Optane 900p sequential mixed read-write performance, compared to a wide range of well reputed consumer SSDs. The graph shows how traditional SSD's performance drops sharply to around 500–700 MB/s for all but nearly-pure read and write tasks, whereas the 3D XPoint device is unaffected and consistently produces around 2200–2400 MB/s throughput in the same test.

There are several limits on DRAM performance. Most noted is the read cycle time, the time between successive read operations to an open row. This time decreased from 10 ns for 100 MHz SDRAM (1 MHz = Hz) to 5 ns for DDR-400, but remained relatively unchanged through DDR2-800 and DDR3-1600 generations. However, by operating the interface ...
NVM Express (NVMe): A modern interface designed specifically for SSDs, NVMe takes full advantage of the parallelism in SSDs, providing significantly lower latency and higher throughput than AHCI.

Historically, most SSDs used buses such as SATA, SAS, or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate for SSDs, which ...

In the event of a power failure, the module copies the data from the volatile traditional DRAM to the persistent flash memory, and copies it back when power is restored. It uses a small backup power source for the module while the data in DRAM is being copied to the flash storage. NVDIMM-P: specification fully released by JEDEC in February 2021 ...
