P\u00ebrve\u00e7 t\u00eb gjitha k\u00ebtyre, FlashLink p\u00ebrfshin dy komponente t\u00eb r\u00ebnd\u00ebsishme \u2014 Wear Leveling dhe Global Garbage Collection. K\u00ebto meritojn\u00eb nj\u00eb v\u00ebmendje t\u00eb ve\u00e7ant\u00eb.<\/p>\n

Praktikisht \u00e7do memorie e ngurt\u00eb \u00ebsht\u00eb nj\u00eb sistem ruajtjeje i miniaturizuar, me nj\u00eb num\u00ebr t\u00eb madh bllokesh dhe nj\u00eb kontrollues q\u00eb siguron aksesin n\u00eb t\u00eb dh\u00ebna. Kjo arrihet gjithashtu duke transferuar t\u00eb dh\u00ebnat nga qelizat \"t\u00eb d\u00ebmtuara\" n\u00eb ato \"t\u00eb pad\u00ebmtuara\". K\u00ebshtu garantohet mund\u00ebsia p\u00ebr t'i lexuar ato. Ekzistojn\u00eb algoritme t\u00eb ndryshme p\u00ebr k\u00ebt\u00eb transferim. N\u00eb p\u00ebrgjith\u00ebsi, kontrolluesi p\u00ebrpiqet t\u00eb balancoj\u00eb konsumimin e t\u00eb gjithave qelizave t\u00eb memories. Ky qasje ka nj\u00eb munges\u00eb. Kur n\u00eb brend\u00ebsi t\u00eb SSD ndodhin l\u00ebvizje t\u00eb t\u00eb dh\u00ebnave, numri i operacioneve t\u00eb hyrjes-daljes q\u00eb realizohet zvog\u00eblohet ndjesh\u00ebm.
