Manufacturer description

The Silicon Power A58 1TB internal SSD is a straightforward SATA III upgrade for any laptop or desktop still running a mechanical hard drive. Built on 3D NAND TLC flash, the A58 delivers better power efficiency and higher endurance than older 2D NAND drives, which translates to longer runtime on battery and a drive that holds up through years of daily writes. Silicon Power pairs the NAND with SLC cache technology, so bursts of file copying and application launches land in fast cache memory before settling into main storage. The 7mm, 2.5-inch form factor is the reason this drive shows up in…

Frequently Asked Questions

Will this SSD fit my laptop?

It uses the standard 2.5-inch form factor at 7mm (0.28 inches) thick, designed for ultrabooks and ultra-thin notebooks. Check that your laptop has a 2.5-inch SATA bay rather than M.2-only storage.

Is this an NVMe drive or SATA?

This is a SATA III 2.5-inch drive, not NVMe. It connects to a standard SATA port, so it works in older laptops and desktops that have no M.2 slot.

What warranty does Silicon Power offer on the A58?

The A58 carries a 3-year limited warranty. Silicon Power asks that you register the product on the official SP website to receive full manufacturer warranty service and product support.

How reliable is this drive?

On the hardware side it uses 3D NAND flash plus ECC error checking, TRIM, and garbage collection, which Silicon Power lists as its reliability features.

Does it come with cloning software or a mounting bracket?

The listing does not specify included accessories or software. Check the current product listing before buying if you need a 2.5-to-3.5-inch desktop bracket or migration software.
