Solve : Slow external HDD - normal??

1.	Solve : Slow external HDD - normal??
Answer» My external HDD seems very slow to me. Attached is a screenshot from a HD-Tune benchmark of the internal and external drives - is this normal? The 100Gb DRIVE is internal, the 25Gb is external. Also, why does the transfer of the internal drive vary so much, and go down as the test goes on, whilst the external drive stays relatively the same? The internal drive is ATA, external is USB2.0. Thanks in advance to anyone who can help me ANSWER these questions. If more info is needed then say so. Edit: attachment was missing, added now. Thanks for the heads-up WillyW.Bump?

My external HDD seems very slow to me.
Attached is a screenshot from a HD-Tune benchmark of the internal and external drives - is this normal?
The 100Gb DRIVE is internal, the 25Gb is external.
Also, why does the transfer of the internal drive vary so much, and go down as the test goes on, whilst the external drive stays relatively the same?
The internal drive is ATA, external is USB2.0.
Thanks in advance to anyone who can help me ANSWER these questions.
If more info is needed then say so.
