The reason I ask is 'cos I've never heard the HDDs for the H300 series described as 'high-shock protection' and I'm wondering if they are in some way less well protected.
I believe that the original iHP-1XX drives were MK2004GAL 20GB drives (and I suspect MK4004GAH for the 40GB drives although I can't confirm this). The vibration and shock specs on these drives are as follows:

Vibration
Operating 9.8m/s2 (1G)
Non-Operating 49m/s2 (5G)

Shock
Operating 2,450m/s2 (250G)
Non-Operating 9,800m/s2 (1000G)

Being newer, the H300 series players were equipped with MK2006GAL and MK4006GAH drives which appear to my untrained eyes to have twice the shock tolerance for operating and 50% extra for non-operating:

Vibration
Operating 19.6m/s2 (2G)
Non-Operating 49m/s2 (5G)

Shock

Operating 4,900m/s2 (500G)
Non-Operating 14,700m/s2 (1500G)

Certainly, the 20GB drives in my H120's were/are MK2004GALs. The hard drive in my H340 is a MK4006GAH. I have since replaced the (broken) hard drive in one of my H120s with a MK3006GAL, which has the same specs as the MK2006GAL and MK4006GAH drives.

Looking at the specs, the X006 drives are also more power-efficient and certainly sound quieter in operation than the X004 equivalents. They seem to sound less "clunky" than their older counterparts.

Looking at Toshiba's web site, the vibration and shock ratings for the new MK4007GAL are exactly the same as for the MK4006GAH:

Vibration
Operating 19.6m/s2 (2G)
Non-Operating 49m/s2 (5G)

Shock
Operating 4,900m/s2 (500G)
Non-Operating 14,700m/s2 (1500G)

The specs suggest that they are slightly more power-efficient than the X006 drives, but clearly the main difference is that the new drives are single-platter, so are the same form-factor as the original 20GB and 30GB drives. This means that they should fit inside a H120 or H320 (without having to remove any padding and crushing everything inside to get the case back on). Obviously, I haven't tried this yet, but I'm sure someone will, and confirm that it does/doesn't work in the fullness of time!

Full specs for the three drive ranges mentioned above can be found here:

MK2004GAL (H100 series)
MK4004GAH (H100 series)
MK3006GAL
MK4006GAH (H300 series)
MK4007GAL
MK8007GAH
