Ok,


Assuming you spend $5 per tape for 60 minutes of SD footage right now.

140 tapes = 140 hours of footage = roughly $700

4 GB p2=$700 = 20 minutes of SD footage at each 4 GB fillup = 3 fillups to equal one tape


so.... fillup and dump out your 4GB p2 420 times and you will equal your tape cost

you will also save roughly 4.6 days of real time capturing assuming it takes 4 minutes to unload a 4 GB p2


not so bad when you look at it this way


:laugh: :shocked: :evil:

That all depends what you're "dumping" your footage to.
You need to factor in your archiving costs... whether it be hard drives, DLT, DVD, or (heaven forbid) tape.

Granted, to be fair you should also put a dollar value on your time (time saved as well as time spent archiving).

4 minutes would be a long, long time to offload -- depends on what you're offloading to. The P2 Store takes 1 minute to offload 1 gig, but it's not a particularly fast device. It's theoretically possible to offload a 4gb card in as little as 50 seconds, provided your hard disks can handle an 80-megabyte-per-second transfer rate!
 
I wonder why they didn't go for the fastest possible transfer rate on the P2 store.
Seems like if you're going to have a dedicated device you would want it to move as fast as possible.

50 seconds for 4Gb, that's more like it!
 
Well, keep in mind it'd take a RAID to support that! 80 megabytes per second is well beyond the transfer rates of most desktop devices, but a 2-drive SATA raid could probably handle that. Set up your desktop with a $2000 Medea VideoRait RT3, with 800 gigs of storage and 125 megabytes/second transfer rate, and you should be quaffing P2 cards like Horsefilms quaffs beers!

The P2 Store uses a laptop drive in it, and 15 megabytes per second sustained transfer rate is probably as much as you can expect from a single laptop drive.
