Western Digital Caviar Black 1TB Hard Drive Review

Read Bandwidth

For this benchmark, HDTach was used. It shows the potential read speed which you are likely to experience with these hard drives. The long test was run to give a slightly more accurate picture.

We don’t put much stock in Burst speed readings and the main reason we include it is to show what under perfect conditions a given drive is capable of; but the more important number is the Average Speed number. This number will tell you what to expect from a given drive in normal, day to day operations. The higher the average the faster your entire system will seem.


For what it is worth, the burst speed of this drive is certainly right up there with the best of them; however, its average read speed is a little on the low side…relatively speaking. Darn near 97MB/second read speed is still very, very good and considering this drive comes with a massive 1TB of storage space, its cost per GB is one of the best.
