Even though it’s hot in Las Vegas, the THESE is the opportunity for more “fresh” new products from Phison, the king of controllers SSD.
The PCI Express Gen 5 “revolution” has not yet touched the world of graphics cards. On the other hand, 2023 will have marked the arrival of the first SSDs to this new standard.
If the speeds have indeed soared, the transition to PCIe Gen 5 was accompanied by a significant rise in temperatures which Phison therefore promises to curb, at least in part.
PCIe Gen 5 is heating up…
Since July 2023, we have been able to test four SSDs in PCIe Gen 5 technology at Clubic. Four models from the biggest names: Corsair MP700 and MP700 Pro, Crucial T700 and Seagate Firecuda 540.
Each time, we were impressed by speeds significantly higher than 10 GB/s, for reading or writing. However, manufacturers also agreed to impose the use of an active cooling system – that is, with a fan – on their creations.
Without such a system, it is impossible to avoid exceeding – as clearly as quickly – 70°C on the controller and the throttling effect to lower performance and contain this heating.
… but a little less in 7 nm!
At CES 2024, in Las Vegas, the SSD controller specialist – which is found on most models and the aforementioned brands – presented four new chips.
Four components signed Phison, some of which benefit from TSMC’s 7 nm process while the chips previously used such as the PS5026-E26 are engraved in 12 nm. Thus, the brand highlighted the PS5031-E31T, a PCIe Gen 5 controller without DRAM and equipped with a four-channel interface for a maximum supported capacity of 8 TB with up to 10.8 GB/s of throughput and 1500K IOPS.
At the highest end, Phison presented the PS5026-E26 Max14um, a variant of the E26 mentioned previously and designed for Micron B58R NAND flash chips capable of exploiting transfer channels of 2,400 MT/s. Such channels should make it possible to exceed 14 GB/s in reading and according to Phison, the E26 Max14um is the first controller to exceed 1,000 MB/s on the three tests of the PCMark 10 bench.
The PS5027-E27T and PS2251-21 (U21) concluded the Phison announcements. The first is a DRAM-less PCIe Gen 4 controller designed to pair with 2230 SSDs in portable consoles. The second is an all-in-one chip designed to take advantage of the USB4 interface at 40 Gbps.
