Bought a Sandisk Ultra II SSD and about to install it. Just came across the potential issues with trim on third-party SSDs. This hard drive is for my girlfriend's 2011 Macbook Pro, so we're looking to get maybe one year out of it. Should I return the Sandisk and buy an SSD that has trim support (e.g., from OWC)? Or can I wing it with this one for a year?
