Kuhle Imininingwane yenethiwekhi. SSD Yikuphi ukukhetha?

Ngokuvamile, abantu abaningi babheka izindlela ukwandisa isivinini kanye nokusebenza PC yakho. Ngalokhu, ngokuvamile libhekisela ukuthenga processor kanye ihluzo ikhadi elisha, okwandisa inani RAM, ukusheshisa zonke izingxenye, nokunye. Kodwa abantu abaningi bayakhohlwa ukubaluleka disk hard, ngoba isivinini sokufinyelela olwazini inkomba sasivumela owawubalulekile PC ngesivinini. Lokukhipha kulesi simo ukuthenga SSD-drive, esikhundleni ezivamile HDD-ngemoto. Ake sibone ukuthi yini uhlobo SSD futhi ukhethe ukuthi yini kulo mhlahlandlela.

Konke emashalofini

1. Kwasekuqaleni, kukhethwa SSD-drive kudingeka ukuba banake lo mbhalo futhi kufundwa disc. Singasho ukuthi lena lokuma zonke nama-hard drive. Zama ukuthenga SSD-drive lekufa eliphakeme.
2. Isibalo IOPS - input bese okukhipha yedatha ngomzuzwana. Ngokwemvelo, ayanda inombolo inkomba kahle ukusebenza idrayivu nge esiningi idatha. Uma idiski enjalo ukufaka uhlelo lokusebenza, izoqala ukuba ngokoqobo "fly".
3. Isilawuli - ngumgogodla idrayivu. Ukukhetha isilawuli ngeke kuwuphendule umbuzo ophathelene nendlela ukukhetha SSD-drive ngokugcwele. It Kunconywa ukunikeza abakukhethayo njengoba isiqinisekiso: Intel, SandForce futhi Marvell. idatha abalawuli nomkhiqizi the ningi NEMPUMELELO NGAPHAKATHI, isikhathi eside futhi ngempumelelo.
4. Kuyadingeka ukuthola ncamashí ukuhlelwa, ngeke esibonakalayo idatha kanjani. Namuhla emakethe elandelayo izinhlobo akhona akhona: SATAII, SATAIII futhi PCIe. Sekuyisikhathi eside Eyokuqala kwaba yisikhathi, ukuze iqembu lakhe ngisho ukubukela. Esesibili - ukhetho ezifanele kakhulu uma ungathandi lokudlela nge ukufakwa abashayeli okunye okujabulelayo. Interface PCIe kudinga ukufakwa abashayeli ezifanele, kuba ukuba bazikhandle kakhudlwana ohlelweni, kodwa it ithumba konke on the fly. Lona isixazululo ngokushesha kunazo zonke, omunye zikhathi belinganisa we SSD ukukhetha.
5. I chips inkumbulo. Ezimakethe kukhona izinhlobonhlobo ezilandelayo: MLC futhi SLC. Indlela yesibili ezibizayo nokunye okuningi, kodwa ukusebenza kwalo kaningana. Kodwa ngaphansi evamile ukusetshenziswa MLC chips ukuphila kwabo inkonzo ingahlala iminyaka engu-4-5. Lokhu akuyona njengoba iphuzu elibalulekile indlela ukukhetha SSD-drive, uma kuqhathaniswa, isibonelo, nge isilawuli. Kodwa sikhethe inkumbulo chips kusadingeka ukunquma.
6. Ukuba khona imisebenzi eyengeziwe ezifana ECC, SMART, SIKA, okuvumela ukusetshenziswa drive likhona isikhathi eside. Lezi imisebenzi ungakwazi usule amadiski ngothuli, zihlanganisa ukuwohloka-yokululama ubuchwepheshe ukuhlinzeka ulwazi mayelana nesimo se-disk, nokunye.
7. Umthamo, ikakhulukazi SSD, kuthinta kakhulu intengo. Kunconywa ukuthenga disc ephethe namandla 70-90 GB. Inani sediski kuyadingeka ukuze usebenze ekuphenduleni umbuzo ngalokho ukukhetha SSD.
8. MTBF - mangaki amahora Imininingwane izothatha drive. Ayanda MTBF, isikhathi eside umsebenzi idrayivu. Ngokuvamile, leli nani ma-iri ama kwezigidi ezingu 2.1.

Sebenzisa theory ukuzijayeza

Ungafuni ukuthenga imodeli eqolo, benaka ngokukhethekile izici kuphela abese eqala ukubuza intengo. Iphendula umbuzo "kanjani ukukhetha SSD", kumele ukuthi uma wosesho omuhle, ungathola kukho olukhulu at an ngentengo eqolo. Into esemqoka - ungakhohlwa, yiziphi izici okudingeka ukuba siqondiswe ngesikhathi esifanayo.
