A size comparison of the GPVE and the Hyperdrive HD80. The GPVE is leaning against its cover. I copied the same 1GB CF card to both devices. The GPVE took 21 seconds just to turn on, then 3 minutes, 17 seconds to copy the card. The HD80 turned on and copied the card in 2 minutes, 23 seconds. If you use the GPVE to copy more than one card, the start up time begins to fade into irrelevance, but the HD80 remains marginally faster by almost a minute even without taking the start up time into account.
