GOODRAM has introduced its first SSDs featuring a PCIe 4.0 x4 interface designed for new-generation high-end PCs. Set to be available in 500 GB, 1 TB and 2 TB configurations, the drives are based on Phison’s PS5016-E16 controller.

Just like other PCIe 4.0 x4 SSDs powered by the E16, GOODRAM’s IRDM Ultimate X SSDs use 3D TLC NAND memory. From performance point of view, the manufacturer promises up to 5000 MB/s sequential read speed, up to 4500 MB/s sequential write speed as well a 750K read/write random IOPS for 1 TB and 2 TB drives, which is in line with other products based on the Phison’s PS5016-E16 controller. Meanwhile, the cheapest 500 GB version provides a lower write speed as well as random performance.

In a bid to ensure consistent performance under high loads, the GOODRAM IRDM Ultimate X SSDs are equipped with an aluminum heat spreader, which as with other drives suggests a compatibility focus on desktop PCs.

    Bingo, theres no standard so might as well make it look as goodaspossible.

    They are the QD1 of course - or at least they would be if we lived in a better world where we could have the nicest things.

    ... and promptly get sued by GOODRAM. Since there is clear risk of confusion, they'd be right in claiming you were trying to mislead customers.

    I think for anyone who like to invest in a long term upgrade plan is to at least wait for a true native the second generation PCIe 4.0 controllers. These current gen are just PCIe 3.0 controllers with PCIe 4.0 PHY, so they don't get the full benefit, except minor raw bandwidth gain.

    And which consumer is even going to notice the increased speed of these , let alone "true" pcie4.0 ? your games will load .02sec faster ? capacity is king , speed is just a prince!
