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.

The 500GB EVO has actually been $164 at Amazon for like a week, making it the cheapest one on the chart lol... Not sure why they list it at $178.The 1TB just went back down to $340 too... I want two in the long run, trying to decide whether to grab just one now and wait for better BF pricing or just grab both now.

Yes, it's called the BX100. ARC100 is pretty decent, too.zodiacfml - Friday, July 17, 2015 - link
Nothing till other manufacturers release their 3D NAND versions. Don't forget about pricing too. ADATA couldn't compete because they don't design controllers or manufacture chips. They buy parts and assemble them, making it costly.Samus - Saturday, July 18, 2015 - link
Considering the MX100 is cheaper and more reliable with about the same performance, I think I just answered your question.Samsung TLC drives can not be trusted, specifically the 840 EVO and 850 EVO.

When it comes to budget drives right now, if it's not cheaper than a Samsung 850 EVO I'm not even going to look twice. The EVO is much faster in most reasonable workloads than any of the other discount drives so I can't see paying more for less.MrSpadge - Thursday, July 16, 2015 - link
I don't see the EVO being "much faster" than a BX100 or ARC100. I'd rather say they're about on par.Uplink10 - Thursday, July 16, 2015 - link
"initial firmware mostly focused on optimizing performance for benchmarks such as CrystalDiskMark and AS-SSD, which typically use higher IO sizes and queue depths"I do not believe what am I reading. They are optimizing firmware so it will look good on charts but are not optimizing the firmware for all uses that the users will perform.
Components for a PC are used in a lot of ways and optimizing the component for just a few uses that are similar as known benchmark software is wrong. The way I see it they are trying to sell the drive by optimizing the performance that will look good in known benchmark software. That is wrong!!!

It certainly is sad and unfortunately that is more or less the state of the whole component industry (smartphones having "Turbo" modes to exceed the TDP for improved benchmark scores). It's surprising how some SSD companies have very little understanding of real world client workloads and all they see is the few benchmark scores, which frankly are not even relevant to end-users.We are trying to fight the fight and convince manufacturers to focus on areas that matter. Getting JMicron to develop a new firmware just based on our feedback (they honestly had no idea why we are even testing low queue depth performance before I explained it to them) is a sign that companies value our input and expertise, which I think is ultimately a win-win for everyone.

And we users thank ya for it. AT has been instrumental in providing valuable feedback to SSD manufacturers since the early days, regardless of who was doing the writing.Maybe it's time for Kristian's own "SSD Anthology"... :p Seems people keep asking everywhere whether M2/PCI-E or NVMe drives are worth it for them, I know the stock answer is "if you gotta ask..." but still.
Maybe a one time revisit of some real world testing? HDD vs SATA SSD vs etc one last time to reassess how far the gaps have grown and whatnot.

" (they honestly had no idea why we are even testing low queue depth performance before I explained it to them)"That's a scary confession. Makes you wonder if they should find another area of endeavor and leave this market to those who *do* understand.
