As is self explanatory, I have seen a lot of 2.5-3TB internal disks being launched in the past few months. These incl. WD Greens (lower power and speed) and recently Barracuda XT (performance). The OS installed on my PC (windows 7 enterprise x64) can handle it and planned 2011-12 hardware changes (UEFI BIOS, sandybridge, etc) should take care of the hardware too. In the meanwhile, I am stuck with a x58 MSI X58M with core i7 920. I can buy the 3TB ones but do not dig too much the HBA system of WD unless it is idiot-friendly. Seagate Barracuda XT has a software oriented fix (discwizard, etc) which they claim works. However, I do not want this to be a primary disk (OS) unless it is performance oriented. As a storage disk, can I make these work and have say 2-3 partitions on this using partition wizard, windows 7. The bigger issue is the availability and the difficulty of returning the disk if it does not work. These disks are not easily available in India, and I can get it from UK when my brother comes visiting in Apr-May 2011. Please help with your experiences if any of these disks specifically for windows 7 (boot disks or otherwise).
