Ngenkathi uthenga i-laptop entsha, kungenzeka ukuthi ubonile abantu bephikisana ngokuthi idivayisi ene- I-HDD ingcono noma enye ene-SSD . Yini i-HDD lapha? Sonke siyazi nge-hard disk drive. Kuyidivayisi yokugcina izinto eziningi esetshenziswa ngokujwayelekile kuma-PC, amalaptop. Igcina isistimu yokusebenza nezinye izinhlelo zohlelo lokusebenza. I-SSD noma i-Solid-State drive iyindlela entsha ye-Hard Disk Drive evamile. Ingene emakethe muva nje esikhundleni se-hard drive, obekuyidivayisi eyinhloko yokugcina abantu abaningi iminyaka eminingana.
Nakuba umsebenzi wabo ufana nowe-hard drive, awakhiwe njengama-HDD noma asebenze njengawo. Lo mehluko wenza ama-SSD ahluke futhi anikeze idivayisi izinzuzo ezithile nge-hard disk. Sazise okwengeziwe ngama-Solid-State Drives, ukwakheka kwawo, ukusebenza kwawo, nokunye okuningi.

Iyini i-Solid-State Drive (SSD)?
Siyazi ukuthi inkumbulo ingaba yezinhlobo ezimbili - eguquguqukayo futhi engaguquguquki . I-SSD iyidivayisi yokugcina engaguquguquki. Lokhu kusho ukuthi idatha egcinwe ku-SSD ihlala ngisho nangemva kokuba ugesi umisiwe. Ngenxa yokwakheka kwazo (zenziwe yisilawuli se-flash kanye ne-NAND flash memory chips), amadrayivu e-solid-state abuye abizwe ngokuthi ama-flash drive noma ama-solid state disks.
Ama-SSD – Umlando omfushane
Amadrayivu e-hard disk ayesetshenziswa kakhulu njengemishini yokugcina iminyaka eminingi. Abantu basasebenza kumadivayisi ane-hard disk. Ngakho-ke, yini ephushe abantu ukuthi bacwaninge enye insiza yokugcina izinto eziningi? Ama-SSD aba khona kanjani? Ake sihlole umlando ukuze sazi isisusa esisemuva kwama-SSD.
Ngawo-1950s, bekusetshenziswa ubuchwepheshe obu-2 obufana nendlela ama-SSD asebenza ngayo, okungukuthi, inkumbulo eyinhloko kazibuthe kanye nesitolo sokufunda kuphela se-capacitor yekhadi. Nokho, ngokushesha zanyamalala ngenxa yokutholakala kwezindawo ezishibhile zokugcina imigqomo.
Izinkampani ezinjenge-IBM zasebenzisa ama-SSD kumakhompiyutha azo amakhulu okuqala. Kodwa-ke, ama-SSD ayengasetshenziswa njalo ngoba ayemba eqolo. Kamuva, ngawo-1970, idivayisi ebizwa ngokuthi i-Electrical Alterable I-ROM yenziwe ngabakwaGeneral Instruments. Nalokhu akuzange kuhlale isikhathi eside. Ngenxa yezinkinga zokuqina, le divayisi nayo ayizange ithole ukuduma.
Ngonyaka we-1978, i-SSD yokuqala yasetshenziswa ezinkampanini zikawoyela ukuthola idatha yokuzamazama komhlaba. Ngo-1979, inkampani StorageTek yathuthukisa i-RAM SSD yokuqala ngqa.
RAM Ama-SSD asekelwe asetshenziswa isikhathi eside. Nakuba ayeshesha, asebenzisa izinsiza eziningi ze-CPU futhi ayebiza kakhulu. Ekuqaleni kuka-1995, ama-SSD asekelwe ku-flash athuthukiswa. Kusukela kwethulwa ama-SSD asekelwe ku-flash, izinhlelo zokusebenza ezithile zemboni ezidinga okuhlukile I-MTBF (isikhathi esimaphakathi phakathi kokuhluleka) isilinganiso, esikhundleni sama-HDD kwafakwa ama-SSD. Amadrayivu e-Solid-state ayakwazi ukumelana nokushaqeka okukhulu, ukudlidliza, ukushintsha kwezinga lokushisa. Ngakho bangakwazi ukusekela okunengqondo Imali yokuthengisa ye MTBF.
