I'm selling a high quality hard drive that I simply outgrew a few years back. Its maker is OWC (Other World Computing), an excellent designer and manufacturer of peripheral computer equipment. It's approximately 750 gb. It's been run through the necessary software to ensure it's fully wiped and it seems to run smoothly. I decommissioned it as a backup drive back before the pandemic to bring in a 3 tb drive simply because my business was growing too large. It's been idle since then so the hours on the device are much lower than its age might indicate. You can find current versions of this same drive on the OWC site and other than size and connection ports not much has changed, same rugged yet stylish all aluminum enclosure with "shock isolation". While this is an older drive (last used in 2017) by hard drive standards, it appears to run perfectly, very quiet since it's finless, with not noticeable defects in it's operation.
