Mixed Random Read/Write Performance
For full details of how we conduct our Iometer tests, please refer to this article.
Mixed random performance is slightly below the average, but not catastrophic, and power efficiency appears to be rather good.
Where the SM2256 loses is in write performance, because performance is on par with the SM2246EN before moving to 20/80 and pure writes.

Mixed Sequential Read/Write Performance
Mixed sequential test seems to separate the planar TLC drives from the rest because both the SM2256 and Ultra II are at the bottom. The SM2256 is higher performance and more power efficient than the Ultra II, though, but it can't keep up with the MLC drives.
Again it's the write performance where the SM2256 loses to its MLC competitors because instead of having a bathtub-like curve the performance pretty much just decreases as the share of writes increases and evens out after 40/60.

The benchmarks seems very lacklustre and similar to much older controllers/SSDs. I know it's still probably not optimized, but unless SSDs using this can REALLY get the price down, I don't see why people won't just go with the older SSDs like. Heck, even new SSDs like the 850 EVO can be had at a very competitive price.watzupken - Wednesday, June 17, 2015 - link
Having experimented with a couple of value SSDs running the older SM2246EN controller, I feel they are not too bad for the price. For most users, I don't think they will run into much performance issues with these drives and will still enjoy a better user experience than running a mechanical drive. If you are getting a new SSD running an older controller, its likely you won't find it cheaper cause its older.NeatOman - Wednesday, June 17, 2015 - link
Thats true, but paired with a i3 or anything AMD in which such a small margin when the Systems controller (like in AMD's AM3+'s 990 chipset) is the bottleneck or simply the processing power like with a i3 or lower.And i feel the 850 EVO 120gb at $85 is still much more expensive than a SSD you can pick up with almost the same day to day performance for $55. It's like comparing a desktop i5 to a desktop i7 IMO.

Everything you write here is just complete garbage.leexgx - Saturday, June 20, 2015 - link

TLC for everyone....this is not a welcome. :(SunLord - Wednesday, June 17, 2015 - link
TLC is nice for low end low use scenarios but that about it.Flunk - Wednesday, June 17, 2015 - link
This would have to be really cheap to be interesting.Hulk - Wednesday, June 17, 2015 - link
My thought exactly.
