Silicon Power Ace A55 2TB 2.5" SATA SSD
2TBSATA III 6Gb/sUp to 560MB/s3D NAND + SLC Cache
The Silicon Power Ace A55 2TB, part number SP002TBSS3A55S25, is a 2.5-inch SATA III internal SSD that offers a large amount of fast solid-state storage at an affordable price. It is an ideal upgrade for desktops and laptops, replacing a slow mechanical hard drive or adding a roomy second drive, using 3D NAND flash with an SLC cache for a responsive performance boost.
With sequential reads up to 560MB/s and writes up to 530MB/s, the A55 saturates the SATA III interface for a dramatic improvement over any hard drive. Carrying EAN 0886576037912 and MPN SP002TBSS3A55S25, it combines an SLC cache and DRAM cache buffer with a 1,500,000-hour MTBF and a 3-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The A55 uses the standard 2.5-inch 7mm form factor and SATA III interface, fitting almost every desktop and laptop with a 2.5-inch drive bay or SATA connection. It is backward compatible with SATA II. For thin laptops that only accept M.2 drives, choose an M.2 SSD instead.

Frequently Asked Questions
Will this fit my computer?
If your desktop or laptop has a 2.5-inch drive bay or a SATA connection — which covers most machines — the A55 will fit. It uses the standard 2.5-inch 7mm size. Only ultra-thin laptops limited to M.2 drives are an exception.
How much faster is it than a hard drive?
Dramatically faster. At up to 560MB/s versus around 100-150MB/s for a typical hard drive, you will see much quicker boot times, near-instant app launches and far faster file copying.
Is the A55 good value at 2TB?
Yes — the A55 is one of the most affordable ways to get 2TB of SSD storage. For everyday computing, gaming and media it feels essentially as responsive as pricier SATA drives, making it excellent value per gigabyte.
What is SLC cache and why does it matter?
SLC caching uses part of the flash as a high-speed buffer so frequent writes complete quickly, keeping the drive feeling fast during everyday use. Combined with a DRAM cache buffer, it boosts responsiveness on a budget SSD.
Singular Expert Insight
The Silicon Power Ace A55 is all about value: it delivers a big jump over any hard drive and plenty of capacity for the lowest price, making the 2TB a smart pick for bulk storage, an older PC or a budget build. As an entry-level SATA drive it is not aimed at sustained heavy workloads — for that, a TLC drive like the WD Blue SA510 offers a longer warranty — but for everyday use and large media libraries the A55 is hard to beat on price.

Buyer's Guide
Buy it if
You want the most affordable way to add 2TB of fast SATA SSD storage to a desktop or laptop, upgrading from a hard drive or adding a roomy second drive.
Skip it if
Your system supports M.2 NVMe (much faster for similar money), or you need a longer warranty and higher endurance for heavy, sustained write workloads.
Also consider
The WD Blue SA510 for a 5-year warranty, the A55 in other capacities, or a Crucial P310 / WD Blue SN5100 M.2 NVMe drive if your system has an M.2 slot.
