Pay Once, Use For Years

HDD Capacity: 8TB

Installed this in my PC as a main data drive. It backup to an 8TB Expansion drive. Pay once, no monthly fees to a 3rd party, and now future proofed for 3-5years for half a day's effort.
Used AI/Chat GPT to help do the installation and setup. No dramas, no double trips across town. Computing in the 21st Century. Love it.

Large - but a tad noisy

HDD Capacity: 12TB

Have two of these in a 6-bay NAS. These Pro drives are a tad noisier than the plain 6Tb drives I already have. However, they are faster and work just fine.

Working great with my Synology NAS

HDD Capacity: 4TB

No issues so far. Installed the drives and they work flawlessly. I was concerned about the noise which some others mentioned however I think theres much bigger things to worry about in the world... Noise by my standards is minimal.

Good value for a quality product

HDD Capacity: 10TB

I recommend this product for the performance, five year warranty, and low noise. A con is that it does not come in any box at all, merely an electrostatic resistant bag.
