The SSD Peperaio Hardware is a solid-state drive in the 2.5" form factor, launched in 2024. It is only available in the 320 GB capacity listed on this page. With the rest of the system, the SSD Peperaio Hardware interfaces using a SATA 6 Gbps connection. The SSD controller is the SM2259XT2 from Silicon Motion, a DRAM cache is not available. SSD Peperaio has installed 176-layer pSLC NAND flash on the Hardware, the flash chips are made by Micron. The Hardware is rated for sequential read speeds of up to 540 MB/s and 500 MB/s write; random IO reaches 70K IOPS for read and 76K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. SSD Peperaio guarantees an endurance rating of 3413 TBW, a very high value, making this drive a good choice for write-intensive enterprise applications.
