Optimal SATA III Performance

Speeds are more consistent, even with heavy workloads and multi-tasks.* The 860 EVO performs at sequential writes up to 520 MB/s** with Intelligent TurboWrite technology, and sequential reads up to 550 MB/s. The TurboWrite buffer size*** varies from 12 GB to 78 GB for faster file transfer. Sequential reads up to 550 MB/s Sequential writes up to 520 MB/s. The TurboWrite buffer size* is upgraded from 12 GB to 78 GB.

* As compared to Samsung 850 EVO.

** Performance may vary based on SSD's firmware version and system hardware & configuration. Sequential write performance measurements are based on Intelligent TurboWrite technology. Sequential performance measurements based on CrystalDiskMark v.5.0.2 and IOmeter 1.1.0. The sequential write performances after Intelligent TurboWrite region are 300 MB/s for 250 / 500 GB and 500 MB/s for 1 TB. Test system configuration: Intel Core i5-3550 CPU @ 3.3 GHz, DDR3 1333 MHz 4 GB, OS – Windows 7 Ultimate x64, Chipset: ASUS P8H77-V

*** The TurboWrite buffer size varies based on the capacity of the SSD‡ 12 GB for 250 GB model, 22 GB for 500 GB model, 42 GB for 1 TB model and 78 GB for 2 / 4 TB. For more information on the TurboWrite, please visit
