Intel IDF StripeSize 的敘述
http://www.intel.com/idf/us/fall200...USDSIS05_OS.pdf
引用:
Smaller Stripe Sizes (32K or less)
Better performance for sequential I/O
Better for synthetic benchmarks (Sandra*, HDTach*)
Usage: Video Editing/Streaming
Larger Stripe Sizes (64K and above)
Better performance for non-sequential I/O
Better for application based benchmarks (Winstone*, Sysmark*, Winbench*)
Usage: General desktop applications and games
Use Large Stripe Sizes: 64K+
