ADATA XPG SX930 (120GB, 240GB & 480GB) SSD Review: JMicron JMF670H Debuts
by Kristian Vättö on July 16, 2015 10:00 AM ESTMixed Random Read/Write Performance
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.

It is more of a power-user scenario. I have a pretty fast desktop (i5-4670k, 16GB ram, Gigabyte Gaming-5 mobo) paired with an older (!) Samsung 830 128Gb boot drive. The computer, once you get past the POST, boots in seconds. Your average user would never notice a faster boot, since it's so bloody quick already.DIYEyal - Monday, July 20, 2015 - link
SSDs are far more than just fast boot.frenchy_2001 - Thursday, July 16, 2015 - link
As Anand used to repeat in most of its SSD tests, there is very little difference for typical client usage between SSDs. There are order of magnitudes between SSDs and HDDs (particularly useful for random access latencies), but once that jump is made, there is very little difference for client usage.Just check the "Storage Bench Light Latency" graphs. This is the ranking for typical client usage and most SSDs are in the same range.
Only enterprises and power users will really benefit from PCIe/NVMe storage. For the rest of us, any modern SSD is good enough.

To me this raises the question of what's next in client computing. Any half-decent PC today with an SSD already excels at most consumer tasks--web browsing, office applications, light photo editing, 1080p video, etc. Compute intensive tasks such as computer vision and natural language processing are being pushed to the cloud. Gamers have faster GPUs and next-generation displays (OLED, 4K, wide-gamut, adaptive V-sync) to look forward to, but aside from that there's nothing else in the horizon that gets me excited. Maybe VR is the next big thing?Kristian Vättö - Friday, July 17, 2015 - link
Unified memory architecture (i.e. no more memory and storage, just one type that serves as both) is really the next big thing. We'll likely see something in that front in the early 2020s.AnnonymousCoward - Saturday, July 18, 2015 - link
Are you saying a non-volatile technology will replace DRAM in 5 years? How could that possibly happen?Kristian Vättö - Saturday, July 18, 2015 - link
Not replace right away, of course, but in five years time the next generation non-volatile memory (ReRAM, NRAM, MRAM or whatever it ends up being) should start to be in meaningful production volume. Once that happens it will slowly start to replace DRAM and NAND, although that transition may easily take a decade, but some enterprise applications will probably take advantage of a unified memory architecture rather quickly.AnnonymousCoward - Tuesday, July 21, 2015 - link
Huh. I haven't heard of all 3 of those. But without even knowing about them, I can say in general it will be damn hard to beat DRAM performance and density/cost. Maybe in 2030.ATC9001 - Thursday, July 16, 2015 - link
Is there ever going to be a drive that challenges the EVO for price and performance? It competes with higher end drives, but is nearly the cheapest available...Refuge - Thursday, July 16, 2015 - link
Honestly idk...Samsung is very well set up in the SSD space right now, they have their own in house controller that is a very solid performer, and they are completely vertically integrated with some of the best fabs around.
