Drive performances are not made equal - a few speed test comparisons

Some are abysmal! Like this Patriot USB 2.0 32GB flash drive:

Seriously flawed!

Compared to this no name USB 2.0 16GB flash drive:

Useless for most tasks.

Obviously pale in comparison to this (meh!) WD My Passport for Mac USB 3.0 1TB portable hard drive:

That's acceptable for HD work, certainly not fast.

What's a bit better is this WD Red 2TB 3.5 bare hard drive in a USB 3.0 (or eSata dock, or on the internal Sata bus):

Acceptable, OK fast for most HD work.

This G-Drive 4TB USB 3.0 beats it by another a small margin:

Acceptable, OK fast for most HD work.

The old CalDigit 5 hard drives Raid0 4.7TB via eSata is still faster though:

OK fast for most things HD (but NOISY! as in LOUD FAN NOISE)
