Effectivement, eSata ne doit pas avoir ce genre de problème, on lit exactement:

"Some low-level drive features, such as S.M.A.R.T., may not operate
through some USB [34] or FireWire or USB+FireWire bridges; eSATA does
not suffer from these issues provided that the controller manufacturer
(and its drivers) presents eSATA drives as ATA devices, rather than as
"SCSI" devices, as has been common with Silicon Image,JMicron, and
NVIDIA nForce drivers for Windows Vista. In those cases SATA drives do
not have low-level features accessible."

in https://en.wikipedia.org/wiki/Serial_ATA#eSATA


Comme de plus l'interface eSata est logiquement plus performante, cela
permet de tester les performances du disque sans être bridé par
l'interface USB.

"Some single disks can transfer 157 MB/s during real use,[10] about
four times the maximum transfer rate of USB 2.0 or FireWire 400 (IEEE
1394a) and almost twice as fast as the maximum transfer rate of
FireWire 800. The S3200 FireWire 1394b spec reaches ~400 MB/s (3.2
Gbit/s), and USB 3.0 has a nominal speed of 5 Gbit/s."

Je vais devoir casser ma tirelire!
