Ama-Flash Drives ayimithombo ethandwa kakhulu yokugcina yangaphandle. Ngokungafani nama-disk ama-optical kanye nama-disk (i-CD / DVD kanye nokushayela kanzima, ngokulandelana), ama-drive drive ane-compact more futhi ayamelana nomonakalo wemishini. Futhi ngenxa yokuthi yikuphi ukuzwana nokuqina okutholakele? Ake sibheke!
Ngabe i-drive drive iqukethe kanjani futhi kanjani
Into yokuqala okufanele uyiqaphele ukuthi azikho izingxenye zemishini ezihambayo ngaphakathi kwe-flash drive ezingathinteka ngokuwa noma ukushaqeka. Lokhu kutholakala ngenxa yomklamo - ngaphandle kwecala lokuzivikela, i-flash drive iyibhodi lesifunda eprintiwe lapho isixhumi se-USB sithengiswa. Ake sibheke izakhi zalo.
Izakhi eziyinhloko
Izingxenye zokushayela okuningi kwe-flash zingahlukaniswa zibe yizisekelo nelesibili.
Okusemqoka kufaka phakathi:
- Ama-memory we-NAND chips;
- isilawuli
- i-quartz resonator.
- Imbobo ye-USB
Inkumbulo ye-NAND
I-drive isebenza ngokubonga kwimemori ye-NAND-memory: chips ze-semiconductor. Ama-chip ememori enjalo, okokuqala, acwebile kakhulu, futhi okwesibili, anamandla amakhulu kakhulu: uma ekuqaleni ama-drive drive alahlekelwe umthamo wamadiski e-optical ayejwayelekile ngaleso sikhathi, manje ngisho namadiski e-Blu-Ray adlula umthamo. Imemori enjalo, phakathi kwezinye izinto, nayo ayisiqobelo, okungukuthi, ayidingi mthombo wamandla ukugcina imininingwane, ngokungafani ne-RAM chips eyenziwe ngobuchwepheshe obufanayo.
Noma kunjalo, inkumbulo ye-NAND ine-drawback eyodwa ngokuqhathaniswa nezinye izinhlobo zamadivayisi wokugcina. Iqiniso ngukuthi impilo yenkonzo yalezi zipi ikhawulelwe inombolo ethile yemijikelezo yokubhala kabusha (izinyathelo zokufunda / ukubhala imininingwane esitokisini). Ngokwesilinganiso, inani lemijikelezo yokufunda ukubhala ingama-30,000 (kuya ngohlobo lwe-memory chip). Lokhu kubukeka njengesixa esimangalisayo, kepha empeleni kuyinto ecishe ibe yiminyaka emi-5 yokusebenzisa kanzima. Noma kunjalo, noma ngabe umkhawulo ufinyelelwe, i-flash drive ingaqhubeka isetshenziswe, kodwa kuphela ekufundeni idatha. Ngaphezu kwalokho, ngenxa yemvelo yayo, inkumbulo ye-NAND isengozini enkulu yokuphelelwa amandla nokukhishwa kwamandla kagesi, ngakho-ke gcina kude nemithombo yezingozi ezinjalo.
Isilawuli
Inombolo 2 kwisibalo esisekuqaleni kwendatshana iyisicokhethi esincane - isilawuli, ithuluzi lokuxhumana phakathi kwenkumbulo ye-flash namadivayisi axhunyiwe (ama-PC, amathelevishini, imisakazo yemoto, njll.).
Isilawuli (ngenye indlela esibizwa ngokuthi yi-microcontroller) iyikhompyutha yokuqala yesimanje eneprosesa yayo nenani elithile le-RAM elisetshenziselwa ukulondolozwa kwedatha nezinjongo zensizakalo. Inqubo yokuvuselela i-firmware noma i-BIOS isho nje ukubuyekeza i-software ye-microcontroller. Njengoba umkhuba ukhombisa, umonakalo ojwayelekile kakhulu kumashayeli we-flash ukwehluleka kwesilawuli.
I-Quartz crystal
Le ngxenye ikristalu elincanyana le-quartz, okuthi, njengewashi likagesi, kukhiqize ama-oscillations ahambelana nobunye bemvamisa ethile. Ku-drive drive, i-resonator isetshenziselwa ukuxhumana phakathi kwesilawuli, inkumbulo ye-NAND nezinye izinto ezengeziwe.
