Which one is more valuable ?!😍

( i want buy Geil zenith Z25R3
Reasons :
speed> similar to evo850
550mb / 510mb
Mtbf> 2.5 million hours vs evo850 2milion hours ! Seems better !
Guarantee : Geli 3years vs Evo850 2years
Geil 30$ cheaper than Samsung )

PC
Gigabyte Z170X Gaming7
Intel i7 6700K
Nvidia GTX 1060 msi Gaming X 6GB
HDD 3TB 7200rpm+1TB 5400rpm ( Toshiba and Western digital )
Gskill Trident Z 8GBx2 3000mhz cl15
Gp585watt power
Case Green Z2+Hero

Slow speed has frustrated me
I must buy ssd

Thanks for your replies

Out of the ones you listed, 850 Pro.

I'm generally all for people buying not Samsung but Plextor is not really a competitive alternative and I don't know wtf that Geil even is. I mean, I just looked up the Geil and I can't even find any basic information on it in terms of NAND or controller. Don't read too much into the MTBF. There isn't enough of a standard for MTBF and really, manufacturers can claim whatever they want. It'd be one thing if it's from a reputable manufacturer but I'm hesitant to trust those numbers from a brand that's not well known.

With SSDs, you really have to consider both the firmware component and the physical component of NAND and controller. Out of the drives you listed, 850 Pro has the best NAND and arguably the best controller, and likely the best firmware. So I trust it to be the most reliable out of this bunch.

Right - but i think evo850pro is not valuable-
Evo850 pro 120GB is 120$ but Geil Z25R3 240GB is 90$ but evo850 250GB is 120$ similar to evo850pro 120GB
In userbenchmarks evo850 pro128Gb performance lower than evo850 250GB
Evo850 pro 120GB weaker than evo850 250GB and weaker than evo850pro 250GB
And 250GB is so expensive

But now i want choose between one of this list
Evo850 250GB
Evo850 pro 120GB
Or go beyond and choose evo960 m.2 256GB its 180$ vs 120$ evo850

I'm speaking more from a long term reliability perspective.

With SSDs, you can get pretty much either TLC NAND or MLC NAND. Without going into the physics behind it, the most basic idea is that TLC crams more data into less silicon so that it's cheaper to make with the trade of being that it's more prone to data errors and has a shorter lifespan.

All of the cheaper entry level SSDs are TLC NAND. The next level up uses fairly entry level MLC NAND. That's the main difference between an Evo and a Pro, and is why the Pro costs more. Places where you'll see this is in read errors long term and endurance. The Pros are rated for pretty much twice as many writes as an EVO of the same capacity. For performance benchmarks, Pro should be better if both drives are conditioned properly. The performance on a Pro is less likely to degrade over time than an Evo.

For your use, a 960 is probably not worth it if you want to save money. You can likely get away just fine with a 850 Evo. Plenty of people do. Alternatively, I would also look at something like a Crucial MX200, which I would probably pick over a 850 Evo.
