The numbers we saw out of the overall PCMark 10 score are quite promising, putting this SATA drive in the same leagues as M.2 PCI Express 3.0 NVMe drives like the ADATA Spectrix S40G or Crucial P2.As for the PCMark 10 Copy Tests tab (the last tab in the chart above), those numbers tie in with the next test set... Speed and Copy Tests The 4TB Samsung SSD 870 EVO is ratedat 2,400TBW with a five-year warranty (whichever happens first, the warranty end or the write limit), which is right within standard expectations for SATA-based TLC drives these days at that capacity. TBW scales with capacity, as you can see in the chart above. random write showed similar performance between all tested drives. Here, the 1TB Samsung 870 EVO peaked at 63,269 IOPS with 2,022µs, while the 4TB model showed a peak at 63,542 IOPS at 2,012µs. As an upgrade to the 860 EVO, the 850 EVO, or even any other SATA SSD, it doesn't make a whole lot of sense. I've said it before and I'll say it again, upgrading SATA for SATA doesn't make a lot of sense. At least, not unless you have a drive failure and it needs replacing. There are no serious differences between these SSDs if we look at their benchmark scores. However, the Samsung 870 EVO is winning over the MX500 in terms of random read and write speeds. 3. Endurace

Sequential Read Up to 560 MB/s Sequential Read * Performance may vary based on system hardware & configuration All of these tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. This allows us to repeat the same workloads across a wide range of storage devices, including flash arrays and individual storage devices. Our testing process for these benchmarks fills the entire drive surface with data, then partitions a drive section equal to 5% of the drive capacity to simulate how the drive might respond to application workloads. This is different than full entropy tests which use 100% of the drive and take them into steady state. As a result, these figures will reflect higher-sustained write speeds. Not only is it rated to be endurant, but it's also potentially very secure with the option to use TCG Opal 2.0-compliant AES 256-bit full disk encryption for those whose data needs the added protection from prying eyes. Software and Accessories The PCMark 10 copy tests are also derived from PCMark 10 traces. At first, these numbers might look low compared with the straight sequential-throughput numbers achieved in benchmarks like Crystal DiskMark 6.0 and AS-SSD, charted below. But that's due to the way this score is calculated and the nature of (and differences between) the source data sets. Next, we looked at our VDI benchmarks, which are designed to tax the drives even further. These tests include Boot, Initial Login, and Monday Login. Looking at the Boot test, the 1TB Samsung 870 EVO peaked at 26,502 IOPS at a latency of 1,304ms while the 4TB model peaked at 27,582 IOPS at 1,234ms.

It'll be a sweater-weather kind of day down below before we see SATA 3.0 speeds make any sort of jumps in sequential throughput, so until then, companies like Samsung are focusing their storage efforts where they can: improving speeds for real-world 4K random read and write scenarios. On paper, the 870 EVO seemed like a modest refresh of the last-gen model; however, results from our benchmarks told a slightly different story. For performance, we looked at both the 1TB and 4TB models and compared them to three other consumer-grade 2.5-inch SATA SSDs: the OWC Mercury Extreme Pro, Seagate FireCuda 120, and its predecessor, the 860 EVO. We test all of our SATA and PCI Express 3.0 SSDs on PC Labs' main storage testbed, which is built on an Asus Prime X299 Deluxe motherboard with an Intel Core i9-10980XE Extreme Edition CPU.
