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.

I think they're trying to say the performance isn't great. Failing means we don't get to see the performance numbers.Dave Null - Tuesday, November 15, 2016 - link
This is indeed frustrating. I was expecting the 960 Pro drives I preordered to arrive last week. Now Amazon is reporting January.Something major must have happened for Samsung to miss its release date so badly, but nobody is reporting it.

I went with the 600P 1TB instead.. had it for 2 weeks now.. I love it. Being M.2 I didn't buy it for heavy workloads anyway so it won't throttle. But if I needed performance I'd go with the Intel 750 instead of what I got.Phattio - Wednesday, November 16, 2016 - link
my 960 Pro 512GB arrives today. ordered from best buy online.Kristian Vättö - Thursday, November 17, 2016 - link
There is a simple explanation: NAND shortage.XabanakFanatik - Thursday, November 17, 2016 - link
Of course! I'm glad you had an article about it. Oh, wait.I'm fairly certain that people need to know that despite your reviews coming out on time that they won't be able to buy the products for months.

Interesting to see the rate at which these continue to progress, and I'm glad Samsung continues to ramp performance aggressively. One thing I wish you could find some way to integrate is at least a summary of reliability features like how a drive handles power loss, and (depending on feasibility if you are mainly testing short-term loaners) maybe some followup a few months down the line with longer term performance/reliability observations. While Samsung has long been at or near the pinnacle of out-of-box raw performance, they've also had a history of playing a bit fast and loose with reliability and support, and I think that deserves some sort of recognition. I have a lot of Intel 730s that replaced or were chosen over Samsung drives of the time after a number of poor experiences with the long term usage 840 series for example, and while the 840s were superior in many respects on paper and Day 1, by Day 100+ and under stress they developed issues that were not immediately apparent.Also, a small typo on the final page, looks like at least one of the $/GB (the 750@1TB) isn't right.

I am working on some longer-term data and performance retention testing, but the amount of extra equipment that requires means not many drives will get that treatment. Unexpected power loss testing might be more feasible, but for the near future the testbed is too busy for me to add something like this to the routine.The Intel 750 doesn't fit conveniently in the price comparison chart because of its unusual capacities. The prices listed are for the 400GB and 1.2TB models, and the 800GB model isn't listed in the table.

Speaking of long-term data retention......If I had 2 SSD's, one unplugged and stored in a closet and one plugged in with power on but idle and unused, would the one plugged in retain data longer even though it is unused????

Yes. There is wear leveling and data refresh in modern SSDs (840/Evo being the exception with cell band drift)
