Addendum:  if you're looking for speed with an external drive, then you'll want Firewire 800 or eSATA (fastest of all at this point).

Hi Larry-

Interesting test. Some things to keep in mind, however:

Flash drives are quite a bit more expensive than ordinary hard drives. If 
you're recording large amounts of data, a hard drive generally makes more 
sense.

Flash drives are slower than most hard drives, so if your rearming time 
limitations come from mainly from the disk write time, a flash drive is 
likely to make things worse.

Flash drives have limited write cycles. Unless you are using an application 
specifically designed to run from flash, it may well destroy the memory in 
short order. If you want your data on flash, you should explore running 
Sentinel from the hard drive and configuring it to just write the video to 
flash.

Fast, 1TB hard drives are down around $100 these days, and just a little 
more for external drives you can plug into USB. It would take 500 of your 
2GB flash drives to get this storage!
