For the Acer Aspire 5 A515-45, the best-supported starting point for a primary-drive upgrade is an M.2 2280 NVMe SSD. But A515-45 is a model family, not a complete configuration identifier: check the laptop’s full SKU and region before ordering, especially if you want to add a second 2.5-inch SATA drive.
What SSD should you look for?
For the primary drive, start by filtering for M.2 2280 form factor and NVMe/PCIe interface. Acer specifies those details, including PCIe 3.0 x4, for its A515-45-R478 configuration in its Brazil product listing.

That specification is a useful match for the R478, not proof that every A515-45 variant has the same storage arrangement or limits. Acer’s US listing for the A515-45-R74Z identifies a 256 GB PCIe SSD but does not state the M.2 length on that page.

Find the complete SKU on the laptop’s label, packaging, invoice, or system information screen, and match it to the Acer support or product page for your country. Acer’s Aspire 5 manual covers A515-45, A515-45G, A515-45S, and A515-46. That shared manual coverage does not establish that all of those variants have identical storage bays, hardware, or capacity limits.

Before checkout, verify the drive’s length and interface against the exact configuration. The available specifications establish PCIe 3.0 x4 for the R478, but they do not establish a maximum NVMe generation or maximum primary-drive capacity for every A515-45.
Can you add a second 2.5-inch SATA SSD?
Some configurations may support a second drive, but verify the bay and installation hardware for your individual laptop. Acer’s Brazil listing for the A515-45-R478 describes an occupied M.2 slot and a free SATA 3 bay for a 2.5-inch drive. It lists up to 2 TB for that secondary drive; treat that capacity and bay description as applying to the regional R478 listing, not as a family-wide guarantee.

An Acer Community accepted answer about the A515-45-R74Z also describes one M.2 PCIe 3×4 slot and one 2.5-inch SATA-3 space. This is community guidance for the discussed unit, rather than an Acer product specification. Neither source confirms that your particular laptop includes the SATA cable or mounting bracket.
- Choose a 2.5-inch SATA SSD only after confirming that your exact SKU has the bay.
- Check whether the SATA cable and mounting hardware are present or need to be obtained separately.
- Do not confuse a 2.5-inch SATA drive with an M.2 NVMe drive; they use different form factors and interfaces.
How to compare compatible drives
Once compatibility is established, compare drives on the factors that matter for your budget and use. A higher advertised speed or larger capacity does not make an incompatible drive suitable.

- Price: Compare the cost of drives with the same form factor and interface.
- Endurance and warranty: Check the manufacturer’s stated endurance rating and warranty terms for the specific model.
- Performance: Match expectations to the laptop’s interface. Acer specifies PCIe 3.0 x4 for the R478; that does not establish the interface limit of every A515-45 configuration.
- Installation needs: For a second 2.5-inch drive, include any required cable or mounting hardware in your plan.
Quick buying checklist
- Identify the full model SKU, such as A515-45-R478 or A515-45-R74Z, and confirm the country or regional configuration.
- For a primary-drive replacement or upgrade, use M.2 2280 NVMe as the starting filter, then confirm the exact laptop specification.
- For a second drive, confirm the 2.5-inch SATA bay and required cable and bracket for your unit.
- Compare capacity, price, endurance, warranty, and performance only among drives that match the verified interface and form factor.
