ASMedia 1061 PCI-E 8 ports controller

[Zippi]

Hi everyone,

i tried to install this controller: https://www.amazon.it/gp/product/B07L4R5DQM/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Chipset ASMedia 1061 - 8 ports Sata III - PCI-E 4X

 

everything works fine with no errors but..... HDD are viewed like this:

 

4TB WD Red - 6Gb/s - all OK

8TB IronWolf - 6Gb/s - all OK

8TB WD White Label ( shucked )  - 3Gb/s ( !!!!! ) 

I don't understand why these latest discs set them up like this. I tried to connect them to the motherboard SATA 3 ports and to another controller and obviously they are recognized correctly at 6Gb / s

Is there anything else i need to check or set? I do not understand why!

Any suggestions are welcome!!

 

Thanx in advance!

I wouldn't recommend that controller. It is a native 2 sata port PCI-E x1  controler with port multipliers.

 

A PCI-E x1 card only has enough bandwidth for 2 modern HDD so it will quickly become a bottle neck and you are likely to get drive errors, drives ejected from the array etc.

 

3Gbs is way faster than any conventional HDD.

Might not be, according to the description it has 4 Asmedia chips, and that would explain being x4, each Asmedia controller would use an x1 link, @Zippiplease post the diagnostics to confirm.

Yep, link speed issue is likely a compatibility problem, but it won't make any difference for current spinning disks.

Also note that assuming this really has 4 controllers, an Asmedia controller maxes out at around 200MB/s with both ports in use, so that will limit speed before the SATA2 link.

@Decto and @JorgeB thanx for your quick reply!

 

Now I'm away from home but when I return I check everything.

In the meantime I put back on the old SYBA SI-PEX40071 - 8ports SATA3 PCI-E 2X that see all the HDD well 6Gb/s

I had tried the ASMedia seeing that it was 4X thinking of improving the speed, I know that however with 8 HDDs connected both 2X and 4X there is the bottleneck but for my needs it was still fine.

From the tests I had done I had not seen substantial differences in speed. I remember however that using DiskSpeed it saw the ASMedia as 1X and it seemed strange to me, while it correctly sees the SYBA as 2X.

I think I'll move on to LSI SAS 9201-16i (LSI00244) HBA, if I read correctly it should work out of the box.
