Mixed Random Read/Write Performance

The mixed random I/O benchmark starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. The queue depth is 3 for the entire test and each subtest lasts for 3 minutes, for a total test duration of 18 minutes. As with the pure random write test, this test is restricted to a 16GB span of the drive, which is empty save for the 16GB test file.

Iometer - Mixed 4KB Random Read/Write

The Patriot Hellfire has great performance on the mixed random I/O test, tying the OCZ RD400 and falling behind only the much larger 2TB Samsung 960 PRO.

Iometer - Mixed 4KB Random Read/Write (Power)

The Patriot Hellfire draws more power than the Samsung drives, but otherwise is one of the most efficient drives on the mixed random I/O test.

Performance increases slowly but steadily as the portion of cacheable writes increases, but the spike in performance when the workload shifts to pure writes is not as big as exhibited by some of the Patriot Hellfire's competitors.

Mixed Sequential Read/Write Performance

The mixed sequential access test covers the entire span of the drive and uses a queue depth of one. It starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. Each subtest lasts for 3 minutes, for a total test duration of 18 minutes. The drive is filled before the test starts.

Iometer - Mixed 128KB Sequential Read/Write

The Patriot Hellfire turns in the second-worst performance from a PCIe SSD, but at least it is still clearly faster than any SATA SSD. Even the 250GB Samsung 960 EVO fares better. This test is another sign that the Patriot Hellfire does poorly when full.

Iometer - Mixed 128KB Sequential Read/Write (Power)

The Hellfire's power consumption across the mixed sequential I/O test is about average for an NVMe SSD, so its overall efficiency is fairly poor.

The addition of a heatsink only slightly improves the minimum performance of the Patriot Hellfire across the mixed sequential I/O test, and actually led to slightly reduced performance overall.

    "...a Phison E7 SSD might make sense at the 120 GB capacity point where Samsung has no offering..."

    IF the performance of the 120 GB version is close to that of the 480 GB drive. It appears that Patriot isn't sending the lower capacity drives out to reviewers. The link given below reports that the 240 GB model providing about 86% of the speed of the 480 GB model. That number may not be terribly meaningful because the reported speeds vary a lot (presumably because some drives were fuller than others when the benchmarks were run), but it seems to be the best data we have. The law of diminishing returns suggests that the performance gap between the 120 and 240 GB models will be greater than the gap between the 240 and 480 GB models. So it seems quite possible that the 120 GB model is a real dog.

    So why is a supposedly leading tech site doing their review on Windows 8.1? There are already features and such unusable if you don't have 10

    We're purposely slow to switch OSes so that we can work out the kinks first. Win10 has taken a bit of time to get to place nicely with our SSD tests, though we should be ready to finally roll it out in the next couple of months.

    That basically means in several years when nobody is reading any more.

    After this review, I have two engineering samples and one retail drive that I'll be reviewing with the 2015 test suite, and then I'll be switching over to the 2017 test suite using Windows 10. If all goes well and if I get enough of the back catalog of drives re-tested with the new suite in time, the WD Black may even get reviewed with the new test suite and the 2015 data will just go into the Bench archives.

    But you're probably overestimating how important the switch to Windows 10 is for SSD reviews. The Windows 10 NVMe driver still sucks.

    windows 10 provides inconsistent results (unless you disable everything or use windows 10 LTSB and still disable everything) where as you can use windows 8 and have consistent results

    Newegg has a 1 TB Mushkin Reactor for $229.99 today. Until Nvme prices come down (the increase appears to be completely artificial as they are not more expensive to make) I will be on the sidelines enjoying my "slow" Sata 3 SSD.

    Interesting how several sites tested this drive, and:
    -AT criticizes it for being the slowest MLC NVMe SSD and not being price compeitive with the MyDigitalSSD BPX
    -Tomshardware also criticized pricing, wrt the 950 Pro (but they also had data on the BPX and showed the Hellfire slightly ahead)
    -thessdreview praises it for getting close to the 960 Pro and RD400 while being less expensive

    Everyone's probably right at once. From AT's price table, it looks like the Hellfire is a decent PCIe entry at 480 GB. It's cheaper than drives that outperform it while beating the cheaper BPX and 600p.

    But I don't think NVMe M.2 drives are worth it right now. They're expensive, power hungry, run hot, and are harder to cool (especially next to a graphics card). I have the M8pe, and it's often hard to feel the difference compared to a good MLC SATA drive. If software changes direction to be far more IO heavy it could be worth it.

    Ipl T20 2017 is likely to be scheduled to start from April 3rd 2017 to May 26th, 2017. While, opening ceremony and final match of IPL 2017 is to be placed on Eden Gardens, Kolkata.

    Perhaps unrelated but what is it with these naming conventions? Hellfire, Bonecrusher, Gravedigger, MurderBox. It's not badass at all, it's ridiculous.
