Samsung 960 Evo full review
The Black Friday sales season is here! The best deals are often not on Amazon. The prices shown above are the best available now, though you may need to buy quickly as some deals will sell out.
This miniscule SSD comes in an M.2 form factor and uses NMVe (Non-Volatile Memory Express) technology - but don't let its size fool you, the Samsung 960 Evo packs a serious sequential read/write punch. Read on to see how the 960 Evo compares to SATA III-based SSDs and its brother, the 960 Pro. Also see: Best SSDs | Samsung 960 Pro 512GB review.
Note that there is now a newer model: read our review of the 970 Evo.
Samsung 960 Evo 1TB review: Price, competition and price per GB
The 960 Evo is cheaper than its counterpart: the 960 Pro. At £404.73 ($479.99 in the US) the 960 Evo is still expensive versus SATA III SSDs found in the market today - such as the Samsung 850 EVO 1TB at £285.98.
NVMe SSDs are still new to the market and their adoption rate has been relatively slow, mainly due to motherboard chipsets very slowly adopting the extreme speeds capable from a storage device.
Despite its high price tag, the 960 Evo 1TB only comes with a three-year warranty and guarantees 200 TBW (terabytes written). The 960 Pro on the other hand, offers 400 TBW and a five-year warranty. Read next: Best portable hard drives 2016.
When connected to our Windows 10 test rig, the 960 Evo displayed 931GB of usable storage. This results in a high £0.43 per GB which is double the cost of regular SATA III SSDs, but is considerably cheaper than the £0.65 per GB 960 Pro. Read next: How to build a PC.
Prices change on a daily basis, but these were correct at the time of each review:
Samsung 960 Evo 1TB review: Technology
NVMe technology has been around for some time, but it has taken time for consumers and most importantly board manufacturers to take it on seriously - in our case, our motherboard didn't feature an M.2 slot, meaning we had to get an adaptor for around £30 to test the SSD. (Note: make sure it's an NVMe adaptor, connects through PCIe and has an M.2 connector.)
The M.2 form factor is miniscule, at only 22.15x80.15x2.38mm, it definitely isn't a storage device you would associate with blistering fast speeds.
The 960 Evo uses Samsung's very own V-NAND technology and utilises a 2-bit MLC (multi-level cell) NAND to store data. The V-NAND technology found within the 960 Evo is the same technology which proved extremely popular on their SATA III SSDs (such as the 850 Evo).
We should mention that the 960 Evo 1TB features a Low Power DDR3 1TB Memory Cache. This gives it lots of headroom when transferring large files to and from the drive.
The 960 Evo, like the 960 Pro features AES 256-bit and TCG Opal 2.0 hardware encryption to protect your data from hackers - you'll have to enable this through software and through a UEFI-enabled BIOS. Samsung's magician software is free to download and also ideal for firmware updates.
If you're buying this SSD for a laptop, the 960 Evo consumes 5.7W when active and 0.4W when idle. Read next: Best NAS drives 2016.
Samsung 960 Evo 1TB review: Benchmark performance
We tested the 960 Evo using CrystalDiskMark and AS SSD benchmark, where just like the 960 Pro found interesting results, notably with AS SSD benchmark - where the 960 Evo under performed versus its SATA III counterparts.
Through CrystalDiskMark, the 960 Evo provides ridiculously fast sequential speeds with reads of 1717.8 MB/s and writes of 1729.8 MB/s. This does make it slower than the 960 Pro that hits 2048.8/1822.7 MB/s respectively.
However its 4Kb performance is below-average, with only 32.8 MB/s read and 50.2 MB/s write speeds, the 960 Evo even falls short of SATA III drives!
On the plus side, the 960 Evo offers ridiculously fast speeds in all of its sequential benchmarks, making SATA III drives look sluggish in comparison. The difference is further emphasised when compared to a traditional HDD, such as the 7200 RPM Seagate hard drive in our comparison.
Using the PCIe lane speeds found on motherboards, the 960 Evo is able to shine and will provide you fantastic read/write speeds if you're transferring large files back and forth.
As aforementioned, AS SSD benchmark was unable to correctly pick up the speeds of the 960 Evo, the same applied to the 960 Pro, where speeds were throttled by the benchmarking tool.
Look back at CrystalDiskMark, the 960 Evo yet again displays phenomenal sequential read/write speeds, but just like the 960 Pro falls short in its 4Kb tests.
In AS SSD's compression benchmark, we noticed small inconsistencies between the read and write speeds, but these results were surprisingly better than those found on the 960 Pro.
In its copy benchmark, the drive provided fantastic results, with some of the fastest access times and fastest speeds we have tested to this date.
Samsung 960 Evo 1TB review: Should I buy the Samsung 960 Evo?
The 960 Evo is very much like its brother, the 960 Pro - it provides ridiculously fast speeds, but unlike the Pro is more affordable, making it a better buy for most consumers.
Granted, if you're extremely serious and worried about its 4Kb read/write speeds, then the Pro might be the better purchase - especially given the better warranty and TBW data guarantee provided on the Pro drive.
If you're looking for a drive that's ridiculously fast, then the 960 Evo is still our recommendation. Of course cost does come into the equation and it's more expensive than conventional SATA III drives out in the market today - but that's the price you're going to have to pay if you want those premium speeds.
If you're not too fussed about speeds, then we would recommend holding off the purchase of NVMe drives in general - at least until they drop in price, just like SATA III SSDs did in the last eight years.
Let us know in the comments below if you feel NVMe is worth the investment or if you'll be holding out for prices to drop!
