a) which USB-to-SATA bridge is used (any user that currently has a PiDrive attached to a host might be able to post the output of ‘lsusb’)
c) how does the drive’s firmware handle the LCC (load cycle count) problem when I store my rootfs on the HDD (heads parked after 8 seconds and shortly after unparked)?
d) is it possible to adjust drive spin-down (when idle) through ‘hdparm -S’?
e) what about performance when used on a SBC without limited USB support? Eg. an ODROID-C1/C1+ or when using USB3.0? Anyone?
EDIT: OK, I found that WD uses a custom product ID (idVendor=1058, idProduct=07ba which is currently not supported by smartmontools) and that performance is as horrible as to be expected on any RPi with its only one USB2.0 connection: ~10MB/s according to this poster.
