Zotac's Premium Edition 480GB closes the gap between other SSDs and Samsung's 850 EVO at its capacity point. There is not a lot of separation from one low-cost drive to another in these charts, but it's important to know that, over time, the differences do add up.
Total Storage Bandwidth
Here we see the tests combined and the results displayed in throughput. The highest-capacity Premium Edition SSD is right on the heels of the 850 EVO 500GB, and the same can be said about the smaller 240GB model. This is really surprising because high-density 128Gb dies have otherwise turned 256GB SSDs into the new 128GB SSDs, with less than desirable performance. There are few 256GB-class SSDs that we would consider purchasing because they give up so much speed compared to products in the next-highest capacity class.

Under heavy workloads, the Premium Edition SSDs are the best option available for the price. Their performance really is comparable to other mainstream SSDs, though without an emulated SLC layer to increase burst performance, they fall back into the pack with other low-cost products.
This is where Samsung's 850 EVO stands out, which is why it continues earning praise from non-professional users who own it.
Access Time Test
The access time results show a near mirror of the throughput tests. The Premium Edition SSDs whip through the heavy load iterations with a consistent flow that doesn't deviate from the path until the task eases up. They then settle in under moderate workloads and lead many of the other low-cost SSDs. Samsung's 850 EVO 500GB still performs a little better under light workloads, in part due to its TurboWrite feature (a marketing term for emulated SLC cache).
Notebook Battery Life

The Zotac Premium Edition SSDs fall into the middle of the pack when it comes to notebook battery life testing. The value-oriented drives we're including in the charts offer some of the best power numbers, often overshadowing high-performance SSDs in this discipline.
On notebook battery power, system buses run at reduced clock rates in order to minimize power consumption. This creates a bottleneck for many of the system components, and some SSDs adapt better than others. All of the drives in today's chart perform well though, delivering roughly the same performance.
Samsung Evo Pro 1TB with 10 year warranty is around $400-$450...
I say splurge a little and get the capacity, performance, and 10 years of worry-free storage...
Yes. I would be curious about this as well. This looks like a fairly nice drive and $140 for 480GB and Toshiba NAND looks pretty solid and a decent competitor to Samsung.
We tested the Q300 Pro (MLC version) and the review is in queue. We do not have the Q300 drive with TLC.
On the notebook battery life front, we measured the 850 Pro 512GB at 657 minutes. There are so many good drives available now and such a wide divide between the high performance and low cost models that we charts the drives separate.
There are size limits to for the performance charts. At some point I plan to list a couple of hundred drives in massive charts so everyone can see how they all stack up.
The 850 Pro is the only model from Samsung with a 10 year warranty. The 850 EVO carries a 5-year warranty. The SanDisk Extreme PRO also carries 10 years of coverage.
