The largest PATA notebook HDD is the aforementioned WD Scorpio Blue 320 GB. If you look for the exact specs, here is the link to the manufacturer's site:

This is also the fastest PATA HDD you can get. (I think, forum member
sjthinkpadder had a topic of comparative researches and results of PATA notebook HDDs, SSDs somewhere in the forum, it's worth to look at it.)
I got this path last year with a nice Flexview-screen T42, again thanks to
ajkula66, which was passed recently to a friend's wife (who utilizes the IPS screen better than me, because of picture-editing), only without the SATA-SSD-in-Ultrabay-caddy option. I purchased 2 gigs of RAM, I had a 320 GB WD Scorpio Blue PATA HDD, etc. I used Windows 7 (32 bit), which runs nicely on that setup.
However, if I could start again (maybe with an even nicer T42p with UXGA Flexview screen, who knows

), I would take a different path. I like the Ultrabay slot with optical disk drive (I occasionally use the ODD, but I cannot say I can rid of the optical disks yet), and there's an option for internally using a micro-SATA 1.8" SSD with an IDE-to-micro-SATA converter and a specially designed caddy. There is a topic about this, it's worth reading:
http://forum.thinkpads.com/viewtopic.ph ... 2&start=60 As I read, even TRIM command is supported with the right OS (if you choose an SSD, which is capable of it), which is a huge advantage of contemporary SATA SSDs. (PATA SSDs seem not capable of TRIM, but OWC has PATA SSDs in the market, which have something similar method, thanks to the Sandforce controller inside.
http://eshop.macsales.com/shop/SSD/OWC/ ... Legacy_Pro - For me, the OWC SSDs are out of question, I cannot see on their site any option of shipping to Hungary.)
In my opinion, the cost of the micro-SATA SSD + caddy is probably equal or less of the cost of the largest PATA HDD + SATA 2.5" SSD in Ultrabay or a decent sized PATA SSD. And even when it's time to depart from the T42, you can use your SATA SSD in another notebook (even if it's 1.8" sized, with a proper caddy & converter, which are cheap). But I prefer to use docking stations at home (with large SATA 2.5" HDDs & Ultrabay caddys inside) and SSDs and external HDDs "on the road" and probably my habits will not meet your intentions.
