DOK220U3P, a US$30 hard drive dock that works

There's nothing particularly awesome about this Iview 2.5in / 3.5in SATA to USB 3.0 Hard Drive Docking Station, Model: DOK220U3P, besides the fact that it simply works.  I hooked it up to my Dell XPS 8700, and the copy of 250Gb of files take 30 minutes or so, a definitely respectable speed.  If the USB 3.0 dock works fine for another one week, then may be I'll just get another one.
