@ Cat-5 re: PCIe 3 or 4.
Umm.
Currenty, no, the laptop is PCIe 3. So, good point. However, I'm (still) trying to make up my mind on whether to build a PC with both gaming and video editing in mind, or just cop out and get another laptop. It's kinda hanging in the balance. The LT route has advantages, namely buy one box, open, set up and go. The Desktop (DT) has other advantages, like considerably more scope for tweaking spec, and/or adding extra hardware.
Right now, either is possible, but either way,
that will be PCIe 4.
So yup,
this LT won't fully drive the 7000MB end of things but, upon jumping either way, the new one will and, at that point, the new 2TB drive goes in that .... with one exception. One candidate (another Asus Zephyrus like this one but newer gen) already has 2 x 2TB PCIe 4.0 SSDs (in RAID, though I'd want them unraided into 2 separate drives, which I assume shoukdn't be a problem). One issue either way is whether I can still 'downgrade' default W11 installs back to W10. If not, DT it is, with an existing licence.
I was trying to gloss over the whole PCIe 3 v PCIe 4 thing, on TL / DR gounds but should have known I wouldn't get away with it.
Seagate is a strong contender. It's a shame I'm retired journalistically. In the past, I'd have given the press people a call and very likely had a loan unit next day. I even met one of their founders (Finis Conner) several times, though he was running Conner at the tiime, just as Seagate bought them out. Nice guy. But I've been out of the game way too long now, sadly.
