In Micron's keynote today at (virtual) Computex, the memory manufacturer announced they have started shipping the companies first PCIe 4.0 SSDs, using their latest 176-layer 3D TLC NAND flash memory. The two new product families are the Micron 3400 and 2450 series client SSDs.

The 3400 series is their high-end client SSD, with double the read throughput of their preceding Micron 2300, and 85% higher write throughput. The 3400 uses Micron's latest in-house SSD controller design, and Micron is touting performance and power efficiency that make the drive suitable for applications ranging from notebooks to workstations. As is typical for high-end client PCIe 4.0 SSDs, the capacity options start at 512GB and go up 2TB.

The Micron 2450 series is a more entry-level design but still featuring PCIe 4.0 support. This one uses a third-party DRAMless controller, likely the Phison E19T (also believed to be used in the recently-announced WD Black SN750 SE). The 2450 is available in three different M.2 card lengths from the usual 80mm down to the 30mm card size suitable for extremely compact systems. The Micron 2450 series covers the more mainstream capacity range of 256GB through 1TB.

The most highly-awaited products with Micron's 176L 3D TLC might be the upcoming refreshed Phison E18 drives that threaten to dominate the high-end market segment, but Micron's own 176L SSDs will help bring this latest generation of NAND to a wider range of products, including pre-built systems where OEMs seldom offer options quite as high-end as a Phison E18 drive. Micron's new client SSDs are already in volume production and shipping to customers.

    MSRP; twice what they're worth?

    I'm going to guess yes, as that's been the norm for SSDs for a while now. :(

    Clearly there's some price fixing going on again, the price of 128gb usb/microsd cards has been the same for the last 5 years.

    Price fixing and collusion happens all the time in the flash and RAM industries. They just rarely get caught.

    "They just rarely get caught. "

    They just rarely get prosecuted

    If the various News and Fake News can suss out collusion, so can the various authorities. They just choose to look some other way. Do they get paid to? Only The Shadow knows.

    I haven’t seen the media find any collusion. Only reports of the same law firm bringing up charges that don’t make any coherent sense. This lawfirm had their last collusion case thrown out by the judge.

    You clearly have no idea what you're talking about

    I'm always hoping a variant of the RaspberryPi4 will have an M2. interface, even if it can only communicate via a PCI 2.0 1x channel... It would be nice to add an M2 22x30 256GB drive. :)

    In the meantime...

    Get the carrier board with m.2 and a CM4.

    I don't get the preoccupation with NVMe, on these low-end boards. The Pi is slow enough that SATA vs. NVMe isn't going to make a big difference, if both are properly implemented (i.e. not over USB).

    However, you should keep an eye out for boards with Rockchip RK3588, due out towards the end of this year. Not only does it have PCIe 3.0 x4 (and built-in SATA), but also its CPU cores are much better (4x A76) and it's made on 8 nm in contrast to the Pi's 28 nm.
