Cheap and Reliable RAID 5 Storage Compared
 

It is worth mentioning that the controllers from HighPoint and Promise showed no notable weaknesses in comparison with the three well known brands, despite their considerably lower price. Their performance was a good average. Only in the Winbench application benchmark did we see the RocketRAID 1640 fall behind as a result of its lack of XOR processor. Promise provides the option of fitting between 16 and 256 MB of cache memory in its controller. Reusing memory that might be lying idle in a drawer is a sensible and cost-effective approach
