Samsung has dominated the SSD marketplace for a really very long time, and each new client SSD mannequin the corporate introduces is noteworthy. The newest product to achieve the cabinets is the brand new vary of 870 EVO SSDs, constructing on a decade-long legacy of SATA SSDs. We have examined the 1 TB and Four TB fashions from this new product household.
Pushing for SATA
Samsung is without doubt one of the few corporations nonetheless placing important effort into SATA SSDs and releasing new client SATA fashions. As PC OEMs have overwhelmingly switched to utilizing NVMe SSDs in new methods, even on the smaller capacities, the shopper/client SATA SSD market now exists virtually solely for the sake of DIY system builders and aftermarket upgrades on older methods. Most main client SSD manufacturers have both stopped updating their SATA fashions, or determined to quietly replace elements with out the fanfare of a brand new mannequin launch. Then there are corporations creating odd-ball fashions, comparable to a 15.36 TB design. Either means, we do not get many new client SATA SSDs in for evaluation lately.
(It is price noting that the enterprise SATA SSD market has seen considerably extra in the best way of seen exercise, as a result of the longer product lifetimes in that market and the upper revenue margins give SATA SSDs extra of an extended tail of business relevance.)
Despite this market shift, Samsung remains to be targeted on a SATA product line, though even Samsung is displaying decreased curiosity in SATA. It took over six months from the discharge of the QLC-based 870 QVO for its TLC-based 870 EVO sibling to reach, and there is nonetheless no signal of an MLC-based 870 PRO mannequin (or every other MLC SSDs from Samsung primarily based on something newer than their 64-layer 3D NAND). Furthermore, the brand new 870 EVO now not caters to both mSATA and M.2 SATA type elements, focusing solely on 2.5-inch drives. The mSATA model of the 860 EVO disappeared from the market final yr, however the M.2 SATA model remains to be available and has tracked market value developments as a lot as Samsung’s drives ever do. It’s a little bit of a shock that they are dropping M.2 SATA this quickly given how lengthy Samsung supported mSATA.
Given the roughly three-year cadence Samsung has set for his or her SATA SSD updates, the 870 era might also be the final.

We are seeing the standard upgrades within the spec desk for the 870 EVO in comparison with the 860 EVO from 2018. The controller is now Samsung’s MKX, a minor iterative replace to the 860’s MJX. The NAND flash reminiscence is a extra important soar: the 870 EVO is utilizing Samsung’s 128-layer 3D TLC, first seen on the 980 PRO. More particularly, our 1TB and 4TB 870 EVO samples are utilizing the 512Gbit dies that had been launched on the 2TB 980 PRO, a mannequin that arrived a lot later than the smaller capacities constructed round 256Gbit dies. The previous Samsung 860 EVO launched with Samsung’s 64L 3D NAND, and so they seem to have ignored their 92L era with their TLC SATA drives.
The efficiency specs are similar to the 860 EVO. Almost all of these…
