Actual formatted storage capacity may vary. For details, please visit Toshiba's Consumer HDD website. (2) Compatibility may vary depending on user’s hardware configuration & operating system. (3) Product specifications, colors, configurations and components are subject to change without notice. (4) "2.5-inch" & "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size. (5) For "Drive Bays Supported", please contact your Solutions Provider as compatibility with host device will vary based on the system. (6) Workload is a measure of the data throughput of the year, and it is defined as the amount of data written, read or verified by commands from the host system. (7) MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; It is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF. (8) Read and write speed may vary depending on the host device, read and write conditions, and file size.

Unexpected good deals on NAS/storage at Walmart.

This is a very good NAS drive for the money. I had been looking at WD and Seagate, but they were not available locally and were days out on Amazon. Walmart had these in stock and provided free same-day delivery! I had not been considering Toshiba at all, but after seeing them on the Walmart site, I did some research and discovered they are quite good, albeit considered a bit louder than the others. That is not a problem for me, as the NAS is in a closet. I also bought the NAS (UGREEN DH4300 Plus) from Walmart because the price was $50 less than Amazon and was also delivered free the same day. I now check Walmart for everything I would possibly buy from Amazon because you just never know what great deals are there!

Good deal on a very good hard drive.

Quality drive at a good price. These drives are going up in price per other vendors who are back ordered and are showing new prices when the new shipment of drives come in between June 2026 and July 2026. The AI datacenter buildout is causing all related hardware to go up in price and the Iran war and gas price increases is making the inflation even worse. So recommend picking up hardware before more price increases come along.

I love it because walmart is the only place that had it for the lowest price anywhere and if they get more at the same low price, I'll get another. This is also a drive with 5 years warranty. So far walmart is my new amazon. They deliver on both the price and shipping because I don't have to pay anything or wait for my items to ship to me after I pay for them.
