42 minutes for 64Gigs of data?

Transfering 2 32 GB Cards at the same time.

I have a Sonnet Qio on loan. I have a MacBook Pro 2.4Ghz Intel Core 2 Duo 15″.

I have tried different configurations and this is what I experienced.

I have 2 eSATA Hard drives hooked up to the Qio. I have 2 R-Series 32 GB P2 cards in the Qio.

If you transfer 2 P2 Cards at the same time to different Drives, or even the same drive roughly 42 min to transfer both cards. Had a look at the Data transfer speed. A single card gets transfered at 23 MB/s., 22min., As soon as 2 Cards are transferring, it drops down to 10 MB/s., 42 min.

Tried something else. Hooking a FW800 to the Laptop and 1 eSATA drive to the Qio, same deal.

This doesn’t make any sense because on the Sonnte Qio page, read perforamnce for 2 P2 cards is speced at 50 MB/s. One card is speced at 25 MB/s, which I came close to, and 2 cards speced at 50 MB/s, I only saw 10 MB/s. Go figure???

I don’t know if the E-Series of P2 cards will behave differently. I don’t have access to E-Series Cards.

In comparison the Duel Adapter transfers a R-Series 32 GB card in 18 min. Deul Adapter with a FW800 Drive. Transfer speed, hold onto your hat is, 32 MB/s. Guess what I am sticking to. Sad to say, Duel is king. The cash ain’t worth it.
