Silicon Power Ace A55 512 GB
Capacity-specific catalog record for manufacturer model/SKU SP512GBSS3A55S25. Specifications are scoped to this capacity and the cited model information; other capacities and revisions may differ.
IDENTIFICATION: Match the full SKU SP512GBSS3A55S25, capacity, and label/revision before service or replacement. This is a consumer 2.5-inch SATA drive, not an enterprise model or an NVMe device.
Specifications & compatibility
| Manufacturer / model / SKU | Silicon Power Ace A55 // SP512GBSS3A55S25 |
|---|---|
| Capacity | 512 GB nominal model capacity. |
| Form factor / interface | 2.5-inch, 7 mm height; SATA III 6 Gb/s. |
| NAND | 3D NAND; the manufacturer does not lock a single NAND supplier/cell revision for all production batches. |
| Rated sequential performance | Up to 560 MB/s sequential read and 530 MB/s sequential write (manufacturer family maximum). These are published peak figures, not a guarantee of sustained writes or every host workload. |
| Endurance | 250 TBW in the independent model database; treat batch-specific internals and service limits as revision-dependent. TBW is a rated-write limit, not a prediction of an individual drive's service life. |
| Host compatibility | Requires a 2.5-inch SATA bay, standard SATA data and power connections, and a host that supports SATA storage. SATA III negotiates with earlier SATA generations at their supported rates; check the 7 mm caddy clearance and OS/driver TRIM support. |
| TRIM / SMART / firmware | Use the host OS, SATA controller, and firmware tools supported for this exact model/revision. TRIM and SMART pass-through depend on the OS driver, controller mode, enclosure, and bridge; check vendor documentation before firmware changes. |
Preservation & maintenance
- Record the label, exact SKU, serial, firmware, host/controller, and a read-only SMART snapshot before migrating or changing settings.
- Keep independent, verified backups. A TBW rating, SMART indicator, warranty, or wear estimate is not a guarantee of data retention or remaining life.
- Use the manufacturer's exact-model guidance for firmware, secure erase, encryption, diagnostics, and warranty; preserve the original label and firmware state.
- Do not assume identical NAND or controller internals across production batches unless the manufacturer identifies the revision.
