dellock6 wrote:For stripe size, you should align it to the expected deduplication level you are willing to use:
128k for "wan" (256k original, 128k with compression on)
256k for "lan" (512k original, 256k compressed)
512k for "local" (1024k original, 512k compressed).
Also, you should use the same size for both the storage and the file system, or you can incur in write amplification problems. So, use the same value also for NTFS. On Windows 2008 and later ntfs is automatically aligned to the underlying disk, otherwise you should also check and fix alignment problem, this is usually an uderestimated problem in storage configurations but it can lead to serious performance penalties.
