Upgrading from a Hard Drive for main os and gaming, video editing/encoding. I have extra Hard Drive for storage. For the exact same price i can take 1x Crucial RealSSD C300 128GB or take 2x Crucial RealSSD C300 64GB. Reading 600mb + in raid that is pretty dam fast, but would i see the difference really ? beside 300+ and 600+ read speed. Plus getting 128gb make place for future raid 0 use with price drop.
