Slow SSD write performance (Agility3)

yannis76 · 26 Mar 2013 at 22:35

Hi,

I have an Agility 3 240gb on Asrock Z77 Extreme4 motherboard connected to Intel sata3 port as primary OS disk.
The benchmarks show quite a slow performance especially in writing...
Compared to various reviews I get about half the writing performance in AS-SSD.
These are my AS-SSD results:
Seq: 210,75mb/s--151,06mb/s
4K: 16,58mb/s--48,08mb/s
4K-64Thrd: 140,71mb/s--121,82mb/s
Acc.time: 0,213ms--0,299ms
Score: 178--185, Total:458

and Crystaldiskmark:
Sequential Read : 213.886 MB/s
Sequential Write : 139.253 MB/s
Random Read 512KB : 202.691 MB/s
Random Write 512KB : 130.550 MB/s
Random Read 4KB (QD=1) : 25.265 MB/s [ 6168.2 IOPS]
Random Write 4KB (QD=1) : 57.765 MB/s [ 14102.8 IOPS]
Random Read 4KB (QD=32) : 124.424 MB/s [ 30377.0 IOPS]
Random Write 4KB (QD=32) : 139.512 MB/s [ 34060.6 IOPS

Any ideas?

The system feels snappy and fast though...

I don't know how to insert an image,but in ATTO it starts from:
0,5KB: 14646--12895mb/s and ends
8192: 528936--555383mb/s

Hope its working

Hi again,

Atto is like the picture u attached, but are the other benchmarks not on par with mine?

yannis76 · 29 Mar 2013 at 17:29

Are u actually using the z77 extreme4 board? I see on the results u attached that the controller is AMD...

Is it possible that since i have connected all my sata devices to Intel ports the speed is slower?
Apart from the agility3 i have a momentus xt and a 2tb disk and a dvdrw.

People,

It seems I am running in sata2 although I dont know why...
I have downloaded HW Info and is says ATA5

yannis76 · 30 Mar 2013 at 00:30

I just tried to install the Intel rst drivers but computer hangs while restarting in windows logo...any ideas?

yannis76 · 30 Mar 2013 at 09:43

Some more info.

Although achi is selected in bios and sata 3 is shown in uefi, all my disks work in ata100. Both hw info and hd tune show ata6 supported but ata5 as active. This happens for all 3 disks so i don't think its the cables. Any ideas?

yes you wont be able to use them if your running an amd board,you can do system restore to before you installed them to get rid of them

I thought you had an intel board

But I do have an Intel Z77 board!!!
The AMD board was from another poster...

How About Bios Update ?

no difference...Just updated from 2.70 to 2.80.
I am not sure what is going on, since ATTO is showing more than 515MB/s read/write speed

I think its actually working fine. I also downloaded the CrystalDiskInfo and there the transfer speed for both disks is Sata/600
