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.

Silicon Power 1/26/2020 5:10:32 PM

Pros: This is the second one of these that I have ordered. The first one has been running with no issues for over two years. I like the reliability so I purchased a second one for my sisters laptop. It is also working great so far.

Cons: n

Overall Review: The price point on these are what caused my to give them a try. They seem to be fine. I cannot say what the read write speeds are as I have not gauged them. Low price and sata II speed with reliability made me repeat.

Great Price quick shipping and easy replacement. 1/7/2020 9:21:04 AM

Pros: This is the second Silicon Power drive the first was smaller and about the same price as prices have come down.

Cons: none so far

Good for the price 1/5/2020 2:44:52 PM

Pros: Was on sale, so I got 256GB for the price of 128.

Cons: Not the fastest SSD, but definitely faster than HDD.

Overall Review: If I had more to spend I would have gotten 512GB or more. As it is, I'm filling it up fast. But since I'm strictly using it for games with long load times, it does the job.
