At least here, NVMe is not just for backups. Using NVMe for file

computer. NVMe costs a lot per gigabyte and it's a boring
upgrade, but it saves much time every full day of use.

I suspect the OS design isn't good enough for modern hardware.

But that's just a theory of mine.

To give an example, on a test I carried out (using RAMDisks),
NTFS was only able to do certain operations at around 4K per
second. Whereas Linux TMPFS (a RAMDisk) was able to do the same
test at 186K per second.

NTFS may have been a good choice when it was invented around the
year 2000 or so, but it's perhaps a bit long in the tooth now.

One thing I haven't been able to determine, is whether the
"interrupt limiter" on Windows, has been changed radically from
the 10K to 15K per second range it used to be set at. I expect
that modern hardware can profitably go faster than that. I
haven't seen any notes on the issue in my travels. I think
Process Monitor has a counter, and perhaps perfmon.msc has one
too.

I could hardly believe my eyes!!!

I just did a backup and restore, with Macrium on medium
compression. NVMe to NVMe.

Windows Backup C: 29.3 GB, Mring file...13.8 GB. 1 minute 58
seconds Restore to same drive *23 seconds*

I Did it again to make sure, backup 2 minutes 1 second. Restore to
same drive, *22 seconds*. I sat and watched it to make sure I was
fully Awake, Oh and I don't drink or do drugs. :-)

You are doing the restore using a paid-for copy of Macrium Reflect?

Copying from NVMe to NVMe using the Macrium Reflect Free rescue
flash drive from the prompt takes at least 10 minutes (or whatever,
it's a long time). It's no big deal since the restore is done
rarely, I'm just curious.
