Every PC hardware reviewer complains about "SSD is running out of pSLC cache" after writing a few GiBs of data. But it's a pointless exercise unless you are write-heavy (e.g. when you're a YouTuber with 4K videos). Meanwhile, nobody talks about low-depth IOPS. Where are the Windows Update, tar -xf chromium.tar.gz, and npm install simulations? Better, try resilvering a super fragmented RAID-Z2 using an old version of OpenZFS without the sequential resilvering patch.

    @niconiconi@mk.absturztau.be most meaningful metric is fio with direct writes, fsync and depth 1 with write size bigger than possible dram cache size. It will basically show raw nand performance
