I have an AJ-PCD2G USB2 single-slot P2 card reader. It has served me well enough. I just got a new iMac 27" and plan to re-purpose my older Mac Pro as another editing workstation. The AJ-PCD2G P2 card reader can stay with it but I want another P2 card reader to use with my new iMac (2 TB, 4 USB3 ports.) What are you guys using to offload P2 cards as fast as possible?
I know the AJ-PCD30PJ exists but its price tag is too steep (~$2,200 new/~$1,400 used.) The Sonnet Technologies Qio-TB looks interesting since it comes with a Thunderbolt adapter and it's price tag (~$895) is more reasonable but is it any good? There aren't many reviews out there from P2 users and Helmut Kobler's early review (2yrs ago) mentioned it transferring P2 card data a lot slower than SxS, compact flash, etc. One thing that concerns me is that I only have 2 TB ports and this Qio-TB device doesn't seem to give the user any daisy chain connectivity.
Looking through older Cow forums, it seems that a fast (USB3 or above) P2 card reader at a reasonable price has always been something Panasonic has failed to manufacture. I see they have now begun manufacturing a new single-slot, USB3, micro-P2 card reader (AJ-MPD1G) at a price I would pay ($335) but I don't use micro-P2 and don't plan to any time soon. I have various full-size P2 cards (32GB & 64GB) and for now, they serve my storage capacity needs. It seems that Panasonic has finally started to address a market need (low-cost, 2-slot P2 USB3 reader) but have skipped over existing P2 customers in favor of newer technology (micro-P2) that will still take a little while for users to migrate to.
