If you are going to choose the amount of RAM on the machine, more typically is better than less. If you are using Linux (say with VMware Workstation Pro), you need the RAM. If you are using MS Win, understand that MS Win 11 is soon to be released. It is quite likely that MS Win 11 will be a RAM “hog”, particularly for processes such as PL4E DeepPRIME. This depends upon how well MS Win 11 incorporates some of the memory management implementations from MS Win Server (designed for server machines, not end user workstations, unlike enterprise Linux distributions such as Canonical Ubuntu LTS that works on both). In a worst case, make certain that you can increase the RAM. The issue of the relative data rate between SSD and NVMe drives depends upon the drive controller, etc, but in general, that advice also is correct. I personally do not advise keeping all images, both in process and others, on the machine drive, but rather on external devices. Some would recommend storage on the Internet (various virtual drives from different vendors such as Google or Amazon – there are others). The issue there is intellectual property, depending upon where the physical machines that do the actual storage are located, as well as the possibility of corruption were the service to be compromised (“hacked”). The film method of keeping “strip” in physical drawer cabinets, etc, is the equivalent of local (your own, not on the Internet or “web”) storage. I have found that USB removable Tbyte (1, 2, 4, and larger) is suitable; however, indexing these is not so simple. Others I know keep a “disk farm”, with 100 Tbyte of RAID mirrored storage – this requires space, adequate environmental conditions (eg, HVAC), and substantial mains capability with UPS mains backup.
