i will use LZ4 compression on a NVME SSD but not sure if 1M would be better than 128k?
Most games really don’t hit the disk that frequently. USUALLY when you have serious storage load while playing games, it’s due to loading enormous amounts of textures when zoning between areas with different resources; for that case, larger record size is better.
But if you somehow manage to come across a game that does a ton of tiny reads and writes–enough to actually make a dent in your storage performance–larger record size would make the lag much, MUCH worse.
maybe 256K would be a better compromise then?
Do you have an actual problem to solve, or are you just minmaxing?
256K is certainly safer than 1M. But it’s still not all that likely that this will impact gameplay much, because storage in general rarely impacts gameplay much.
