Obviously the 960 pro is the fastest and more expensive choice.On the other hand the 860 evo (which is still a SATA drive not a PCIe NVME one) is the slowest but also the cheapest. I think that the better choice is the 960 evo which lies in the middle, performance and price-wise since its performance is fast enough (closer to the 960 pro) and you'll definitely feel the difference vs the 860 evo. It's price won't also break the bank and because of that you can get a larger SSD. The 512GB 960 pro and 1TB 960 evo are pretty close in price. However if you have the available budget and your workload involves a lot of data writes on the SSD then you should get the 960 pro. Good luck.
Thanks for the suggestions. Sometimes within the same series, larger capacity storage is faster than smaller one. For example, 2T may be faster than 1T. What about this case?
My motherboard manufacturer mentioned that there are two nvme m.s slots on the board. m.2_1 supports bigger SSD physically given that the ssd will be standing vertically on the motherboard. As for m.2_2, the ssd will be connecting in parallel to the mb like a person lying on the floor. "The numbers 2242/2260/2280/22110 denote the size of the Hard Drives that can be used. M.2_1 goes up to 22110 while M.2_2 does not. I cannot find the sizes of the 960 evo and 960 pro. I asked Samsung but the guy said that he had no idea! Do you?

The 960 evo and 960 pro are 2280 and almost all NVME M2 drives use the 2280 size specification, so you should't have any problem. Just be careful with the vertical slot because the SSD will be more exposed in that position and more prone to accidents. As for your first question, yes larger SSDs in the same series perform better than smaller ones and performance drops a lot with smaller drives. For example the 1TB and 2TB models will share the same performance numbers, but the 250 GB and 500 GB models won't. The smaller SSD drives in a series will have the biggest performance drop but usually at around the 500GB capacity point that effect becomes less noticeable. So a 500GB model will be pretty close to the 1TB one performance-wise. Their biggest difference is off course the capacity and the larger endurance number that usually comes along with each capacity increase. Good luck.
Thanks. Do you know if the overall system performance will decrease if I use both m.2_1 and m.2_2 slots as they may take out additional PCIe lanes if both are occuplied?
Thanks for the warning about that vertical slot. Is it better not to use it? I have two configurations in mind: 1) a small 500GB SSD for Ubuntu Linux OS and applications and another 1TB-2TB SSD for data or 2) a big 1TB-2TB SSD to store the OS, applications and data.
The first case may be better if both SSD could be inserted into the mb horizontally. In this case, which is better?
Shall I use 960 evo in both cases as it has very similar performance as the 960 but cheaper? If I use 2TB, I can only choose 960 PRO as 2TB is only available in the PRO series.
I don't know about the hard drives made in recent years. I always got hard drive failures 20 years ago. Always heard click click click sound and HD failures.

You will have to read your intended mainboard's manual...some can allocated 4 lanes to each M.2 slot, and some can only run a 2nd with 2 lanes bandwidth, but, still fast anyway. One of the newest Asus X470 boards allocates 4 lanes per slot, and is tested at 6700 MB/sec reads with two 960 Pros in RAID 0...

Yes, you do have to read your motherboard's manual and check whether there are some limitations imposed by the manufacturer. Also the M2 slots may have shared resources with other PCIe slots. Finally the total number of the available PCIe lanes depends on the CPU you have installed. As you can see you must read that manual.
As for the vertical slot, you can certainly use it but you have to be careful. Usually those slots are used for small SSDs or WiFi cards. It also depends on your PC case and how close that slots is to other cables or components. It may be protected or exposed and it depends on you configuration. If you are careful, you'll have no issue, but you have to plan ahead.
The SSD configuration you'll choose depends entirely on you and your available budget. You can also use an HDD for some "cold" data in order to lower the total SSD capacity, or you can you can also get a SATA 850/860 evo as a second SSD for applications and data. You don't have to get and M2 drive for that purpose. You probably won't notice any difference and it's much more cost effective. You can get an 500GB-1TB 960 pro or evo, as an OS drive and use a SATA 1-2TB 850-860 evo for data. Finally a single tip that I use is to choose a small drive (250-500 GB) for the OS, in order to make my life easier when creating back-up images for that drive. Since you have to frequently back-up the OS drive, it makes your life easier if it's smaller drive than a larger one (1TB+). Good luck.
