The great thing is that it doesn't use SMR. I have an 8TB SMR from Seagate and its write performance is bad and variable, much like the pre-TRIM SSDs. It's ok if you write a lot of stuff and then just read it (you can get >100MB/s out of it), but I often see small random writes (updates) at 3-4 IOPS, because it has to re-shingle the whole track.

- electrum 11y agoSMR drives are designed to be used in low-write environments such as archival, so bad performance for small random writes is to be expected.
