Second, these days processors are faster with uncompressing than hard drives with writing.
Regarding decompression speed versus write speed, it all depends on the decompression algorithm. Some algorithms are designed to compress slowly and decompress pretty fast while some algorithms may have the opposite property.
Usually, the better the compression ratio, the longer it takes to compress (typical example: lzo vs xz).
Also, modern SSD drives have extremely high throughput, mostly limited by bus connects.

The lens is sitting on my desk... but my X-T30 still hasn't arrived
Great news, Markus.
Once you get your X-T30 and a bit of time for informal testing of the lens, will you mind sharing your impressions?
I see it as the perfect travel lens, but I'm worried it might perform pretty poorly at short focal lengths (< 20mm). Thus, I don't feel like paying almost $900 on a fairly crappy lens :-(
