I am planing a new build with AMD Ryzen 5 2600 and 8 GB DDR4.

I would like to add M.2 NVMe SSD to the syem, but can not decide which of following two. Right now they are almost same price in Amazon.com, with Samsung only $5 more expensive.

1. Samsung 960 EVO Series - 500GB NVMe - M.2 Internal SSD (MZ-V6E500BW)
2. MyDigitalSSD BPX 80mm (2280) M.2 PCI Express 3.0 x4 (PCIe Gen3 x4) NVMe MLC SSD (480GB)

Samsung is certainly more famous than MyDigitalSSD. However, MydigitalSSD BPX got excellent review and it is MLC, while Samsung is TLC (20GB more).

Any suggestion?

Samsung makes their own nand chips and controllers.
They can control specs better.
The specs for the 960 evo show 3200 mbps sequential read and 1800 mbps write.
The mydigital shows 2600 read and 1300 write.

The my digital specs on newegg are silent about the 4k qd1 random read rates which are probably the most important spec.

At anywhere equal price, the Samsung 960 is a no brainer.

Is MLC (Mydigital) suppose to have longer life than TLC (Samsung)?
 


Going purely technical MLC lasts longer.

Practical wise, your SSD will be obsolete before you ever have to worry about its lifespan.
 


Mostly irrelevant.
My system has 5x SSD.

Samsung 250GB 840 EVO
250GB 840 EVO
500GB 850 EVO (boot drive)
500GB 860 EVO
960 GB Sandisk

I just replaced a 120GB Kingston HyperX 3k (MLC) with the 860 EVO.
The Kingston was 6 years old.

The read speed of the Kingston was still near original. The write speed had reduced to 1/3-1/4 of original performance.
The 500GB 850 EVO has almost the same power on hours and TBW as the Kingston ddi. It is still performing at basically the same as out of the box.
The 2x 840 EVO's are 4 years old. They are still performing at near out of the box speed.

All 4 Samsungs are within a percent or two of original spec, no matter their age.
The Kingston is not.

And the Kingston had already been relegated to secondary duty, simply because of the size. Not the performance.
If I hadn't needed the extra space, and had not gotten a killer deal on the 860 EVO...the Kingston would still be in there.
