No, i just meant the title name is stupid.. "Even if it's on topic in a forum called audiosex!" However, the example is with 2 identical SSD
In principle, you're right, but in the past, if you were attacked, it was like this—of course, depending on the type of attacker—that the attacker couldn't switch to another partition... Today, as you say, the entire computer system is often affected. It's still advisable not to store any personal data like passwords, PINs, etc. on C. Do everything you can to make it as difficult as possible for criminals.
I have the following setup: desktop has one 1TB ssd (quite expensive as it came out) - at the moment there is still like 200GB empty notebook has only 256GB SSD (quite tight), 512GB would have been better, but well, its okay, for having a few synths installed and a few samples. and then i have a 1TB external ssd with omni (trillian,omni lib), alchemy, Nexus (like only 10 XPs), smaller kontakt libraries and samples. This works just fine, the external ssd has 300MB/s up and down. Loads bigger omni presets, decent fast. Not to mention the external ssd was only like 50€, so not a super expensive one ... for the moment it works just fine.
Considering its 2 identical SSDs, what I was going to mention isn't as important, but still might be useful. If you're going to be doing a ton of "writing" to the SSDs instead of "reading" from then, then I would use whatever drive you plan to write and re-write to most as your secondary drive, and keep your main drive as your boot/system files drive. Larger drives like 1TB and 2TB have much greater TBW performance than smaller drivers so you're good there, but idk if you're going to be editing videos on the drives which can really write a ton of data to them. Also consider the kind of Nand cell arrangement that the drives use (SLC, MLC, QLC) and be aware that the more layers, the lower the TBW performance (usually). Wear on SSDs is definitely not as big of a deal as it used to be, but I've had a couple SSDs go down to like 60% health in CrystalDiskInfo and they start to become unreliable as boot drives in systems I build.
