One point that a colleague brought up that hasn't been covered here is the relative desirability of many small cheap cards versus one big expensive card - same total memory. For a small or one man operation, if the cost/GB is the same between the two options, there may be little in it, but for a large organisation the "many cheap" option potentially has big attractions. Regarding transfer speeds, a little searching has thrown up this thread: http://www.dvinfo.net/conf/showthread.php?t=67007 , and posts 3 and 4 may be of interest in this context. In the former Barry Green states that: "If you plug straight into a USB 2 port you should get transfer speeds of around 1GB per minute." and in the latter David Tames gives some practical comparisons, with a P2 store here taking no less than 6min 24sec to transfer a full 4GB card!!! (A full 4GB card only appears to be about 3.51GB?) I'm interested what kind of system Jeff Kilgroe is using if he is consistently achieving far faster times than this, especially if he is achieving 4x? |

"THE RESULTS: 1 straight 10 min clip shot at 720P 24pn recorded to 4 gig P2 card Card copied to P2 store (approx. 4 min.) P2 store connected to G5 USB 2.0. P2 "no name" Imported straight into FCP. TIME 5 Min. 39 Sec. THIS IS GREAT AND ACCEPTABLE However, same P2 "no name" copied to a new folder on G5 24 Min. SAME USB Cable, SAME EVERYTHING!" http://www.dvinfo.net/conf/showthread.php?t=67592 what we need to see is the transfer speed of the p2 port on the panasonic toughbook... got any numbers on that?

if i had a p2 camera i'd be using it with the firestore, i wouldn't buy any extra p2 cards at all. |

It's obviously only useful at all for material I edit myself. When rushes have to be given away, tape takes a lot of beating. Thats what so appeals to me about Infinity. A cheap archive medium and a more transient solid state "NLE medium" running in parallel - just like the Firestore and tape - but no extra boxes and cables. Fantastic. |

A MonarchComputer Hornet Pro SFF AMD X2 4800+ Dual Core CPU 2GB RAM nVidia 7800GTX 512MB 2 * WD Raptor 10Krpm HDDs in a RAID-0 stripe Operating with WinXP Pro SP2 and all current updates Spec-Comm PCI to PCMCIA adapter Connected to our LAN via its primary gigabit ethernet port. Speed is most definitely limited by the speed of the P2 card itself and by the gigabit ethernet port (which is theoretically 10X faster than DVCPROHD anyway). Our primary storage is a fiber backbone SAN, but that's a non-issue at ths point as I can ingest at 4x or so on this system to its local drives

In re-reading this discussion it strikes me that the extra potential transfer speed of P2 can be relevant at the editing end even if it's not necessary at the recording end, so maybe P2 isn't rendered obsolete by advances in standard flash memory after all. I still think more people would be interested in an IT workflow using inexpensive media than P2, and it will be interesting to see what Panasonic (and others) do in the future using AVCHD discs and so on. These are interesting times in terms of equipment options, and hopefully we'll see even more new options in the future.

For the reasons given above, I feel P2 is more likely to carry on in expensive pro cameras than in the prosumer market such as for the HVX. Theoretically, even higher end users could get speed benefits at download (if their systems are capable) by techniques such as downloading 4 CF/SD cards in parallel - so 4 8GB CF cards could be downloaded in the same time as 1 32GB P2 card. say. Practically, I suspect the biggest threat to P2 comes from the architecture upon which it is centred currently being phased out. Increasingly, laptop computers may have inbuilt CF slots, but need an external reader for a P2 card. |
