2.5 inch hard drives are generally cheaper and often faster than 1.8 inch and smaller hard drives. But as you may have guessed, they’re also larger, which makes them harder to fit into tiny laptops like the Acer Aspire One. But that doesn’t mean you can’t do it if you try.
Italian site Netbook News has put together a tutorial for installing a 2.5 inch hard drive in an Acer Aspire oNe A110 netbook. While Acer does offer a netbook with a hard drive and Windows XP, the A110 comes with a rather slow 8GB SSD. So if you want more storage or a faster write speeds, and you’re OK with voiding your warranty, you might want to check out the step by step instructions. Although the site is Italian, there’s an English language version of the page.