Le ngxenye ye-flash drive nayo isengozini yomonakalo, futhi, ngokungafani nezinkinga nge-microcontroller, cishe akunakwenzeka ukuzixazulula ngokwakho. Ngenhlanhla, ekushayeleni kwesimanje, ama-resonators ahluleka ngokweqile
Isixhumi se-USB
Esikhathini esiningi samacala, kuzishayeli zanamuhla zama-flash, kufakwa isixhumi sohlobo lwe-USB 2.0 A, kugxilwe ekwamukeleni nasekudluliseleni. Abashayeli abasha kakhulu basebenzisa i-USB 3.0 Type A no-Type C.
Izinto ezengeziwe
Ngaphezu kwezingxenye eziyinhloko zedivaysi yememori ye-flash eshiwo ngenhla, abakhiqizi bavame ukubanikeza ngezinto zokuzikhethela, njengesikhombisi se-LED, iswitshi esivikela ukubhala, nezinye izici ezithile kumamodeli athile.
Isikhombi se-LED
Amashayeli amaningi we-flash anama-LED amancane kodwa akhanya kahle. Yakhelwe ukubonisa ngamehlo umsebenzi we-flash drive (ukuqopha noma ulwazi lokufunda) noma kumane kuyinto yokuqamba.
Lesi sikhombisi sivame ukungathathi umthwalo olusebenzayo we-flash drive uqobo, futhi siyadingeka, empeleni, sisebenzela umsebenzisi noma ubuhle.
Bhala isivikelo sokuvikela
Le nto ivame kakhulu amakhadi we-SD, yize kwesinye isikhathi itholakala kumadivayisi wokugcina we-USB. Lezi zokugcina zivame ukusetshenziswa endaweni yebhizinisi njengabathwali bolwazi oluhlukahlukene, kubandakanya okubalulekile nokuyimfihlo. Ukugwema izehlakalo ngokususwa ngephutha kwedatha enjalo, abakhiqizi bama-drive Drives kwezinye amamodeli basebenzisa inkinobho yokuvikela: i-resistor, okuthi lapho ixhumeke kwisekethe yokuhambisa amandla kagesi, ivimbele amandla kagesi ekufinyeleleni amaseli ememori.
Uma uzama ukubhala noma ususa imininingwane esuka ku-drive lapho kuvikelwe khona ukuvikelwa, i-OS izowubonisa lowo myalezo.
Ngokufanayo, ukuvikela kuyasetshenziswa ezinkingeni ezibizwa nge-USB: ama-flash drive aqukethe izitifiketi zokuphepha ezidingekayo ukuze kusetshenziswe kahle isoftware ethile.
Le nto nayo ingaphuka, kuholele esimweni esicasulayo - idivaysi ibonakala isebenza, kepha akunakwenzeka ukuyisebenzisa. Sinezinto esizeni lethu ezingasiza ekuxazululeni le nkinga.

Izakhi ezihlukile
Lokhu kufaka, ngokwesibonelo, ukuba khona kwe-Lightning, i-microUSB noma i-Type-C izixhumi: ama-flash drive ngokubakhona kwalawa enzelwe ukusetshenziswa, kufaka phakathi ama-Smartphones kanye namathebulethi.

Kukhona ukushayela okuvikeleke kakhulu kwemininingwane erekhodiwe - kunekhibhodi eyakhelwe ngaphakathi yokufaka iphasiwedi yedijithali.
Eqinisweni, lena inguqulo esezingeni eliphakeme kakhulu yesishini sokuvikela esingaphezulu esishiwo ngenhla.
Izinzuzo zokushayela kwe-flash:
- ukuthembeka;
- umthamo omkhulu;
- ukubumbana;
- ukumelana nokucindezelwa kwemishini.
Ubunzima bokushayela kwe-flash:
- fragility yezakhi ezakhiwayo;
- impilo yenkonzo ekhawulelwe;
- ukuba sengozini kokwehla kwamandla kagesi nokukhishwa okuyisisekelo.
Ukufingqa - ngokubuka endaweni yezobuchwepheshe, i-drive drive iyinkimbinkimbi impela. Kodwa-ke, ngenxa yokwakhiwa okuqinile kwesifundazwe nokukhiqizwa kwe-miniaturization yezakhi, ukumelana okukhulu ekucindezelekeni kwemishini kuyatholakala. Ngakolunye uhlangothi, ama-drive drive, ikakhulukazi anedatha ebalulekile, kumele avikeleke emiphumeleni yama-voltage surges noma kagesi we-tuli.
