Fantastic m2 2TB from intel. For ordinary/high end consumers this is a good buy performance vs price and storage capacity. Note..: that if you copy a huge file such as steam with 800gb of games to this m2 then in the start the transfer speed is huge, but then it drop after a while... it have something to do with cache and many more advanced things that i cannot explain... HOWEVER how often do you really transfer example 800GB from one drive to another ?? .. well litterly never.. so does this really matter.... NO For ordinary and high end usage on a consumer pc this m2 is really good and have high speeds in gaming, and example runs windows 10 perfect and fast. I can higly recommend this m2 for the lower price and its have great performance for your games and software ect. YES its a bit slower than the populare and expensive samsung m2's but you will actual barly notise it... ( i know since i have a 256gb samsung 860 that run with 3200mb/s speed vs the intels 1900m/s in benchmark test... But in games and loading times of windows i dont really see any important difference ). The thing is when you compare hardware and such, then yes maybe it can transfer some data faster, but when it come down to "reality" and example loading a game or running software then the super fast samsung and the slower intel m2 actual perform much the same. I highly recommend this intel m2, its like 4-5 times faster than an SSD, and it operate at about 1900mb/s at max speed. For gaming and ordinary tast this is fantastic and you get 2tb of data and speed for like 40% cheaper than other m2's out there. whats not to like. ;-)

Priced at 200 USD, this 2TB NVMe TLC SSD offers pretty much bigger storage capacity and faster than SATA SSD while being priced lower than nearly every 2TB SSD (mostly SATA) on the market. In my thought, this SSD is pure bargain to get if you choose to opt for high-capacity SSD instead of high-capacity HDD for reliability or speed reasons.

Good speed, even faster with small files than samsung 960 evo. It is the cheapest 2TB SSD in Lithuania. So why buy sata ssd when you can have this for lower price. Intel provides 5 year waranty for Intel 660p ssd.


11 months ago.

Pretty much offered the highest value for capacity ever SSD. Has a fast NVMe interface and very high (2TB) capacity for like 200 USD. But because majority of this SSD's speed relies on caching, you may experience HDD-like read/write speed when the file transfer exceeds cache size.
