The G-SATA follows in the footsteps of G-Technology’s G-RAID 800 ( ). The stylish housing remains unchanged.
The G-SATA requires that you use Apple’s Disk Utility to format the drives. In our testing, when formatted as a RAID 0 volume, the G-SATA had an average read speed of 93 MBps and an impressive 160 MBps write speed when empty, using a Sonnet Tempo 4+4 PCI-X card. At 90 percent capacity, the G-SATA’s read and write speeds fell to 47 MBps and 79 MBps, respectively. This minimum speed ensures that users can edit even 10-bit uncompressed standard definition video without problems.
To give you an idea of how this stacks up to FireWire speeds, the G-RAID 800 turned in read speeds of 76.5 MBps and write speeds of 54 MBps in our review of that drive.
One noteworthy shortcoming of the G-SATA is that it does not have hot-swappable drives, so you can’t easily replace drives.
In standard operation, the G-SATA’s fan was relatively quiet compared with those of the other RAIDs we’ve tested recently, and the enclosure always remained cool.

Macworld’s buying advice
The G-Technology G-SATA is a good—if expensive—workhorse, with fast write speeds and quiet operation. Currently, G-Technology is neither bundling the G-SATA with SATA host adapters nor selling SATA cards (though the company plans to in the future). In the meantime, anyone interested in the G-SATA should look to Sonnet or FirmTek for compatible host cards.
