Even with ssds you can have issues like reading one byte at a time, saturating the sata link, etc

For what kind of workloads would a slower SSD be a significant bottleneck?

Sustainable read/write speeds are also different than peak on SSD vs RAM.

How would the performance compare to a SSD?

SSDs read fast, write much slower for anything which is bigger than a few hundred megabytes.

The controller on the SSD is probably faster than the CPU.

It’s worth noting nvme and ssds make this possible. If this were off an hdd this approach would likely be slower.

Thanks. To add another layer to this, presumably SSD read/write is faster so there would be less time at max usage?

On a Gen4 NVME with 7/6Gb read/writing speeds, I'm sure you can afford that performance hit.

Fast disks are only faster by a factor of two.
