Hi Daniel
Thanks for this point.
- Do you consider a streaming HDD that has to parse Audio/Video data
should set the Read ahead flag ? (I understand yes)
- Is this Read ahead flag still valid if the streaming bit is set (ATA6
on "A/V" HDD) ?
Thanks

Hale,
I have always thought that the reason to turn read look ahead off was to
increase read cache performance. If there is an application that
frequently
re-reads recently read data then you want the largest possible read cache.
By
turning read look ahead off the drive can devote more cache to keeping
previously
read data instead of using the buffer to store read ahead data.
