However, if you plan to swap constantly, I'd recommend doing a prediction of the life-time. For normal usage, the number of possible write cycles should be sufficient. >=20 > 2) While my system rarely goes above using 2-2.5GB of RAM, I enjoy > having 6-8GB of RAM, just for the file cache.

How'd they work out? >=20 Ruggedized PC sitting on top of the rotor head of a helicopter, making videos of the blade movement. Works well, but the SATA connectors tend to fall off. ;-) Regards, Florian Philipp --------------enig11EFA159178725BF0D70EFF7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk4zzlcACgkQqs4uOUlOuU+QIwCePHGYrWHMkj8gRQ6ir/clMuAp HuMAn0x/5pWLf8WV7RYWpby43nYyzoeR =t84M -----END PGP SIGNATURE----- --------------enig11EFA159178725BF0D70EFF7--
