Product information

Description

Silicon Power A55 4 TB is a 2.5-inch SATA III SSD designed for PCs and laptops that delivers fast boot times and responsive application loading. Using a SATA III 6 Gb/s interface and 3D NAND flash memory, this SSD provides up to 500 MB/s read and 450 MB/s write speeds and offers 4 TB of storage capacity for files, programs and games.

Advantages

The Ace A55 combines an original controller with 3D NAND to provide stable, durable operation and improved performance, enabling quick system boots and reduced application load times. Built without moving parts, the drive is lightweight, thin, and resistant to shock and vibration. It supports S.M.A.R.T. monitoring and ECC error correction for safer data transmission and includes bad block management to detect and isolate faulty blocks to reduce the risk of data loss. Internal auto-copy technology moves data from the SLC cache to the 3D NAND without burdening the controller or DRAM.

Suitable for

  • Upgrading a laptop or desktop from an HDD to an SSD
  • Users who need large local storage for files, applications and games (4 TB)
  • Everyday tasks such as web browsing, media playback and office work

Key specifications

  • Form factor: 2.5-inch SATA III
  • Capacity: 4000 GB (4 TB)
  • Interface speed: SATA III 6 Gb/s
  • Sequential read speed: up to 500 MB/s
  • Sequential write speed: up to 450 MB/s
  • Flash type: 3D NAND
  • Weight: 0.063 kg

How to use

Install the 2.5-inch SSD into a compatible laptop drive bay or a desktop 2.5" mounting bracket and connect it to a SATA III port and power connector. Initialize and format the drive in your operating system if necessary, then install the OS or transfer data from your previous drive using cloning software. For best performance, connect to a SATA III 6 Gb/s port and ensure your system firmware supports the drive.

Usage recommendations

Use the Ace A55 as a primary system drive for faster boot and application load times; enable S.M.A.R.T. monitoring in your OS and keep regular backups to protect important data.
