Sequential Read Performance

The sequential read test requests 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.

Iometer - 128KB Sequential Read

The sequential read speeds of the Patriot Hellfire are clearly slower than almost every other NVMe SSD, but it's still twice as fast as SATA SSDs. The TLC-based Intel SSD 600p falls in between the SATA SSDs and the Patriot Hellfire.

Iometer - 128KB Sequential Read (Power)

The Patriot Hellfire is also one of the lowest-power NVMe SSDs during sequential reads, so its efficiency isn't particularly poor for this test.

Near the end of the sequential read test the Patriot Hellfire's performance falters as it hits thermal limits, but the addition of a heatsink allows it to eventually catch up to the performance levels most other NVMe SSDs hit at much lower queue depths.

Sequential Write Performance

The sequential write test writes 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.

Iometer - 128KB Sequential Write

The heatsink makes a huge difference to the Patriot Hellfire's sustained sequential write performance, allowing it to pull slightly ahead of the Plextor M8PeY, but still leaving it far behind the OCZ RD400A.

Iometer - 128KB Sequential Write (Power)

The Patriot Hellfire's efficiency is worse than its competition both with and without a heatsink attached. With a heatsink, it hits the highest power draw of any SSD in this bunch, after discounting the power used by the M8PeY's LEDs.

Without a heatsink, the Patriot Hellfire is thermally limited by the end of the QD1 test phase, and performance is completely flat for the rest of the test. With a heatsink, the performance scales substantially from QD1 to QD4 before reaching thermal limits.

    It's sad that all these non-Samsung MLC NVMe SSDs can't even compete with the TLC 960 Evo... But then again, which has more endurance? VNAND TLC or 15nm MLC?
  • bug77 - Friday, February 10, 2017 - link

    V-NAND TLC has about the same number of p/e cycles as planar MLC.

    "Which has more endurance" is a false choice!

    You need to specify Brand, Process, Controller and Firmware Version when comparing endurance

    Mixing MLC and TLC also does not help in the least

    I pay less over time for a better process like 40nm Samsung MLC than I do for a cheaper process like 15nm Toshiba MLC, even though the initial cost of the Samsung is higher

    Likewise, you should only compare TLC with TLC

    The only Non-Endurance issue I've ever had with 3D V-Nand is that I had to update Acronis True Image from the 2012 version to 2015/16 or 17 so the backups would restore correctly

    That makes no sense.

    MLC has more endurance than TLC.

    Adding more layers to TLC doesn't improve endurance.

    That's 40nm TLC vs 15nm MLC... I'd vouch for Samsung's process, and vertically integrated product.

    can't even compete? this SSD is priced about the same with a 850 EVO SATA3, and a lot faster. try not to compare it with other SSD's that cost double. in reviews they put it up against the best so you can have an ideea where it sits.

    do you compare a Lamborghini with a VW Polo ?
  • lilmoe - Monday, February 20, 2017 - link

    You call 20$ a difference for NVMe drives? Really? Lambos cost 20 times more than Polos, the heck is wrong with you?

    "Hellfire" - for a disk drive? If I buy this, I'd be promoting stupid naming. There's a point in such things where the prospective customer is simply being insulted. Hard to define, but "I know it when I see it".
  • Murloc - Friday, February 10, 2017 - link

    Everybody has a naming scheme. What's wrong with copying names already used by weapons, for a company named patriot?

    Hellfire sounds stupid but other missile names aren't much better, or they're boring.

    Well, have a nap and then FIRE ZE MISSILES!!!
