the CardBus interface is even slower than Firewire / USB 2

What for?
The New Flying MacBook Pro; Seatbelts sold Separately!
那Cardbus Type II 界面到底有多慢呢?感恩!
type 1 ok
type2..........................


e04,跟usb1.0差不多
單純從Type II CardBus的throughput來看,

CardBus (32 bit burst mode)
* Byte mode: 33 Mbytes/sec
* Word mode: 66 Mbytes/sec
* DWord mode: 132 Mbytes/sec

從這項產品在網站上公佈的資料來看,

Host Bus:
* 32-bit, 33Mhz
* PCI 2.2 Compliant
* Type II CardBus

Transfer Rate:
* Supports PIO and DMA modes
* Supports bus master
* DMA at 1.5Gbps burst rate

我想從數據上看來,不會比USB 2.0差才對。
