Specification & Features

V-NAND Technology



- More capacity
- More speed
- More endurance
- More power efficiency
Samsung's new 3D V-NAND will be used for a wide range of consumer electronics and enterprise applications, including solid state drives (SSDs). Consumers can expect their handheld computers to perform better for longer periods of time between charges. Datacenter managers can expect increased productivity and longevity while saving on their power bill.

SAMSUNG Magician Software

With Magician 4.0, Samsung is introducing a host of improvements designed to enhance user experience and to make Magician’s features more user-friendly and accessible to novices. The totally redesigned User Interface (UI) features simple, graphical indictors to show SSD health status and Total Bytes Written (TBW) at a glance. Users can now determine SATA and AHCI compatibility and status without consulting their user’s manuals. The updated Benchmarking feature lets users test other storage devices so that they can clearly see the dramatic performance improvements their new Samsung SSD delivers.
Particularly dramatic improvements have been made to the OS Optimization feature with a simpler, tabbed interface providing access to 3 optimization profiles (Maximum Performance, Maximum Capacity, & Maximum Reliability), along with detailed descriptions of each OS setting and why they are turned on or off for each profile. This feature should reduce user confusion about OS configuration, a common question among new SSD users, and the Magician team is excited to outline what’s changed.

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.
