Ama-SSD manje asebeka kancane kancane imishini yokushayela ejwayelekile. Uma muva nje, ama-SSD ayencane ngevolumu futhi, njengomthetho, asetshenziselwa ukufaka uhlelo, manje sekuvele kune-1 terabyte noma amadiski amaningi. Izinzuzo zokushayela okunjalo zisobala - kuthulile, ijubane eliphezulu nokuthembela. Namuhla sizonikeza izeluleko zokuthi ungayenza kanjani isinqumo esifanele se-SSD.
Amanye amathiphu wokukhetha i-SSD
Ngaphambi kokuthenga idiski entsha, kufanele unake inani lamapharamitha azokusiza ukhethe idivaysi efanelekile yohlelo lwakho:
- Nquma ngevolumu ye-SSD;
- Thola ukuthi yiziphi izindlela zokuxhuma ezitholakala kusistimu yakho;
- Naka "ukugxusha" kudiski.
Kungenxa yalezi zinhlaka esizokhetha idrayivu, ngakho-ke ake sibheke ngamunye wabo ngemininingwane eminingi.
Isikhala sediski
Ama-SSD ahlala isikhathi eside kunediski ejwayelekile, okusho ukuthi ngeke uyithengise isikhathi esingaphezu konyaka. Kungakho kufaneleka ukusondela ekukhetheni kwevolumu ngokuzibophezela ngokwengeziwe.
Uma uhlela ukusebenzisa i-SSD yohlelo nezinhlelo, kulokhu ke idrayivu eyi-128 GB ilungile. Uma ufuna ukumiselela ngokuphelele idiski ejwayelekile, khona-ke kuleli cala kufanelekile ukucubungula amadivaysi anomthamo we-512 GB noma ngaphezulu.
Ngaphezu kwalokho, ngokungathandeki ngokwanele, usayizi wediski uthinta impilo yenkonzo kanye nesivinini sokufunda / sokubhala. Iqiniso ukuthi ngenani elikhulu lesitoreji, isilawuli sinendawo eyengeziwe yokusabalalisa umthwalo kumaseli wememori.
Izindlela Zokuxhuma
Njenganoma iyiphi enye idivaysi, i-SSD kumele ixhunywe kwikhompyutha ukuze isebenze. Izindawo zokuxhumana ezivame kakhulu yi-SATA ne-PCIe. Ukushayela nge-PCIe kushesha kakhulu kunokushayela kwe-SATA futhi kuvame ukwenziwa ngendlela yekhadi. Ama-drive we-SATA abukeka emnandi ngokwengeziwe, futhi futhi ayindawo yonke, ngoba angakwazi ukuxhumana nekhompyutha kanye ne-laptop.
Kodwa-ke, ngaphambi kokuthenga idiski, kufanele uhlole ukuthi ngabe kukhona ama-PCIe noma ama-SATA Slots ebhodini lomama.
I-M.2 enye indlela yokuxhuma ama-SSDs angasebenzisa ibhasi le-SATA ne-PCI-Express (PCIe). Isici esiyinhloko sokushayela ngesixhumi esinjalo i-compactness. Sekukonke, kunezinketho ezimbili zesixhumi - ngokhiye B no-M Bahlukile ngenani lama- "cutout". Uma esimweni sokuqala (ukhiye B) kunokusikwa okukodwa, khona-ke kwesibili - kukhona amabili awo.
Uma siqhathanisa izindawo zokuxhuma ngejubane, khona-ke okusheshayo yi-PCIe, lapho isilinganiso sokudluliswa kwedatha singafinyelela ku-3.2 Gb / s. Kepha i-SATA - ifika ku-600 Mb / s.
Uhlobo lwenkumbulo
Ngokungafani nama-HDD ajwayelekile, ama-state state drive aqinile ayigcina kwimemori ekhethekile. Manje kwenziwa amadiski anezinhlobo ezimbili zale nkumbulo - i-MLC ne-TLC. Uhlobo lwenkumbulo olunquma insiza nejubane ledivayisi. Ukushayela ngohlobo lwememori ye-MLC kuzoba nokusebenza okuphezulu kakhulu, ngakho-ke kungcono ukuzisebenzisa uma kufanele ukopishe, ususe noma uhambise amafayela amakhulu. Kodwa-ke, izindleko zamadiski anjalo ziphakeme kakhulu.
Kumakhompyutha amaningi wasekhaya, ukushayela kwe-TLC kuhle. Ziphansi ngejubane le-MLC, kepha nokho ziphakeme kakhulu kumadivayisi wokugcina ajwayelekile.
