Do Syzygy tablebases not require some cache memory as Gaviota and Nalimov tablebases do?
Or is it assumed that everyone is using SSDs with fast read access instead?

Syzygy let's the operating system supply the cache. Providing your own would be wasteful.

Probably depends on CPU, memory size and disk type. Eugene and I spent a ton of time testing this and found that a good LRU cache was better due to avoiding decompressing a block that is already in cache. Might not hold today, this was in the pentium pro 200 days. OS filesystem cache works well, at the aforementioned extra computational cost.
