Gjetja e \u00e7do disku solid-state \u00ebsht\u00eb nj\u00eb sistem i ruajtjes n\u00eb miniatur\u00eb, me num\u00ebr t\u00eb madh blokesh dhe nj\u00eb kontrollues, i cili siguron disponueshm\u00ebrin\u00eb e t\u00eb dh\u00ebnave. Kjo sigurohet, p\u00ebrfshir\u00eb p\u00ebrmes faktit q\u00eb t\u00eb dh\u00ebnat nga 'qelizat e prishura' transferohen n\u00eb 'qelizat e paprishura'. K\u00ebshtu, garanton q\u00eb ato do t\u00eb mund t\u00eb lexohen. Ekzistojn\u00eb algoritme t\u00eb ndryshme p\u00ebr k\u00ebt\u00eb transfer. N\u00eb rrafshin e p\u00ebrgjithsh\u00ebm, kontrolluesi p\u00ebrpiqet t\u00eb balancoj\u00eb konsumimin e t\u00eb gjitha qelizave t\u00eb diskut. Ky qasje ka nj\u00eb disavantazh. Kur brenda SSD ndodhin l\u00ebvizje t\u00eb t\u00eb dh\u00ebnave, numri i operacioneve t\u00eb input-output d\u00ebshmuesh\u00ebm zvog\u00eblohet.

Prandaj, n\u00ebse sistemi ka shum\u00eb disqe solid-state, n\u00eb grafik\u00ebn e performanc\u00ebs s\u00eb tij shfaqet nj\u00eb 'sawtooth', me ngritje dhe ulje t\u00eb papritura.

Fatmir\u00ebsisht, si kontrollet n\u00eb disqe ashtu edhe kontrollet e ruajtjes, dhe mikroprogrami te Huawei jan\u00eb 'origjinale', k\u00ebto procese n\u00eb OceanStor Dorado 18000 V6 nisin qendrorisht, nj\u00ebkoh\u00ebsisht n\u00eb t\u00eb gjitha disqet e arrays.
