Handheld gaming PCs have quite specific needs, when it comes to storage. It needs to be very compact, with low power consumption, but offer fast transfers at the same time. SSD controller wizards Phison has launched three new chips at this year's CES event and one of them is the perfect match for SSDs designed for the Steam Deck and other portable PCs.
The most interesting controller announced is the PS5027-E27T. Where the other two are PCIe 5.0, this one uses the older 4.0 specification, but it's still good enough to offer sequential read/writes up to 7400 and 6700MB/s, respectively. The decision to scale the transfer rates back is to keep the power consumption (and therefore heat output) as low as possible, with L1.2 low power state being less than 5mW.
