several of these and so far they are performing perfectly. I use them in a separate usb c case and turn them on to backup all of my files weekly. Each had a lot of hours on them but few starts so I imagine they will do well for years to come. Zero errors on any of the drives. Read more

Too many hours on these drives

J. R. GouldSeptember 8, 2024

Both drive have over four years of usage hours on them. I was expecting used drives based on the description, but as backup drives for my photos, I'm worried that since these are past their usable lifespan, they may fail sooner than I was expecting. On the positive side, they have very few bad sectors so I'm guessing that is why they can be described as they are. Will report back if they do fail soon. Read more

Good value per TB

My unit have defects and long history of used for 6.7 years

MelMarch 1, 2025

The media could not be loaded. I hear from other costumers the hard drive it is a little used but man 58528 hours equal 6.7 years that it is insane. Another issue it is the typical noise the hard drive do before to fail very disappointed whit my unit. I will started to return process I am really don't recommend this hard drive refurbished units. First time I will like to try a unit like this but man that it is very frustrating. Speed it is 32mb for seconds wen in the original specified 350 MB for second that means this hard drive it is going really fast to fail son Read more

Great as Backup Drives!

Dickson SwanepoelSeptember 10, 2024

I purchased 2x of these drives. They were well packaged and protected. I have already done an extensive test on one of the drives which already had power on time of more than 1350 days when connected it first. The SMART showed no errors and my Hard Disk Sentinel Surface Test to Reinitialize Disk Surface showed no errors after the scan. So everything is working great on the first disk. The second disk already had power on time of more than 800 days when connected it first. The SMART showed no errors and I will give update once Hard Disk Sentinel Surface Test to Reinitialize Disk Surface has finished. UPDATE: The disk is working perfectly and passed all tests. Overall I am happy with the purchase as both work and will form part of my backup pool. I feel confident and should one fail the pool will recover lost files. Purchasing a new or refurbished drive, any drive can fail at anytime. Saving money on a drive that might last me another 5 years or more is great. Lets see how it goes! Read more

Still Strong After a Year

Mark V. FuscoSeptember 28, 2025

Bought a little over a year ago for external storage in a JBOD box. Pretty rock solid. The only concern is according to DriveDX its Hardware ECC Recovered number/score is 9. But it's been 9 for year and that error code isn't a major indicator of failure compared to others. For all the rest they are well into the green after a year. Read more

Good but….

TwopappakugsOctober 5, 2025

Seems to be ok now I think. When I first got it I had issues initializing it and when writing to it for a period of time, the drive crashes and disconnects. I have to restart to bring it back online. Once I get data on it, it reads just fine and I can transfer data in bulk from just not to. Have to transfer data to this drive in small amounts. Hopefully I’ve got it running more stable. If not I’ll contact the seller as it is supposed to be certified renewed with warranty. Don’t be discouraged though. Even with brand new drives, there are bad units bits a hit or miss when buying an hhd Read more
