it has slightly lower endurance but they both are 5 year warranty, also the mx500 has an added bonus of features like hardware encryption (which is useful for a mobile NAS, because more chance of it getting physically lost), and has PARTIAL power loss protection that makes it sound like it could be more durable from errors occurring??? i don't have a ups, so i'll take whatever protection i can get (which is something the wd blue 3d does not even mention. Although they did released a newer NVME model that does have that feature). And performance wise, although both are acceptable, but based on the youtube real life performance demonstration moving 1,2,4,10gb files, it looked like the MX500 performed well, even when performance tanks due to running out of cache. the WD blue 3d claims not to have this issue, but when i see the youtube test, it clearly shows some issue. but based on the mx500 info, it rarely if ever goes below 200 MB/s consistently so i'm fine with that. but i saw the wd blue 3d was zig zagging alot below the 200 MB/s marker >_>:
the 860 evo is not even in my sights, not at those price points for my budget build. yes the endurance rating is great, if you want to pay for it. I do already have 850 evo m.2 sata ssds which i use on my ts-877, but they are unfortunately 256gb before i was using them as SSD cache acceleration, but later i switch to using them as QTS cachedev1 when i reinitialized. but having learned more since then, i'd next time stick to 500gb capacities for ssd, lesson learned.
i also checked with maxx and this what he said when i asked choosing between wd blue 3d vs crucial mx500 500gb roughly same price. I also asked about the SN500 while i was at it.

MX500. It's a bit faster. The SN500 is DRAM-less but that's less critical for a NVMe drive and WD does very well with the SN500 due to design decisions. But it's still an entry-level NVMe drive.

For storage/games, QLC is quite sufficient as are slower TLC drives (e.g. ADATA SU800, which uses especially dense TLC and tends to be the cheapest drive around at up to 2TB). Unless you're doing a lot of writes there, then you'd want to step up to a solid SATA TLC drive like the MX500/860 EVO, although I like the WD Blue 3D/SanDisk Ultra 3D for that;
these all come in the M.2 form factor generally at 1TB with a good $/GB. It can cost more at 2TB because most SATA M.2 drives are single-sided which means really packing in the NAND, driving up cost. (many NVMe drives are double-sided at higher capacities for this reason)
The SU800 lacks support for AES 256-bit hardware encryption, but does support DevSLP (Device Sleep)
the ADATA SU800 512gb seems to be rated for 400TB (TBW) endurance fyi. but curiously it only has a 3 year warrantyThe ADATA Ultimate SU800 512GB drive was didn’t leave us impressed during out testing and it doesn’t have anything to make it stand out in a crowded SSD market. A quick look at Newegg and we found that there are over 115 different 2.5″ SSDs available with capacities ranging from 480GB to 512GB and the ADATA Ultimate SU800 isn’t listed yet. To become a standout drive you need to do really well at something and the SU800 fails to excite and that is before we even start to talk about the pricing.
Our testing showed that we were able to hit 564 MB/s read and 519MB/s in the sequential benchmark (ATTO) and 83,000 IOPS read and 82,100 IOPS write (Anvil) for 4K QD32 random performance. These numbers are close to the drives rated speeds of 560/520 MB/s for sequential and 85k IOPS for random read/write performance. Our sustained write testing showed that sequential writes bottomed out at 40 MB/s and averaged 80 MB/s after the SLC buffer was full and data was being written directly to the 3D TLC NAND Flash.

techdeals recommended the ADATA SU800 but only if you could get it for a cheaper price than the MX500 or wd blue 3d. but only if you don't mind the lesser performance.
