AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.

AnandTech Storage Bench - Heavy (Data Rate)

On the Heavy test, the Plextor M8Pe can't compete with Samsung's MLC-based PCIe SSDs, but its average data rate is almost as high as the 1TB Samsung 960 EVO, and the 512GB OCZ RD400. The M8Pe is about 66% faster overall than the best SATA SSDs; a smaller margin than for The Destroyer but still substantial.

AnandTech Storage Bench - Heavy (Latency)

The average service time if the M8Pe is surprisingly slightly better when the test is run on a full drive than an empty drive. Either way, it doesn't deliver latencies as low as Samsung's PCIe SSDs, but it is close to the rest of the MLC-based PCIe SSDs.

AnandTech Storage Bench - Heavy (Latency)

The M8Pe has about twice as many high-latency outliers as the fastest PCIe SSDs, and the SATA-based Samsung 850 Pro is only a little worse off than the M8Pe.

AnandTech Storage Bench - Heavy (Power)

The power consumption of the M8Pe is again worse than any PCIe M.2 drive other than the much slower Intel SSD 600p.

    Conclusion page: the paragraph "The performance differences between the Plextor M8Pe and the Toshiba OCZ RD400..." is repeated. BRO DO YOU EVEN EDITOR?

    I think the problem may have been too much editor. My browser was getting really laggy and unresponsive while I was finishing up the article and rearranging things.

    Whoa there are still readers here? hah, I was cleaning out my bookmarks and saw anandtech. You realize all the talent left ages ago right? This site is dead. They're just riding on the name now...

    @Threnx - where do you go now since Anandtech is a shell of its former glory?
  • TemjinGold - Wednesday, December 14, 2016 - link

    So... it basically loses across the board to the EVO but they want to charge more for it?
  • Billy Tallis - Wednesday, December 14, 2016 - link

    Keep in mind that the 960 EVO results here are for the 1TB model, and that kind of capacity advantage usually brings some performance advantage, too. But yeah, once the 960 EVO is actually shipping in volume, a lot of prices will probably have to come down. Unless the 960 EVO price goes up.

    Prices for Samsung SSDs are rising due to the NAND shortage. If Plextor manages to resist this trend they might do well. After all most current workloads don't need anywhere near that kind of level of performance so a slight performance disadvantage is tolerable as long as it's reflected in the price.

    I wasn't aware of a NAND shortage. Do you happen to know the cause?
  • Samus - Wednesday, December 14, 2016 - link

    It's simply a supply and demand issue. Other causes are manufacturing process adjustments and lower yield issues often associated with transitioning to new processes.

    However, the shortage isn't as dire as 'close' makes it seem. Drive prices aren't necessarily increasing because of the shortage, but they aren't falling as they should be with the density improvements associated with TLC and widespread adoption of 3D VNAND. Samsung drives are increasing in price because vendors have noticed sharper demand for them than other drive, and I'm sure you can guess why based on this article alone...I'm not a Samsung fan, but they are currently the most balanced SSD products on the consumer market.

    Ah that makes sense. Thanks!
