Samsung SSD 870 QVO evaluate: Stupendous 8TB capacity in a SATA SSD


The Samsung 870 QVO (‘Q’ as in in 4-little bit QLC), is our initial seem at a generate that will eventually ship with a whopping 8TB of NAND on board. Announced Tuesday, this is the new major potential available, superseding a however-new flock of 4TB types. Samsung sent us the 2TB variation for screening. It’s a terrific daily performer however, when you run out of cache (which shouldn’t be usually), write speed falls off greatly.

Specs and pricing

A standard 2.5-inch SATA 6Gbps SSD, the 870 QVO is at this time available in $130/1TB, $250/2TB (analyzed), and $500/4TB flavors. The 8TB product will be offered in August for $900. That is significantly cheaper than the substantial-capability 4TB OWC Aura P12 and 8TB Sabrent Rocket Q NVMe drives we not long ago included, and a far higher savings delta than we ordinarily see in between NVMe and SATA. 


Samsung’s 870 QVO is a definite advancement on the more mature 860 QVO, and it delivers great every day general performance. 

Samsung utilizes its personal MKX controller, and there is 1GB of DRAM cache for each and every 1TB of 96-layer, QLC (Quad-Degree Cell/4-little bit) stacked/layered/3D NAND on board. The drives seemingly allocate about 4.5 per cent of the NAND as SLC cache, if our checks with the 2TB drive are indicative.

SLC cache is MLC/TLC/QLC taken care of as SLC by creating only a person little bit rather of four, or if you prefer, on/off somewhat than just one of 16 attainable states. This is considerably, significantly quicker operation, as there is minimal to no mistake-examining required. The contents of the SLC cache are later on transferred to non-cache NAND.

The 870 QVO is warrantied for 3 many years, and is rated for 360TBW (TeraBytes Published) for every 1TB of potential. Samsung bundles its Magician software package, which offers regulate of overprovisioning (the amount of money of NAND established apart for substitute of dead cells), safe erase, and diagnostics. 


Initial, the good information about the 870 QVO’s performance—and in reality, excellent news is all the average person will experience. CrystalDiskMark 6 calculated the travel as matching the velocity of the competitors. Most SATA SSDs presently bump up towards the bus’s 6Gbps bandwidth limitation—hence, the virtually similar scores.

CrystalDiskMark 6 does not reveal a large amount of change in performance involving the drives proven. Largely for the reason that modern SSD capabilities mostly exceed the bandwidth of the SATA bus.

In the true-world 48GB transfer exams, the 2TB 870 QVO enhanced more than its older 860 QVO sibling. On the other hand, the 860 QVO we examined was a 1TB travel that ran out of cache at about the 45GB mark (I talked about the 4.5 percent cache), dropping to 75MBps for the last leg of the race.

With 48GB facts sets, the 2TB 870 QVO is a match for Seagate’s Barracuda SSD. The 1TB variation probable would’ve run out of cache just before the end of these transfers and turned in a more time time in the 48GB solitary file generate. Shorter bars are far better. 

The 1TB 870 QVO would no question have operate out about the similar time, but it in all probability continue to would have turned in a slightly speedier rating than the 860 QVO for the reason that of its quicker create amount, off cache.
