For those with a 5 card P2 reader, or considering getting one, I had the chance to benchmark Panasonic's older PCD20 reader vs the newer PCD35. All I can say is: what a difference, the PCD35 is well worth it if you do a lot of P2 offloading!!
The PCD20 can connect to your computer via a USB2 or FW800 connection, but for some reason, produces roughly the same transfer times regardless of the interface you use (at least on the Mac, and a Panasonic rep also confirmed this with me). But the PCD35 attaches via a PCIe card, which gives it far faster transfer rates---about 5 times as fast as the PCD20.
Here are some benchmarks transferring the same full 32GB E series card to a Sonnet 8 drive SAS Raid (using an ATTO r380 card for the raid hookup), a 2 drive RAID 0, and a FireWire 800 hard drive on the Mac. All tests using Shotput 2.02 (beta):
PCD20 via USB2 to SAS RAID = 21.1 minutes (1266 seconds)
PCD20 via FW800 to SAS RAID = 19.4 minutes (1163 seconds)
PCD20 via USB2 to a Firewire 800 hard drive (instead of the SAS RAID) = 28.1 minutes (1688 secs).
PCD35 via PCIe cable to SAS RAID = 4 minutes (240 seconds)
PCD35 via PCIe cable to a 2 drive RAID 0 (made in Disk Utility): 5.1 minutes
Wow! As you can see, the PCD35 is about 5 times as fast as the PCD20 in copying a single 32GB card. Imagine the time savings when transferring 5 full 64GB cards at the end of the day! A prelim test I did with 5 full 32GB E series cards had the transfer taking less than 30 minutes for all 5 cards!
The PCD35 is only about $200 more expensive than the PCD20. The only drawback is that you have to use up a PCIe slot in your computer to accommodate the reader's interface card. Also, Panasonic doesn't sell a laptop connector for the PCD35, but a rep told me that you might be able to use the Matrox MXO2's connector card, since it uses the same cable as the PCD35.
Anyway, if your main machine is a desktop machine, I would heartily recommend the PCD35....
