Samsung has dominated the SSD market for a very long time, and every new consumer SSD model the company introduces is noteworthy. The latest product to reach the shelves is the new range of 870 EVO SSDs, building on a decade-long legacy of SATA SSDs. We have tested the 1 TB and 4 TB models from this new product family. Pushing for SATA

In sequential Crystal DiskMark speeds, the SSD 870 EVO hits Samsung's own rated spec without a sweat, while 4K results were just a bit stronger, but still a bit slower than expected when comparing the 4TB and 1TB variants of the same drive. 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 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.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. 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.

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.

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. that is, or may reasonably be considered to be, defamatory, libelous, hateful, racially or religiously biased or offensive, unlawfully threatening or unlawfully harassing to any person or entity; 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
