Samsung 870 EVO Internal SSD (MZ-77E2T0B/AM) 2TB 2.5" SATA III

Product Information

Each capacity should measure similar to that of the 860 EVO - typically, it will have a 6GB-12GB of static SLC cache paired with a dynamic SLC cache that spans tens of gigabytes. Speed degradation was not apparent in our testing of the 1TB and 4TB model, but it may impact the smaller models. The drive also loses slightly to the Samsung 870 QVO in our AS-SSD copy tests, though not by enough to be perceptible to most users in real-world use. 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. But for new system builders, this is an SSD to put on the shopping list. I've been using Samsung SSDs for many years and have never once been let down or disappointed in any way. And the 2TB model I have here is good value, too. When the 860 EVO launched you were paying the same for 1TB as you now are for 2TB with the 870 EVO. In each of these tests, the Samsung SSD 870 EVO proved itself not only as a leader among SATA drives, but also a regular competitor with both PCIe 3.0 and PCIe 4.0-based NVMe M.2 drives. While both of those standards are great for what they do (hitting all-time sequential throughput records), their added bandwidth doesn't always translate to better 4K random read and write scores, which is what a large percentage of SSD buyers in this category tend to care about most.

Random Read (4KB, QD1) Up to 13,000 IOPS Random Read * Performance may vary based on system hardware & configuration ** Measured with Intelligent TurboWrite technology being activated Given the roughly three-year cadence Samsung has set for their SATA SSD updates, the 870 generation may also be the last. Samsung 870 EVO Specifications 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.

Truth be told, there aren't that many new SATA SSDs on the market. To put this into perspective, the most recent SATA competitor we reviewed, the SK hynix's Gold S31, was launched in 2019. Finally, in our VDI Monday Login, the 1TB Samsung 870 EVO had a peak performance of 12,161 with a latency of 1,323ms while the 4TB model showed a peak of 14,323 IOPS with a latency of 1,113ms. Let’s see what are the key offerings given by the manufacturers of these SSDs. Comparing them will give you a good idea of what you can expect from them. Specification Samsung is one of the few companies still putting significant effort into SATA SSDs and releasing new consumer SATA models. As PC OEMs have overwhelmingly switched to using NVMe SSDs in new systems, even on the smaller capacities, the client/consumer SATA SSD market now exists almost entirely for the sake of DIY system builders and aftermarket upgrades on older systems. Most major consumer SSD brands have either stopped updating their SATA models, or decided to quietly update components without the fanfare of a new model release. Then there are companies creating odd-ball models, such as a 15.36 TB design. Either way, we don't get many new consumer SATA SSDs in for review these days. The Samsung 870 EVO is the latest entry into the company’s successful line of consumer SSDs. The EVO line has been a highly successful endeavor for the company, as the line finds the perfect balance between performance and price while offering Samsung’s pedigree in reliability. These mid-range consumer drives are designed for all kinds of use cases, from everyday use and gaming, to those looking for a decent upgrade in performance for PC and even just those looking for a reliable SATA SSD.

The other factor in this is that we recently updated our SSD test suite for 2021, which means re-testing older drives for new performance numbers. In our SSD test suite 2021 article, we prioritized NVMe SSDs, as that is where the market is. We are getting around to retesting the older SATA drives, although these take the longest time to complete - 24 hours for a fast 1 TB drive, up to 100 hours or more for a 4 TB drive,not including the analysis. Performance-wise, the Samsung 870 EVO is quoted to deliver sequential read and write speeds of 560MB/s and 530MB/s, respectively, while random performance is expected to hit up to 98,000 IOPS read and 88,000 IOPS writes. This is only a slight upgrade in sequential read performance over the 550MB/s offered by the 860 EVO (which is expected, since the drive’s performance is capped by the SATA interface), with Samsung claiming a 38% increase in random read performance speeds. To help sustain these performance numbers, the EVO line leverages Intelligent TurboWrite technology. With these numbers, we can clearly see that the Samsung 870 Evo has some better things to offer. Total endurance, sequential write speed, and random read speed are better in the Samsung 870 Evo. Whereas the Crucial MX500 is winning the other things such as M.2 Form Factor, and random write speed. 2. Benchmark Scores 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 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. Switching over to sequential performance, the 1TB Samsung 870 EVO drive peaked at 7,705 IOPS or 480MB/s with a latency of 2,070µs in reads while the 4TB model hit 486MB/s and 2,043µs in reads for top spot. We generally disapprove when SSD vendors silently swap out major components without renaming a product, because changing the SSD controller or NAND flash can have a major impact on a drive's performance and power efficiency. Unfortunately, this has long been a common practice for entry-level models, and a few manufacturers have tried it on more upmarket models and been deservedly excoriated when they're caught (eg. ADATA, with the SX8200 Pro).
