Bests & Worsts Reviews from Amazon

It shouldn't take several seconds to backup a 4-megabyte photo. So I recorded how long it took to write a thousand files, each containing 100 megabytes of random numbers. For comparison, I did the same thing on the old Acorndata drive that this Canvio was bought to replace, and here are graphs showing the differences (mind the different vertical scales). Writing to the old Acorndata never took so much as 5 seconds, while writing to the Canvio took over 20 seconds about 1% of the time, and once took over 80 seconds. (The mean times were 2.8 seconds for the old Acorndata and 3.7 seconds for the new Canvio.) If you Google "why is my canvio so slow" (without the quotation marks), you'll see that other people have this same problem.
