SanDisk Extreme 128GB SDXC UHS-I Class 10 U3 Up to 90MB/s Read Memory Card

Description

The SanDisk Extreme 128GB is a SDXC memory card using the UHS-I interface. This exact SKU carries the Class 10 U3 ratings. Manufacturer-rated transfer performance reaches up to 90 MB/s read and 60 MB/s write, while the 128GB capacity provides removable flash storage.

Class 10 identifies the conventional SD speed-class tier; and U3 is the UHS Speed Class 3 rating. These markings are separate specifications and should not be substituted for one another.

Actual transfer rates depend on the host device, file pattern and workload, so quoted maximum figures are best treated as the card's rated ceiling rather than a guaranteed result in every system. Host equipment must support the same card format and, where applicable, the same bus standard to make use of the stated performance profile. The combination of capacity, format, interface and confirmed class markings is what distinguishes this exact model from neighbouring capacities and earlier or later revisions.

The specification deliberately separates read speed, write speed and class markings because each describes a different aspect of card performance.

    Returns & Delivery

    When will my order be delivered?

    Orders placed before 11:00 are usually dispatched the same working day. Orders placed after 11:00, or during weekends and public holidays, will be processed and dispatched on the next working day.

    After dispatch, the delivery time depends on the selected delivery service and the courier.

    Can I return my product?

    Yes, returns are accepted in accordance with our return policy and your statutory rights.

    Returned items should be complete, securely packed, and returned with all original accessories and packaging where possible. Once the item is received, it will be inspected before any refund or replacement is approved.

    For CPUs and other delicate electronic components, we check for physical or installation-related damage, including bent pins, damaged contact pads, socket damage, thermal paste contamination, missing parts, or other signs of incorrect installation, misuse, or handling damage.

    If the item has been damaged after delivery or used beyond what is necessary to inspect it, this may affect refund eligibility, and a deduction or refusal may apply where permitted by law.

    This does not affect your statutory rights if the item is faulty, not as described, or not fit for purpose.

    What can I do if my item (or part of it) is damaged?

    If your item arrives damaged, please contact us as soon as possible and send clear photos of the product, packaging, and damaged part.

    Please do not install, use, repair, or modify the item before contacting us. We will review the information and advise the next steps.

    Damage caused after delivery, including incorrect installation, bent CPU pins, damaged contact pads, socket damage, misuse, or other handling damage, may affect refund or replacement eligibility.

    This does not affect your statutory rights.
