The Samsung PM961 M.2 NVMe PCIe SSD is an extremely fast data carrier that follows in the footsteps of its already successful predecessor PM951. New to this storage medium are the high-quality TLC chips and the 3D-NAND from our own production. Just like the Polaris controller from Samsung, which provides less waste heat and thus avoids power throttling due to too high temperatures. Read and write speeds and maximum memory capacity have also improved.
M.2 NVMe PCIe SSD with brute read and write speed
With the introduction of the M.2 slot, for connecting SSDs in modular design directly to the mainboard, the already very fast solid state drives achieved a further performance leap, since in most cases this modern slot is no longer connected via the comparatively slow SATA 6G interface with a maximum net data rate of around 550 MB/s, but via several lines of the PCI Express bus of the mainboard. Samsung is once again mixing up this premium class of significantly faster SSDs in M.2 format and presents the PM961, the successor of its rapid predecessor PM951, which now features Samsung TLC 3D-NAND, a Samsung Polaris controller, faster transfer rates and higher capacities.
Since the first final specification of the AHCI protocol for data transmission via SATA interface was already developed in 2004 with mechanical hard disks (HDDs) in mind, it comes as no surprise, that from a technical point of view this now archaic standard is unsuitable for modern flash-based solid state drives (SSDs) - especially if they are connected to the mainboard and CPU via significantly faster PCI Express lanes rather than via SATA.
For this reason, the contemporary NVM Express protocol (mostly abbreviated as NVMe) was created, which was designed entirely for SSDs connected via PCI Express and their hardware potential, which had not been fully utilized up to now, and therefore enables more parallelized data access operations (IOPS), higher transfer rates, lower latencies and far lower command queues. The lower access latencies in conjunction with power-saving modes optimized for PCI Express also result in an overall increase in energy efficiency. The Samsung PM961 M.2 NVMe PCIe SSD continues to take advantage of this new standard and convinces with its performance.
The new Samsung Polaris controller of this latest generation hyper-fast drive, which comes in 2280 format (22 mm wide, 80 mm long), supports four PCI Express lanes of standard 3.0 (max. about 3,900 MB/s possible!). In combination with the built-in Samsung TLC-3D-NAND, the 256 GB version of the Samsung PM961-NVMe offered here offers unprecedented performance potential: With up to 2,800 MB/s (read) and 1,100 MB/s (write), the M.2Drive under PCIe 3.0 and achieves fantastic IOPS values of 250,000 in 4KB read and 180,000 in 4KB write.…more
