I want to create a NAS using the Pi 5 and RADXA Penta SATA HAT and I would like to use an external SSD enclosure to boot off of an NVME SSD for the speed/capacity/reliability benefits.
Should I get an SSD with a DRAM cache or would a cache-less SSD work just as well, considering I'm not using the Pi's PCIe interface and the enclosure/USB port are the more likely bottlenecks?
Also, regarding the drives in the SATA HAT, should those have a DRAM cache or is it not necessary to obtain the best speeds? I do know the Pi's gigabit ethernet speed would be a limiting factor, but it can be partially circumvented through an USB 3.0 ethernet adapter, which I do plan on using.
