The Toshiba Canvio Basics 3.0 1.5TB hard drives have been appearing in electronic stores for a list price around $110. Not bad for an external portable hard drive that is USB 3.0 rated.

Being in the market for another external hard drive, these hard drives stood out on store shelves. The black plastic casing has a matte finish and looks relatively slim due to a beveled edge. When held in hand, it felt solid and flexed a small amount only when firmly pressed. Given the price range, the enclosure is solid.

Features, on the other hand, are also minimal. There’s a single led light on top and a single USB 3.0 Micro-B port at the back. That is simplicity at it’s best.

Included with the hard drive is a 17” USB 3.0 cable that also powers the portable hard drive. No AC adapter required.

Performance was fairly good with a slight caveat. Read speed was over 100 MB/s which is great. However the write speed was a little mixed. For file sizes 10MB and under the write speed was around 75 MB/s which similar to the WD My Passport 2TB. However, 100MB file sizes and above had a noticeable decrease in performance of 10 MB/s as read speeds were around 65 MB/s. To double check this, the benchmark was run two additional times, and results were the same.

Overall the Toshiba Canvio Basics 3.0 is a good external hard drive. It loses points for it’s inconsistent performance, but gains points for it’s lower suggested retail price and simple aesthetics.

Benchmarked below is the Toshiba Canvio Basics 3.0 1.5TB model formated to have a single ext3 partition.
