Very Quiet; Solid Choice

I chose this over the Black version because I didn't need the top speed and wanted something that would spin down when idle and would be very quiet in operation. This is exceptionally quiet, is working fine, and has a good reputation. I'm using it as a single internal drive, not NAS.

They had a great price on the drives and arrived quickly. I had bought the same ones from Amazon for more. These actually came sealed in original boxes. Amazon ones were sealed in static bags and wrapped in some not so great bubble wrap 😅 (listing said new, but seems like it should have called that out on the listing. Maybe I missed it but the Walmart one was a better purchase)

Would score higher if I could.

Absolutely the best purchase available anywhere. Walmart Really stepped up their e-commerce since rhe Who Knew campaign. I am finding awesome products at best prices anywhere. I am very happy with this product. It was so easy to make operational and I trust the brand for reliability. Thank you for providing me the opportunity to express my appreciation.
