firmware update

Storage devices may incorporate wear leveling transparently as part of the storage controller logic, in which case this problem is taken care of by the storage device manufacturer. This is the case for most mid- to high-end storage devices. For example, all SD cards have a storage controller that takes wear leveling into account.

Many cheaper or older storage devices do not have wear leveling built in, however, and then wear leveling should be handled at the operating system level. This type of storage is often referred to as "raw flash", and in Linux it makes use of the Memory Technology Device (MTD) subsystem to implement wear leveling.

When working with raw flash devices, Unsorted Block Images (UBI) (which is similar in purpose to Logical Volume Manager (LVM)) and UBIFS can be used to implement wear leveling.
