Lapho amakhasimende ethenga imikhiqizo ye-OPS, azothola ukuthi kunezinhlobo ezimbili zama-hard drive: i-SSD ne-HDD. Iyini i-SSD ne-HDD? Kungani i-SSD ishesha kune-HDD? Yibuphi ububi be-SSD? Uma unale mibuzo, sicela uqhubeke ufunda.

Amadrayivu aqinile ahlukaniswe ngamadrayivu aqinile emishini (Hard Disk Drive, HDD) kanye namadrayivu wesimo esiqinile (SSD).

I-hard disk engumshini iyi-hard disk yendabuko nevamile, ikakhulukazi eyakhiwe: ucwecwe, ikhanda kazibuthe, i-platter shaft nezinye izingxenye. Njengesakhiwo semishini, i

isivinini semoto, inani lamakhanda kazibuthe, nokuminyana kwepuleti kungathinta ukusebenza. Ukuthuthukisa ukusebenza kwama-hard disks e-HDD ikakhulukazi kuncike ekwandiseni isivinini sokujikeleza, kodwa isivinini esikhulu sokuzungeza sisho ukwanda komsindo nokusetshenziswa kwamandla. Ngakho-ke, isakhiwo se-HDD sinquma ukuthi kunzima ukushintsha ngekhwalithi, futhi izici ezihlukahlukene zikhawulela ukuthuthukiswa kwayo.

I-SSD iwuhlobo lwesitoreji oluvele eminyakeni yamuva nje, igama layo eliphelele yi-Solid State Drive.

Inezici zokufunda nokubhala ngokushesha, isisindo esincane, ukusetshenziswa kwamandla okuphansi kanye nosayizi omncane. Njengoba kungekho nkinga enjalo ukuthi isivinini sokujikeleza asikwazi ukunyuswa, ukuthuthukiswa kokusebenza kwayo kuzoba lula kakhulu kune-HDD. Ngezinzuzo zayo ezinkulu, isiphenduke inkambiso emakethe.

Isibonelo, ukubambezeleka kokufunda okungahleliwe kwe-SSD kuyingxenye yeshumi nje embalwa ye-millisecond, kuyilapho ukubambezeleka kokufunda okungahleliwe kwe-HDD kucishe kube ngu-7ms, futhi kungase kuphakame njengokungu-9ms.

Ijubane lokugcina idatha le-HDD lilinganiselwa ku-120MB/S, kuyilapho ijubane le-SSD yephrothokholi ye-SATA lilinganiselwa ku-500MB/S, kanti isivinini se-SSD se-NVMe protocol (PCIe 3.0×4) silinganiselwa ku-3500MB/S.

Uma kukhulunywa ngezinhlelo zokusebenza ezisebenzayo, mayelana nemikhiqizo ye-OPS (umshini ohlanganisa konke) kokubili i-SSD ne-HDD ingahlangabezana nezidingo ezijwayelekile zokulondoloza. Uma uphishekela isivinini esisheshayo nokusebenza okungcono, kunconywa ukuthi ukhethe i-SSD. Futhi uma ufuna umshini webhajethi, i-HDD izofaneleka kakhulu.

Umhlaba wonke wenza idijithali, futhi imidiya yokugcina iyitshe legumbi lokugcina idatha, ngakho ukubaluleka kwayo kungacatshangwa. Kukholakala ukuthi ngokuthuthukiswa kobuchwepheshe, kuzoba nemikhiqizo eminingi futhi esezingeni eliphezulu futhi engabizi kakhulu ukuhlangabezana nezidingo kangcono. Uma unemibuzo mayelana nokukhetha uhlobo lwe-hard drive, sicela usithinte!
