Samsung 860 EVO 500GB SATA SSD

The Samsung 860 EVO 500GB offers more than double the storage capacity of the SU650. It retains the 2.5-inch SATA III form factor, ensuring compatibility with the same bays. This drive is ideal for users upgrading from HDDs who value encryption and a long warranty. You get 500GB of space compared to the 240GB in the original. It fits desktops and laptops with standard 2.5-inch bays. If you need more room for files and applications, this is the better pick. It sacrifices the specific SLC caching features of the SU650 for larger capacity and robust data protection.

KingSpec 512GB M.2 SATA III SSD

The KingSpec 512GB M.2 SATA III SSD differs by using an M.2 2280 form factor instead of the 2.5-inch size. It provides 512GB of storage, which is more than double the SU650 capacity. This option is suitable for users with compatible M.2 SATA slots who need moderate storage. It does not fit systems requiring NVMe connectivity or Mac users. If you have an M.2 slot and need more space, this is a viable alternative. It gives up the physical compatibility of the 2.5-inch drive for increased capacity and a smaller footprint.

Addlink S20 512GB 2.5-Inch SATA SSD

The Addlink S20 512GB SATA SSD provides 512GB of storage, offering more than double the capacity of the SU650. It uses a 2.5-inch form factor, matching the physical dimensions of the original drive. This drive features SLC caching and 3D NAND technology, similar to the SU650's approach to performance. It is designed for PS4 upgrades and 2.5-inch SATA replacements. You should pick this if you need reliable 512GB storage for consoles or laptops. It delivers solid SATA performance without needing NVMe speeds, making it a practical upgrade for users who want more space.

Silicon Power A55 512GB 2.5-Inch SATA SSD

The Silicon Power A55 512GB 2.5-inch SATA SSD provides double the space of the ADATA SU650. It shares the same 2.5-inch form factor and SATA III interface. This drive includes ECC protection for data integrity, similar to the reliability features in the SU650. It is the right pick for users upgrading from small 240GB drives who need more room. You get 512GB of storage without switching to M.2 slots. If you require more capacity while maintaining compatibility with standard bays, this is a strong alternative. It offers reliable performance for everyday computing tasks.
