Addlink S20 1TB SATA III Internal SSD - PS4 Compatible Upgrade

In this review the Addlink S20 1TB SATA III internal SSD is evaluated as a straightforward capacity and speed upgrade for consoles and PCs. It is ideal for users who want a simple, affordable replacement for a laptop or desktop hard drive or to expand game storage in a PS4, offering up to 500/450 MB/s read/write in ideal conditions. The drive's real appeal is practical: a drop-in SATA III 2.5' form factor with a 7mm height that makes installation easy and delivers a noticeable boost in boot, load and general responsiveness.

Key Features

• PS4 Compatible: Works as a direct replacement in Sony PS4 systems to increase game storage and reduce load times compared with mechanical drives.
• High Sequential Speed: Advertised up to 500 MB/s read and 450 MB/s write speeds that provide quicker boot and file transfer times on compatible SATA III hosts.
• SATA III Interface: Uses SATA III 6 Gb/s with backward compatibility to SATA I and SATA II so it will function in older laptops and desktops.
• Slim 7mm Profile: The 7mm, 2.5' thickness ensures the drive fits in most laptops and consoles without an adapter, simplifying upgrades.
• Three-Year Limited Warranty: Covered by a 3-year limited warranty tied to TBW endurance, giving standard manufacturer support for everyday use.

Who It's For

The Addlink S20 1TB SSD is best for PS4 owners who want to move away from a slow hard drive to faster game loading and for laptop or desktop users seeking an affordable capacity upgrade that noticeably improves system responsiveness. It is a practical choice for users on a budget who need a full terabyte for games, media or work files.

Users who need the absolute highest sustained write performance for heavy professional workloads, or who prefer drives with long enterprise endurance ratings, should consider higher-end NVMe or enterprise SATA models instead. Also note actual speeds vary by host, interface and workload, so real-world performance can be lower than the listed maximums.

Pros & Cons

Pros

• Good sequential read/write figures advertised, delivering faster boot and load times versus HDDs.
• Compatible with PS4 and a wide range of laptops and desktops thanks to SATA III and 7mm form factor.
• Generally positive feedback on installation ease and value for money from users who migrated Windows 10 systems or consoles.

Cons

• Durability feedback is mixed; some customers reported failures shortly after setup, so endurance may not match premium-tier drives.
