Random Read (4 KB, QD32) Up to 98,000 IOPS Random Read * Performance may vary based on system hardware & configuration ** Measured with Intelligent TurboWrite technology being activated It is worth noting that the enterprise SATA SSD market has seen somewhat more in the way of visible activity, because the longer product lifetimes in that market and the higher profit margins give SATA SSDs more of a long tail of commercial relevance.) When it comes to benchmarking storage devices, application testing is best, and synthetic testing comes in second place. While not a perfect representation of actual workloads, synthetic tests do help to baseline storage devices with a repeatability factor that makes it easy to do apples-to-apples comparison between competing solutions. These workloads offer a range of different testing profiles ranging from “four corners” tests, common database transfer size tests, to trace captures from different VDI environments.
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.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. 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. 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. 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.
In terms of NAND, DRAM, and Controller configurations, the Samsung 870 Evo is way better than the Crucial MX500. This might be the reason why 870 Evo was performing better in random read/write tests. 5. Price 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.
On durability, the TBW (or "terabytes written") rating is an estimate of the total amount of allowable lifetime write activity, after which the drive will start to take memory cells out of service as they "wear out." 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. From both aesthetic and functional standpoints, Samsung Magician stands well above the rest. The software features an elegant design that helps to demystify some of the more complex storage-management tasks, such as using Secure Erase or defragmenting the drive.
I feel like this part of the review should be copied and pasted by now when looking at Samsung SSDs. Because, as always, the answer is yes. And unlike the 870 QVO which launched last year, it doesn't just make the most sense when buying the highest capacity, more expensive versions. Then again, the 870 QVO is also targeted at a different type of user. 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 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. 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. 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).

VDI Initial Login, the 1TB Samsung 870 EVO had a peak performance of 14,193 IOPS at a latency of 2,108ms while the 4TB model hit a peak of 17,021 IOPS at 1,755ms before taking a pretty big dip in performance at the very end (though easily taking first place among the tested drives). It has been quite some time, but Samsung has finally released the next iteration of the company’s highly popular 2.5-inch SATA SSD line, the Samsung 870 EVO. This drive leverages Samsung’s 3D V-NAND, features the company’s newest MKX controller, and is available in the same capacity points as the last-gen model (250GB to 4TB). Samsung states that the new 870 EVO boasts sequential read and write speeds up to 560MB/s and 530MB/s, respectively, while random performance is expected to hit up to 98,000 IOPS read and 88,000 IOPS writes, though it didn’t quite reach those levels in our tests.
