The ADATA SU630 SSD is built with next-generation QLC 3D NAND Flash to offer amazing value and great performance. It also comes with excellent features such as LDPC ECC technology. 3D QLC SSD - high capacity without breaking the bank Sporting the QLC 3D NAND Flash, the SU630 is an ideal upgrade for users looking to make the switch from HDD to SSD, whether as storage or a boot drive. Performance boost with dynamic SLC caching Featuring dynamic SLC caching, NAND Flash memory operates in single-level cell mode and boosts performance. This allows the SU630 to reach read/write speeds of up to 520/450 Mbps for smoother and faster boot, file transfers, and downloads. Improved data integrity With support for LDPC (Low-Density Parity-Check) error correcting code technology, the SU630 can detect and fix errors to ensure data integrity and thus enjoy an extended lifespan. Tougher, quieter, more reliable With no mechanical components, SSDs are more resilient than HDDs. They are more resistant to shock, vibration (1500G/0.5ms) and extreme temperatures (0-70 °C) and therefore provide better protection for data. What's more, SSDs also run silently and consume less power.
