HighPoint RocketRAID 1740 and RocketRAID 2300 RAID Controllers Reviewhardnrg - January 24, 2008
The following tests were run on Vista 64-bit using a four drive RAID-5 array. Each test was run with a normal RAID-5 array, and with one of the disks disconnected (degraded).
SiSoft Sandra Pro XII:
So the 2300 remains the leader for write performance for RAID 5 arrays compared with the 1740 HighPoint card and Nvidia 680i onboard RAID controller. You can also see both HighPoint cards show a performance advantage for applications when the array is degraded.
