PCMCIA Hard Disk Drives?

almost thru-put doesn’t make it …

Donatello,

[donatello] ” thru-put doesn’t make it …”

What? “66.7MB/s” is over 5 times the necessary thu-put of 100Mb/s. The P2 cards are only a bit faster at 80MB/s. You’ve mixed up bytes and bits.

They lack the necessary LSI that understands and directs traffic in MXF.

All good things come with time.

Hmm, in Toshiba’s specs it is said that in “PC Card Memory mode” transfer rate is 20MB/s (=160Mbps)…

[Ron Shook]

Donatello,

I probably owe you an apology after thinking about this for awhile. That 67MB/s figure is probably some sort of buss speed as I can’t believe that this tiny 4k rotational speed drive is that capable. I wonder how capable it actually is in real life?

I wonder whether that time has anything to do with my time? (g)

Thanks,

I don’t want a hard drive anywhere near my camera – solid state is how we need to be thinking. P2 is probably the best thing the HVX has going for it at this point.

This is interesting statement since you can not record that much video on those cards.
Where you going to transfer that footage from P2 cards? Even Panasonic is offering you P2 Store (Hard Disk Drive)
Unless you go directly to AJ-HD1200A tape deck you will have to transfer to hard disk at some point. There will be Blu-Ray soon and other technology to archive footage rather than hard disk.
This is completely different workflow but now hard disks are pretty much unavoidable and cheapest way to go.

Hi Mariuz,

The way the guys, that did the demo footage in Las Vegas and LA, worked was with just 2 P2 cards from Thursday till Saturday, when I finally showed up with more. All they did was while one card was recoding, the other was transferred to the Hard Drive via the computer and using that old standby software called Windows Explorer. The DP said he was never waiting for a card to record onto. The cards transfer faster than you can fill them, esp. in 720P/24PN. It is just as viable of a work-flow as the P2 store, but cheaper since you may alread own a laptop computer and a hard drive, although not as small of a package. 😉

Best,

Jan

Jan,

[Jan Crittenden Livingston] “They lack the necessary LSI that understands and directs traffic in MXF.”

A couple of dumb questions for ya:

An “LSI” is some sort of custom circuit or chip?

Is it that these PCMCIA hard disk drives are impossible for the HVX to record to if properly preformatted, or that without this LSI it is possible to record linearly, but only in a write once fashion, not allowing you to, for instance, nuke the last take or other non-linear features?

Thanks again,

Ron Shook
