SAMSUNG SM951-NVME SSD, PCIe M.2 Type 2280-D3-M (NGFF), bulk - 256 GB [MZVPV256HDGL-00000]

With the introduction of M.2 slots to connect SSDs modular performed directly on the mainboard the already very fast solid state drives a further performance boost because of this modern slot in most cases no longer over the comparatively slow SATA 6G interface is connected with a maximum net data rate of 550 MB / s, but over several lines of the PCI Express bus of the mainboard. Samsung mixes these premier of the much faster SSDs in M.2 format now tidy and presents a new version of its rapid SM951, which now instead of AHCI first relies on NVME and four PCIe 3.0 lanes is connected.

Since the first final specification of today generally prevailing AHCI protocol for data transmissions via SATA interface already in 2004, was still being developed solely by mechanical hard disk drives (HDDs) in mind, it is hardly surprising that this technically now archaic standard for modern flash -based Solid State Drives (SSDs) is inappropriate - especially if they are not connected via SATA, but over much faster PCI Express lanes on the motherboard and CPU.

For this reason, the contemporary NVM Express protocol was (usually abbreviated as NVME) launched which was designed entirely on PCI Express connected SSDs and their not yet fully been unused hardware potential and therefore more parallelized data access operations (IOPS), higher allows transfer rates, lower latency and much deeper command queue. The lower access latencies have in conjunction with optimized for PCI Express power modes also an overall increased energy efficiency. The Samsung SM951-NVME M.2 SSD makes itself as one of the first available consumer flash media now exploit this new standard.

The UBX controller this hyper-fast drive the latest generation, which comes in 2280 format (22 mm width, 80 mm length), on top of that support is equal to 4 PCI Express lanes of the standard 3.0 (max. About 3,900 MB / s!) , In conjunction with the built-MLC NAND (16 nm) are due to the offered here 256 GB version of the Samsung SM951-NVME unmatched performance potential: up to 2,000 MB / s (read) and write 1,260 MB / s ( ) operates the M.2-Drive with PCIe 3.0 and here achieved fantastic IOPS of 300,000 in 4KB Read or 100,000 in 4KB write.
