I want to provide an upgrade suggestion for Toshiba Satellite A505-600. It is an old laptop and there is a need for an upgradation. Now I am not totally aware about the specification and also want to know which hard drive support on that. The current drive is actively very slow and my client needs a upgrade for that. Now I am stuck with an choice for the upgrade. It is a laptop and if possible try to show me more upgrading options that I can go for. It is an tough choice to determine an upgrade for laptop. Thanks.
