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.
| Brand | Model | Controller | Rated Speeds (seq red / write) | Due Out |
|---|---|---|---|---|
| Adata | XPG (model name TBD) | Silicon Motion SM2508 | 14,000 / 12,000 MBps | Possibly 2024 |
| Gigabyte | Aorus Gen5 10000 | Phison E26 | 12,000 / 10,000 MBps | Row 1 - Cell 4 |
| MSI | Spatium M570 Pro | Phison E26 | 12,000 / 10,000 MBps | Q2 or Q3 |
| MSI | Spatium M570 | Phison E26 | 10,000 / 10,000 MBps | Q2 |
| Patriot Memory | Unnamed PCIe 5 SSD | Phison E26 | Row 4 - Cell 3 | Row 4 - Cell 4 |
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.
All of the Phison-powered drives are paired with some kind of 232-layer Micron NAND flash. Any drive which touts a read speed of 10,000 MBps uses the 1,600 MT/s flash, which is due out in Q2. Those with 12,000 MBps reads use the 2,000 MT/s flash which is targeted for late Q2 or early Q3. And those with 14,000 MBps reads need the 2,400 MT/s flash which may come out as late as Q4.
Silicon Motion's 8-channel, 12nm SM2508 controller touts up to 2 million read and write IOPS. It also promises up to 14,000 MBps reads and 12,000 MBps writes.
MSI Spatium M570 Pro / Spatium M570
MSI is coming out with two different SSDs based on the Phison E26 controller. The MSI Spatium M570 Pro combines the E26 with Micron's speedy, 2,000 MT/S NAND flash memory. It touts sequential read and write speeds of 12,000 / 10,000 MBps. The slower, Spatium M570 uses the 1,600 MT/S NAND and is rated for a read speed of only 10,000 MBps.
The M570 Pro has what MSI calls a "next-gen thermal design," with a finned heatsink on top of a flat vapor chamber plate and covered with a geometric shroud. The M570 non-pro has a bronze-colored aluminum heat sink with fins but no vapor chamber. Both drives will be available in 1, 2 or 4TB capacities.
At CES, we got a look not only at MSI's two upcoming PCIe 5.0 SSDs, but we actually got to see some CrystalDiskMark benchmarks of the faster, Spatium M570 Pro in 2TB capacity. Attached to a desktop with high-end specs, the M570 Pro returned sequential read and write speeds of 12,342 and11,814 MBps respectively, which are even higher than the specs. It also had pretty good random 4K numbers as you can see in the screenshot below (should you need to capture your own pics of benchmarks, see our story on how to take screenshots in Windows 10 or 11).
The Spatium M570 is due out in Q2 and the M570 Pro will come later, perhaps still in Q2 or in Q3. No word on pricing.
Adata XPG PCIe 5.0 SSD
At CES, Adata showed off an as-yet-unnamed PCIe 5.0 SSD to be launched under its XPG gaming brand. The XPG SSD is the only one we've seen that will use Silicon Motion's SM2508 controller. It's rated for an impressive 14,000 / 12,000 MBps reads and writes. If it meets the controller's specs, it will also deliver 2 mullion read and write IOPS.
To keep it from overheating, the drive will have a metal heatsink with a fan in it and a stainless steel base plate.
Adata has not announced what type of NAND flash it plans to use with the drive nor did it give an estimated release date. However, SMI reps told us that the SM2508 won't begin mass production until 2024 so, if that's correct, the XPG drive couldn't come out until then.
Gigabyte Aorus Gen5 10000 SSD
Gigabyte was one of the first -- perhaps the first -- to announce a non-enterprise PCIe 5.0 SSD when it disclosed the Aorus Gen5 10000 SSD last summer. It's still not out yet and Gigabyte did not offer a proposed release date when we met with them. However, we'd expect it to launch around the same time as MSI's Spatium M570 Pro, as both have the same components.
Just like the Spatium M570 Pro, the Aorus Gen5 10000 touts read and write speeds of 12,000 / 10,000 MBps. And like MSI's drive, this one will use Micron's 2,000 MT/s NAND.
It comes with either a huge heat sink or without one.
Patriot Memory Unnamed SSD
Patriot also has a PCIe 5 SSD based on the Phison E26 controller and 2,000 MT/S NAND. It has no model name, but it touts the same 12,000 / 10,000 MBps speeds as the Spatium M570 Pro.
The sample we saw at Patriot's CES booth had a giant heatsink and fan on it, but it looks very unfinished so we imagine that there'd at least be some kind of attractive cover above the fan. It will be available in 1 to 4TB capacities (which we think includes a 2TB capacity in there).
No word on availability for the Patriot drive.
