Re: ReadyDrive and ReadyBoost: How to know they are working?
You cannot accesss the contents of the ReadyBoost external device or
ReadyDrive cache. The "Led" on the ReadyBoost device indicates when it is
functioning. ReadyBoost and ReadyDrive are used by Superfetch for
non-sequential read/writes and the HD directly for sequential read/writes. -
which is why performance depends on type of HD activity.
I have no experience directly with ReadtDrive ( some info above from Vista
Resource Kit). but Vista "OKs" an external device for ReadyBoost primarily
based on the HD index and uses an inded of "5" as a base - which is why most
defvices are usuable with laptops.
Assuming the hybrid HD has an expereince index higher than "5" (5.9 is
max) - an external device would not be utilized by Vista? (Confusing)
