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.

    I think I'd trust it more if it were named GOODNAND or GOODFLASH, sure they're good at RAM, but this isn't RAM!

    It's memory and it's random access, so I do think it is technically RAM. It is not DRAM, however, which is what most people think about when they hear RAM.

    Yeah, what if someone thought the company name meant GOO DRAM!

    I have burnt myself on exactly same thing some time ago.

    After some research I have found very few old/diminishing definitions of RAM that would not include SSD - definition I knew.

    And many many times more occurences of what I'd call current definition that includes devices like SSD.

    Hey, maybe they mean ram the animal. Like GOODDOG, only with a goat instead.

    I simply love this comment section! Thank you all for a good laugh! =)

    GODDAMN would be an awesome name.

    I'll just go ahead and post my standard boilerplate peeve: if this is a cpnsumer-grade SSD, then those incredible throughput numbers surely must refer to typical/realistic queue depths as would be likely to occur in consumer scenarios - right? Riiiiiiight.......
  • boeush - Monday, September 9, 2019 - link

    Sorry: "cpnsumer" -> consumer
  • 29a - Monday, September 9, 2019 - link

    My guess is those numbers are at the queue depth that produces the highest results.
