Samsung 870 QVO 2TB V-NAND SSD evaluation
Simply over 18 months after it was launched, the 860 QVO is making approach for the 870 QVO. The second iteration of Samsung’s common price range line has upped the ante with the introduction of an 8TB strong state drive, the primary time we’ve seen this capability hit mainstream.
The drive is out there in 4 variations: 1TB ($129.99), 2TB ($249.99), 4TB ($499.99) and eventually 8TB ($899.99). It’s value noting that purchasing a pair of 2TB SSD prices roughly the identical because the 4TB one.
The 870 QVO makes use of Samsung’s second era 4-bit MLC V-NAND paired with the brand new MKX controller. The 2TB mannequin we examined as we speak has a 2GB LPDDR4 which is used as DRAM cache reminiscence. The reminiscence dimension grows proportionally with the SSD capability. As anticipated, the machine runs on a SATA interface which is considerably of a disappointment and limits the anticipated efficiency of the product.
Sadly, regardless of our greatest efforts, we couldn’t pry the case open to verify the motherboard. It’s value noting that the drive weighs in at 46g which is considerably lighter than the 62g of the 860 QVO. What it means is that the SSD is prone to be principally empty area with the two.5-inch enclosure wanted for compatibility with current methods.
The software program
The 870 QVO ships with Samsung’s newest iteration of its Magician SSD toolbox, a set of helpful purposes that means that you can replace the drive’s firmware, allow encryption choices, monitor the well being of the SSD and extra. Samsung additionally affords a Information Migration software program, which allows the person to clone over knowledge from an current drive to the brand new SSD by way of a “customized cloning” function.
Notice that the drive additionally helps a variety of safety features like AES 256-bit (Full Disk Encryption), TCG/Opal V2.Zero and Encrypted Drive (IEEE1667).
The Samsung SSD 870 QVO is rated at 560MBps and 530MBps respectively on sequential learn and write. Samsung caveats the latter quantity by including that the numbers are based mostly on its Clever TurboWrite expertise; the latter is a hard and fast quantity of SLC buffer (42GB within the 1TB mannequin, 78GB on the others).
Right here’s how the Samsung SSD 870 QVO carried out in our suite of benchmark checks:
CrystalDiskMark: 561.12MBps (learn); 530.2MBps (write)
Atto: 537MBps (learn, 256mb); 509MBps (write, 256mb)
AS SSD: 502.25MBps (seq learn); 483.7MBps (seq write)
AJA: 486MBps (learn) ; 466MBps (write)
As soon as the buffer is full or if the SSD has lower than a certain quantity of free storage, Clever TurboWrite is not going to work and sequential write efficiency can fall to as little as 80MBps for the 1TB mannequin and 160MBps for the larger capacities. Random reads and writes (QD1) are rated at 11Okay IOPS (a 13% enchancment on the 860 QVO) and 35Okay IOPS.
The drive comes with a 3 12 months guarantee and has an endurance of 0.33 drive writes per per day (that’s 720TB in complete) which is analogous to the 860 QVO.
As for the benchmarks, no shock there: the 870 QVO performs admirably for what it’s, a SATA-based SSD. It does hit the quoted numbers beneath CrystalDiskMark with sequential learn speeds of 561MBps/530MBps respectively in learn/write utilizing our take a look at system (the Chuwi GBox). Numbers for AJA, ATTO and AS SSD benchmarks have been equally spectacular however keep in mind that it is a fraction of what PCIe NVMe fashions can obtain.
There’s two sides to this: First, the 8TB model. Surprisingly, there’s competitors at this capability however not from the same old suspects (Sandisk, Seagate, Sabrent or Kioxia). No, the Micron 5210 ION SSD is an enterprise strong state drive which has been round for practically two years and has, till now, supplied among the least expensive costs per TB costs on excessive capability SSD.
On the time of writing, its highest capability (7.68TB) could be bought for $879 from Amazon, which is barely costlier per TB in comparison with Samsung’s 8TB mannequin ($114.45 vs $112.50). Additionally it is slower than its rival however has an extended guarantee (5 years), a far, FAR greater DWPD (drive write per day) at 0.eight and a Complete Byte Written that exceeds 1.1PB (that’s Petabyte).
Micron launched it as a substitute for giant 10Okay RPM onerous disk drives that populate knowledge facilities and as such is geared in direction of these use instances. No surprises right here that it makes use of Micron’s personal 3D QLC NAND.
The competitors on the decrease capability factors is even fiercer; At 4TB, Samsung’s personal 860 QVO, in no way a slouch, could be had for $449, Sandisk’s Extremely, for $449.99 – in each instances 10% reductions – whereas WD Blue hits $527.46 however makes use of TLC somewhat than QLC. At 1TB and 2TB, Samsung faces extra competitors and is prone to be at an obstacle as quicker PCIe NVMe fashions come down in value quickly.
We’re excited in regards to the 8TB model of the Samsung SSD 870 QVO, much less so in regards to the others. Given the present development, we are able to count on the subsequent era, in all probability referred to as the Samsung SSD 880 QVO to achieve 16TB in about two years, which might put it on equal footing with onerous disk drives, that are presently at this capability and most unlikely to develop nicely past that over the subsequent 24 months.
For the opposite storage tiers although, there’s hardly something value getting enthusiastic about given the small efficiency acquire over the 860 QVO. Efficiency is in step with what is anticipated of a SATA drive and we’ve reached a degree the place a PCIe NVMe drive, which is able to reaching much better numbers doesn’t price much more than this one (and is probably going to make use of non-QLC components).
