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.

Great little drive 8/12/2020 6:16:25 PM

Pros: Inexpensive
As fast as other, more expensive drives

Cons: Not free?

Overall Review: Works as expected, I had to replace a customer's SSD on a tight budget, and a Silicon Power SSD fit the bill. It worked well, and there's been no issues in many months. I caught a couple of these on sale, and had no reservations in buying them. 128GB is a bit small, but they will be perfect for current and future mining rigs.

Connector in slightly the wrong place! 8/8/2020 3:41:39 AM

Pros: Was an amazing speed boost for an old laptop. Seems to work OK now that it's in place.

Cons: The drive's sata connector refused to seat in the slot on the laptop. I tried other drives and they dropped right in. Close comparison with another SSD showed that the sata connector was slightly offset, and the tight confines of the slot did not allow any flexibility in positioning. I actually had to use a file to take some material off the side of the drive (a millimeter or so). Once I did this, it did drop in and connect properly, though of course one of the screw holes no longer aligned correctly.

Overall Review: I don't know what to make of this. How can a factory, churning out thousands upon thousands of sata drive cases, get this wrong?? Sata standards are not new, the world has been making this form factor for 10 years!

Good value, fast enough. 8/5/2020 4:39:39 PM

Pros: 1TB version:
- Not DOA
- Fast enough for secondary storage (where games get installed ;-)
- Good value.

Overall Review: Good enough speeds, at least in my case that I do not use it as main drive (OS is in another drive).
I have had another smaller drive from this brand for some years now so I decided to go with this one again.
Yes, it doesn´t have the best controller around and there are other minor technical disadvantages you can read about in the internet (do your homework), but as a data and games storage it is good enough for me. I just wish it is reliable, so far so good.

Good product. 8/3/2020 5:21:46 AM

Pros: The drive formatted for Mac as an external FireWire without issue. I was able to clone over an OS to the FireWire no problem and Boot from the FireWire.

Cons: I mounted the drive in my Apple Power Mac Dual G5 but the drive is not recognized. I tried both drive positions. I was hoping to be able to use as a boot drive in the G5. I was able to do this in the past with a Silicon Power S55 but the Silicon PowerA55 is not recognized.

Overall Review: I would only recommend for a more modern computer.
