Xa abathengi bethenga iimveliso ze-OPS, baya kufumanisa ukuba kukho iintlobo ezimbini zee-hard drives: i-SSD kunye ne-HDD. Yintoni i-SSD kunye ne-HDD? Kutheni i-SSD ikhawuleza kune-HDD? Ziziphi izinto ezingeloncedo kwi-SSD? Ukuba unale mibuzo, nceda uqhubeke ufunda.

Iidrayivu ezinzima zahlulwe zibe ziidrive zoomatshini (i-Hard Disk Drive, i-HDD) kunye ne-slid state drives (SSD).

I-hard disk yomatshini yidiski enzima yemveli kunye neqhelekileyo, ikakhulu yenziwe: ipleyiti, intloko yemagnethi, iplatter shaft kunye namanye amalungu. Njengoko kunye nesakhiwo soomatshini, i

isantya semoto, inani leentloko zemagnethi, kunye noxinaniso lwepleyiti konke kunokuchaphazela ukusebenza. Ukuphucula ukusebenza kwe-HDD hard disks ikakhulu kuxhomekeke ekwandiseni isantya sokujikeleza, kodwa isantya esiphezulu sokujikeleza sithetha ukwanda kwengxolo kunye nokusetyenziswa kwamandla. Ke ngoko, ubume be-HDD bumisela ukuba kunzima ukutshintsha ngokusemgangathweni, kwaye izinto ezahlukeneyo ziyanciphisa ukuphuculwa kwayo.

I-SSD luhlobo lokugcina oluye lwavela kwiminyaka yamuva, igama elipheleleyo liyi-Solid State Drive.

Ineempawu zokufunda nokubhala ngokukhawuleza, ubunzima obulula, ukusetyenziswa kwamandla aphantsi kunye nobukhulu obuncinci. Ekubeni akukho ngxaki enjalo ukuba isantya sokujikeleza asinakunyuswa, ukuphuculwa komsebenzi wayo kuya kuba lula kakhulu kune-HDD. Ngeenzuzo zayo ezinkulu, iye yaba yeyona nto iphambili kwimarike.

Ngokomzekelo, i-random read latency ye-SSD yizishumi ezimbalwa ze-millisecond, ngelixa i-random read latency ye-HDD ijikeleze i-7ms, kwaye ingaba phezulu njenge-9ms.

Isantya sokugcinwa kwedatha ye-HDD malunga ne-120MB / S, ngelixa i-SSD ye-SATA protocol malunga ne-500MB / S, kunye nesantya se-SSD ye-NVMe protocol (PCIe 3.0 × 4) malunga ne-3500MB / S.

Xa kuziwa kwizicelo ezisebenzayo, ngokubhekiselele kwiimveliso ze-OPS (zonke-in-one machine) zichaphazelekayo, zombini i-SSD kunye ne-HDD inokuhlangabezana neemfuno zokugcinwa ngokubanzi. Ukuba ulandela isantya esikhawulezayo kunye nokusebenza okungcono, kuyacetyiswa ukuba ukhethe i-SSD. Kwaye ukuba ufuna umatshini wohlahlo lwabiwo-mali, i-HDD iya kufaneleka ngakumbi.

Ihlabathi lonke li-digitizing, kwaye imidiya yokugcina ilitye lembombo yokugcina idatha, ngoko ukubaluleka kwabo kunokucingelwa. Kukholelwa ukuba ngophuhliso lobugcisa, kuya kubakho iimveliso ezikumgangatho ophezulu kunye neendleko ezifanelekileyo ukuhlangabezana neemfuno ezingcono. Ukuba unayo nayiphi na imibuzo malunga nokukhetha uhlobo lwe-hard drive, nceda uqhagamshelane nathi!
