Optimum raid 0 stripe size & format block size for windows 7 media center
MB: Gigabyte GA-EX58-UD5 CPU: i7 920 Mem: Corsair TR3X6G1600C8D Dominator 6 GB@1600 HDD: 1 X Seagate 1.5 TB (win7-64 boot drive) & 2 X 2TB Hitachi in RAID0 I want to optimize the raid0 array as storage for Windows Media Center HDTV recordings and for HD video processing (e.g., mpeg-2 -> mpeg-4 transcoding, etc.). What is would be best for the RAID 0 stripe size? (128K is default) What would be optimum for the RAID 0 format block size? Thanks! Last edited by gigabyter; 11-08-2009 at 03:14 AM.

512 KB block size normally will give you your best performance size.

Re: Optimum raid 0 stripe size & format block size for windows 7 media center
RAID 0 is not fault tolerant so do you backups.
Stripe size of 64KB for the RAID controller is best for most users. 128KB is for SQL databases or arrays that have very large files as the majority. You will find the majority of your files on a normal computer are 32-64Kb. In Windows for the format in NTFS, 512 bytes is optimal. This will give your stripe 128 x 512 byte blocks = 64 KB.
