I've just bought the parts for a ~$650 build for a couple who are not very tech savvy, but wanted something future proof. I ended up with an H87 motherboard, i5 Haswell, a 120 GB SSD and a 500GB Seagate Baracuda HDD (plus PSU, case, 8GB ram, no GPU as they don't game). I would have got a 1TB HDD, but they honestly don't need very much storage, and I got the 500GB drive for $45.
If this was my own build, I'd not bother with an SSD caching solution if I absolutely didn't need the space for programs, and just make the SSD the boot drive. However, I think it might be simpler for them to operate if I just set it up as a single drive, with the SSD as cache. The Intel Smart Response is appealing because I can set it in the bios, and not have software for them to mess with. Can anyone surmise how much performance this would sacrifice? Will it really be a waste of the SSD? I've never used Smart Response myself..
Thanks in advance for the advice!
