Samsung 860 EVO Solid State Drive

Have installed 5 of these now in different computers & laptops to replace magnetic drives. All working well and have made a huge improvement to Windows startup times. Programs load 5-6 times faster than before. Overall a great product!

This SSD is one of the best and reliable SSD in its category. Its read-write speed is still great (R - 545MB/s, W - 496MB/s) if compared to modern SSDs. Booting OS and loading of applications have become much faster than before (Avg. boot time - 5s). If I talk about gaming performance, it only speeds up the load up, performance-wise gain like increase in FPS is minimal (completely dependent on CPU and GPU). The Samsung Data Migration software provides a seamless data transfer to migrate data from the old drive to the new drive and the Samsung Magician software is a great monitoring + tuning app, you can tweak some parameters to improve its performance. The SSD (1 TB) has a whopping 600TBW lifetime, which means it will survive 600 TB of writing or more, i.e., massive. Overall, it's a great buy for me. If you have an SSD in mind, go for the EVO series (or PRO series, if you have that budget). P.S. - Avoid the QVO series, not much durable in terms of lifetime.

Produto muito bom, rápido e confiável. Embora um pouco mais caro que os modelos QVO mais recente, vale a pena pois dobra o número de operações de leitura/escrita, ampliando a vida útil do dispositivo além da garantia de 5 anos. Se comparado aos discos mecânicos (HDD, com motor) a velocidade de acesso é notoriamente maior. Em suma é uma boa opção para melhorar desempenho a um custo razoável. Outra dica interessante é ampliar a quantidade de memória RAM. Dependendo do perfil de uso recomendo 16GB, a combinação RAM/SSD é fundamental para um computador rápido, naturalmente depende do processador e canais de comunicação da placa-mãe (e qualidade).

Es ist meine zweite SSD 860 EVO 1 TB 2,5'', mit der ich zur vollsten Zufriedenheit arbeite: zuverlässig, schnell, fehlerfrei. Ein gutes Preus-Leustungsverhältnis!

Excellent all-around SSD for your average consumer. It has a very large endurance rating in terms of terabytes written. The 1TB version is rated for 600 terabytes written over it's lifetime. If you write 50 gigabytes per day you would take 32 years to reach the 600 terabyte write rating. An average consumer will not be writing 50 gb per day. Normal operating system activities will use at least half a gigabyte per day, sometimes as much as 5 gb per day. Your OS is constantly writing stuff to the disc as you're doing stuff. If you're someone who downloads a lot of movies/tv shows or programs then you might see up to 20 to 30 gb per day of writes. The point though is even if you're downloading/installing tonnes of programs or videos constantly you'd really struggle to reach 600 terabytes written before a conventional hard drive would be expected to fail due to a failure in it's moving parts. So unless you plan on using this for a server application where you can expect to be writing more than 0.5 to 1 terabyte e per day this drive will be more than enough. The drive itself pretty much saturates the SATA III connection, which has a maximum bandwidth of 600 megabytes per second. Sequential read speeds are over 500 megabytes per second for pretty much all file sizes/queue depth's. Sequential write speeds for small files will be over 500 megabytes per second typically. This SSD has a 'turbowrite cache', which is a higher speed SLC flash memory. I couldn't pin down how large the cache is on the 860 EVO 1TB; but I believe it's about 60gb. For the first 60 gigabytes of writing the drive will use the SLC cache and write speeds will be higher than they would otherwise be. When that cache runs out the drive switches to using it's normal TLC flash memory, which is a slower but cheaper type of memory (it's what makes up the drives storage capacity). Here's where things get complicated though. For larger drives like the 1TB model the larger number of flash modules in the drive means that the drive can write to more modules at once, and hence it's write speeds are faster. As a result you don't see a performance reduction when you switch from the SLC cache to the main TLC memory in terms of write speed when we're talking about the 1TB versions or larger. For the 500 gigabyte version or the 250 gigabyte version however we do see a significant write speed reduction when the turbowrite SLC cache runs out. In practice this means that the 1TB model can sustain about 450 megabytes per second of write speed no matter how big the file you're writing is. The 500gb model however starts at 450 megabytes per second but after it's written about 60 gigabytes (size of the SLC cache) the write speeds go down significantly. They drop to about 270 megabytes per second. To be fair most people won't need to write more than 60 gigabytes at once, but it's still a drawback of the smaller sizes. I should also mention that the 860 EVO for the 1TB model has 1 gigabyte of DDR4 RAM which the controller uses to decrease access times by keeping a map of where the data is being stored. This is part of the wear leveling algorithms to ensure that no flash cells degrade faster than the others.
