Silicon Power A55 512GB M.2 SATA SSD Review

In the past few months, we’ve notice a rise in popularity of M.2 PCIE SSDs, such as the Silicon Power P34A60, which we reviewed last month. However having said that, many computers may not support this form factor, with some motherboards lacking the necessary M.2 PCIe slots. What’s even more annoying is the fact that the only PCIe slot on your motherboard is already occupied, then we have no choice but to decide on an M.2 SATA drive.

For those users who need fast but inexpensive M.2 SATA SSD, Silicon Power designed the A55 series, which will be presented in this review. In tests, we have a 512GB version of the A55 SSD. This capacity is probably the most popular because of the price and enough space for daily work.

Stay with us to check how much to offer has the A55 512GB SSD from Silicon Power.


Ultra-Compact for Up-to-Date Devices

Designed with M.2 2280 form factor (80 × 22 x 3.5 mm), compact-sized and case-less A55 M.2 2280 SSD perfectly fits into tiny-and-thin devices such as ultrabooks, tablet computers and mini PCs.


Enhanced Performance for Intensive Workloads

Equipped with high-quality synchronous NAND flash chips and SATA III 6 Gb/s interface, the A55 M.2 2280 offers impressive transfer rates of up to 560/530 MB/sec read/write. So if you need an instant upgrade solution for everyday computing applications or multitasking demands, the A55 is your perfect solution. Its intelligent SLC cache technology can boost writing performance to even higher peaks – for transfer rates at lightning speed!

Intel®SRT Supported for Flexible Configuration

Not only fast, also smart! Intel® Smart Response Technology (ISRT) enables flexible computer configuration for improved overall performance and efficiency. It automatically identifies and stores your most frequently used applications to the SSD, while leaving your hard drive full of storage capacity. Ah! So you can combine a small-capacity SSD with a high-capacity HDD and enjoy an upgrade solution that won’t cost you an arm and a leg. (Mind you, you still need them, especially your arm for operating your upgraded, super-fast computer….)

For Peace of Mind – Guaranteed Reliability and Stability

The A55 M.2 2280 supports TRIM, NCQ and S.M.A.R.T. command. It also ensures stability and overall system reliability with built-in automatic error correction (ECC), average rewriteable storage block technology (Wear Leveling) and bad block management.
