I agree short-stroking (using only a portion of the fastest area of the disk, leaving the rest entirely unallocated) can significantly improve spinning disk performance, because it reduces the normal (i.e. not calibrating) maximum head travel, which in turn reduces maximum seek times, which can reduce average seek times. This can cause lower RPM disks to perform as if they were high RPM.
I'm also disappointed that average seek was used throughout; even without using actual short-stroking, if you start with fresh drives dedicated to SQL data and/or log files, write properly sized files once (without growing them), it's very likely that all of the disk used will be at the "beginning" (outer edge), and will thus act as if short-stroked, with much lower average seek times.
Even without that, operations where the portions of the data files are close together can have the same effect.
Likewise, the article ignored sequential rates, which do matter - when you have a close enough approximation of a large scan of a large clustered or nonclustered index without fragmentation, in a filegroup whose files aren't (as a whole as well as individually) fragmented, on a contiguous allocation of dedicated spindles, which isn't in the buffer already, then sequential performance can become very important; this can particularly affect index maintenance and very large queries.
Note that a previous poster was incorrect regarding SSD's; RAID level can matter, and if RAID level doesn't matter (perhaps your controller or firmware or throughput path is the bottleneck), then a RAID level that provides more storage space at the same performance and a sufficient level of fault tolerance is clearly best.
The previous poster talking about a SAN with a "massive" cache may have a setup I haven't seen, but I'm hard pressed to find SAN's with more than 64GB of cache*, and even that's pretty rare; our SAN has about 16GB of cache (shared with all SAN clients), while our big SQL servers have over 100GB of buffer space.
For anyone that wants some raw data, here's a few 6 disk 3Gbps SATA local SSD setups on a modern controller in comparison to a few 10 disk 15k 4Gbps spindle SAN setups at various IOs outstanding - if you look closely, you'll see some odd effects. Every individual test was run for 1200 seconds to reduce cache effects.
