available with RAID 50. For example, on a 12-port controller, you can have a grouping of 3, 4, or 6 drives. A grouping of 3 means that the RAID 5 arrays used have 3 disks each; four of these 3-drive RAID 5 arrays are striped together to form the 12-drive RAID 50 array. In addition, RAID 50 arrays - 3Ware 9550SXU-16ML | User Guide - Page 18
configurations available to you are determined by the number of ports on your controller, and the number of drives attached to those ports. You can configure all drives in one unit, or you can configure multiple units, if you have enough drives. 8 3ware 9550SX Serial ATA RAID Controller User Guide - 3Ware 9550SXU-16ML | User Guide - Page 19
For example, with 12 drives, possible RAID 50 configurations include 2 subunits of 6, 3 subunits of 4, or 4 subunits of 3. With 10 drives, a RAID 50 will contain 2 subunits of 5 drives each. With 16 drives, a RAID 50 will contain 2 manufacturers are more likely to be able to be used www.3ware.com 9 - 3Ware 9550SXU-16ML | User Guide - Page 20

Note: Striping size is not applicable for RAID 1, because it is a mirrored unit without striping. In general, use smaller stripe sizes for sequential access (such as video access) and larger stripe sizes for random access (such as a database). 22 3ware 9550SX Serial ATA RAID Controller User Guide - 3Ware 9550SXU-16ML | User Guide - Page 33
