It reads random data 38% faster than the previous 860 EVO and boasts 30% more performance overall. The 870 EVO is a candidate to become Samsung’s best-selling SSD. 250 GB cost 47 euros.
Samsung has unveiled a new 2.5 “SATA SSD from its cheapest and best-known series, the 870 EVO, which returns to a classic V-NAND TLC configuration, i.e. three bits per cell, after the launch of the 870 QVO with QLC technology, four bits per cell, arrived in the summer of 2020.
On paper, a QLC SSD is as fast as a TLC in sequential data reading, but the latter is a bit faster in writing; just as it is more resistant to read/write cycles, but has a reduced capacity from three bits per cell against the four per cell of QLC.
Performance improved by 30%
The comparison to be made for the launch of the 870 EVO, however, is with the previous generation of the 860 EVO. Samsung has given the 870 EVO controller and V-NAND flashes the latest iteration of its technology, allowing it to achieve 6 Gb / s sequential SATA 3 read and write speeds of 560 and 530 MB / s, respectively. s.
For the buffer, it uses a variable SLC that is paired with Intelligent TurboWrite technology capable of maintaining performance at peak levels. Compared to the 860 EVO, the new 870 EVO has a 38% better random data reading speed. Complessivamente, however, performance is increased by 30%. The 4 TB model, in addition to a 5-year warranty, also has a value of 2,400 TBW, that is, 2,400 Terabytes guaranteed in writing before showing any possible malfunction.
The 870 EVO is compatible with devices that support the Windows Modern Standby feature for power saving, which has been available since Windows 8.
Samsung has announced the Italian price only for the 250 GB cut of the 870 EVO, which is 46.99 euros. In the catalog, however, there are also cuts of 500 GB, 1 TB, 2 TB, and 4 TB.
