Promise FastTrak100 TX4 Ultra ATA/100 RAID Controller - RAID0+1 (Striped Mirroring)

Read also:

This is a soap-box of the Promise FastTrak100 TX4, i.e. the configuration where all its advantages must be revealed. Plus, hot replacement of discs (of course, with the help of SuperSwap). Well, let's see how the TX4 will perform.

Ziff-Davis WinBench

Unfortunately, there is no any increase in the linear speed...

as well as the decrease in an access time...

Well, at last, the gap is considerable! Just for comparison here are the diagrams for an array of two discs

The relative gain ((max. value - min. value)/min. value) in the High-End WinBench test in the FAT32 for RAID0 is 0.04, and for RAID0+1 it is 0.17. The gain is 4 times more.

Intel IOMeter

Well, a significant benefit from the 66 MHz bus is still lacking.

The streaming read mode doesn't do favor for the TX4. It is BIOS to blame? But in the recording mode the results of the TX4 grow up, though the interval between them remains.


The Promise FastTrak100 TX4 benefits from the RAID0+1 as compared with its junior brother. This advantage and hot replacement support (which is lacking in two-channel controllers) let me recommend this controller for such arrays.

Full test results are in the table.
