Recommendation for buy Hardware


I would like ask a recommendation  about HDs for Linux, because I use Squeeze and don´t want have the same problems that people that bought WD20EARS disks, my budget is limited.

I plan buy one ST32000641AS for my desktop/server and one ST2000DL003 for use for backups purpose via an external esata box.

The ST2000DL003 is 4096 bytes per sector, can this have problems with squeeze?

The ST32000641AS is sata3, but will be connected to an sata2 motherboard, so, can have any problem for this in Squeeze?

Thanks for the recommendations
