Meh.... whatever is on sale. Just back up whatever you have...
I used exclusively Western Digital Black, and continued purchasing Blues when I was getting Seagate NAS drives for my server. The Barracuda 2.5" that I linked, like the Fire-Cuda (whatever it's called but that's close enough), is a recent entry in the market, and the 2.5"-er is targeted at both laptop and AiO desktop systems. Since I only need so much disk capacity in a workstation, I think it or any future Cuda disks of greater capacity -- 2.5" or 3.5" -- will have continued interest from me if this Barracuda proves out.
Let's say "I'm trying it out." there are other interesting 2TB drives (possibly greater) in the laptop or 2.5"-internal form-factor. There is an HGST Travelstar and an M9T Samsung-Seagate 2TB drive. We've been running another WD 500GB Blue laptop drive in another household desktop for about two years.
My storage strategy anticipates certain categories of usage, with a two-tiered caching scheme that makes the sustained throughput spec of an SATA-II or -III disk of any kind slightly less important than it otherwise might be. Otherwise, I'd probably buy WD Black or top-end HGST drives. But the way these lappie disks are planned in my usage, poses less wear and tear on them.
Enterprise drives such as those mentioned by Torn Mind would be good choices for fulfillment of a RAID option, but there are plenty of consumer drivers to choose from depending on your plans and usage patterns.
