For full details of how we conduct our Iometer tests, please refer to this article.
The 480GB and 120GB do fairly well in mixed performance, but the 240GB is behind its peers. Although it is worth noting that the 480GB does also consume twice the power, making it not very efficient for use in battery driven platforms.
There is nothing spectacular in the scaling graphs. The performance scaling could be more aggressive with writes, but the SX930 doesn't have good write performance to begin with.
Mixed Sequential Read/Write Performance
The SX930 does well in mixed sequential performance and the power efficiency is good for this test.
The reason lies in good read-centric performance, which is surprising given that sequential read performance is the Achilles' heel of the SX930. Despite this it performs well with writes thrown into the mix, although again the performance when the distributions become write-heavy are nothing to write home about.
Kristian.. that's so shocking to hear! It's the same attitude which gave us the poorly performing JMicron controllers in the first years of SSDs. Was it 2009? It took Anand to explain them why their drives optimized for sequential performance s*cked in the real world. Did they learn nothing during all those years?
True yet both has a point. Even if they optimized for low queue depths, real world client workloads wouldn't change much such as booting Windows or loading some games or programs though benchmarks would show the improvements. I would like to see better random performance in all SSDs in the future but it's rare to have that kind of workload in clients and usually it is done so quickly.
They listened though because Anandtech is already respected when it comes to these.
But can you really blame them? Even Anandtech runs the standard benchmark battery and throws you some number. They don't test real-world scenarios, so why would manufacturers optimize for that?
Completely different market segment (medium SATA SSD vs premium PCIe/NVMe). You can still compare them with BENCH if you want to see what you get for your $$ (hint: lots if you need it, little in client usage)
Samsung has made 1 slip-up that was fixed with a firmware update, JMicron makes controllers that are consistently awful. Which one deserves more of your vitriol?

maybe you should be looking at the AnandTech Storage Bench part of the reviewsZeDestructor - Thursday, July 16, 2015 - link
No Intel 730/S3500 in the comparisons? :(frenchy_2001 - Thursday, July 16, 2015 - link

So JMicron is still crap after all these years. At least they're consistent.Oxford Guy - Saturday, July 18, 2015 - link
Not everyone can have a drive that slows down to 30 MB/s on reads like Samsung.The_Assimilator - Sunday, July 19, 2015 - link

He's mesmerized by the flames on the box.
