This seems perfectly normal. Keep in mind "SATA 6Gb/s" means 6 Gigabits per second, not Gigabytes. Most SATA SSDs will read at 500-600 Megabytes per second, and write at even lower. This benchmark uses Megabytes not Megabits, so this ends up being around the correct write speeds for Nvme.
As for RND4K scores, those are random read/write, which is almost always much slower than SEQ, or sequential read/write.
sequentials do seem low. MP510 uses TLC, so it may slow down like this as it gets closer to full capacity.Yeah, i know reads are normal, but aren't those writes a too low? the drive is rated for 2000MB/s. is it normal to get that low when the drive is filled?
