Due to shortages in 2242 SSD production we are using a 2230 SSD with an adapter to extend the SSD to 42mm. It does not degrade the performance. High quality 3D TLC NAND for excellent performance The slim design of this M.2 SSD has a 5 layer graphene copper foil heat sink to allow for low power consumption and dissipate heat quickly and efficiently. Most of the 42mm NVMe SSDs are used in ultra books and slimline computers, so a cool operational SSD was high on our feature list. No matter the application or the use, this SSD could outlast your computer!
