RAID Lite Performance
RAID Lite has been found to provide leading edge performance. The results of
ANDATACO's extensive benchmark testing have been summarized in the tables below. For further information regarding I/O performance, please refer to the RAID Lite Application Notes document. (Also presented in ANDATACO's RAID section on the World Wide Web.)
- RAID Lite achieved its best performance overall using RAID levels 5 and 6. RAID level 6 provides the best overall performance and availability since it utilizes striping without parity and every drive is redundant (mirrored). RAID 5 offers comparable performance with a high level of fault tolerance but lower cost.
- RAID Lite provides at least 5 to 11 times the write performance over the GigaRAID/xS. Four times the performance over GigaRAID/xS is achieved with sequential reads while random reads perform 3 times better.
- In most cases, Veritas VxVM offers better random read performance but RAID Lite offers better sequential write performance overall and better random write performance using RAID 5.
The following table notes the highest transfer rates obtained by RAID level. A brief description of the RAID levels have also been included for your convenience.

Again, we see that we achieve the best performance overall using RAID level 6 due to its striping without parity coupled with mirroring.
