PS5012-E12DC

the Enterprise PCIe SSD

Phison Electronic PS5012-E12DC PCIe Gen 3x4 NVMe SSD is the 2nd generation of our high performance PCIe NVMe SSD controller. Surpassing PS5007-E7DC, the new E12DC pushes the limits of capacities and performance, offering capacities up to 3840GB and sustained performance up to 3200 MB/s in Sequential Reads and 3200 MB/s in Sequential Writes.
Utilizing an advanced 28nm process technology while incorporating LDPC 3.0 ECC engine, CoXProcessor 2.0, DSP 2.0, and E12DC will maximize endurance, reduce latencies, and provide consistent performance on various workloads.

Advanced Features

LDPC 3.0 ECC Engine

Phison’s 3rd generation LDPC ECC Engine can correct up to 160 bits/2k via the hard decoder and up to 400bits/2k via the soft decoder. This will ensure that your data can be protected throughout the life of the SSD.

Power Loss Data Protection

Power loss protection is provided using additional circuitry and capacitors. This gives E12DC additional power and time to flush the data residing in DRAM and buffers. This ensures the data integrity of the drive and protects against data corruption in the event of power loss or system failures.

Encryption

For data security, PS5012-E12DC supports AES 256 bit hardware-based encryption. E12DC is also fully compliant with Trusted Computing Group (TCG) Opal Specification.

End to End Data Protection

From the moment the data enters SSD, E12DC generates associated parities to prevent soft errors. The data is safeguarded from corruption at every step of the way from the host device to NAND flash.
