Description
MZVKW1T0HMLH-000H1 Samsung SM961 Series 1TB MLC PCI Express 3.0 x4 NVMe M.2 2280 Internal Solid State Drive (SSD)
The Samsung SM961 was a solid-state drive in the M.2 2280 form factor, launched on April 15th, 2016, that is no longer in production. It was available in capacities ranging from 512 GB to 1 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Samsung SM961 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the Polaris (S4LP077X01-8030) from Samsung, a DRAM cache chip is available. Samsung has installed 48-layer MLC NAND flash on the SM961, the flash chips are made by Samsung. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The SM961 is rated for sequential read speeds of up to 3,200 MB/s and 1,800 MB/s write; random IOPS reach up to 450K for reads and 320K for writes.
High-performance 1TB NVMe PCIe Gen3 x4 M.2 2280 SSD designed for modern laptops, desktops, workstations, and mini PCs. Using the PCI Express 3.0 x4 interface and NVMe protocol, this drive delivers dramatically faster boot times and application loads compared with 2.5″ SATA or M.2 SATA SSDs. Ideal as a primary OS drive or high-speed scratch disk for content creation, CAD, virtualization, and gaming systems that support M.2 NVMe.
This model is for M.2 PCIe NVMe slots only. It is not compatible with M.2 SATA-only slots.
