P2 cards hold 64GB and cost $1000 usually, cameras hold up to about 5 or 6 of these.

uses SD/SDHC cards. 3D cam is the $21K model.

7 pounds. XLR audio in, HDMI out, USB 2.0, Component Analog out, 6-pin IEEE 1394 for DV only out. 12X optical zoom with Optical Image Stablization, waveform monitor display, focus bar display and enlarged display, auto focus with face detection, zebra functions. 1080 and 720 HD @ 60i, 30p, 24pN as well as 480 SD @ 60i, 30p, 24p. 32GB SDHC memory card can store three hours of 1920x1080 video and audio in PH mode. MPEG-4 AVC/H.264 high profile encoding (doubling of bandwidth, improved video performance over MPEG-2): recordings look clean and crisp during fast motion without image degradation or dropouts.

this kind of tape does not handle many passes over the tape head without a reduction in signal quality, but it is a high quality, 25 or 50-minute format. also requires special tape machines to interface with a Mac or PC, and a similar unit is required for use in production. Apparently the VARICAM is a popular choice for a camera (it can choose frame rates from approx. 1-120fps).

Panasonic P2 Cards: The panasonic P2 card is essentially a 64GB memory PCMCIA/PC Card. I personally see the possibility of having far more bit density with today's memory technology, though it is possible that may be more difficult if you are using Industrial Flash. I don't know what kinds of bit density you get with Industrial Flash, since I know next to nothing about Industrial Flash, except that it is far more reliable than Commercial Flash (the kind sold in most flash drives & SSD's), and that the kind of industrial flash I know of typically lasts 3 years in 24/7 server environments where it is beat to death. that's pretty good. Cameras typically have somewhere around 5 P2 slots.

for use in Panasonic HD VariCAM cameras, and possibly in HD/cinema cameras like the Red One.

red-drive is raid 0 pair of 160GB hard drives that mount on the camera rail (making 320GB). red-ram is a Raid 0 pair of 32GB flash drives (SSD's?) (making 64GB). redflash module is a CF slot and is included with every red one camera.

There is a reader with 5 P2 card slots: it is supposed to work with 8GB cards (but hopefully it will work with larger - wouldn't hurt to ask someone). Obviously, the reason why there are so many is because the average camera/camcorder has about 5 P2 slots, and you go through them rather quickly with HD content.

can't tell from picture how many slots it has. If you are really strapped for cash, this might be the model to go with, although the number of slots may be few. based on PC Card slot, so it is possible you may be able to use with a laptop.
