Silicon Power 1TB SSD


Time is Money! Don’t Waste It

Still wasting precious time while booting your computer or loading applications? Then it’s time to get rid of your old hard drive and switch to an SSD. Powered by SATA III 6GB/s interface, the A55 is able to boot your computer or launch applications within seconds.

Ace A55 An Upgrade as Easy as 1-2-3

An Upgrade as Easy as 1-2-3

Upgrading your computer is a piece of cake – you don’t need to be a techie to do it. Just follow these three easy steps:
Step 1. Backup your data to another storage device
Step 2. Remove the old HDD from your computer
Step 3. Insert the A55 in your computer.

Ace A55 Bad Block Management for Higher Reliability

Bad Block Management for Higher Reliability

Even new disks can contain one or more bad blocks which may cause irreparable damage to your system. But have no fear! To prevent flash memory corruption, the A55 is built with bad block management technology. Bad blocks are continually monitored and replaced to keep your system in good condition and to improve reliability and endurance of the SSD. Because we do care about your data.The A55 applies ”SLC Cache technology” with a new caching architecture that combines both SLC and TLC flash blocks. This technology enables all data to be written in the SLC section before being sequentially copied to the TLC block, and as a consequence allows for higher peak writing performance.

Ace A55 Durability and Performance

Durability and Performance

Equipped with an original controller and 3D NAND flash, the A55 can not only guarantee stability and durability. It also delivers outstanding performance which enables 10-second quick boot-ups, shorter application load times and faster data transmission speed. Whether you are web surfing, enjoying a good movie, or have to handle paperwork, the A55 will bring you a smooth, lag-free experience.

Ace A55 Light and S.M.A.R.T.

Light and S.M.A.R.T.

The A55 is one of the lightest and thinnest SSDs of its kind yet it is shock- and vibration-proof, because it contains no moving parts. Equipped with a S.M.A.R.T. monitoring system and ECC (error correction code) technology, it also promises higher data transmission safety.

Ace A55 Internal Auto-Copy Technology

Internal Auto-Copy Technology

The A55’s auto-copy technology allows automatic copy operations from the SLC cache to the TLC blocks inside the NAND without using the controller or DDR. This supports higher efficiency by reducing the controller’s and DRAM’s workload.
