Real-World Software Performance

Our real-world software tests don't differentiate high-end SSDs much. But there's a lot more variation between value-oriented drives in these benchmarks, proving that not all SSDs deliver the same user experience, even in the apps we use on a daily basis.

The products clump together in performance tiers. And it doesn't come as a surprise to see Samsung products at the top of our combined results chart. Its quad-plane flash and TurboWrite emulated SLC algorithm are just as effective in real-world use as they are in more synthetic measurements.

The SSD 750 EVO's planar flash does not recover as well from heavy writes as Samsung's 3D NAND. This leads to low performance under heavy use, which carries over to low performance when the drive is almost full of data.

Total Access Time

Low throughput under heavy loads and when the drive is full manifest as increased latency. Response time goes way up compared to other products in our charts, even when we give the 750 EVO plenty of time to recover.

Notebook Battery Life

Both 750 EVO drives perform amazingly well in our notebook battery life test. 3D V-NAND uses less power than planar flash, so the 750 EVO's performance must be at least partially attributable to Samsung's integrated DRAM buffer making up the difference.

    got the endurance wrong on the spec charts

    wow the battery life benchmarks on the 750 EVO is highly impressive, it make the 850 EVO's look power hungry. i wasn't expecting to see that at all esp from a non 3D V-NAND SSD. So if getting the most out of your battery life in your portable pc device is very important to you, then def the 750 EVO is the way to go.

    correct endurances.120gb has 35tbw and 250gb has 70tbw

    Of course they're intending these for system integrators, who get a marketing bullet point at a reduced price, and while their lifespan is inferior, the eventual failures will fall out of the integrator's default warranty period ("not our problem, buy a new one from us"). Personally I think this is a cheap move to milk consumers. Samsung should stick to the middle/high level stuff while they still have a good reputation at quality.

    While I do enjoy recommending Samsung's high end drives, I dont see this as milking customers. I would be more comfortable seeing a 750 evo inside a low budget system than kingston's SSD Now! drives. They saw a market in low cost, cheaper made drives. I am happy to see Samsung moving their old tech into this area. Its not the fastest, nor the highest quality drive, but it fits.
    I dont see Samsung's quality reputation getting hurt any time soon.

    I am confused. How is this good/better or useful? The 250GB 850 EVO is quite often available for $80. $5 less for inferior flash with less endurance. I don't get the point I guess.

    I see the price dropping once it becomes available. Otherwise I agree it wont have a place at that price.

    At twenty bucks less it makes sense, otherwise, it would be worth the extra twenty bucks simply for the longevity. Especially when the Sandisk Ultra II has similar performance to the 850 EVO in most capacities for a lower price.

    You're absolutely not wrong that the 750 seems to give about an hour more battery life than the 850 does, but let's remind ourselves that these plots were made starting at 500 minutes not 0 minutes. That's inherently deceptive, and obviously THG would say it's meant to show the variation more clearly, but the fact is that the bar looks like it's 70% longer (170 apparent units versus 105 apparent units), we should divide the values to reveal the true benefit: 10.7%. I may not be that inclined to get up in a tizzy about an extra 10% or an extra hour -- particularly when the 850 already allows 10 hours of usage -- but an extra 70% would be truly outstanding. Alas, that 70% is merely deceptive non-zero starting points on a graph.

    endurance is not that bad really unless you try to use it as a torrent drive or something silly like that. during the 3 yr warranty period for the 120 gb drive, you'd have to write 32 GB per day to the drive to reach the 35 TB TBW. sure the initial windows install and program installations will take up a bit of this but once that is done, day to day use won't get anywhere near this number for the average user.

    double this amount for the 250 GB drive since it has the same 3 yr warranty but a 70 TBW and you're even further than breaking this threshold. even storing data on it won't do much since this is usually written once and then read over and over. the reading of the data does not go against this TBW rating.
