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.

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.

Not Recommended 8/2/2020 1:18:45 PM

Pros: Inexpensive.

Cons: Died 4 hours after it was installed in a PC. Hooked up to other computers, some of them see the SSD by the name of the Silicon Motion controller inside and with a 1021 MB capacity. I put back in the computer the 12 years old WD 1 TB HDD that still works fine, despite having over 50,000 hours of power-on time and over 300,000 load/unload cycles.

Overall Review: In the last several years, SSD manufacturers engaged in a race to the bottom in terms of quality. SLC NAND and MLC NAND were replaced by TLC, QLC, and now PLC, less and less reliable. I've got two SSDs die within 3 weeks of each other, in two different PCs, both with TLC NAND, one of them being the well reviewed Crucial MX500, less than 2 years old. Folks, if you value your data, don't bother to buy consumer level SSDs. If you must have SSD please buy an expensive enterprise unit, otherwise buy an electro-mechanical HDD, they are much more reliable, some of them are fast enough for almost any application, and before they die they give sufficient signs that will allow you to save most of the data. I have hard drives from 1996 that still work without issues. Don't let the SSD manufacturers take you hard earned money in exchange for trash.

Great product fair price 7/27/2020 10:57:55 PM

Pros: I was looking to upgrade the system and I always wind up coming back to Newegg cuz you usually have what I want at a fair price. After doing much searching I find that whatever way it comes up it comes up better for me from you and I just want to say thanks

Cons: I don't have any cons because every time I do business with Newegg it's very professional the prices are fair the times that I've had to call customer support it was excellent and that hasn't been very many times so again I say thank you

Overall Review: The overall review of this and all the products that I've gotten from Newegg have been fantastic and I'd like to say again thank you please keep up the good work and it's an honor to do business with you. Terry Hamilton

It works better than expected 7/25/2020 8:26:43 AM

Pros: Fast. Uses very little power. Easy to install using a 2.5" to 3.5" tray.

Cons: It took seven (7) hours to clone my 7200 RPM hard disk. I used Macrium Reflect as recommended by several people. No idea why this was the case.

Overall Review: MY PC is using Windows 10 Pro. I use it for a variety of chores including video and music editing. I created my own security suite with a virus scanner and firewall from different manufacturers. The system has always run solidly but too up to 15 minutes to settle down after a cold start or restart. Some applications were sluggish starting. Using the Silicon Power 1TB SSD, the system is completely up in just over two minutes. This may sound slow to some, but considering what I'm running at startup, it is orders of magnitude better than when my boot device was a 7200 RPM hard disk. I did make some changes to my system configuration. I split off most of the data to a second hard disk. The SSD has the operating system, all the application software, and some data. Performance is outstanding. I didn't know anything about Silicone Power and its products. After reading up on the company and sifting through reviews, I decided to give it a shot. I'm very happy I did. My experience has been 100% positive, except for the long time cloning my hard drive. But, since that was a one-time thing I won't take away any eggs. The ACE A-55 is a top notch drive that lives up to its specifications. I would recommend it highly.
