Samsung 870 EVO 2.5″ SSD with up to 4TB storage capacity appears online
Samsung seems to be working on a new 2.5″ SSD with SATA interface. According to WinFuture, the 870 EVO has appeared at various retailers and shows great similarities with the current 860 EVO. It is not yet known when the SSD will be available.
The SSD would have appeared at web shops in Europe and the US, writes German tech website WinFuture, which more often publish information about unannounced products. It would be a 2.5″ SSD with SATA interface, which should follow the current 2.5″ variant of the Samsung 860 EVO. It is not yet clear whether the 870 EVO will also be available in other form factors at a later date. For example, previous SSDs in the 800 series were also available as an mSATA variant. The Samsung 860 and 850 EVO were also available as SATA SSDs in M.2 form factor.

The specifications of the 870 EVO also show great similarities with those of the current 860 EVO. The sequential read and write speeds of the new variant are both 10MB/s higher, but the storage capacity of up to 4TB and the total bytes written of 2400TB remain the same. The random read and write speeds are not yet known.
The 870 EVO is expected to use tlc-nand, just like the current 860 EVO. Samsung previously came with 870 QVO SSDs, which use qlc memory and come with a maximum of 8TB storage capacity. According to WinFuture, the 870 EVO SSDs cost between 70 and 450 euros, depending on the capacity. It is not yet clear when Samsung will announce the SSD series.
