Affordable Upgrade for Everyone

Bring new life to your tired PC for far less cost than you would expect with the Silicon Power A55 SSD, which is positioned as one of the most cost-effective high-performance SSD models. Featuring advanced SATA III 6Gbps interface and implementing 3D NAND flash, it provides higher performance and greater stability and durability than HDDs. With support for SLC Caching, DRAM Cache Buffer, and auto-copy technology, it provides higher efficiency and longer lifespan. It's equipped with S.M.A.R.T. monitoring system and ECC (error correction code) technology for superior data transmission safety. It also employs bad block management technology to prevent flash memory corruption, ensuring maximum reliability. The Silicon Power's free-download software (SP Toolbox) lets you easily monitor your new SSD's health.

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 6GBps interface, the 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 A55 can not only guarantee stability and durability, but also delivers outstanding performance which enables 10-second quick boot-ups, shorter application load times and faster data transmission speed. Whether you are surfing the web, enjoying a good movie, or handling paperwork, the A55 will bring you a smooth, lag-free experience.

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 an S.M.A.R.T. monitoring system and ECC (error correction code) technology, it also promises higher data transmission safety.

SLC Cache Technology

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. The A55 also uses "DRAM buffer cache" to improve overall performance and to reduce write amplification on the TLC portion. This leads to enhanced endurance and a longer lifespan of the SSD.

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.

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.

Free-Download of SSD Health Monitor - SP Toolbox

Easily monitor your new SSD's health with Silicon Power's free-download software - SP Toolbox. Run performance tests on the A55, get an overall function evaluation, or check detailed information about your device, including used space, device temperature, total bytes written, and many more.

An Upgrade as Easy as 1-2-3

With a great cost-performance ratio, the A55 definitely is an excellent choice for those who want to experience a clear PC upgrade. Upgrading 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 S55 in your computer.

Low cost, Nice performance! 7/11/2020 7:30:29 AM

Average to good performance.

Cons: Not a brand most people think of when looking form SSD storage.

Overall Review: I'm always looking for lower cost alternative to the big name SSD manufacturers, as I'm always upgrading or building PC's for family, friends, and co-workers. I had never purchased an SP brand SSD, so wasn't sure what to expect. It has a solid quality build, and installed without any issues. I've been running a couple of 1TB SSD's in systems, and haven't had any issues with performance, compatibility or longevity. I have trouble shoveling out money for some of the over-priced options out there, when these products do exactly the same thing!!!

Drive failed, terrible customer service. 7/3/2020 4:29:34 PM

Overall Review: Look elsewhere for a drive. The original failed, and the replacement they sent me isn't even recognized by SP's own drive utility, Toolbox. Yet SP expects me to accept that drive as a fulfillment of their warranty. Save yourself a headache and look elsewhere for a drive.

The details: When my original 480GB drive failed under warranty, SP sent me a 512GB unit as a replacement. But there is a problem with the replacement drive - it shows up as "Device Not Found" in SP's own drive utility, Toolbox.

When I reported the problem to SP, rather than sending me a drive that can be detected by their own utility, SP told me they think there might be a problem in their Toolbox utility related to the model name, and that their engineers "are working on it". They later told me they'll let me know "if" the problem is solved.

So I'm stuck with a replacement drive that is useless, since it isn't even detected by SP's own reliability utility. SP claims the problem is a software glitch in the utility, but how can I know that is true? All I know is that the drive isn't detected by SP's own utility. Who would trust their data to a drive that isn't even detected by the company's own utility?

And yet SP has forced me to accept such a drive as fulfillment of their warranty obligation. As I say, look elsewhere.
