Silicon Power Blaze B20 128 GB — Matt Black
128 GBCapless retractable connectorBuilt-in strap hole5-year warranty
The Silicon Power Blaze B20 (SP128GBUF3B20V1K) is a 128 GB USB-A flash drive with a capless, thumb-push retractable connector — Silicon Power calls it true protection against cap loss — in a matt black case with a diamond-cut pattern on the front cover that resists fingerprints and scratches. It runs USB 3.2 Gen 1, backwards compatible with USB 3.0 and USB 2.0, has a built-in strap hole for a keychain or bag, and carries a five-year warranty. It measures 55.0 × 20.0 × 8.6 mm and weighs 13 grams.
Compatibility — check before buying:
Silicon Power publishes no read or write speed for the Blaze B20 at any capacity — both rows are empty in its own specification table — so there is no figure to compare it on. What is published is the interface, the mechanism and the build. The part number is one digit-swap from a different drive: SP128GBUF3B02V1K is the Blaze B02, which Silicon Power does not describe as retractable, while this B20 is the capless retractable one. Both are black, both 128 GB, both USB-A — order by the full code. It is USB Type-A only; the Blaze range has no USB-C models, and Silicon Power’s USB-C drives are the separate Mobile C series. Two specifications Silicon Power publishes for its other Blaze drives but not for this one: the housing material and the storage temperature. We do not borrow them.
Best For

Key Features
Capless retractable connector
The USB plug slides out under your thumb and retracts into the body afterwards. Silicon Power’s own phrase is true protection against cap loss — there is nothing separate to leave behind on someone else’s desk.
Built-in strap hole
A strap hole moulded into the body so the drive attaches to a keychain or a bag. Combined with the retracting plug, it is a drive designed to be carried rather than kept in a drawer.
Matt finish with a diamond-cut cover
A matt outer case with a diamond-cut pattern on the front, which Silicon Power states resists fingerprints and scratches. At 8.6 mm thick it is slim enough not to crowd the port beside it.
Free SP Widget software
A free download offering backup and restore, AES 256-bit file encryption and cloud storage. The encryption runs on your computer rather than on the drive — there is no security controller in this product.

Frequently Asked Questions
Singular Expert Insight
Within Silicon Power’s Blaze range the B20 is the one that gets the mechanism right: a retracting plug, a strap hole and a matt finish that does not show every fingerprint, all at 8.6 mm so it does not foul the port next to it — a real complaint about the thicker B50. What none of the Blaze drives give you is a published transfer speed, and the B20 is no exception; both rows are empty in Silicon Power’s own table. So this is a purchase made on build, on the five-year warranty and on the shape, not on a benchmark. The ordering hazard is the B02, one digit-swap away and not a retractable drive. Tell us whether the mechanism or the speed matters more and we will point you accordingly.
Buyer’s Guide
Buy it if
You want a capless retractable 128 GB drive with a strap hole and a five-year warranty, and you are not choosing between drives on published MB/s figures.
Skip it if
You need a stated transfer speed, you need USB-C for a phone or a modern laptop, or you need the housing material and storage temperature published for a specification.
Also consider
The Silicon Power Blaze B02 for a plainer, lighter drive in the same range, or a Kingston DataTraveler Kyson if published read and write speeds are what you need.
