Y700-15ISK PCIE SSD limitations?

2017-02-05, 10:14 AM

Hello, I want to upgrade y700 with fastest SSD such as PM961,  Samsung 950 or even 960 EVO. But I was reading that there are bottlenecks preventing full potential of PCIE SSD. One user mentioned that limitation is due DMI 2.0 to reduce power consumption but that could be fixed by BIOS upgrade. http://www.geektech.co.nz/lenovo-y700-samsung-950-pro

So I want to know before buying that these limitations can be fixed or I should stick to SATA SSD?

Hello avalon11,

 

Thanks for using the forums.

 

I would say there is not going to be much noticeable difference if you do upgrade, even if you would, it might be worthwhile to invest in an actual Desktop to customize and upgrade, but that is just a personal opinion.

 

Then again this really depends on your situation, I would say stick with what you have and save up for something "meatier"

The most noticeable benefit is when you upgrade from an HDD to an SSD.

 

Although different SSDs may return slightly different speeds when test programs are run, I really doubt that you could tell the difference between ANY of the currently available SSDs during normal use (web browsing, email, word processing, spread sheet, photo editing).

 

If your Y700 does not currently have an SSD, buy one of the ones specified in the "Hardware Maintenance Manual", as then you can be sure that it will work.  If your Y700 already has an SSD, but you want a bigger one, buy one that is in the same series as the ones listed in the HMM.  If your Y700 already has an SSD and you want a faster one, don't bother!

Hi,

 

I have the same question, however I don't have any SSD drive at the moment, only HDD. I consider Samsung 970 EVO, but if this bottleneck is true that doesn't seems too much sense to install this SSD, is that correct? Can you please confirm if the BIOS version CDCN54WW that settings is still limited to PCIe Gen2? What M.2 SSD are recommened now as those from Manual are not available on the market anymore.

 

Thank you in advance
