Apacer optimizes the continuous random write performance of 3D NAND SSDs through Over-provisioning. With this technology, 7% or more of drive space is reserved. When a later bad block (LBB) is discovered, it will be replaced with a Free Block from the reserved space to stabilize operation and extend product durability.
Users who require longer-lasting SSDs are recommended to choose Over-provisioning. Over-provisioning technology can effectively reduce write amplification and extend the life of an SSD. In 4K random performance and background processing performance, the number of reads and writes per second (IOPS) can be increased by 85% and 65%, respectively.
