All the PCIe 5.0 SSDs Coming Out in the Next Year or So
We finally have some model names for upcoming PCIe 5.0 drives.
www.tomshardware.com, Jan. 09, 2023 –
The world has been waiting for PCIe 5.0 SSDs to arrive since Intel's Alder Lake CPUs, the first to support the standard, launched in 2021. We passed through 2022 without a non-Enterprise PCIe 5.0 drive available for purchase, but 2023 seems like the year when consumer SSDs will start shipping.
At CES, we saw five different PCIe 5.0 SSDs that are supposed to ship in the foreseeable future, albeit in many cases not until quite a bit later in the year or perhaps early next. The companies showing off the drives were those not known for making their own controllers or NAND so most of the drives rely on the Phison E26 controller that we benchmarked recently. One of them will work with the Silicon Motion (SMI) SM2508.
PCIe 5.0 Controllers
Most of the drives we've seen rely on the Phison PS5026-E26 (or E26 for short). This 12nm controller has 8 channels and promises up to 2400 MT/S with a theoretical maximum sequential read speed of 14,000 MBps and a sequential write speed of up to 11,800 MBps. None of the drives is rated for speeds quite that high.
The Phison E26 also boasts up to 1.5 million read IOPS and 2 million writer IOPS. To achieve maximum speeds, a drive would have to have ideal firmware and very fast NAND flash.
