Kodi SSD? A chida chatsopano mu chitukuko cha umisiri mkulu

patsogolo luso mofulumira osauka. Pali zipangizo zatsopano kwambiri atsogolere moyo wa munthu masiku ano. Izi ndi zoona makamaka peripherals zosiyanasiyana kompyuta. Izi zipangizo zina zamakono amene anatuluka posachedwapa olimba boma abulusa. Yokhala watsopano media, mwinamwake kudziwika monga SSD, gwiritsani awiri mitundu kukumbukira: la NAND ndi RAM. Abulusa ndi chikumbukiro mtundu wachiwiri n'zochepa ndi ntchito mafomu zofuna kudya molimba pagalimoto ntchito. NAND-abulusa ndi zambiri zofanana. Izi mtundu wa kukumbukira ntchito mafoni zipangizo ndi ma PC chikhalidwe, kotero nkhaniyi ayankhidwa ndi NAND-abulusa.

Popeza kuti ndi SSD ndi momwe iwo amasiyana abulusa ochiritsira zovuta, sindidziwa onse. Panthawiyi Chachikulu kusiyana pakati pawo - kuwerenga ndi kulemba liwiro. SSD Izi kwambiri patsogolo pa ena onse atolankhani. Mwa dongosolo la galimoto boma olimba ndi mwapadera kwa galimoto mwakhama. Ngati otsiriza wakhala kusuntha mbali, ndi SSD ali ndi dongosolo monolithic amene amapereka pafupifupi chete ntchito laputopu kapena piritsi. Ndendende chimene mu abulusa olimba boma mulibe kuwerenga mutu amapereka otsika mowa mphamvu ndi mkulu liwiro kuwerenga, komanso kukula yaing'ono ndi durability mkulu chipangizo. Ubwino wina yaikulu SSD chipangizo n'zogwirizana ndi polumikizira zonse zodyerana.

wosuta wina, tipeze chimene SSD, ngati kuti chipangizo ndi pafupifupi palibe zolakwika. Komabe, siziri choncho. The sangathe waukulu SSD imatengedwa yochepa "alumali moyo." Komanso kung'anima galimoto, olimba boma galimoto ali ndi amalire chiwerengero cha m'zinthu lemba. Makamaka chilema ichi kwambiri anamva chifukwa cha kukwera mtengo kwa chipangizo, potsata buku ake.

Ambiri amachita chidwi osati zimene SSD, komanso ndi chipangizo wosiyana ndodo alipidwa zomwe. SSD tinganene kuti ndi "m'bale chachikulu" kung'anima. Akusiyana, poyamba pa zonse, mfundo kuti USB pagalimoto m'modzi yekha Chip kung'anima-pamtima, ndi SSD zingapo, ndipo mauthenga pa iwo kwalembedwa alternately. Nthawi zambiri, kuti awonjezere ntchito chipangizo pa ake PCB wokwera umodzi kung'anima kukumbukira Chip. Opha mu yosungirako olimba boma ndi zosavuta kuposa USB. Izi zimathandiza SSD yaitali kugwira ntchito.

Ndithu anthu ali nkhawa funso limeneli ndi momwe utumiki akuti SSD. Mofanana ndi USB galimoto, galimoto boma olimba, moyo alumali si kuyeza ndi zaka, ndi overwrite m'zinthu. pagalimoto yawo waima ku zikwi mazana asanu ndi hafu miliyoni. Choncho, m'pamene ntchito chipangizo, liwiro adzakhala opanda pake. Kumawonjezera moyo opaleshoni ndipo opha yosungirako wapadera umene maselo kukumbukira ntchito kwambiri kapena zochepa mofanana. Koma nthawi, kutsogolera opanga SSD zimatsimikizira zaka zitatu vuto lililonse ntchito mankhwala ake. Pamene kumapeto SSD "alumali moyo", izi sizikutanthauza kuti chipangizo wathyoka. Iwo sadzatha kulemba zinthu zatsopano, koma deta kusungidwa pa izo nthawizonse zidzakhala zilipo.

Pakati pa SSD ndi amasiyana makamaka kukula. Kawirikawiri mwina 1.8 inchi kapena 2.5 inchi, koma nthawi zina pamakhala sanali muyezo 3.5-inchi unit. Iwo imakhala kudzera eSATA cholumikizira. Pamene inu kugwirizana SSD kudzera USB-mawonekedwe ndi bwino kugwiritsa ntchito USB 3,0. Tsopano, pamodzi ndi abulusa boma okhazikika, SSD, pali makadi thambo amene ntchito mu Malaputopu ndi maseva. Komanso, opanga ambiri kubala ngati "hybrid" SSD ndi ochiritsira litayamba zovuta. Chotero zipangizo hybrid ndi liwilo ndi mipata yokwanira kusunga deta.

Ambiri Intaneti ndisanaphunzire kudalira abulusa olimba boma. Kupeza mayankho a mafunso okhudza zimene SSD, aliyense adzatha kusankha lifunika mtundu watsopano wa chipangizo yosungirako, kapena inu mukhoza kutenga zinthu zakale chosungira.
