How many drives of what type are supported in the Power Mac G5? Are there third-party products to use more drives than are "officially" supported?

Officially, all models in the Power Macintosh G5 series, regardless of architectural differences, support only two 1.5 Gb/s Serial ATA (SATA) hard drives.

Fortunately, there are a variety of third-party products that make it possible to add additional internal 1.5 Gb/s SATA drives to the Power Macintosh G5.

One such product is the Sonnet G5 Jive, which makes it possible to add three more internal drives to Power Macintosh G5 models with PCI-X or PCI-Express slots when installed along with a Serial ATA host adapter card.

Sonnet notes that the Jive:

Consists of a custom metal base plate and mounting bracket, mounting screws, three internal SATA data cables, and a custom-designed 3-drive SATA power cable. It mounts in the space at the bottom of the case beneath the optical drive, and its installation has zero impact on PCI slots and adapter cards.

Sonnet also mentions that the G5 Jive places these additional drives in front of the CPU fans and as a result "there will be times when these fans will spin faster; it is normal and depends on system activity. Our testing indicates the G5 has plenty of cooling capacity and will run just fine."

If you choose to install more drives in the Power Mac G5 than are officially supported by Apple, you should carefully monitor the temperature of your system to ensure proper operation.
