SanDisk SanDisk Extreme 256GB microSDXC UHS-I U3 V30 A2 160MB/s Read Memory Card
SanDisk Extreme 256GB is a microSDXC UHS-I memory card supplied with an SD adapter. The exact SDSQXA1-256G-GN6MA model carries Class 10, U3, V30 and A2 ratings, with manufacturer transfer figures of up to 160 MB/s read and 90 MB/s write. The 256GB capacity combines high removable-storage space with a performance profile intended for demanding capture and transfer workloads in compatible devices.U3 and V30 are separate sustained-performance classes: U3 is the UHS Speed Class 3 rating, while V30 is Video Speed Class 30. A2 is the Application Performance Class and does not represent a sequential transfer speed. The published 160 MB/s read and 90 MB/s write figures therefore remain separate specifications. Together these ratings distinguish this Extreme generation from SanDisk Ultra cards and from later Extreme revisions with different maximum speeds.SanDisk positions this card for 4K UHD video, high-resolution capture, action cameras and drones when the host supports microSDXC. It is specified as water-, shock-, temperature- and X-ray-resistant, and the package includes an SD adapter. Actual transfer rates depend on the host, reader and workload, so the figures are maximum rated speeds. The exact SKU is defined by its 256GB capacity, UHS-I interface and U3/V30/A2 profile.

SanDisk SanDisk Ultra 64GB microSDXC UHS-I U1 A1 Up to 100MB/s Read Memory Card
SanDisk Ultra 64GB is a microSDXC UHS-I memory card supplied with an SD adapter. The exact SDSQUAR-064G-GN6MA SKU carries Class 10, U1 and A1 ratings and is specified for read transfers of up to 100 MB/s. The 64GB capacity expands storage in compatible microSDXC devices, while the adapter lets the same card be inserted into supported full-size SD slots without changing its underlying format.Class 10 and U1 identify sustained-speed classes, while A1 is an Application Performance Class intended for supported app workloads. These markings are separate from the manufacturer's maximum read-transfer claim and should not be used to invent an unlisted write speed. This distinction is important when comparing SanDisk Ultra revisions because later cards can share the same capacity while carrying different published read speeds or packaging.SanDisk positions this Ultra model for compatible Android devices and Full HD video storage. Actual transfer performance depends on the device, reader, file pattern and workload, and the quoted 100 MB/s value is a maximum rather than a guaranteed result in every host. This listing is tied to SDSQUAR-064G-GN6MA and its 64GB microSDXC, UHS-I, Class 10, U1 and A1 specification, not to a newer Ultra generation.

Toshiba EXCERIA N302 128GB is a full-size SDXC memory card using the UHS-I interface. The exact THN-N302R1280E4 model carries Class 10 and U3 ratings and is specified for read performance of up to 90 MB/s. Its 128GB capacity provides removable storage for compatible SDXC cameras and other devices, with the N302 series positioned for photo and video capture where consistent card performance matters.U3 is the UHS Speed Class 3 rating, while Class 10 is the conventional SD speed class. These symbols express sustained-performance requirements and are separate from Toshiba's stated maximum read speed of 90 MB/s. No maximum write figure is added because it is not consistently confirmed for this exact SKU in the available specification sources. Keeping those fields separate avoids assigning a write speed from a similar EXCERIA generation.The standard 24 mm wide SD format means this is a full-size card rather than microSD, and the host must support SDXC media and 128GB capacity. Actual transfer speed depends on the camera, card reader, file size and workload, so the published read rate is a maximum. This listing identifies the Toshiba THN-N302R1280E4 by its EXCERIA N302 series, capacity, SDXC format, UHS-I bus and confirmed U3/Class 10 ratings.

Kingston 256GB is a full-size SDXC memory card using the UHS-I interface. Manufacturer part number SDA10/256GB identifies this exact capacity in Kingston's Class 10 UHS-I range, with rated transfer performance of up to 90 MB/s read and 45 MB/s write. The 256GB capacity provides substantial removable storage for compatible SDXC cameras and other hosts while retaining the standard full-size SD card format.Class 10 is the card's sustained-speed classification, while the published 90 MB/s read and 45 MB/s write values are separate maximum transfer figures. UHS-I identifies the bus used by the card and should not be confused with the speed class. These details are especially important for discontinued or older Kingston ranges, where similar packaging and names can hide different controller generations, capacities or performance specifications.Actual performance depends on the host device, reader, file sizes and workload, so the maximum transfer figures are not guaranteed in every system. A device must support SDXC media and the card's capacity to use it correctly. This listing therefore anchors the product to the SDA10/256GB part number, 256GB SDXC format, UHS-I interface and confirmed 90/45 MB/s performance rather than borrowing data from another Kingston SD card.

Kingston 128GB microSDXC is a UHS-I memory card identified by manufacturer part number SDC10G2/128GBSP. This exact model carries Class 10 and U1 ratings and is specified for transfer speeds of up to 45 MB/s read and 10 MB/s write. The 128GB capacity provides removable storage in compatible microSDXC devices without changing the card's original microSD form factor.UHS-I is the interface generation, while U1 and Class 10 are sustained-performance classifications. Kingston's 45 MB/s read and 10 MB/s write figures are separate maximum transfer specifications, so they should not be inferred from the class symbols themselves. This matters for an older card such as the SDC10G2 series because neighbouring Kingston products can use similar naming while offering different speeds, capacities or package contents.Kingston specifies resistance to water, shock, vibration, X-rays and temperature extremes for this card family, supporting everyday use and transport. Actual performance depends on the host device, reader, file pattern and workload, and a compatible microSDXC slot is required for the 128GB SDXC capacity.

Samsung EVO Plus 32GB is a microSDHC memory card using the UHS-I interface. The exact MB-MC32D/EU SKU is rated Class 10 and U1, with manufacturer transfer figures of up to 80 MB/s read and 20 MB/s write. An SD adapter is supplied with this version, allowing the microSD card to be used in compatible full-size SD slots while the storage device itself remains microSDHC.The combination of 32GB capacity, UHS-I bus and U1/Class 10 performance is the defining specification of this earlier EVO Plus generation. Class 10 and U1 indicate sustained-speed classes; they are not substitutes for the separate maximum read and write figures. That distinction helps avoid confusing this card with later EVO Plus revisions carrying higher advertised transfer speeds or different capacity ranges.Samsung positions the card for compatible smartphones, tablets, cameras and Full HD recording, and specifies protection against water, temperature extremes, X-rays, magnetic fields and shock. Actual transfer rates vary with the host, reader and workload, while the included adapter does not change the card's underlying microSDHC format or performance class.

UHS-I is also the card bus, so a host must support the SDXC format and appropriate interface to make use of the card as intended.Samsung designed this EVO card with protection against water, X-rays and magnetic fields, helping protect stored data during normal transport and use. Actual transfer speed still depends on the host device, card reader, file size and workload, so the stated read figure should be treated as the manufacturer's maximum rather than a guaranteed rate in every system.

SanDisk SanDisk Extreme 128GB SDXC UHS-I Class 10 U3 V30 90MB/s Write Memory Card
The SanDisk Extreme 128GB is a SDXC memory card using the UHS-I interface. This exact SKU carries the Class 10 U3 V30 ratings. Manufacturer-rated transfer performance reaches up to 180 MB/s read and 90 MB/s write, while the 128GB capacity provides removable flash storage.Class 10 identifies the conventional SD speed-class tier; U3 is the UHS Speed Class 3 rating; and V30 is its Video Speed Class. These markings are separate specifications and should not be substituted for one another. V30 is the confirmed Video Speed Class, while U3 is the UHS Speed Class.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.
