The Intel SSD 760p 512GB Review: Mainstream NVMe Done Right
by Billy Tallis on January 23, 2018 11:30 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. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.
The average data rate of the Intel SSD 760p on the Heavy test makes it clear that the 760p is not a high-end NVMe drive, but it does perform much better than SATA SSDs and previous low-end NVMe SSDs. The 760p also handles being full relatively well, so its SLC caching strategy seems well done.
The average and 99th percentile latency scores of the 760p aren't great, but they're still a big improvement over most earlier low-end NVMe SSDs. The 99th percentile latency has more room for improvement, since it is no better than a good SATA SSD.
The average read latencies of the Intel SSD 760p on the Heavy test are not quite as good as a high-end NVMe SSD but are definitely close enough for a product this cheap. The average write latencies are more in line with some of the better previous budget NVMe SSDs, and are close to the level of SATA SSDs.
The 99th percentile read latencies from the Intel 760p don't particularly stand out, and are reasonable for this product segment. The 99th percentile write latency scores are rather high, but not to egregiously like the Intel SSD 600p and a similar ADATA drive.
As with The Destroyer, the Intel SSD 760p shows very good power efficiency by NVMe standards, but the SATA drives and the Toshiba XG5 show that there's still room for much improvement.

Make sense especially with their own fab, they no longer need Micron to supply, but these chips are older generation, so they probably realize that future generations are not necessaryilt24 - Tuesday, January 23, 2018 - link
Intel converted a factory in China from making chipsets to making 3D-NAND a couple of years ago, then a couple of weeks ago Intel and Micron announced they would stop working together on 3DNAND once their 3rd generation was released ~2019. They said they would continue to collaborate on their 3DXpoint memory.Currently it isn't clear if all of Intel's supply comes from the Intel factory or if they are still getting any from the Micron fabs. Independent of where the flash comes from, it will have the Intel logo since they just get wafers from Micron and package it themselves.

Your pricing for the the Samsung 960 PRO are way off. You have prices for the 512GB in the 256GB column. 1TB for the 512GB, and 2Tb for the 1TB.Billy Tallis - Tuesday, January 23, 2018 - link
Fixed. Thanks!lux44 - Tuesday, January 23, 2018 - link
I guess post-Meltdown/Spectre benchmarking is in the pipeline, as IO-benchmarks should show a large drop... It definitely will make Core8 benchmarks a lot more interesting. I wish you all good luck in getting to the bottom of the things regarding performance impact, we count on you!tuxRoller - Tuesday, January 23, 2018 - link
Not as bad as was once thought.https://www.phoronix.com/scan.php?page=article&...
Ignoring the XFS results (just that they are using cfq means the fs is starting the fight with one arm, and most of a leg, disabled) it looks like 5% or less (except for the compile benchmark which caused one fs to drop 15%)

Given recent news about Intel microcode update recall and Linus's rants about unacceptable kernel updates, I think the actual Spectre mitigation impact is unknown, at least under Linux. I doubt it's larger than 15%, but we'll see.Jhlot - Tuesday, January 23, 2018 - link
Bummer, still significantly outpaced by the 960 EVO which was released more than a year ago.msabercr - Tuesday, January 23, 2018 - link
Dang it, this VW Beetle is nowhere near as fast as my 911 turbo.shabby - Tuesday, January 23, 2018 - link
Price is close enough that it should be.
