After Effects Cache: logical or physical?

Question

Since we already know that cache discs are important and that we have to keep it on a diferent partition from the instalation/workspace i brought the question: are simply logical partitions (same ssd different partition) enought to work on the best performance possible? or bringing different ssds for each propurse results in the same outcome?

logically when we're working on different ssds each one have full read/write available for each task while in a logical setup both virtual discs, lets say d: and e:, share the read/write values due a hardware limitation.

To brink this discussion to a better level lets say we have the following setup options:

SETUP1 --> 1 ssd 1tb 6000mb read and write

SETUP2 --> 4 ssds 250gb 6000mb read and write

Both are splitted equally on space to System / Adobe Programs / WorkFiles / Cache

No. You are ignoring that your PCI bus has limited bandwidth also. Likewise, using more disks increases overhead for I/O commands, data collisions and sync writes. It's not that simple. On top of it SSDs don't work linear and have their own internal logic. That said, in the end it probably doesn't matter these days. Everything is extremely fast and you have trillions of read/ write cycles, so even the old argument of not wearing out drives doesn't really apply. Everything else is up to the specific configuration and hardware. Plugging a fast SSD into a ten year old motherboard of course will be slower since everything reverts to lower PCI modes and transfer rates compared to newer one...
