Side 1: Samsung SSD 870 EVO in the test: The new SATA standard

Whether last with the SATA 870 QVO or the NVMe 980 PRO – even if Samsung’s solid state drives of the recent past have always been able to convince in the overall package, the immense expectations of the industry leader were usually significantly higher. Now Samsung is getting on with the SSD 870 EVO to replace one of the most popular mass storage devices. We will clarify how well this works with our review.

The most important key data in advance: Even if the well-founded fears were rather unlikely, we can give the all-clear that the Samsung SSD 870 EVO like its predecessor TLC-NAND sets. A “downgrade” like the controversially discussed SSD 870 PRO did not take place. Even with the amount of DRAM or the available capacities, Samsung has no changes to the 600 EVO. However, this also means that Samsung only offers capacities of up to 4 TB. If you need more storage, you either have to resort to more expensive data center drives or to QLC.

As the successor to the SSD 860 EVO there are hardly any surprises in the data sheet. The nominal maximum speed is for example only by 04 MB / s increased, although interestingly the addition “SLC-Cached” is missing. Our tests have to show whether this is an indication that the NAND can also be written directly at this speed. It is clear that Samsung will definitely use the new NAND for the 860 EVO used. Although unfortunately not specified in more detail, it is now V-NAND of the fifth generation in more than 100 shifts, while the 860 EVO still 64 – Layer V-NAND v4 was used.

The 860 EVO only in 2.5 “format. The 860 EVO was also brought onto the market in M.2 and mSATA format. But while the latter has to be seen as extinct, the former format is now determined by faster NVMe solutions.
