| What are the benefits of supporting Spread Spectrum Clocking (SSC)? | Mar-02-10 |
| Spread Spectrum Clocking is a way to lower electromagnetic interference or EMI. This is important for storage solutions that are required to pass FCC and other agency certifications. All current Serial ATA disk drives implement SSC (some allow you to turn this feature on/off). However, some older SATA drives do not implement SSC. All Sonnet Serial ATA host adapter cards support SSC but will also work with disk drives that do not. |

| What kind of performance can I expect from a using a Sonnet Tempo SATA Card in a PCI slot (like in a Power Mac G4)? | Oct-12-09 |
| 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. |

| Drive(s) connected to the Tempo-X SATA 4+4 occasionally do not appear when the computer is booted or an error message regarding the RAID array connected to the Tempo-X SATA 4+4 is occasionally displayed at boot up, and the RAID array cannot be used. | May-07-09 |

| With a Tempo-X SATA host controller installed and drives connected, the computer locks up and will not respond to keyboard or mouse input, and must be forced to power off (press and hold the power button for more than 5 seconds) then restarted. | May-07-09 |

| Multiple Hitachi hard drives connected to a Tempo-X SATA host controller are not always detected (won't mount). | May-07-09 |
| Affects: Hitachi 7K80, some T7K250, and 7K500 SATA hard drives switched to operate at 3.0 Gb/s when used with a Tempo-X SATA 4+4, Tempo-X eSATA 4+4, or Tempo-X eSATA 8 host controller card using the Marvell 88SX5081 chip.
This condition occurs when the listed Hitachi drives were first connected to a PC and switched to the 3.0 Gb/s data transfer setting using Hitachi's Feature Tool software; these drives originally shipped with the 1.5 Gb/s setting enabled. When connected to Tempo-X cards using the Marvell 88SX5081 chip (which supports 1.5 Gb/s transfers) the drives are not detected properly. Because these particular Tempo-X cards only support 1.5 Gb/s transfers, there is no benefit to switching the drives to the 3.0 Gb/s transfer setting. If you are unsure which Marvell chip is used on your Tempo-X card, you may check your Macintosh System Profile; when you select the installed Serial ATA card, the Device ID will show either "0x6081" or "0x5081".
Note: This DOES NOT affect the Hitachi 7K250 or 7K400 models that do not have the ability to support 3.0 Gb/s transfer nor does it affect Tempo-X eSATA 4+4 and Tempo-X eSATA 8 cards using the Marvell 88SX6081 chip.
To correct this issue, switch the drives back to the original 1.5 Gb/s setting using Hitachi's Feature Tool software. |
