The USB C to M2 SSD Enclosure allows you to connect an M.2 NVMe SSD to your computer via the USB C port. The enclosure is compact making it very portable. Please note that while this is an M.2 enclosure it only supports an NVMe SSD. The NVMe technology allows faster speeds over the alternative NGFF which is SATA based. If needed there are two thermal pads and a heat plate to help cooling. Easy to open just press down on the indicator and pull back to remove the cover. For best installation of an SSD insert it at an angle and then press down until it clips in place.
