RAID Performance with ATTO
To start off with our testing of the Areca 1883i, we loaded up the RAID card with eight Seagate Enterprise Capacity v4 12 Gb/s SAS hard drives.
In the chart above, we have our results for RAID 0 starting with two drives all the way up to eight drives. Two drives were able to reach 425 MB/s read and 440 MB/s write. Moving to four drives, we peaked at 820 MB/s read and 850 MB/s write, and lastly eight drives topped out around 1700 MB/s read and 1800 MB/s write.
Swapping over to RAID 5 and 6 with both four and eight drives, we start with our results of the four drives RAID 5 array that ended up topping out at 600 MB/s read and 650 MB/s write. Adding four more drives allowed around 1400 MB/s read and 1400 MB/s write.
Moving over to RAID 6 results start with our four drive array at 400 MB/s read and 400 MB/s write again adding four more drives to our RAID 6 this array topped 1200 MB/s read and write.
Taking things to the next level with the 1883i, we built three more arrays for testing. These include a four drive RAID 10 along with an eight-drive RAID 50 and RAID 60 array.
Starting with the RAID 10 results came in at a touch under 600 MB/s read and a touch over 400 MB/s write. Over to RAID 50, results topped 1200 MB/s read and write, while our RAID 60 hovered around 800 MB/s read and 400 MB/s write.
