So any idea why the switch does not appear to be working correctly?

So any idea why the switch does not appear to be working correctly?

It is showing correctly as "SATA/600" on my laptop. Although I don't have a 2.5'' SATA SSD to verify that...

 
Current running on Microsoft SATA AHCI Driver. But even Intel RST driver doesn't seem to affect the transfer mode.

You would need to be running an SSD and not a platter drive for this to be very meaningful.

Definitely keep the drive.  If you need to RMA the laptop within the warranty period, we will expect you to reinstall the original drive before sending it back.

Hi Lee & EVGA,
 
First off solid solid laptop build. I have an EVGA SC15. I have a Samsung 860 Evo 1TB SSD that I installed into the SC15. Unfortunately I am having horrible read speeds from the Unit. 
After digging around, I am stumped as well. Here what I have done to troubleshoot:

• Re-seated ribbon cable.
• Benchmark SSD externally via USB (550MB reads & Writes)
• Updated to your 'beta bios' and selected gen 3
• Fresh Windows 10 Pro install
• Windows 10 drives gives the worst read speeds, but highest write speeds.

 
 
 

• Using Intel RST drivers. SSD shows up as SATA600 initially, but once i open anything up, ie program, game, or benchmark, the drives drops down to SATA300 (Gen2). Benchmarks Improves read speeds to 'GEN2' overall, ie 280MB READ & Writes. But not GEN3 as it should
• Attaching screenshot off benchmarks and driver. AFTER:

Can we get a similar BIOS for the SC17 980 and SC17 1080 laptops, please?

Unfortunately, this is one of the reasons why we can't support any other drives than the ones we include, as well as performance after a reinstall of Windows.  It's noted that we cannot guarantee the speeds or performance with this BIOS update as the laptop is not tested to use anything other than what was included. 
 
Have you tried the previous BIOS to test the performance to compare?  I realize it may be locked at SATA II, but it doesn't hurt to compare.  Then you may consider trying to flash back to the "beta" BIOS to see if the performance improves.

Hi Lee,
 
I tried the very first BIOS as well as the latest BIOS, and of course, the beta bios. Performance still suffers.
 
I'm curious as to what is so special about the original drive, that allows it to run at SATA3 speed. I'm even curious if the OEM unit even does SATA3? 
 
If you guys could send me a 2nd bottom panel, i'd be more than happy of doing that. Its just so tight, and I am always terrified of breaking the plastic tabs.
 

It is kind of ridiculous to release a premium laptop with only a Sata2 port, even though the HD that comes with it only uses Sata2 speeds.  Did the Beta Bios fix this?  Didn't quite understand from the posts if it actually resolved this issue for the SC15. Many custumers would like to upgrade to an SSD, like I did with my SC 17 1080, but my SC17 runs SATA3 no problem.

For me, the beta bios did not help.  The SSD still falls back to SATA 2.
