Samsung 850 SSD - RAPID 기능 (속도향상)

(빨간띄가 있는 제품들) 삼성 SSD에서 RAPID기능이 있다. 

해당 기능을 사용하면, 읽기와 쓰기 속도가 증가하게 된다.

RAPID 모드는 DRAM을 Cache로 이용해서 DISK에 읽고 쓰기를 사용하는 방식(?)이라고 함;; 

정말 개발서버에서 RAPID 테스트를 했는데, 정말 놀라울정도의 퍼포먼스를 보여줌(오호 신세계임).

Samsung Magician 툴을 이용해서 RAPID기능 활성화

What is RAPID mode?

RAPID mode is paired exclusively with Samsung 840 EVO SSDs and available as a feature of the accompanying Samsung SSD Magician Software Toolset (version 4.2 and later). When enabled, RAPID mode is inserted as a filter driver in the Windows storage stack. The driver actively monitors all storage-related activity between and among the operating system, user applications and the SSD. The RAPID technology analyzes system traffic and leverages spare system resources (DRAM and CPU) to deliver read acceleration through intelligent caching of hot data and write optimization through tight coordination with the SSD.

ATTO

Astonishing. Previous speeds were 559MB/s Read and 537MB/s Write, and with RAPID Mode enabled we’re seeing a nearly unbelievable difference at 3555MB/s Read and 3723MB/s Write!

Crystal Disk Mark

More of the same here, as results here jump to an absurdly fast 6321MB/s Read and 4239MB/s Write (up from 541 / 522 stock) in the Sequential test.

AS SSD Benchmark

Another massive jump, with Sequential Read and at 3602 MB/s and 2380 MB/s, respectively (up from 520MB/s Read and 500MB/s Write in stock mode. And look at the overall score increase, from 1091 jumping up to 36568. Wow.
