New SSD running too slow ?

[Shack24]

So I just updated a machine I Frankensteined together from some old hardware.

Got an Intel DH55TC mobo with a Xeon 3460 and 8gb RAM. And appears to be running SATA3 on the motherboard (hooked up to the first port....not the eSATA ones)
Have a new Seagate Barracuda 120 SSD 500gb hooked up with a barely used SATA cable (ZM599CM1A003)

After what appears to be mediocre SSD speeds that I was running in EIDE mode, finally got the board up and running in AHCI mode (thank god for Windows 10 System Repair), and my speeds appear nominally better in CrytalMark. Down to a 13 second boot so I can't be unhappy with that.....but any ideas on what else I may need to look for
No HDD hooked up at this time.....just the straight SSD for the whole system

Speeds too slow....or is this about right for a 10 yr old motherboard with average speed DDR3??
Wasn't sure how close this was to the 6GB that SATA 3 was rated for (assuming this is SATA 3.0....and not 3.1 or 3.2)
And cannot find any docs if this Barracuda 120 SSD has any Dram cache

I'd definitely be thinking that's running at SATA II.

Considering that board has a chipset with only SATAII (3 Gbps) ports, probably!

I completely missed the "assuming this is SATA 3.0" and thought they had actually checked.

Actually is a little confusing from the manual.....SATA 3.0....or is it SATA 3 Gb/s

Intel H55 chipset

So SATA II I guess it is.....well thanks folks !