Abakhiqizi be-Chip Abalawuli
Akuyona indima yokugcina ekukhetheni idiski edlalwa abenzi be-chip. Ngamunye wabo unezinzuzo nezithelo zakhe. Ngakho-ke, abalawuli abasuselwa kuma-SandForce chips athandwa kakhulu. Banezindleko eziphansi nokusebenza okuhle. Isici salawa mazwibela ukusetshenziswa kokucindezelwa kwedatha ngenkathi kuqoshwa. Kukhona futhi ukubuyisa okubalulekile - lapho idiski ligcwele ngaphezulu kwesigamu, ijubane lokufunda / lokubhala lehla kakhulu.
Ukushayela ngama-chips avela kuMarvel kunejubane elihle kakhulu, elingathinteki ngamaphesenti okugcwaliswa. Ukudonswa kuphela lapha yizindleko eziphakeme.
AbakwaSamsung futhi benzela ama-chips amadrayivu wombuso aqinile. Isici salokhu ukubethela ezingeni lehadiwe. Kodwa-ke, nazo zinenkinga. Ngenxa yezinkinga nge-algorithm yokuqoqa udoti, ijubane lokufunda / lokubhala lingancipha.
Ama-fizon chips abonakala ngokusebenza okuphezulu nezindleko eziphansi. Azikho izinto ezithinta ijubane, kepha ngakolunye uhlangothi, azizikhombisi kahle ngokubhala nokufunda ngokungakhethi.
I-LSI-SandForce ngomunye umenzi we-chip wabalawuli be-SSD. Imikhiqizo yalo mkhiqizi ijwayelekile impela. Enye yezinto ukucindezelwa kwedatha ngesikhathi sokudluliselwa ku-NAND Flash. Njengomphumela, inani lemininingwane erekhodiwe liyancishiswa, okuthi ekugcineni kulondoloze insiza yedrayivu ngqo. Okubi ngukuncipha kokusebenza komlawuli kumthwalo wememori ephezulu.
Futhi ekugcineni, umenzi we-chip wakamuva uyi-Intel. Ama-controller asuselwe kula ma-chips akhombisa ukusebenza okuhle kuzo zonke izinhlangothi, kodwa futhi abiza kakhulu kunamanye.
Ngaphezu kwabakhiqizi abaphambili, kukhona abanye. Isibonelo, kumamodeli wesabelomali sokushayela ungathola abalawuli ngokususelwa kuma-chips we-jMicron enza umsebenzi omuhle wemisebenzi yabo, yize ukusebenza kwalawa makhipi kuphansi kunakho konke.
Isilinganiso seDrayivu
Cabanga ngama-disc ambalwa ahamba phambili esigabeni sabo. Njengezigaba sithatha ivolumu ye-drive uqobo.
Amadiski afinyelela ku-128 GB
Izinhlobo ezimbili zingahlukaniswa kulesi sigaba. I-Samsung MZ-7KE128BW kumanani afinyelela kuma-ruble ayizinkulungwane ezingama-8000 futhi ashibhile Intel SSDSC2BM120A401, izindleko zazo ezahlukahluka kububanzi zisuka ku-4000 kuya kuma-ruble angama-5000.
I-Model Samsung MZ-7KE128BW ibonakala ngesivinini sokufunda / ukubhala okuphezulu esigabeni sayo. Ngenxa yomzimba omncane, kufanelekile ukufakwa kwi-ultrabook. Kungenzeka usheshise umsebenzi ngokwaba i-RAM.
Izici Key:
- Funda Ijubane: 550 Mbps
- Ijubane lokubhala: 470 Mbps
- Ijubane Lokufunda Okungahleliwe: 100,000 IOPS
- Ijubane Lokubhala: Okunga-90,000 IOPS
I-IOPS inombolo yamabhulokhi enesikhathi sokubhala noma sokufunda. Isikhombi lesi siphakeme, siphakeme ukusebenza kwensiza.
I-Intel SSDSC2BM120A401 ingenye ehamba phambili phakathi "kwabasebenzi bakahulumeni" abanamandla afinyelela ku-128 GB. Kubonakala ngokuthembela okuphezulu futhi kufanelekile ukufakwa kwi-ultrabook.
Izici Key:
- Funda Ijubane: 470 Mbps
- Ijubane lokubhala: 165 Mbps

Isiphetho
Ngakho-ke, sihlole izindlela eziningana zokukhetha i-SSD. Manje udinga nje ukujwayela okunikezwayo futhi, usebenzisa imininingwane etholakele, unqume ukuthi iyiphi i-SSD elungele wena nohlelo lwakho.
