WD2002FAEX UDMA 5 and SATA 2.6?

My WD2002FAEX shows Supported: UDMA mode 6 but Active UDMA Mode 5. 

The reason i even was looking at this is the performance seems slow. See iamges below.

Especially odd to me is the slow read ties in the 8 to 64 range, this varies when in rerun the test but it’s always low in that area. I have another hd and it doesn’t look that way. 

And then the SATA shows as 2.6 instead of 3, what’s up with that? I bought this drive only a few months ago but now i’m wondering how old it is or if i got a lemon :dizzy_face:

Here’s info from HD tune minus the serial number.  I tried adding a jumper to the drive as a tech suggested, that did absolutely nothing. I tried the “universal firware updater” which another tech suggested, that seems to be for usb HDs and not internal. In any case it just repeats to unplug all usb hd except wd.  

Is there any thing I can do with this drive?

I’m wondering whether you have an “IntelliPower” Green drive that spins at 5400 RPM, or whether your drive has 4 platters.

Can you show us short-stroked HD Tune read benchmark graphs for your fast and slow drives?
