Benches on popular forums show it to have around 38-39 MB/s average
sustained read and 0.39ms access time.

Heavily dependant on the controller device, however.
Benches on Windows Boot shows that it reduces the boot time by about
40%.


It's nowhere NEAR the Gigabyte iRAM, however, which has the record at
'to desktop' in 3 seconds:

$120 for the drive, plus you gotta buy memory for it. 4 GB max.

Alternatives include the 8/16 GB Hyperdrive4, but it's $780/$1060 for
the 8/16 GB models, WITHOUT memory.

"Pros: Excellent Speeds! HDTach 3 290 MB/s Burst, 265 MB/s, 0.1 ms Seek Times...WOW! "

Wow indeed, from a card with only a ~120MB/s interface.

I don't believe a reasonably fully functional Windows setup could boot
up in 3 seconds, regardless of the speed of the storage device. Only
*some* of bootup time is dependent on the drive. Much of the bootup
time is initializing other hardware devices, the network, running
services (which take CPU as well as disk reads), logging the system in
to a Windows domain, etc etc.
