The Samsung 870 QVO in its 2.5” SATA 6 guise has been around for a while. It is not a replacement for the 860 series but a new Gen 2 design. It now has an 8TB model.
In fact, there are a few Samsung SSD 2/5” SATA 3/6 for 3/6Gbps models. Note specs are for the largest capacity.
| Capacity | Speed | RAM Cache LPDDR4 | Controller | Warranty | |
| 870 | |||||
| EVO | 250/500GB 1/2/4TB | 3bit MLC 38% faster than 860 EVO 560/530MBps | 4GB (4TB) 2GB (2TB) 1GB (1TB) 512MB (250/500GB) | MKX | 5-years or 2,400TBW (4TB) 1,200TBW (2TB) 600TBW (1TB) 300TBW (500GB) 150TBW (250GB) |

| EV0 | 250/500GB 2/4TB | 3bit MLC 550/520MBps | As per 870 EVO | MJX | 5-years or 2,400 TBW |
| PRO | 256/512 1/2/4TB | 2bit MLC 560/530MBps | Max 4GB | MJX | 5-years or 4800TBW |
| QVO | 1/2/4TB | 4bit MLC 560/530MBps | As per 870 QVO | MJX | 3-years or 1,440 TBW |
Samsung’s “Magician” software manages SSD’s metrics, AES 256-bit Encryption, WWN (world wide name), SMART (detects possible drive failure before it happens), GC (a garbage collection algorithm) and device sleep mode support.
As for speed – 3bit is slightly faster, but you would not know unless you fill the RAM buffer. Similarly, the MKX controller is marginally quicker but does not overly affect results.
In conclusion – Samsung 870 EVO focuses on performance and is best for everyday use. Samsung 870 QVO focuses on best price per GB, albeit at slightly lower performance levels for large files.