Asebenza kanjani ama-Solid State Drives?
Ama-SSD akhiwa ngokunqwabelanisa ama-memory chips axhumene kugridi. Ama-chips enziwe nge-silicon. Inombolo yama-chips kusitaki iyashintshwa ukuze kuzuzwe ukuminyana okuhlukile. Ngemva kwalokho, afakwa ama-transistors esango antantayo ukuze abambe ukushaja. Ngakho-ke, idatha egciniwe igcinwa kuma-SSD ngisho nalapho enqanyuliwe emthonjeni wamandla.
Noma iyiphi i-SSD ingaba neyodwa ye- izinhlobo ezintathu zenkumbulo - amaseli eleveli eyodwa, amaleveli amaningi noma amathathu.
eyodwa. Amaseli ezinga elilodwa ashesha kakhulu futhi ahlala isikhathi eside kuwo wonke amaseli. Ngakho, abiza kakhulu futhi. Lezi zakhelwe ukuze zibambe idatha eyodwa nganoma yisiphi isikhathi.
ezimbili. Amaseli anamazinga amaningi ingabamba izingcezu ezimbili zedatha. Ngesikhala esinikeziwe, bangabamba idatha eningi kunamaseli eleveli eyodwa. Kodwa-ke, banesimo esingalungile - ijubane labo lokubhala lihamba kancane.
3. Amaseli anamazinga amathathu zishibhe kakhulu kulenkatho. Azihlali isikhathi eside. Lawa maseli angabamba amabhithi edatha angu-3 kuseli eyodwa. Babhala isivinini yisona esihamba kancane.
Kungani kusetshenziswa i-SSD?
Ama-Hard Disk Drives bekuyidivayisi yokugcina ezenzakalelayo yamasistimu, isikhathi eside. Ngakho-ke, uma izinkampani zishintshela kuma-SSD, mhlawumbe kunesizathu esihle. Manje ake sibone ukuthi kungani ezinye izinkampani zithanda ama-SSD emikhiqizweni yawo.
Ku-HDD yendabuko, unamamotho okuphotha ucwecwe, futhi ikhanda le-R/W liyanyakaza. Ku-SSD, ukugcinwa kunakekelwa ama-flash memory chips. Ngakho, azikho izingxenye ezihambayo. Lokhu kuthuthukisa ukuqina kocingo.
Kumalaptop anama-hard drive, idivayisi yokugcina izodla amandla engeziwe ukuze ijikeleze uqweqwe. Njengoba ama-SSD engenazo izingxenye ezihambayo, amalaptop anama-SSD adla amandla amancane uma kuqhathaniswa. Ngenkathi izinkampani zisebenzela ukwakha ama-HDD ayingxube asebenzisa amandla amancane ngenkathi ephotha, lawa madivayisi ayingxube cishe azodla amandla amaningi kune-solid-state drive.
Nokho, kubukeka sengathi ukungabi nazo izingxenye ezihambayo kuza nenqwaba yezinzuzo. Futhi, ukungabi namapuleti okuphotha noma amakhanda e-R/W anyakazayo kusho ukuthi idatha ingafundwa kudrayivu cishe ngaso leso sikhathi. Ngama-SSD, ukubambezeleka kuncipha kakhulu. Ngakho, amasistimu anama-SSD angasebenza ngokushesha.

