Lexar launches $50 USB Type-C CFexpress card reader with speeds up to 1,050MB/s

06 Jun

Lexar has announced its upcoming Lexar Professional CFexpress USB 3.1 Reader, a budget-friendly CFexpress card reader that offers impressive speeds in a compact package.

The Lexar Professional CFexpress USB 3.1 Reader is based on the USB 3.1 Gen 2 Type-C interface and can deliver read speeds up to 1,050MB/s through its CFexpress Type B card slot. It measures in at roughly 5.6cm x 4.7cm x 1.3cm (1.1” x 1.5” x .14”), weighs just 21g (0.74oz) and can operate between -10°C to 70°C (14°F to 158°F) if you really feel like putting it to the test.

Despite having a USB Type-C host port on the reader, Lexar opted to only include a USB Type-C to USB Type-A cable within the box. So, if you’re wanting a USB Type-C to USB Type-C connection, you’ll need to supply your own cable.

The good news is, this omission likely plays a role in the affordability of this card reader. The Lexar Professional CFexpress USB 3.1 Reader is currently available to pre-order for just $ 50 (Adorama, B&H). At this time, it appears to be the cheapest CFexpress card reader from major brands, including SanDisk ($ 70), Sony ($ 100), ProGrade ($ 100), Delkin ($ 55) and even Wise ($ 59).

USB4 gets official with maximum 40Gb/s bandwidth, USB Type-C connection

04 Sep

The USB Implementers Forum (USB-IF) has published the specifications for USB4, the next-generation USB architecture first teased back in March 2019.

USB4 will be a ‘major update’ that builds on the existing USB 3.2 and USB 2.0 architectures. It will be based on Intel Corperation’s Thunderbolt protocol specification and will double ’the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols,’ according to the announcement.

The USB-IF says USB4 is backwards compatible with USB 2.0, USB 3.2 and Thunderbolt 3, and will feature a maximum speed of up to 40Gb/s, twice the current 20Gb/s maximum. Since it will be using the same USB Type-C connection, manufacturers won’t need to alter designs to use the new ports. USB Power Delivery will also be a requirement in USB4 devices.

Despite the specification being finalized, it’ll likely take some time to market. Historically, it’s taken roughly a year from the time the specifications have been released to the time we see it in the first devices, but it’s always possible that precedent could be broken.
