Description
Featuring the sturdy and quality iron case, the advanced SATA interface and a powerful controller, this solid state drive is the ideal high-speed, lightweight and shockproof solution. Boasting a compact form factor and super slim thickness, this SSD provides superior performance and reliability to notebooks, desktops, servers and workstations.
- Advanced Global Wear Leveling and flash bad-block management for reliability
- Supports Advanced Garbage Collection
- Features a DDR3 DRAM cache
- Built-in Error Correction Code (ECC)
- Advanced Power Shield to prevent data loss in the event of a sudden power outage
- Supports DEVSLP SATA low power mode
- RoHS compliant
- Provides great shock resistance
- Slim, elegant and lightweight design
- Wear Leveling algorithm
The controller supports static / dynamic wear leveling. When the host writes data, the controller will find and use the block with a low erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks erase count is higher than the data blocks, it will activate the static wear leveling, replacing the not-so-frequently-used user blocks with the high erase count free blocks. - Bad-block management
When the flash encounters ECC fail, program fail or erase fail, the controller will mark the block as a bad block to prevent using this block and cause data loss in the future. - StaticDataRefresh technology
To prevent the accumulation of error bits in the read transaction, the controller monitors the error bit levels at each read operation; when it reaches the preset threshold value, the controller automatically performs data refresh to restore the correct charge levels in the cell. This implementation practically restores the data to its original, error-free state, and hence, lengthening the life of the data.