Ama-HDD adinga ukuphathwa ngokucophelela. Njengoba zinezingxenye ezihambayo, ziyazwela futhi zintekenteke. Ngezinye izikhathi, ngisho nokudlidliza okuncane okuvela ethonsini kungalimaza I-HDD . Kepha ama-SSD anesandla esiphezulu lapha. Angakwazi ukumelana nomthelela kangcono kunama-HDD. Kodwa-ke, njengoba benenani elilinganiselwe lemijikelezo yokubhala, banesikhathi sokuphila esinqunyiwe. Agcina engasasebenziseki uma imijikelezo yokubhala isiphelile.
Izinhlobo zama-SSD
Ezinye zezici zama-SSD zithonywa uhlobo lwawo. Kulesi sigaba, sizoxoxa ngezinhlobo ezahlukahlukene zama-SSD.
eyodwa. 2.5 - Uma kuqhathaniswa nawo wonke ama-SSD ohlwini, lena ihamba kancane. Kodwa isashesha kune-HDD. Lolu hlobo lutholakala ngentengo engcono kakhulu nge-GB ngayinye. Iwuhlobo oluvame kakhulu lwe-SSD olusetshenziswa namuhla.
ezimbili. mSATA - m imele mini. Ama-mSATA SSD ashesha kunawodwa angu-2.5. Zikhethwa kumadivayisi (njengamakhompyutha aphathekayo namabhukwana) lapho isikhala singeyona into ewubukhazikhazi. Banesici esincane sefomu. Ngenkathi ibhodi lesifunda ku-2.5 livaliwe, lawo aku-mSATA SSD angenalutho. Uhlobo lwabo lokuxhuma nalo luyahluka.
3. I-SATA III - Lokhu kunoxhumo oluthobelana kokubili i-SSD ne-HDD. Lokhu kwaduma lapho abantu beqala ukushintshela ku-SSD besuka ku-HDD. Ijubane layo elincane lika-550 MBps. Idrayivu ixhunywe ebhodini le-motherboard kusetshenziswa intambo ebizwa ngokuthi ikhebula le-SATA ukuze ibe minyene kancane.
Ezine. I-PCIe - I-PCIe imele i-Peripheral Component Interconnect Express. Leli igama elinikezwe indawo evamise ukugcina amakhadi ezithombe, amakhadi emisindo, nokunye okunjalo. Ama-PCIe SSD asebenzisa lesi sikhala. Ashesha kakhulu kunawo wonke futhi ngokwemvelo, abiza kakhulu futhi. Bangakwazi ukufinyelela isivinini esicishe siphindwe kane kunesika-a Ukushayela kwe-SATA .
5. M.2 - Njengamadrayivu e-mSATA, anebhodi lesifunda elingenalutho. Amadrayivu e-M.2 ngokwenyama amancane kunazo zonke izinhlobo ze-SSD. Lezi zilala kahle ngokumelene nebhodi lomama. Anephinikhodi encane yokuxhuma futhi athatha isikhala esincane kakhulu. Ngenxa yobuncane bazo, zingashisa ngokushesha, ikakhulukazi uma ijubane liphezulu. Ngakho-ke, beza ne-heatsink/heat spreader eyakhelwe ngaphakathi. Ama-M.2 SSD ayatholakala kukho kokubili i-SATA kanye Izinhlobo ze-PCIe . Ngakho-ke, amadrayivu e-M.2 angaba osayizi abahlukahlukene nesivinini. Nakuba i-mSATA kanye namadrayivu angu-2.5 engakwazi ukusekela i-NVMe (esizoyibona ngokulandelayo), amadrayivu e-M.2 angakwazi.
6. I-NVMe - I-NVMe imele I-Non-Volatile Memory Express . Leli gama libhekisela kusixhumi esibonakalayo ngama-SSD afana ne-PCI Express kanye nedatha yokushintshisana ye-M.2 nomsingathi. Nge-interface ye-NVMe, umuntu angafinyelela isivinini esikhulu.
Ingabe ama-SSD angasetshenziswa kuwo wonke ama-PC?
