The number of hard drive bays and NVMe slots is undoubtedly the most essential aspect of a Network-Attached Storage, as you wouldn’t want to be stuck with a 2-bay NAS with limited HDD capacity if you plan to house TBs of data on your storage workstation. But I’ve often seen newcomers disregard the RAM specs when picking up a new NAS. On paper, going for more than 4GB of RAM might sound like an unnecessary investment for a storage server, especially with the memory apocalypse causing DDR5 (and even DDR4) modules to hit obscenely high prices. But if you’re planning to work with TrueNAS or other hardcore server distros that are built on ZFS, it’s a good idea to arm your backup machine with ample memory.
