File Name: tempo-x_sata_4+4_qsg.pdf Document Version: QS-TSATA-X44-E-B-011405 File Size: 1.2 MB Installation instructions for installing the Sonnet Tempo-X SATA 4+4 8-Port Serial ATA PCI-X Host Adapter Card into a supported Mac omputer.
Our testing has shown that a four-drive array will sustain maximum reads and writes of about 200 MB/second in a 64bit, 33MHz PCI slot. An eight-drive array will not provide any additional performance beyond that of a four-drive array in that slot. To get significantly more performance, you need to use a machine with a PCI-X slot.
A very small number of Tempo-X SATA 4+4 users have reported a condition in which connected drives installed in an external case intermittently do not appear when their computer is booted.
To address this issue, update the Tempo-X SATA 4+4 card's firmware to version 1.0.1 or later by downloading and running the latest Tempo-X firmware updater.
