This seems consistent with other RAID controllers. AOpen AK77 ProA Promise RAID for a 32K stripe size. This gives a slightly better write performance at the expense of read performance. How about a 64K stripe size? We can see that 16K is the best stripe set we can confirm this with many more tests but we'll spare our readers the gory details and we will stick with this. We no longer have access to 4 identical drives so took a trip to a data center nearby name withheld to avoid getting our friends in trouble where a server using a 4-disk RAID0 array on an SX was in operation. We couldn't run HD-Tach as this requires non-partitioned drives but ran some other benchmarks. Performance with 4 drives was superb with sustained rates averaging about 3 times that of the single drive graph above. RAID5 performance was also excellent and the parity overhead was barely noticeable with the card in AOpen AK77 ProA Promise RAID bit PCI slot.

Conclusion Eventually this card has shown us why Promise engineers have so much faith in it.

These basic rules stipulate that performance is limited to N times the speed of the slowest drive and total size is limited to N times the capacity of the smallest drive where N is the number of drives in the array. In practice these are theoretical maximums that may be limited by other factors. Here are the 4 drives we managed to pull together showing the ease of connectivity to the card: There's hardly any clutter of cables even with 4 drives.

Serial cables plug easily and securely into the card without blocking airflow. The above picture clearly illustrates how little space is taken up by the connectors of S-ATA drives.
