Heads up on the T520 -- it does NOT come standard with an eSata port as advertised on the Lenovo website. Lenovo.com shows pictures of the T520 which clearly indicate an eSata port on the left side near the front, which they also describe as a USB/eSata combo port. I just purchased a T520 direct from Lenovo, with the 2.5 Ghz Corei5 2520M with the standard Intel HD3000 graphics, but without the additional Nvidia graphics upgrade. Instead of a USB/eSata combo port, mine came with a USB only port. At casual glance it doesn't look like a USB only jack but actually looks like an eSata port, until you either try to plug in an eSata cable or look really closely where you'll see little plastic stubs on the inner sides of this larger than normal port which prevent an eSata cable from being plugged in. According to Lenovo tech support the T520 does not come with an eSata port unless you order the model which has the upgraded video hardware. This is apparently noted in the details of the PDF tech spec which is downloadable from their website. In other words, Lenovo is falsely advertising the T520, as the pictures which show the eSata port do not indicate that it is an upgrade option, and then hiding behind the fine print in a separate support doc. Very misleading and very disappointing. Otherwise, it's a decent machine, just completely lacking in a high speed external port for data backups.
