Slow Z77 SATA HDD speed

[naquaada]

Hello,

 

during copying data to a new system I noticed some issues. I'm using on all drives a similar partitioning system

so it is possible to clone partitions using Disk Utility instead of copying the data filewise.

 

I own three Seagate Barracuda ST5000LM. These are 15 mm high 2,5" drives with 5 TB capacity. So the data desity

is very high. Still all three are in last place, even when connected to SATA 3. Even a thirteen year old WD Blue

WD10JPVX - also 2,5" - had better scores.

 

Unexpectedly for me was the winner of my tests, a Samsung 2 TB mSATA drive. These are to find in the Samsung T3 or T5

external SSD's. From the looks it seems to be a Samsung 850. I have not expected that a 9 year old mSATA drive ripped

out of an USB-C device is better than my other SSD's. The weirdness increases because this drive has some faulty blocks

which are not shown in the SMART information. I had to leave some areas unpartitioned to avoid these problematic blocks.

 

 

Had somebody else noticed slow hard drive speeds on the Z77 chipset?

 

Greets, naquaada.
