RAPID DRAM caching on the Samsung 840 EVO SSD – The Tech Report

Samsung’s 840 EVO is a breath of fresh air in a sea of largely cookie-cutter SSDs. It’s a true original—the first solid-state drive to combine TLC main storage with a faster SLC write cache. Thanks in part to this TurboWrite cache, the EVO is quick enough to keep pace with high-end SSDs. In some tests, it’s even faster than Samsung’s flagship 840 Pro.
