Installation and Testing
Physically installing the Rocket Raid card was no
more difficult than any other PCI expansion card. It's size is no larger than
any typical sound card, and there are no bulky connectors to block other PCI
slots. With the smart location of the connectors on the top edge of the card,
connecting or disconnecting the SATA cables will not require the card to be
removed from its slot. Moving on to the BIOS settings, I found it
necessary to change the USB Keyboard and Mouse support in my motherboard BIOS
from BIOS to OS in order for the Control-H command to let me into the RAID cards
BIOS. Once that was done, I was able to complete the software portion of the
RAID 0 array.
Each option of the BIOS
is numbered in the order the step will be performed. From the main menu we
choose, Create Array. This takes us to the menu where we will select the (1)
Type of Array [Raid 0] (2) Name of the array (3) Select which disk drives
will be included in the array (4) The block size of the array [16K] and then
lastly (5) Start Creation Process. After those steps are complete, you should
never need to enter the BIOS of the Rocket Raid again, unless something go
drastically wrong. If in the unlikely event you do have serious problems with
your array, the printed users manual contains detailed instructions which will
guide you through a re-creation/repair process.
The testing process will
involve benchmark tests with Drive-Tach and SiSoft Sandra. The drives tested
will be two Western Digital WD800JB 80 Megabyte '8 megabyte cache' drives
configured in RAID 0 with 16 kilobyte cluster sizes using the Rocket Head 100
adapters. Windows XP Professional on an ABIT
NF7-S running at stock speeds of: PCI 33MHZ, Front Side Bus 166MHZ and Overall processor
2075MHZ. 1 Gig of Corsair XMS3200C2 running on a 166MHZ memory bus.

The Rocket RAID
controller scores higher in the Sandra test than the other reference IDE RAID systems. The
use of the Rocket Head adapters really helps keep cost down and makes migration to
this system much more affordable. Until the internal technology of ATA drives
improves the transfer
rates and seek times, scores of even the Serial
ATA drives will not increase dramatically over the parallel ATA units.

Drive Tach
shows the arrays read performance in relation to the position on the disk. In
the beginning of the array (at 0 Gigs) read performance is at its highest at
over 54000 kilobits per second. The tail end of the array (at 150Gigs) obviously
has the worst performance at just over 32,000 kilobits per second. The average
of 47652 kilobits per second also takes into affect the very large dips in
performance. CPU utilization of 28.7 is rather high but can be attributed to the
very small cluster sizes defined in the array.
