    The Sabrent, at least, also has TLC. I guess this is just the norm these days though it make me nervous.

    I wouldn't be surprised if the market at large just moves to QLC for their mainstream products. I was hopping QLC would be a budget alternative to TLC drives, but something tells me that won't be the case.

    Bullshit. Modern SSDs don't work that way. LBAs are not related to internal geometry or allocation patterns whatsoever.

    Guessing there are some firmware woes with the 980 PRO under Linux but haven't yet seen anything to confirm that.
    That would be the first thing to look at but these tests are more or less consistent with a couple of other benchmarks I have seen under windows. Maybe Samsung is being super conservative coming out of the gate across the board. Or maybe these are just designed for a specific use case.

    For me this can't be possible. Everything points to 980 pro must be better then 970 evo in every point
    Just a note: 250 GB SSDs can be much slower than 500+ GB SSDs. The article is using a wide range of capacities: 250, 500, 1000 and 2000 GB.

    You don't say you need to introduce short stroking for SSDs? That was a thing for HDDs only, I thought. :-O

    Phoronix: Samsung 980 PRO PCIe 4.0 NVMe SSD Linux Performance

    The Samsung 980 PRO PCIe 4.0 NVMe solid-state drives are now available from Internet retailers. For those wondering how these SSDs compare with EXT4 under Linux against other PCIe 4.0/3.0 drives, here are a variety of benchmarks.

    I am not sure whether this review can be trusted. There is a very unusual variation in the measured numbers.
