    ACER returns to our house for a review of the Predator GM7000 2TB NVMe SSD. It does not come equipped with a Phison PS5018-E18 controller, as it turns out. The Acer SSD GM7000 Series features a high-p...

    Sadly the 4K performance of this new drive isnt so good at 4K transfers which is what matters for OS use.
    My Sabrent TLC 1TB pcie gen 3 is a lot faster at most things, slightly slower at Q1T1 reads.

    ie
    The Sabrent tests were taken on my old 6700K system, they will no doubt be a bit faster on a newer system:
    GM7000 vs Sabrent TLC 1TB

    4KB Q32T1
    Read 644.15 vs 957.3
    Write 488.38 vs 846.0

    4K Q1T1
    Read 74.61 vs 67.00
    Write 251.36 vs 389.7


    ps
    also take care when comparing results.
    Many results show Q32T1 figures, others show Q32T16.
    They are not comparable.

    What's the prohibiting factor for the manufacturers to not just increase the cache size? Is it physical space, cost, lack of demand?

    Would doubling the cache allow writes up to 66% of the disk before dropping off? Sorry for the dumb questions, but I'm just not sure why the cache can't be increased if that's what all drives seem to suffer from.

    Yeah, that's expected behavior. That's a link page that will display comments.. However, when you looked, there were not any comments just yet. I guess you expect to get dropped directly into the forums. Check the link again, you will see the comments.
