Drives: Samsung 470 Series (SSD) And Seagate Barracuda XT (Hard Drive)
Hard Disk: Seagate Barracuda XT, 3 TB
We chose a high-end hard disk that combines solid performance with plenty of capacity to represent the whole spectrum of hard disks on the market. Seagate's Barracuda XT is a good representative in that regard. With 3 TB of space and a 7200 RPM spindle, this drive gives us high data transfer rates, decent (as far as disks go) access times, and reasonable I/O performance. While the SATA interface supports 6 Gb/s, we found that even in 3 Gb/s mode the drive hits its performance ceiling, clocking in at 160 MB/s.
With respect to price, this model is at the upper end of what you'll pay for a hard drive, and it'd probably be a likely option for the power user who hasn't yet made the decision to try out an SSD.
Seagate protects the Barracuda XT with a five-year warranty. Hitachi's Deskstar 7K2000 and 7K3000 (3 TB) or Western Digital's Black Edition 2 TB drives would be suitable alternatives offering comparable performance.

SSD: Samsung 470 Series, 128 GB
We've used these drives as reference several times in the past, though they're no longer the latest and greatest (for that, check out Samsung Goes 6 Gb/s: Is The 830-Series SSD King Of The Hill?). The 470 series is available in 64, 128, or 256 GB capacities, leveraging 3 Gb/s SATA interface. Compared to the most recent high-end models from Crucial, Intel, and any number of second-gen SandForce-based SSDs, this model isn't particularly modern-sounding. After all, it's last-generation interface limits data transfer rates to 260 MB/s. Some of the latest 6 Gb/s-capable drives can push sequential transfers beyond 500 MB/s. Our thinking here, though, is that even an older SSD is going to yield a significant gain over the hard drive.
Samsung, Intel, and Toshiba all design and manufacture the components that go into their respective SSDs (the notable exception being Intel with its Marvell-powered SSD 510). All three vendors have reasonable track records with regard to firmware issues, though none of them are perfect. The take-away here is that, even if the 470 isn't something a lot of enthusiasts would look to, the mainstream crowd is served well by this and any other number of modern SSDs.
