Default Old Laptop Speeds

My old laptop has USB2 ports.
It also has MM slots which are now empty.

Is there a MM card that adapts to USB3 ?

Most important, does using such a MM card get the data transfer speed up
to or near USB3 speed ?

Since you don't mention a USB 3 port then you don't have USB3 support.
Pushing a faster MMC (not MM) card into the slot is not going to make
the slot faster. Need a new laptop. Won't help speed up an MMC card,
though; see:

https://en.wikipedia.org/wiki/Compar...hnical_details

MMC: max read speed = 2 MB/s (16 Mbps), max write speed = 2 MB/s (16
Mbps)
USB 2.x: max speed = 60 MB/s (480 Mbps)

The USB2 controller to which the card slot is connected is far faster
than any MMC card you can slide into the slot. Not until you get a
flash card that exceeds 60 MB/s (480 Mbps) would the slot support a card
capable of USB3 speeds, and no MMC card is that fast (the eMMC is BGA
soldered, so it is not user-removable media).

What kind of slots ???

Does your laptop have a make and model number ?

The slots could be for a PCCard or for an ExpressCard.

A number of variants exist.

https://en.wikipedia.org/wiki/PC_Card

https://en.wikipedia.org/wiki/ExpressCard

Expect the pickings to be "slim picking".

A PCCard type solution, needs a USB3 chip
plus a bridge chip. And could cost $100 once
a bit of profit is factored in. Plus, it
won't go all that fast.

The ExpressCard is a more natural fit, only
in the sense that a bridge chip isn't needed.
USB3 chips are generally PCI Express devices,
and the ExpressCard has that as one option.
The speed should be better than a PCCard
solution.

But don't expect to beat your buddies when
benchmarking. The results of this experiment
will be "faster than USB2", but depending on
your budget, may not be worth it.

The single best interface on my old laptop,
is the GbE NIC. If it wasn't for that, I'd
have probably tossed the laptop in the trash.
As the USB2 ports are too slow to tolerate.
The gigabit ethernet allows me to do backups
at a decent speed that doesn't cause hair loss.
