The Plextor M8Pe (512GB) SSD Review
by Billy Tallis on December 14, 2016 9:00 AM ESTAnandTech 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.
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.
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.
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.
The power consumption of the M8Pe is again worse than any PCIe M.2 drive other than the much slower Intel SSD 600p.

Nand shortages ... L o L ...So much fake news. So much WoW !

"The M8Pe's consistency scores are quite low, indicating that it lacks the tight regulation of Samsung and Intel's best drives that have similar average performance."This is rather misleading and shows again the little alue your consistency metric brings.
In the case of the Plextor, it has a well defined floor around 25kops and bursts of speed above that. Although it makes it inconsistent, it has a high minimum.
This would be like complaining that a core i7 with turbo boost is inconsistent, because although it has a 4GHz floor, it sometimes boosts to 4.5GHz when possible and as such is worse than a constant i3 at 2GHz...

Billy is saying just that in the next paragraph. If you read both together it's like "graph A indicates... however, graph B show that it's really..."helvete - Wednesday, January 11, 2017 - link
Who would buy 1TB variant w/ a heatsink for $650 when one can take 1TB bare plus 128GB w/ a heatsink for $616 ($516 + $100). Then transfer the heatsink and the drive is still $34 cheaper and the 128GB remains remains as a free bonus:-)
