One of the reasons i never bothered about the X models is the absence of
the UltraBay included with the larger T models. Typically, when sold,
the UltraBay is occupied with a nowadays rather useless optical drive.
Instead, lots of users use the Ultrabay either for a secondary battery
or HDD adapter, which can stay permanently installed if required. I
wouldn't really want to bother with USB sticks, given that the higher
capacity ones .

This is a BIOS mod for Santa Rosa chipset based Thinkpads T61 and X61 to
release and enable the artifically limited SATA II capability of the
chipset. Unfortunately does not also apply to the former *60 Thinkpad
variation. I apply this BIOS to every T61 that goes through my hands.

Nonetheless, the performance boost is slightly overestimated in my
opionion. While it enables the full SATA II potential for transfer
speed, this is hardky what makes SSD's so attractive. The added benefit
and most important performance boost of SSD's is due to the superior
random access times, which are not subjet to any SATA speed level. Any
SATA I level Thinkpad will always tremendously benefit from those higher
random access times.

Not only this. They also sacrificed the very convenient UXGA IPS
displays of the 15" T60 models, which is one of the main reasons i
joined the Frankenpad builder league. For people like me, machines of
the T6* generation are already fast enough for my actual requirements
(which do not include Youtube or gaming), and i am not interested in any
newer Thinkpads missing the much more convenient display resolution and
keyboard options. Apparently, i am not alone. ;)
