Capacity and form factor

The ADATA Ultimate SU630 is a 2.5 inch internal solid-state drive with a 480GB capacity. It uses 3D QLC NAND flash and a SATA interface for desktop or laptop upgrades. The drive targets consumers who want an affordable replacement for a mechanical hard disk. It includes a 1.5 million hour MTBF rating for long-term reliability.

SATA interface limits

The SATA III connection caps maximum sequential read at 520 MBps and sequential write at 450 MBps. Random performance reaches 40,000 IOPS for 4KB reads and 65,000 IOPS for 4KB writes. Hardware LDPC error correction and SLC caching help maintain data integrity and sustain speeds under load. The drive operates between 0 and 70 degrees Celsius.

Compatibility checks

Verify that your system has a free 2.5 inch drive bay and a SATA data plus power connector. Confirm the operating system supports the SATA III standard for full throughput. The supplied SSD Toolbox and Migration Utility simplify cloning and ongoing health monitoring. No additional hardware is required beyond standard SATA cabling.

Questions about this item

Should I pick the 480 GB SU630 or the larger 960 GB version?

Choose 480 GB if you only need space for the operating system and a handful of applications; the 960 GB model simply doubles the available capacity while keeping the same 520 MB/s read and 450 MB/s write limits.

Will I actually see 520 MB/s read speed in my laptop?

In a typical SATA III system the drive will deliver close to 520 MB/s for large sequential reads, while everyday mixed workloads run at the 40,000 IOPS random-read and 65,000 IOPS random-write rates.

Does the SATA III interface cap the SU630 below its rated speeds?

SATA III tops out at 6 Gb/s, so the published 520 MB/s read and 450 MB/s write are already the practical ceiling; the drive cannot exceed them regardless of the controller.
