I have to admit that I was not expecting so much from Addlink's S70 SSD. I had never heard of the company before, and a 1 TB NVMe SSD at a price as low as $ 120 raises all the red flags I know about performance.
Well, wave me and tell me that I am ridiculous if the S70 did not clutter other budget records, and many more expensive models in our tests, easily deserving a Editor's Choice. The market has become very interesting.
This review is part of our best-of-breed SSD tour. Check out this story for information on competing products and how we performed the tests.
Specifications and design
There is not much to say about the design of the S70, apart from its average M.2 NVMe SSD, which is in 2280 format (22mm wide, 80mm long). It is PCIe 3.0 x4 (using four channels) and uses a Phison PS5012 controller and a 64-layer TLC NAND (3-level / 3-bit cell). This turns out to be very good.
The S70 is available in four versions: the tested 1TB version ($ 120 currently on Amazon), a 256GB model ($ 40 currently on Amazon)), a 512 GB model (currently $ 67 on Amazon), and a 2TB model (currently $ 269 on Amazon). Yes, you pay a little more per gigabyte for the maximum capacity, but it's still damn cheap.
Performance
In synthetic benchmarks, the S70 gave the best records I tested for money. The fact that it slows down after exhausting the cache to a little less than 1 Gbit / s in sustained writing leaves it slightly behind. But only a few drives last faster than that, and I would hardly call this lazy rate.
The S70 is a very fast drive, and you'd be hard-pressed to tell the difference between the WD SN750 Black NVMe and the Samsung 970 Pro that I'm comparing it to.
IDGAlthough CrystalDiskMark does not have the reputation of beating the world, the number of AddLink S70 is not far from reality. The longer bars are better.
CrystalDiskMark figures from the S70, shown above (gold bars), measure sustained throughput with relatively small amounts of data (1 MB). The results for Addlink are stellar. The reader is not quite up to his more expensive competitors in real world copies, as shown below, but that's certainly about it.
IDGSlow down to just under 1GB / s in long sustained writing and other realities: the S70 can not compete with the Samsung 970 Pro, or even with the WD SN750 Black, but its price is quite close . The shorter bars are better.
The AS SSD proved a real blow to the S70, which beat even the mighty Samsung 970 Pro in two tries.
IDGThe SSD SS also has good things to say about the S70, although the real-world performance is not as good. Given the price, we do not care. The longer bars are better.
Performance is just not a problem with the S70, as with some older low-cost drives, but fortunately the days when NVMe drives were running at a lower speed than SATA when the cache was exhausted seemed old.
My only disadvantage with AddLink S70 is that the service and support are unknown quantities for me at the moment. I have had no relationship with the company, so I just can not say, although the five-year warranty lasts two years longer than what you typically see in the lower segment of the market. TBW (TeraBytes Written – the total amount of data that a company is willing to guarantee can be written on the reader). The nominal values of 350/600/1200/2000 for 256 GB / 512 GB / 1 TB / 2 TB drives are, respectively, quite high. as well as.
A difficult business to let through
I'm sure the prices of other readers will drop soon and suppliers will not be happy with them, given the already thin margins in the SSD market. But the sellers' pain is your joy and, as things stand, you can save $ 30 or more with the AddLink S70 without losing performance. Even if the prices were equivalent to those of the competition, I would recommend it. I consider the S70 as a very good introduction to AddLink.
