D520 Hard Drive Speeds

I ran ATTO Benchmarking tools and it's showing speeds of ~30MB/sec reads. That's awfully slow and no where near SATA 1.5Gb/sec speeds.

Anyone else experiencing this issue? What speeds are you getting?

Thanks.

 

Expected. Hard drives have an internal transfer speed which goes through the SATA interface to the computer. The SATA interface isn't a bottleneck except for the fastest of SSDs.

Btw, belated welcome to NBR.

 

i disagree. the same hard drive used in another machine shows ~60MB/sec read speeds.

thanks for the welcome

 

What make and model is the drive in question? Also, what're the results of ATTO if you use the full range of block sizes?

 

It's the WD Caviar Black. Turns out it was old SATA drivers. I replaced and now I'm hitting 80MB/sec read and writes.
