JayC commented that flash is a viable option. I think this is interesting.
At CostCo I can buy two (2) 2 GB SD cards for $27. If this trend continues, I could by two (2) 4 GB SD cards for $30 in 12 months. It might be interesting if you could do the same with a 32GB that sells for $130 plus.
This makes sense for short videos, not videos of longer events, but if your kid is singing 2-3 songs in show, this works well. Videos up to 5-10 minutes at a NTSC or slightly better resolution.
As long as SD can keep up with the read/write speeds then this might be viable. The issues for SD memory is speed and cost. SD makers can speed up the rate for read/write by putting more banks in parallel. However, this adds cost.
Can the flash keep up with the needs of pro-sumers? Can it keep up with HD video Camcorders?
How do the read/write speeds of flash compare to rotating media like hard drives?
Wikipedia http://en.wikipedia.org/wiki/Secure_digital says:
The first column is rating, the second is speed. I’m pretty sure that SATA is faster, and that hard drives are faster. SD may have a power advantage. I know that SSD drives do. However, the 64GB drives are something like $500. So an SSD with SATA in a camcorder makes more sense to me from a speed perspective.
If you know something about this, please post a comment.
Also, let us know what you think the first products will be?
I’ll respond to Mick’s incendiary comments another day. He’s always drawing to draw attention to SATA for some reason.
