By analyzing the above-mentioned features, we can conclude that PRO leads.
Differnces in their Interface:
Both competitors support all three generations of SATA or Serial ATA interface.
SATA 1.5Gb/s is the first generation that communicates at an innate transfer rate of 1500Mb/s.
The second generation of the SATA interface runs at a bandwidth throughput of 300MB/s and the third generation of the SATA at 600MB/s enables faster transfers of short gusts of data from drive caches
| Parameter | 860 PRO | 870 QVO |
| SATA 6Gb/s | Yes | Yes |
| SATA 3Gb/s | Yes | Yes |
| SATA 1.5Gb/s | Yes | Yes |
What’s different in their Design & Hardware?
Samsung 860 PRO has a black shiny and attractive background with white lustrous dots, with Samsung written in the center, along with a Meta description Solid State Drive in white, and a red square just below it.
Samsung QVO has a silver shiny background with Samsung written in the center along with a Meta description Solid State Drive in black and a black square just below it.
Both SSD has a slimmer look and smarter body shape and dimension and is rectangular.
Samsung QVO is lighter in weight than its contender. Hence, it wins this contest for being more compact and lighter in mass.
Temperature greatly affects the reliability of the SSD. Both contenders are rated reliable for operating within a temperature range of 0ºC up to 70ºC.
The temperature that a device can tolerate when it’s in the non-operating mode is called the non-operating temperature. Non-operating temperatures for the SSDs range from -45°C to 85°C.
The operating and non-operating temperatures of both SSD are the same and fall in the ideal range of SSD.
| Parameter | 860 PRO | 870 QVO | |
| Dimension in inches (W x H x D) | 3.9 x 2.75 x 0.27 | 3.9 x 2.75 x 0.27 | |
| Weight, g | 4TB = 62 | 4TB = 54 | |
| Form Factor, inches | 2.5 | 2.5 |
How much “Terabytes Written” Both have?
TBW short for Terabytes Written is the overall amount of terabytes of data that an SSD can write in its lifetime.
A drive with a higher TBW will comparatively ensure a greater life span.
Samsung QVO has a relatively higher amount of TBW than its opponent hence, it has a greater lifespan.
| Parameter | 860 PRO | 870 QVO |
| TBW | 1440 | 2880 |
Power Consumption of both:
Samsung QVO consumes less power in an idle state as compared to its competitor.
When the device is in sleep mode both consume equivalent power.
Hence it wins the race for consuming less power which will eventually result in lower electricity bills and will be a more cost-efficient choice comparatively.
| Power Consumption | 860 PRO (4TB) | 870 QVO (4TB) |
| Idle Average (mW) | 40 | 35 |
| Device sleep (mW) | 7 | 7 |
What’s their Storage Memory?
Both competitors use the cutting-edge V-NAND technology short for Vertical NAND technology. As the name implies, it is a 3D-cell layer-stacking technology in which cells are vertically piled up 3-dimensionally to make less use of the available space on the SSD in every NAND chip.
Both are Multi-level cell (MLC) that stores multiple bits per cell. MLC has a relatively higher data density than SLC which stores single bits per cell so can therefore be produced in larger capacities.
The 860 PRO supports 2bit MLC (Multi-level cell) that stores two bits per cell while QVO supports 4bit MLC that stores 4 bits per cell.
Therefore, 870 QVO takes the lead for superior storage capacity of storing 4 bits per cell.
| Parameter | 860 PRO | 870 QVO |
| NAND Flash Memory | Samsung V-NAND 2bit MLC | Samsung 4bit MLC V-NAND |
Which has better Sequential Read/Write Speed?
Two comparative measures to determine how fast a drive can read and write the data in a fixed order is the sequential read and write speed.
Sequential read speed measures how rapidly huge files can be read from a drive.
Write speed measures how quickly a file can be written onto the drive.
Both competitors have an equivalent sequential read and write speed. So the contest ended up in a stalemate.
| Parameter | 860 PRO | 870 QVO |
| Sequential read (Mb/s) | 560 | 560 |
| Sequential write (Mb/s) | 530 | 530 |
What these devices can give in terms of their Storage Capacities?
Samsung PRO beats its opponent with a groundbreaking storage capacity of up to 8TB.
While its contender supports a storage capacity of up to 4TB.
When talking about versatility, PRO version offers more flexibility in the product range. It has 5 sizes available while its contender has only 4 sizes.
Hence, QVO variant dominates for having a massive storage capacity while PRO dominates for versatility in products.
| Specification | 860 PRO | 870 QVO |
| Capacity | 256GB, 512GB, 1TB, 2TB, 4TB | 1TB, 2TB, 4TB, 8TB |
Warranty they give out:
Although both competitors are manufactured by the same company, their warranty period differs from one another.
Samsung offers an extended warranty period of 5 years for PRO while only 3 years for QVO.
Hence, PRO takes the lead here for an extended warranty period.
