SAMSUNG PM9A1 NVMe SSD, PCIe 4.0 M.2 Type 2280, bulk - 2 TB [MZVL22T0HBLB-00B00]

The Samsung PM9A1 M.2 NVMe PCIe SSD at a glance:
- Modern M.2 NVMe PCIe SSD with 2 TB capacity
- Extremely fast 7,000 / 5,200 MB / s reading / writing
- A total of 1,000,000 / 850,000 IOPS 4KB random read / write
- Samsung Elpis Controller & Samsung 3D-NAND TLC
- Lifetime (MTBF): 1.5 million hours
 -M.2 format with rapid PCIe 4.0 connection

The new Samsung Elpis S4LV003 controller supports eight PCI Express lanes of the 4.0 standard, which make a theoretical reading maximum of around 8,000 MB / s possible! In conjunction with the built-in Samsung 3D-NAND TLC, this 2 TB variant of the Samsung PM9A1 achieves 7,000 MB / s reading and 5,200 MB / s writing as well as IOPS values of 1,000,000 in 4KB read and 850,000 in 4KB read. Write. The modern controller chip also ensures less waste heat and thus anticipates a performance reduction due to excessively high temperatures.

Highly efficient 3D NAND TLC
With the 3D-NAND TLC (or just V-NAND v6) of the Samsung PM9A1, the memory cells are stacked in 136 layers. As a result, on the one hand, larger amounts of memory with higher read and write speeds are possible with a smaller area of the memory blocks, and on the other hand, the service life of the memory is increased and the energy efficiency improved.

NVM Express Protocol
The Samsung PM9A1 also supports the NVM 1.3c Express protocol (NVMe for short), which has been specially developed for modern PCI Express SSDs. This replaces the old AHCI protocol, which dates back to before the general spread of SSDs and is not optimized for highly parallelized data carrier access. NVMe thus ensures significantly lower latencies as well as multiple and deeper command queues, which is reflected in significantly more performance for non-linear transfers such as 4K read / write.
