The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. Designed to emulate the behavior of an actual application, NASPT uses a set of real world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation and more provide a broad range of different application behaviors.
- RAID Level Description
JBOD: Combine multiple drives and capacities into one drive.
RAID 0: Normally used to increase performance and useful for setups such as large read-only NFS servers where mounting many disks is time-consuming or impossible and redundancy is irrelevant.
RAID 1: Create an exact copy (or mirror) of a set of data on two or more disks. This is useful when read performance or reliability are more important than data storage capacity.
RAID 5: Use block-level striping with parity data distributed across all member disks.
RAID 6: Extend RAID 5 by adding an additional parity block; thus it uses block-level striping with two parity blocks distributed across all member disks.
RAID 10: A Stripe of Mirrors. Multiple RAID 1 mirrors are created and a RAID 0 stripe is created over these.
RAID 50: Combines the straight block-level striping of RAID 0 with the distributed parity of RAID 5.
RAID 60: Combines the straight block-level striping of RAID 0 with the distributed double parity of RAID 6.
