1 TB M.2 PCI Express 4.0 Read speed: 5000 MB/s Write speed: 4500 MB/s SLC NVMe 1.4 MP44L M.2 PCIe 4.0 SSD Heat dissipating graphene SSD label. Supporting SLC Cache enhancing work efficiency drastically. Diversified optimization technology for stability, durability, and enhanced reliability. Supporting the latest NVMe standards. S.M.A.R.T. monitoring software. Trustworthy and reliable five-year warranty. Heat dissipating graphene SSD label MP44L M.2 PCIe SSD is the first product to introduce conductive graphene coating on aluminium foil to the SSD label. Less than 1mm thick, the new label design eradicates mechanical interference when assembling. Moreover, together with the onboard M.2 heat sink, the heat dissipating performance is doubled! Supporting SLC Cache enhancing work efficiency drastically MP44L M.2 PCIe SSD adopts the PCIe Gen4x4 interface and supports SLC Cache. Compared with the PCIe Gen3 interface, the performance is more than doubled and drastically enhances work efficienc
