hi
yes both drives show S.M.A.R.T-APM,NCQ,TRIM

benchmark on the SSD bay drive gives 100\100 read-write instead of 550\550

Are they displayed with grey or black text?
Grey = bad...

JK, seems that the connector or something else is limiting your speeds...

Black.

stupid question,
is there a way to program SATA port to switch mode? IDE to AHCI

Dude, from what I have read here, the following is the case:
- The SATA controller is running in AHCI mode.
- The drive has NCQ active, so it is running in AHCI mode.
- There is no IDE controller in device manager.
- It is not possible to set specific ports to another operating mode. Only whole controllers.

Therefore, all is well configured. You must have a bad drive, a bad connector, a bad PCB, a bad wire, bad shielding of the connector/PCB/wire or whatever.
You already got a replacement mainboard, so either you have a bad one again (that chance is pretty low) or
the whole production series has a flaw or you have a bad drive.

It is NOT a misconfigured SATA controller.

EDIT: Maybe you have disabled drives chaches? Just check in device manager, enable them and reboot.

so here is how far Ive gone so far:

BIOS set to Raid mode.(i didn't use the embedded raid controller)
installed win 8.1 Pro
get win drivers up to date
installed RST version 12.8.0.1016 (iaStorAV)
using Intel RST i created Raid0. the process was completed with no errors.\
banchmark results from ATTO and crystalmark were 550\550 ---meaning only one drive was involved in the banch.,

i then, restated the system and the optical bay drive was disconnected from the array. it went back to a single un-partitioned drive
here is the weariest thing i ever saw:
i have never been able to get 550\550 banch from the optical drive no matter which mode it was set to.
after the Raid got broken and the SSD in the bay drive got dumped from the raid. i created a simple NTFS volume, i ran ATTO and cryctal, and now im getting 550\550 from the SSD drive that is connected to the DVD SATA port 2.

@mr_nuub thanks for your reply!
there is an IDE controller on the device manager when i set the bios to AHCI mode.
when the Bios is set to Raid the device manager shows only the controller .

Conclusions?

Recap of this thread:
- there is a compatibility mode for optical drives (IDE) if the controller is set to AHCI
- set it to RAID (if available) and use appropriate drivers
- BIOS modding on mobile devices is very risky and therefore not recommended

/vote for sticky or wiki

I set it to raid and tried to get the optical drive to work on two raid options.
1. using the embedded controller
2. set the bios to raid and use RST and i think i have tried every version of RST drivers that are compatible with my system.

from this site the classic drivers (original and modded) 11.2.0.1006 which best match to my Rom version , did not work no no matter what i tried. windows 7 8.1 and 10

the only thing that driving me crazy is when i set the bios to raid and use RST 11.2.0.1006 to build the raid-0. the kicked out the optical drive from the array but this is the only circumstance that banchmarking the optical drive SSD provides 550\550
this is unbelievable. why the bay drive gets kicked out from the array?
what happens in the raid building process that makes the SSD to work as it should(as a single drive after it get kicked from the array) because banchmarking the drive in any other way would give me a 100\100 banch,.

there is one fact here. the optical SSD drive does work as it should . the SATA 2 and the bay DVD caddy adapter dont interfere.

help please?

hi
the fact that the drive was kicked out of the array doesnt bother me. what does is why only after the drive was part of the array then after a system reboot the drive provides 550\500 benchmark.

so my question is, if the bay drive as you said is not connected to the same SATA port --a raid could not be created, OK, make sense but, to which SATA port the bay drive is connected to after
it gets kicked out from the array? fact is, after the bay drive is out of the raid i reboot the system and the bay drive provides an SSD full benchmark performance (500\550)
