Can your device handle 32GB or larger cards?
There may be issues with SDHC-compatible devices not handling cards that are 32Gb or larger. This may result in the device refusing to mount the card (make it accessible to its operating system for storage) or file-system activities may take a long time to complete.
This may be rectified through an operating system or firmware update for your computer or device. In the case of computers, it may be worth checking the online update program for drivers or middleware that can do this job. For devices such as smartphones, check for “field-deployable” firmware updates that can allow the device to properly work with large SD cards.
There may be a limitation with devices that don’t work with a field-update procedure for their firmware and, in some cases, the manufacturer may not revise the firmware at all through the device’s lifespan. These situations may limit your ability to work with the large cards and you may have to wait for newer models to come out to take advantage of them.
Use beyond smartphones
Achieving a small neat nice design for portable equipment without forfeiting capacity
The 32Gb MicroSDHC card may also yield a valid reason for camera manufacturers to implement MicroSD cards in smaller camera designs when they equip these devices with high-resolution still or video capabilities.
This could similarly benefit handheld audio equipment like “digital notetakers” and personal media players where there is a desire to store a high quantity of higher-quality recordings yet achieve a pocketable design.
Similarly, manufacturers could cram more circuitry or room for batteries into other portable devices like portable GPS units without forfeiting storage capacity.
A compact solid-state storage alternative to the 2.5” SSD.
The SD card technology is optimised as a random storage medium in a similar way to the hard disk or the classic floppy disks. In this case, the microSDHC card can be used as a compact solid-state storage medium which is occasionally removed.
For example, a 32Gb microSDHC hidden behind a service panel could be useful as a system drive (boot, operating system, applications, hibernate file and registry) in a laptop or notebook computer with a regular 2.5” hard disk being used for user data. For printers and all-in-one devices, this card would work as a larger temporary storage for applications like keeping the print or fax queue for reliable and convenient printer operation.
The main reason I am blogging on the 32GB MicroSDHC card is because it is an example of the direction that solid-state secondary storage is taking, whether in a removeable or fixed form
