Question Should I install OS on Gen4 or Gen5 NVMe SSD ?

[MaxT2]

If everything goes well, next week I should be up with a computer made of new and some re-used parts.

My target is productivity performances/productivity features. So, gaming performances are not a priority, but comfort for everyday use is. Biggest bottlenecks are photo editing, video editing, running some virtual machines (Virtual Box) and various heavy-or-not computing tasks.

The permanent drives in it will be:

1. NVMe Gen5 Crucial T700 4TB
2. NVMe Gen4 Samsung 990 Pro 4TB
3. NVMe Gen4 Samsung 980 Pro 2TB (reused from current computer)
4. SATA Western Digital Gold 18 TB

Motherboard will be Asus Z890 Maximum Hero.

My question is: on what drive should I install Windows 11 Pro? The most likely options I see are

1. On the Gen5 drive?
2. On the new 4 TB Gen4 drive. Leaving the Gen5 drive at rest and dedicating to demanding project files.
3. (Maybe on the old 2TB Gen4, but I think, rather on the 4TB.)

I think of option #2 as I read that OS doesn't benefit much from being on Gen5 drives and these heat a lot.

I'd install it on the slower SSD, in this case that would be the PCIe4.0 SSD however in daily tasks, you won't be able to tell the difference between PCIe 4.0 and PCIe 5.0 speeds.

I would put it on the 2TB 980. Leave the larger drives for project files.
