Recently, there was an assertion erroneously made by myself...regarding transfer speeds of external hard drives compared to drives directly attached to the motherboard or to a PCI controller card.
Appreciate any inputs which clear my cobwebs.
I stated that data transfers using an external hard drive (either PATA or SATA) would be slower than such transfers done with the drive connected internal to the computer case. Although I really had in mind something else (data transfers between systems on a home network), my error has prompted me to do a little more reading.
Result? I now think that I was correct, if erroneous in my thinking
...I don't see how a USB bus allows for faster processing of data from a hard drive that is either PATA or SATA...than a PATA/SATA hard drive connected to the system bus.
I don't know enough about eSATA to include it in my analysis, but I encourage inputs about eSATA as well as my focus on internal vs external.
The logic problem that I have is...an external drive is ultimately going to be limited, not by the USB bus, but by the native abilities of the drive in the enclosure. At least, that's what I think.
Which means that a SATA drive will always be faster than a PATA drive...and a SATA II drive will always be faster than a SATA drive...and eSATA seems to be faster than both.
All comments appreciated, thanks
. Technical jargon is acceptable
