I guess I was overreacting as the
2TB is faster.

The sustained speed is faster on the 2TB and
the Access time (seek) is slightly lower on
the new drive (lower is better). Normally, all
the 7200 RPM drives cluster pretty close on
Access time (12-16msec or so).

The fastest hard drive I've seen advertised so far,
is a 15K drive (so half the access time) with a
300MB/sec sustained transfer rate. But drives like
that tend to be noisy, so you wouldn't like it.
There was one of those 15K drives that made a screeching
sound, and the claim was, "that was normal".

The fastest solid state drive, is one of the NVMe ones
which works at 2500MB/sec. To boot from those requires
BIOS support, so just buying an adapter card to fit
one isn't enough. They can work as a data drive without
a problem, but if you want a boot OS on it, the BIOS
needs a read routine to boot from it. I don't know when,
if ever, I'll get one of those.

The wiring on those goes at close to 4000MB/sec, but
the chipset buffers hold them back a bit.

And being Windows, of course you don't get the feeling
of speed that you should.

You could get an SSD with 400MB/sec transfer speed for
around $22, and it might be just big enough to install
Windows 7 on it. But it wouldn't have the space to hold
any backups. That's a SATA SSD in a 2.5" formfactor.
