A:Answer Hello Tony, Please be informed that the WD_BLACK SN850 SSD comes in two variants with heatsink. Long load times are obsolete with next-gen PCIe Gen4 technology, reaching irrational read/write speeds up to 7000/5300MB/s**. Arm your system with RGB lighting, an optional heatsink model. Please check with the manufacturer vendor whether the WD drive will fit and support the host device.
