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. 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 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. 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.

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. As we all know these both SSDs use the SATA protocol, and the speed would never go beyond 600MB/s. So, whether you are using any of these SSDs, don’t expect anything more than that. However, because the Crucial MX500 and Samsung 870 Evo are competing hard in this domain, various people want to know which one is the best between these both. So, in this article, we are going to reveal the same by doing some straight comparisons. Now, without any further delays, let’s get started. 1. Theoretical Specifications

Both these SSDs are great in terms of reliability as well. They offer a good warranty period along with the TBW limits. Let’s compare them below. Specifications 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. Sequential Read Up to 560 MB/s Sequential Read * Performance may vary based on system hardware & configuration In that quest, the Samsung SSD 870 EVO succeeds handily, setting new records for SATA while also keeping the drive just about competitive with M.2 drives when launching games or Adobe Photoshop. If you're married to SATA pricing (or your PC can't handle anything else) but want to optimize 4K performance, the Samsung SSD 870 EVO is the best new SATA drive of the early days of 2021. It should be at the top of anyone's list who wants the best combination of performance, product quality, and price in a 2.5-incher.

Looking inside the cases, it’s interesting to see how small the drives have become. While the 2.5″ SATA case is a bit overkill for these drive innards, the compact nature of these next-generation drives is more towards how they get leveraged in small external devices. Not a lot is needed to hit the capacity requirements. Samsung 870 EVO PerformanceIn 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

that violates any law, statute, ordinance or regulation (including, but not limited to, those governing export control, consumer protection, unfair competition, anti-discrimination or false advertising);

Samsung's first new SSD of the year is, as you might expect, very good.

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. 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 First up is random 4K read, where the 1TB Samsung 870 EVO 74,587 IOPS at 1,715µs in latency, while the 4TB model had slightly better results with a peak of 75,310 IOPS at 1,695µs in latency. Their predecessor, the Samsung 860 EVO, wasn’t far behind. 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. 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).

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. 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.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.
