Question about Samsung 870 QVO

Samsung Electronics GmbH
Hello,
Thank you for your enquiry.
For the Samsung SSD 870 QVO SATA III 2.5 inch, your device requires a SATA interface as well as a free mounting slot in the 2.5 inch form factor.
SSD stands for Solid State Drive and refers to a purely electronic mass storage device. Similar to a USB stick or a memory card, the SSD uses flash memory chips for data storage and thus does without mechanical components as used in conventional hard disk drives (HDDs).
Kind regards from Schwalbach

Yes, this is 2.5 inches. The unit inch can also simply be written with a ". And so it is in the product title with 2.5" and in the specifications under form factor.

But it is not a hard drive, it is an SSD ;-)
