This is the Arctic M2 Pro M.2 SSD Heatsink in Black — note this is a cooling accessory for an M.2 NVMe SSD, not a storage drive itself, so it is described here accurately as the accessory it actually is rather than being forced into a storage-device spec table; it appears to be sitting in the SSD subcategory by mistake, and would more accurately belong under a cooling/accessories category. It's a passive heatsink designed to clamp onto a bare M.2 2280 NVMe SSD to draw heat away from the drive's controller and NAND chips during sustained heavy read/write activity, reducing the risk of thermal throttling on fast PCIe Gen4/Gen5 drives that can otherwise slow themselves down once they overheat under a large sustained transfer or long gaming session. Arctic builds it from an aluminium fin-stack design finished in black, aimed at PC builders who want extra cooling assurance for a high-performance NVMe drive, especially in a case with limited airflow around the motherboard's M.2 slots or on a drive that doesn't already have a stock heatsink included from the SSD manufacturer.
