The SK Hynix PC601 1TB m.2 NVMe SSD with Removable HP Heatsink is a high-performance internal SSD that offers read speeds of 3,400 MB/s and write speeds of 2,500 MB/s. With 1TB storage capacity, this SSD is compatible with PCs and features a heatsink compatible with HP's Z2 workstations. The heatsink can be removed and discarded if the form factor doesn't fit your motherboard, but I didn't want to remove it in order to keep the thermal pad intact.
CONDITION: Used but clean. The drive currently has Windows 10 or 11 installed on it, but the license key will likely not be transferrable to a new motherboard, so the drive can be formatted to your preferred specifications.
NOTE: The third image in the listing is a stock image, but this card should look similar if the heatsink is removed.
