Is Switch 2's 256gb on par or worse than PS5's 825 launch model?

Yes and no. It's much slower than the PS5's 5.5GB/s SSD. It's slower than the Xbox Series SDD but not by near as much. 2.4GB/s vs. 2.1GB/s. The Xbox Series SSD has mid-tier PCIE 3.0 transfer speeds. A fast 3.0 SSD will give you over 3GB/s.

That's true for sequential read speeds, but regarding random IOPS and even sequential writes, UFS 3.1 storage is more comparable to a SATA SSD than even a modest NVMe like that Xbox Series one.

The NVMe standard consumes way more power than UFS, so yeah, no surprise in these results.

IIRC the write speed for UFS 3.1 is 1.2GB/s which is still about double SATA SSD speeds of 600MB/s. I'm curious how well the compression/de-compression hardware block on the Switch 2 performs. SD Express Cards only hit around 900MB/s which is slower than internal 256GB UFS memory of the platform. The load time tests for the UFS, SD Express, and Switch 2 cards will be interesting when the comparison eventually gets done.
