Unless your entire data set fits in memory, in order to fully drive the data processing capacity of Vector, you must have multiple drives working in parallel. The way to do this is by using striping across multiple drives through RAID (Redundant Array of Inexpensive/Independent Disks) volumes. Use a large stripe size of 512 KB or multiples of 512 KB in order to optimize I/Os sent by the OS down to disk.

Hardware controllers have a limited throughput capacity that may limit the I/O throughput below the level you need for Vector. Therefore, consider software-based RAID with multiple non-RAID controllers to avoid a bottleneck at a single hardware RAID controller if many fast drives are included in the RAID configuration (e.g. more than 8 SSDs).

Also consider choosing a RAID configuration that protects against a drive failure (unless you use a different approach to achieve high availability); RAID5 or RAID6 setups are typical RAID configurations that provide a good trade-off between storage overhead, performance and availability.
