Detailed comparison

Performance

The SSD-PG500U3B is better aligned with file-transfer and mobile-workflow needs because it is an SSD and has a stated read speed of up to 340 MB/s. Review feedback also praises its speed for large files, although some reviews concern other listed capacities or styles and should not be treated as a guarantee for this 500 GB model. The adu3 HDD performs well for TV recording and general storage, but one review found its transfers slower than rival products. For simple stationary storage, Product A is sufficient; for portable performance-oriented workflows, Product B is the more suitable design.

Speed

Product B has a slightly higher speed score and lists read speeds up to 340 MB/s, so it is the clearer choice for buyers who expect to move large files regularly. Product A's review feedback includes both “relatively fast” use and a comment that it may be slower than other brands, making its speed picture less consistent. Actual results will still depend on the host device, USB connection and file types.

Reliability

Product A has the stronger reliability score. Its available reviews focus on successful operation, quiet use and straightforward TV setup, though they do not establish long-term durability. Product B has positive reports of dependable use, but the supplied reviews also include isolated complaints of data corruption, performance loss and support difficulties. These reports do not prove every SSD will have problems, but they make Product A the more conservative choice on the provided reliability data.

Final verdict

The Buffalo adu3 Series HDD is the best overall option in this comparison because it achieves the higher overall score and is more convincing for easy, quiet, value-focused external storage. It is the practical recommendation for TV recording and buyers who want uncomplicated setup, while accepting an external power adaptor and potentially slower transfers.

The BUFFALO SSD-PG500U3B is the better specialised choice for portable storage. Its USB-C and USB-A support, compact form factor, stated device compatibility and registered three-year warranty are meaningful advantages for travel, multi-device workflows and compatible console use. However, its lower overall score, mixed durability and reliability feedback, and potentially more involved PS5 setup mean it is best chosen for its specific strengths rather than as the default option for every buyer.

Frequently asked questions

Which is better overall: the Buffalo adu3 Series HDD or the BUFFALO SSD-PG500U3B?

The Buffalo adu3 Series HDD is the higher-scoring overall product in the supplied comparison data. It leads on usability, value, reliability and customer satisfaction. The SSD-PG500U3B remains the more suitable choice when compact carry, USB-C connectivity, broad stated device support and its registered three-year warranty matter more than the HDD's stronger overall score.

Is the BUFFALO SSD-PG500U3B faster than the Buffalo adu3 Series HDD?

The SSD is the more appropriate choice for buyers focused on portable solid-state storage, and its listing specifies read speeds up to 340 MB/s. However, the supplied speed scores are close, and the available SSD feedback also includes occasional complaints about reduced speed. For the HDD, one review specifically described transfers as slower than competing products.

Which drive is easier to set up?

The Buffalo adu3 Series HDD has the stronger setup score and reviews describe simple connection and configuration for TV recording. The SSD is also generally presented as easy to use, especially on PCs, but one detailed PS5 review described a more involved formatting process that may require Buffalo's DiskFormatter2 utility.

Which product is better for PS4 or PS5 storage?

The SSD-PG500U3B is explicitly listed as compatible with PS4 and PS5, and its reviews discuss console use. Buyers should still check their console's external-storage rules before buying. One review notes that external storage on PS5 was used for storing and playing PS4 games, while PS5 game use has different requirements.

Which is more portable?

The SSD-PG500U3B is clearly the more portable option. Its compact form factor is intended for carrying data on the go, and it has the higher portability score. The adu3 HDD is described as compact enough for placement behind a TV, but a review notes its larger size and need for a power adaptor.

Which drive offers better value?

The adu3 Series HDD has the stronger value score and is praised in the available reviews for reasonable pricing. That does not automatically make it the right purchase for every buyer: the SSD adds USB-C support, high portability, listed console compatibility and a clearer warranty arrangement. Value depends on whether those SSD-specific benefits are needed.

Are there durability or reliability concerns with either drive?

Both products warrant some caution. For the HDD, the supplied interpretation says long-term durability is uncertain, and one reviewer had not yet assessed it. The SSD has mixed durability feedback: some buyers praise its sturdy design, while other available feedback mentions a thin plastic shell, data corruption or slowed performance.

Does the SSD-PG500U3B include a warranty?

Yes. The listing states that the SSD-PG500U3B has a three-year warranty for registered devices and a two-year warranty when unregistered. No comparable warranty terms were provided for the Buffalo adu3 Series HDD, and its warranty-support score is lower in the supplied scoring data.
