SATA or PCIe NVMe SSD for Thinkpad T470?

Hi,

Planning to upgrade the T470 with an SSD and trying to decide between Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD:

https://www.amazon.com/gp/product/B00OAJ412U 

For an extra $86, I could get this drive, adapter and cable:

Samsung 960 EVO Series - 250GB PCIe NVMe - M.2 Internal SSD (MZ-V6E250BW)
https://www.amazon.com/Samsung-960-EVO-Internal-MZ-V6E250BW/dp/B01LYFKX41

Apparently, the 960 EVO would give me about 2 to 3 times faster performance than the SATA SSD.

Which one would you guys choose if it were you considering the usage is mainly coding and watching videos? Any insights would be great. Thank you. :smileyhappy:

The M.2 will have better performance no doubt. I personally use the 960 EVO 500GB for my rig and its wonderful. There isn't much consideration if you are only using the system to "Code and watch videos" honestly if you have the money. I mean the only benefit you have is loading up the browser and coding application and after that its pretty much a moot point.

Either will suffice based on your description!

I would be inclined to use the SATA SSD drive as that is what the machine is engineered for. It will still be plenty fast in that machine. My X1 was engineered for NVMe and that is what I use in the X1

I'm not familiar with the T470, however, if the adapter is adapting the SATA connection then there's no point - SATA is the bottleneck.  If you're adapting another port in the system that's essentially a PCIe port, then it may make sense to get the NVMe.

Mine works non-stop and with one or two machines running at the same time is lots of use.

Laptops do heavy duty work and I do more with my own laptop than most people do with Desktops.

I am NOT a limited person or thinker.

I have used all samsung ssd products and they always went off line or slow in with all t4xx laptops I have used for years
but as soon as I switched to crucial all my problems went away
also I built entire storage farms with samsung they failed madly as I switch them for crucial my life got easier

Not true for me in any of our Lenovo products - all clients. Maybe you got a bad batch.

Thank you so very much everyone for taking the time to write back. Really grateful to all of you. James Bunch, John Hurst, Lee W, and art lee! :)

Based on your comments, I decided to give up on the 960 EVO and instead use that money to get the 500 GB 850 EVO.

Just wondering if the 860 EVO ($20 more) that comes with improved write endurance is better to get than the reliable 850 EVO? 5 of our computers are running fine with 850 EVO.

I had 840 EVOs before and two of those stopped working, which makes me leary of the brand new 860 EVO!

Thoughts? Thank you again..

i wonder if you'll benefit much in speed from the NMVe drive, since it's connected to the sata port

Thank you immensely all 4 of you! :)

Went ahead and ordered the Samsung 860 EVO 500 GB and couldn't be happier with the decision after assessing all the options.

Greatly appreciate your time and wisdom. :)
