Silicon Power Ace A55 1TB Internal SSD
1TB2.5" SATA III 6Gb/sUp to 500MB/s3D NAND + SLC cache
The Silicon Power Ace A55 1TB, part number SP001TBSS3A55S25, is an affordable internal 2.5-inch SATA III solid state drive with reads up to 500MB/s, made as a simple, reliable upgrade for desktops and laptops. It uses 3D NAND flash with SLC caching to keep everyday performance responsive at a budget-friendly price.
With sequential reads up to 500MB/s and writes up to 450MB/s, the Ace A55 is dramatically faster than a mechanical hard drive for boot, application loading and general use. Carrying EAN 4712702659139 and MPN SP001TBSS3A55S25, it fits any device with a 2.5-inch SATA bay and includes data-protecting features such as ECC and bad block management. Typically in stock with fast delivery across Cyprus.
Compatibility note
The Ace A55 is a standard 2.5-inch 7mm SATA III drive that fits virtually all laptops and desktops with a SATA bay, and is backward compatible with SATA 3Gb/s. It is not an M.2 or NVMe drive and will not fit M.2 slots. This is a value-focused DRAM-less design and does not include hardware encryption.
Best For
✓ Affordable upgrades from a hard drive
✓ A faster boot and OS drive on a budget
✓ Everyday computing, web, office and study
✓ Adding 1TB of fast secondary storage
✓ Photo, document and media libraries
✓ Quiet, shock-resistant storage with no moving parts
Key Features
SLC caching for responsiveness
An SLC cache combined with 3D NAND lets data write quickly to a fast cache first, boosting peak performance for everyday tasks.
Speeds up to 500MB/s
The SATA III 6Gb/s interface delivers reads up to 500MB/s and writes up to 450MB/s, far quicker than a mechanical hard drive for boot and loading.
Tough and durable
With no moving parts, the Ace A55 is shock-resistant and more reliable against bumps and drops than a hard drive, running cool and silent.
Data protection built in
ECC error correction, bad block management, garbage collection and S.M.A.R.T. monitoring help protect your data and maintain performance.

Frequently Asked Questions
Will the Silicon Power Ace A55 1TB fit my laptop or desktop?
Yes, in most cases. It is a standard 2.5-inch SATA III drive with a 7mm height that fits the vast majority of laptops and desktop SATA bays. It will not fit M.2 or NVMe slots, so confirm your device has a 2.5-inch SATA connector before buying.
Is the Ace A55 fast enough for everyday use?
Yes. With reads up to 500MB/s it is far faster than any hard drive and makes boot, app loading and general use feel much more responsive. It is a value SATA SSD aimed at mainstream everyday computing rather than heavy professional workloads.
How does the Ace A55 compare to an NVMe SSD?
The Ace A55 is a 2.5-inch SATA drive capped at around 500MB/s, ideal for systems with only a SATA bay. An M.2 NVMe drive such as the Kingston NV3 reaches several thousand MB/s but needs an M.2 NVMe slot. Choose the Ace A55 when your device does not support M.2 NVMe.
What do I need to know before buying the Ace A55 1TB?
Confirm your system has a free 2.5-inch SATA bay and a way to clone or reinstall your operating system. It is a DRAM-less 3D NAND drive with SLC caching, a 1,500,000-hour MTBF and a 3-year limited warranty; it does not include hardware encryption.
Singular Expert Insight
The Silicon Power Ace A55 is a budget value SATA SSD that nails the basics: turning a slow hard-drive system into a responsive one cheaply, with SLC caching to keep everyday tasks snappy. It is a sensible pick for a low-cost upgrade or secondary storage. If you want higher speed, a longer warranty or a DRAM cache for steadier sustained writes, the Transcend SSD230S or Kingston KC600 are worth the step up, and if your system has an M.2 slot an NVMe drive will be far faster.

Buyer's Guide
Buy it if
You want the cheapest way to add SSD speed to a laptop or desktop, a budget boot drive, or 1TB of 2.5-inch SATA storage for everyday use.
Skip it if
Your device has an M.2 NVMe slot (NVMe is far faster), you want higher speed or a longer warranty, or you need hardware encryption.
Also consider
Transcend SSD230S or WD Blue SA510 for a 5-year warranty and faster speed, the Kingston KC600 for DRAM + encryption, or the Kingston NV3 NVMe for M.2 systems.
