The Patriot Hellfire M.2 480GB Review: Phison NVMe Tested
by Billy Tallis on February 10, 2017 8:30 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
Filled or not, the Patriot Hellfire manages to keep pace with the Intel SSD 750 and provide a higher average data rate than any SATA SSD can manage on the Light test.
The average service times of the Patriot Hellfire are slightly worse than the Intel SSD 750 and the more recent NVMe SSDs, but are still better than the Intel SSD 600p or any SATA SSD.
Samsung's 960 PRO and EVO are the only NVMe SSDs that don't show a significant increase in high-latency outliers when filled. The Patriot Hellfire's performance is essentially tied with the Plextor M8Pe and is comparable to most other MLC NVMe SSDs.
The power efficiency advantage of a good SATA SSD is very clear on this test, as the Patriot Hellfire and most other PCIe SSDs use two to three times the energy to complete the Light test.

The problem is that there's nothing cheap about these. In fact, price per GB for SSDs seems to be going up even for the 'just good enough' crowd! And after all these years capacities are still a joke. To me, those are much bigger concerns than the name given to the drive. But we're going to have to put up with it for quite a while by simply not buying anything. Companies are going to keep doing this as there's apparently a large part of the buying public who are determined to throw pearls before swine on overpriced and low capacity SSDs. At least Patriot has done SOMETHING about the performance aspect.Murloc - Friday, February 10, 2017 - link
you're wrong, I can now buy something double the size and with better performance at the same price I bought my 840 evo.MR_Roberto - Monday, February 27, 2017 - link
ehh? tell me what product that is.. i want to buy it xDphexac - Friday, February 10, 2017 - link
Now, that is one crappy SSD.jjj - Friday, February 10, 2017 - link
You guys should use these traces to measure power consumption in CPU reviews.There is way too much focus on "max load". Guess AT does have some more relevant tests for laptop reviews but in CPU reviews, the power section is tragic.

Unfortunately, these traces are just playing back the I/O, not actually re-running the whole application. The CPU load they present is trivial.jjj - Sunday, February 12, 2017 - link
Hmm so that can distort the SSD perf tests a bit for workloads that are CPU heavy.Maybe a dedicated article would be interesting. Even more so when you get Xpoint drives, next year i guess for proper capacities.
Guess the SSD power tests could factor in perf and CPU utilization for extra accuracy.

The distortion should be minimal. Recording the traces in the first place incurred very little overhead. The trace doesn't perfectly capture the dependencies between operations, but the playback does preserve the ordering and queue depths and relative timing, except that long disk idle periods are cut short. I'll cover this in detail in when I launch the 2017 test suite.BurntMyBacon - Monday, February 13, 2017 - link
Your efforts are appreciated.jjj - Monday, February 13, 2017 - link
Just to be clear, i was thinking the CPU becoming a bottleneck in some situations and that there might be significant differences in CPU load per unit of perf between SSDs that could lead to significant differences in real usage.
