Ladies and Gentlemen;
Hot off the presses. Just got access to some larger SATA drives for Benchmarking.
I have access to several new larger Drives. A Seagate 250 - 7200 rpm ST9250410AS, WD 320 - 5400 rpm WD3200BEVT, Fujitsu 500 - 5400 rpm MJA2500BH, and a WD 640 - 5400 rpm WD6400BEVT.
Fortunately, I have a second adapter so I can start the process.
Why start small, I grabbed the new WD 640 GB SATA drive and stuffed it in the drive caddy.
Stuck it in my MK3-J model and fired it up to Bios.
Attached is the screenshot of this.

Yup, it took it. Found the WD 640 GB HD
Where will the benchmark top out then, Azrials "kidding" about a 1TB, maybe.
