Western Digital Black 2TB Read Drops

Recommended Posts

I bought a brand new WD 2 TB Black HDD two days ago with the model WDC WD2003FZEX-00SRLA0
I started by benchmarking it with HD Tune Pro in read mode. The results are pretty much concerning as the read speed, despite reaching a maximum read speed of 194MB/s, it drops in minimum read speed to 1, yes ONE, MB/s as it appears HERE.

Today I made the same test and got similar results with really huge drop in read rates reaching 22 MB/s as it appears HERE.

I have a WD Green, model WDC WD10EZRX-00A8LB0, which is a couple of years old. It never showed such drop in read speeds as my Black one did. (Screen HERE)

Do you think it's a faulty and unstable drive that I should replace? or is it normal behavior for this model?

You could try a return to see if a drive defect is coming into play with this. What is actual performance like (moving files on and off the drive?)

Thanks Kevin for your reply.
Retailers where I live aren't really that friendly when it comes to returns except when there's a real obvious problem with an evidence. In addition, I have contacted WD by email and they nicely referred me to use Data Lifeguard Diagnostics for Windows, which doesn't show read and write speeds basically. I made the quick test and, as expected, it passed without showing any further details. I have had an experience few weeks ago with WD's Lifeguard Diagnostics, where I tested a 6-year-old (power on hrs) terribly slow driver but it passed both quick and extended test just because it doesn't have any bad sectors, I assume.

As for your question, it is relatively fast if compared to the old Green WD I have.
I made a internal transfer, from a partition to another one in the same HDD, just for the sake of comparison. The difference is not that huge and in my opinion doesn't worth the high price for the Black WD.
The new 2TB Black HERE.
The old 1TB Green HERE.

Any thoughts??:(
