Some get close to 300, like 285MB/sec, but you don't get
that for the entire volume of course. It means the
other end is around 140MB/sec or so.

At one time, the only way to hit 300, was with the 15K drives.
But now you can get there at 7200RPM.

A more typical value might be 265MB/sec. Maybe one of the
Black Friday specials would be a bit off the top rate.

And using a 20TB drive as a boot drive, one of the
reasons that's not going to be popular, is the increased
startup time, while that pig spins up. That's one
of the things the small drives had going for them,
is they were set up to become ready faster. (5 seconds versus
22 seconds.)

    "Using the default cluster size of 4 KB, the maximum NTFS volume size is 16 TB minus 4 KB."

And that means, your C: can't be bigger than 16TB, because
C: has a requirement to be using 4KB clusters. If you bought a
20TB to use as a boot drive, you could make C: 16TB and leave
4TB for D: sort of thing :-)

But the maintenance time on something that big, that's not
something to look forward to. I was practicing my data recovery
skills for the last couple days, and the error-tolerating
cloning software I was using, seemed to be running at 3MB/sec.
That's a good reason right there to stick with a 1TB boot HDD.

And 1TB drives aren't really available any more anyway. The
last time I looked, of all things, there were 500GB drives
listed (I thought those were gone), but the 1TB models were missing,
and the next size was 2TB. And some 6TB drives were replaced with
8TB models (likely same number of platters). A 6TB or 8TB
(air breather) could be used as a boot drive. If you buy something
bigger than that, it just takes too long to get the data off them,
or to rearrange them.

The big drives will always be good for backups... The backup
software might not go faster than about 300MB/sec anyway
(whether the source is SATA or NVMe).
