Silicon Power A55 4 TB Serial ATA III NVMe 3D NAND (SP004TBSS3A55S25)

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 Ace A55 is able to boot your computer or launch applications within seconds.


Durability and Performance
Equipped with an original controller and 3D NAND flash, the Ace 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 Ace A55 will bring you a smooth, lag-free experience.

Bad Block management (BBM)
A bad block management (BBM) mechanism detects and marks bad blocks to avoid storage in those blocks and eliminate access errors. And, even if errors do occur in new blocks during an erase, this mechanism can move the data to other effective blocks to prevent data loss resulting from the failed erase.


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


Internal Auto-Copy Technology
The Ace A55's auto-copy technology allows automatic copy operations from the SLC cache to the 3D NAND Flash inside the NAND without using the controller or DDR. This supports higher efficiency by reducing the controller's and DRAM's workload.
