PX400 NVMe PCIe Gen 3 x2 SSD

By delivering up to 3x better sequential and random performance than SATA III Solid State Drives and much improved latency than AHCI drives, GOODRAM PX400 brings a breath of fresh air within the consumer storage segment. It is suitable to operate as single storage as well as complement hard drives in both desktop and mobile devices. A variety of available capacities, helps fitting into both roles.

Key features
  • Available capacities:
    256 GB 512 GB
  • M.2 2280 form factor
  • PCIe GEN 3 x2 NVMe interface
  • 3D NAND flash technology
  • 3-year warranty + technical support

High performance

By creating a disk based on efficient memory in 3D TLC technology and the Phison PS5008-E8 controller, we  managed to  achieve  sequential transfer  parameters of  up  to  1590 MB/s for reading and 1000 MB/s for write and 200 000 read operations and 160 000 write operations per second (IOPS).

New possibilities with NVMe

NVM Express communication protocol was designed from the ground up to achieve the potentialof fast flash based storage media. By utilizing it in PX400 SSD, we were able to extract the maximum performance from its memory, controller and PCIe Gen 3 x2 interface. NVMe drastically reduces latency and queuing to bring much better responsiveness vs. AHCI-based SSD.

Heat under control

One of the problems that concerns M.2 SSD format is the thermal throttling – limitation of efficiency due to too high ambient temperature. To get it under control, PX400 have special coating  consisting of copper and graphite. Thanks to this, we have obtained very good heat dissipation, without increasing the size of the disk.

3-year warranty & endurance

GOODRAM  PX400 is  available  in  256 and  512  GB  capacities.  All  sizes  are  available in M.2 2280 format, with one-sided placement of elements. As the rest of Goodram SSD’s, PX400 comes up with a 3-year warranty.
