Allows installation of up to four additional Serial ATA drives within a G5. Also allows for attachment of four external SATA drives. When the original two drives within a G5 are included, the user may attach up to TEN! drives to his/her G5. Includes new air baffle mounting plate for G5, drives, 4+4 port SATA PCI host card (slot required), SATA and power splitter cables. It is constructed from mirror aluminum and also serves as an extraordinary heat sink for the two additional drives, which are mounted to the new air baffle. When these drives are RAIDed under OSX, resulting performance exceeds 500MB/sec (not a misprint -- 500MB!) and is suitable for support of uncompressed1080i 10bit editing under Final Cut Pro. It is the fastest internal storage solution available for the G5 .
