Looking for a eSATA to Firewire converter?

[markw10]

I am buying an external Blu-Ray drive and have been looking at one by OWC that has USB 2.0, Firewire 400, 800, and eSATA connectors. I've really become interested in a drive that is made by Buffalo Technologies and has a USB 2.0 and eSATA connector. The issues are as follows:

-Will USB 2.0 handle the bandwith well or do I really need something such as Firewire or eSATA?

-Most of all, is there an adapter to convert an eSATA connector such as on the Blu-Ray drive to a Firewire connector that I could plug in the front of my Mac Pro?

Here are the read speed specs for various Bluray drives...

1× @ 36 Mbit/s (4.5 MByte/s)
2× @ 72 Mbit/s (9 MByte/s)
4× @ 144 Mbit/s (18 MByte/s)
6× @ 216 Mbit/s[1] (27 MByte/s)
8× @ 288 Mbit/s (36 MByte/s)
12× @ 432 Mbit/s (54 MByte/s)

USB2 can easily handle up to 8x... it would be a tough call at 12x. USB2 raw data rates are up to 480Mbps with 320Mbps being a practical limit.

Unless you are buying a 12x drive and plan to saturate it with data continuously, I can't imagine that eSata has any advantage over USB2 in this application.

Thanks. That's all I needed to know. I will look out for something with USB 2.0.
