I'd look at longevity, if anything. I saw in some statistics that SeaGates are the harddrives that fail most often compared to the other big brands.
Everyone also hypes over Western Digital, but I've had a few of those fail randomly, as well. Friends have had the same experience with Western Digital, but stastically they're okay.
I'd also avoid Samsung HDDs. While their SSDs are great, their HDDs didn't last me long, either.
...As you can tell, I've had a few harddisks fail on me, new and used, but I actually still have a Hitachi DeskStar in my system which I've been using pretty much every day since 2008. Those are cheap and reliable, so I'd recommend them.
In the end any 2.5 inch drive you'll get will do. Whether or not it'll last you long largely comes down to luck. Performance isn't gonna be noticably different.
