ADATA XPG SX930 (120GB, 240GB & 480GB) SSD Review: JMicron JMF670H Debuts
by Kristian Vättö on July 16, 2015 10:00 AM ESTAnandTech Storage Bench - The Destroyer
The Destroyer has been an essential part of our SSD test suite for nearly two years now. It was crafted to provide a benchmark for very IO intensive workloads, which is where you most often notice the difference between drives. It's not necessarily the most relevant test to an average user, but for anyone with a heavier IO workload The Destroyer should do a good job at characterizing performance. For full details of this test, please refer to this article.
The SX930 doesn't perform too well in our The Destroyer trace. If this was a value-oriented drive, I would say the performance is decent, but any drive that is focusing on the higher-end segment should outperform the BX100 and 850 EVO to have any chance of being competitive.
The number of high latency IOs isn't particularly large, but again the SX930 is only competitive against the value drives.
Power consumption is fairly average for the 480GB model, but the 240GB consumes substantially more due to its lower performance.

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?zodiacfml - Saturday, July 18, 2015 - link
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?leexgx - Friday, July 17, 2015 - link
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
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)

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
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?DigitalFreak - Sunday, July 19, 2015 - link
He's mesmerized by the flames on the box.
