Detailed comparison

Performance

Both drives list the same peak SATA performance: up to 520MB/s reads and 450MB/s writes. Each is therefore positioned to improve booting, downloads, and file transfers compared with a mechanical HDD. The SU630 receives the higher performance score and has reviews describing fast operation, including use with virtual machines. The SU650’s reviews also praise speed and faster booting, but one reviewer describes it as reasonable rather than the fastest. For the supplied performance assessment, the SU630 has the edge; for capacity-led everyday use, the SU650 remains competitive.

Speed

On advertised figures, this is a tie: both SSDs specify up to 520MB/s reads and 450MB/s writes. Both also receive review praise for faster booting than a spinning drive. The SU630 has the higher speed score and reports include fast operation in an older PC and comparisons to a Samsung SSD. The SU650 has positive boot-time reports too, but its scoring places it slightly behind. Neither should be chosen expecting speeds beyond a SATA SSD’s class.

Reliability

The SU650 has the higher reliability score and its aggregated review overview says customers find it reliable, with installation and startup generally proceeding without issues. Still, one review reports overheating and eventual failure. The SU630 has many reports of trouble-free use and one reviewer says it was still working fine, but its reliability assessment is lower and a long-term review reports failure after several years. Neither isolated complaint proves a general outcome, but both support the need for current backups.

ADATA Ultimate SU630 480GB Solid State Drive

Pros

  • Up to 520MB/s read and 450MB/s write speeds are specified.
  • Strong upgrade path for replacing a mechanical HDD in a compatible PC or notebook.
  • Dynamic SLC caching and LDPC ECC are included.
  • Includes SSD Toolbox and migration utility support.
  • Light 47g 2.5-inch form factor is easy to handle during installation.
  • Review feedback repeatedly reports faster booting and straightforward upgrades.

Cons

  • 480GB capacity leaves less room for large game libraries, media collections, or multiple virtual machines.
  • QLC NAND is positioned as a value-focused storage option.
  • Long-term reliability evidence is mixed; one review reports failure after several years.
  • Its SATA interface limits it to SATA-class performance rather than newer storage standards.
  • Warranty and support information is limited in the supplied data.

ADATA Ultimate SU650 1TB Internal SSD

Pros

  • 1TB capacity provides substantially more storage than the 480GB alternative.
  • Up to 520MB/s read and 450MB/s write performance is specified.
  • LDPC error correction supports data integrity.
  • Reviews frequently praise easy installation, fast booting, and good value.
  • At 30g, it is lighter than the SU630.
  • Includes downloadable ADATA file-management and data-migration software.

Cons

  • It remains a SATA SSD, so its specified speeds are modest beside newer storage options.
  • One review reports overheating and eventual failure during problematic Windows updates.
  • A reviewer notes the plastic casing and a lack of bottom screw threads, which could complicate some installations.
  • Long-term endurance should not be assumed from short-term installation feedback.
  • Warranty and support information is limited in the supplied data.

Final verdict

The ADATA Ultimate SU650 1TB is the best overall choice in this comparison. It combines substantially greater capacity with the same advertised up-to-520MB/s read and 450MB/s write ratings as the SU630, while earning slightly stronger overall, setup, usability, reliability, value, and customer-satisfaction assessments. It is the more flexible option for buyers whose storage needs may grow beyond a basic boot drive.

The ADATA Ultimate SU630 480GB remains a valid alternative rather than a poor second choice. It has higher performance and speed scores, supports the familiar 2.5-inch SATA upgrade path, and has positive review feedback from users replacing older hard drives. Pick it when 480GB is enough and the listing’s PC/notebook positioning fits the device. For either model, SATA compatibility, mounting requirements, current price, and a dependable backup routine should determine the final purchase.

Frequently asked questions

Which is better overall: the ADATA SU630 480GB or SU650 1TB?

The ADATA SU650 1TB is the narrow overall winner because it has a slightly higher overall score, stronger usability, reliability, value, and customer-satisfaction results, plus more than twice the capacity. The SU630 remains a sensible choice when 480GB is sufficient and its stronger performance and speed scores matter more.

Do the ADATA SU630 and SU650 have different advertised speeds?

Not in their supplied peak specifications. Both drives are rated for up to 520MB/s reads and 450MB/s writes over SATA. The SU630 receives higher performance and speed scores in the comparison data, but buyers should not expect either SATA model to offer performance beyond the limits of its interface.

Which ADATA SSD is better for an HDD upgrade?

Both drives are suited to replacing a mechanical hard drive and have reviews describing noticeably faster booting and easier everyday use. Choose the SU630 for a compatible PC or notebook when 480GB is enough. Choose the SU650 when a compatible desktop needs the extra room of a 1TB drive.

Is the ADATA SU650 1TB better for games and larger files?

The SU650 is the more practical option for larger game libraries and general file storage because it offers 1TB rather than 480GB. Its reviews include use as a game drive and praise its capacity. It shares the SU630’s advertised SATA read and write limits, so capacity is the clearer advantage.

Which drive is easier to install?

The SU650 has the higher setup and usability scores, and reviews repeatedly say it installed, formatted, and was recognized easily. The SU630 also has strong setup feedback, including reports of easy migration and installation. Installation still depends on having a compatible 2.5-inch SATA bay, connector, and mounting arrangement.

Which SSD has better reliability feedback?

The SU650 has the higher reliability score and its aggregated review overview describes reliable installation and operation. However, one review reports overheating and failure. The SU630 also has many positive reports of continued operation, but one long-term review reports a failure after several years. Backups remain important with either drive.

Do both drives include migration software?

Yes. The SU630 listing mentions SSD Toolbox and a migration utility for drive status, wear-level, lifespan, and migration tasks. The SU650 listing mentions downloadable ADATA SSD file-management and data-migration software. Reviewers for both product families also describe cloning or restoring systems during their upgrades.

Which is better value, the SU630 480GB or SU650 1TB?

The SU650 has a marginally higher value score and combines 1TB capacity with the same advertised peak read and write speeds as the SU630. The SU630 also scores strongly for value and can be the more appropriate purchase when a 480GB drive meets the intended storage requirement. Check current pricing before deciding.