Uma ama-SSD unokuningi angakunikeza, kungani bengakawashintshi ngokugcwele ama-HDD njengethuluzi lokulondoloza eliyinhloko? Okubalulekile okuvimba lokhu yizindleko. Yize intengo ye-SSD manje isincane kunalokho ebiyikho, lapho ingena emakethe, Ama-HDD aseyinketho eshibhile . Uma kuqhathaniswa nenani le-hard drive, i-SSD ingabiza cishe kathathu noma kane ngaphezulu. Futhi, njengoba ukhulisa umthamo wedrayivu, intengo ikhuphuka ngokushesha. Ngakho-ke, akukabi yinketho yezezimali yazo zonke izinhlelo.

Esinye isizathu esenza ama-SSD angawashintshi ngokugcwele ama-HDD umthamo. Isistimu evamile ene-SSD ingaba namandla ebangeni le-512GB ukuya ku-1TB. Nokho, sesivele sinezinhlelo ze-HDD ezinama-terabytes amaningana okugcina. Ngakho-ke, kubantu ababheka amandla amakhulu, ama-HDD aseyinketho yawo yokuya kuwo.
Ukulinganiselwa
Siwubonile umlando wokuthuthukiswa kwe-SSD, ukuthi i-SSD yakhiwe kanjani, izinzuzo ezinikezayo, nokuthi kungani ingakasetshenziswa kuwo wonke ama-PC/laptops okwamanje. Kodwa-ke, yonke into emisha kwezobuchwepheshe iza nesethi yayo yezinkinga. Yibuphi ububi be-solid-state drive?
eyodwa. Isivinini sokubhala - Ngenxa yokungabikho kwezingxenye ezihambayo, i-SSD ingakwazi ukufinyelela idatha ngokushesha. Nokho, ukubambezeleka kuphela okuphansi. Uma idatha kufanele ibhalwe kudiski, idatha yangaphambilini idinga ukusulwa kuqala. Ngakho, imisebenzi yokubhala ihamba kancane ku-SSD. Umehluko wesivinini ungase ungabonakali kumsebenzisi ojwayelekile. Kodwa kuwukungalungi lapho ufuna ukudlulisa amanani amakhulu wedatha.
ezimbili. Ukulahleka kwedatha kanye nokutholwa - Idatha esusiwe kumadrayivu e-solid-state ilahleka unomphela. Njengoba ingekho ikhophi yedatha eyenziwe isipele, lokhu kuwububi obukhulu. Ukulahlekelwa unomphela kwedatha ebucayi kungaba into eyingozi. Ngakho-ke, iqiniso lokuthi umuntu akakwazi ukubuyisela idatha elahlekile ku-SSD ngomunye umkhawulo lapha.
3. Izindleko - Lokhu kungaba umkhawulo wesikhashana. Njengoba ama-SSD ewubuchwepheshe obusha kakhulu, kungokwemvelo ukuthi ayabiza kune-HDD evamile. Sibonile ukuthi amanani abelokhu ehla. Mhlawumbe eminyakeni embalwa, izindleko ngeke zibe yisithiyo sokuthi abantu bashintshele kuma-SSD.
Ezine. Ubude bempilo - Manje sesiyazi ukuthi idatha ibhalwa kudiski ngokusula idatha yangaphambilini. Yonke i-SSD inenani elimisiwe lemijikelezo yokubhala/yokwesula. Ngakho-ke, njengoba usondela kumkhawulo womjikelezo wokubhala/usula, ukusebenza kwe-SSD kungase kuthinteke. I-SSD evamile iza nemijikelezo yokubhala/yokwesula engaba ngu-1,00,000. Le nombolo elinganiselwe yenza kube mfushane ukuphila kwe-SSD.
5. Isitoreji - Njengezindleko, lokhu kungase futhi kube umkhawulo wesikhashana. Kusukela manje, ama-SSD atholakala kuphela ngomthamo omncane. Kuma-SSD wamakhono aphezulu, umuntu kufanele akhiphe imali eningi. Isikhathi kuphela esizosho ukuthi singakwazi yini ukuba nama-SSD athengekayo anomthamo omuhle.
