PCIe 5.0 SSD based on its new controller, has been shown to Phison for 12 years ...

Phison has just shown off a PCIe 5.0 reference SSD based on its new PS5026-E26 controller and 1TB of Micron''s 3D TLC NAND.

CrystalDiskMark reports that this SSD has surpassed a sequential read speed of 12 GB/s and a sequential write speed of around 10 GB/s. These are fantastic numbers, considering that the flagship PCIe 4.0 drives have surpassed out at around 7 GB/s for sequential transfers.

Despite the fact that 4K random readings at QD1, the most important object for everyday use, is limited to around 16.000 IOPS, while processors like the Samsung 980 Pro can reach up to 22.000 IOPS here. However, these numbers may improve with more advanced firmware in shipping products.

The PS5026-E26, developed by Phison, is the first PCIe 5.0 controller, and it has two ARM Cortex-R5 cores and three proprietary CoXProcessor 2.0 accelerators. It''s built on TSMC''s 12nm process node, and it supports both TLC and QLC NAND flash memory, with data transfer speeds up to 2,400 MT/s.

It''s also worth mentioning that Phison''s engineering sample appears to be using a slightly wider M.2 2580 format factor, although most M.2 SSDs are today using 2280 (the first two points denote width, while the last two points indicate length). This might make these new SSDs incompatible with previous motherboards, although it''s unlikely that anyone would shell out for a premium PCIe 5 SSD and limit its performance by using it on an older platform.

SSDs based on the E26 are expected to hit the market later this year when AMD''s 600-series motherboards will be available.
