lifedrive instead of using conventional flash/SD cards, which are available
in 4GB and psooibly 8Gb flavours. Advantage of cards is that they can be
replaced easily giving additional storage space, small and compact,
Microdrives are mechanical thus suffer from comparitively high current
drain, data latency, fragility, wear and tear on bearings and several other
drawbacks, so I'm assuming there must be some justification/logic for using
"Give a man fire and he'll be warm for an evening.
Set him on fire and he'll be warm for the rest of his life"
Re: Question about lifedrive - microdrive v SD/flash memory
I doubt that 4Gb flash cards were available when Palm took the design
decisions, and there was a lot of suggestion at the time that
microdrives may go up to 20G.
On top of which flash memory has only a limited number of write cycles,
very much smaller than a disk (Although these days it is pretty good).
Figures quoted go from 10,000 to 100,000 cycles which is quite a lot if
you want to store pictures and make relatively few changes to a card,
but not that many if (for example) you are updating files from a 1
It was a design decision, and like all design decisions was a trade-off
between things that will always in the end bite you in the bum. Its
just a matter of deciding on which side you would prefer to get bitten
There was a lot of criticism of one of the T mdoels for using flash
exclusively, rather than having RAM, so maybe this was reaction to
adverse publicity. Only the designer knows.
