The Samsung 960 EVO (1TB) Review
by Billy Tallis on November 15, 2016 10:00 AM ESTAnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.
We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.
The 960 EVO is substantially slower than both the 950 Pro and 960 Pro, but the 960 EVO is faster than the flagship SSDs from Toshiba and Intel.
The 960 EVO delivers average service times on par with other high-end PCIe SSDs, and is still slightly faster than any non-Samsung drive.
In the frequency of high-latency outliers, the 960 EVO is surpassed only by Samsung's 950 Pro and 960 Pro.
Despite using TLC NAND, the 960 EVO manages comparable power efficiency to the 960 Pro, putting it ahead of the fastest SATA drives but still drawing substantially more power than the most efficient SATA SSDs.

The pci.e speed only matters if you move with huge chunks of data such as a high res video editing. For pretty much anything else it offers nothing over sata ssd's.Flying Aardvark - Wednesday, November 16, 2016 - link
"The pci.e speed only matters if you move with huge chunks of data such as a high res video editing. For pretty much anything else it offers nothing over sata ssd's."In which case, you'd want something that won't throttle under heavy load like the Intel 750. Otherwise, the 600P makes more sense in M.2 form (if it remains cheaper than the 960 EVO).

While I agree that both SSD's are fantastic performers (I bought a 500GB 850 Evo), I don't think that your statement on buying other products is right. Some users cannot afford either, and a cheaper SSD would provide a nice uplift.Samus - Wednesday, November 16, 2016 - link
The 860 EVO is selling around 20% more than the 850 EVO did at launch. Just because its NVMe doesn't mean Samsung can milk that much more out of it, the Intel 600p is NVMe and it cost almost half the price. And...Intel. I get that Samsung has improved tremendously in SSD reliability but many of us still have a sour butthole from the 840 TLC drives they never really fixed and honestly, we're comparing Porsches to Ferraris here. Nobody is going to notice the difference between these drives is day-to-day tasks.close - Wednesday, November 16, 2016 - link
"And...Intel"Can't say I really agree with this "default" view since I happened to see the end-of-life behavior for some Intel SSD's. This was some years ago (4-5) so the experience might not be relevant now but for multiple SSDs when they got close to their end of life I just got a warning popup in Windows to back up my data. That's it. I foolishly made the assumption that I can just image the SSD to speed up the process only to realize after the reboot that the SSD controller just killed itself on shutdown.
This isn't the kind of behavior you expect from any data storage medium. The explanation was that Intel was trying to avoid data loss from the drive just failing due to wear. And they chose to mitigate this by triggering data loss by design choice.
While the price and performance may be good I still have to think twice (or more) when considering Intel SSDs.

@close: thank you for posting this. good to know!Samus - Thursday, November 17, 2016 - link
Wow interesting I've come across dozens of X25-M's and lowest health I've seen was 77% in Intel SSD Toolbox and that was a 300GB SSD320 in an exchange server. The MDB was over 100GBAscaris - Friday, December 16, 2016 - link
Have to agree; that's completely unacceptable behavior. Samsung's 840 Pro (I think it was) went way, way beyond its rated life in the TechReport test (over 1 petabyte) before finally giving up the ghost. If the Intel in question bricked itself based on published ratings, it could have cut its useful life in half. I don't know if that's how it did it... a better way (that it could feasibly have also used) would be to issue the warning when most or all of the overprovisioned spare cells have been deployed to replace those that have worn out (which ought to be a sure sign that all of the cells are close to the edge because of wear leveling)... but if anything, it should go read-only, not brick itself.DrunkenDonkey - Tuesday, November 15, 2016 - link
Billy Tallis, can you make a QD1 comparison graph alongside the mix of 1,2,4? Because average end user pretty much only cares for 4k QD1, RR, the mixed stat is more niche and not indicative. Thanks.Flying Aardvark - Wednesday, November 16, 2016 - link
Seconded. Reads like an ad otherwise.
