Niekedy v\u0161ak pri v\u00fdbere notebooku pr\u00eddete na to, \u017ee niektor\u00e9 z nich s\u00fa vybaven\u00e9 \u00falo\u017eiskom eMMC. To m\u00f4\u017ee by\u0165 trochu m\u00e4t\u00face, preto\u017ee disky eMMC s\u00fa ve\u013emi zriedkav\u00e9, najm\u00e4 v porovnan\u00ed s diskami SSD. V tomto pr\u00edpade v\u00e1s mo\u017eno zauj\u00edma, ak\u00fd je rozdiel medzi diskom eMMC a SSD a ktor\u00fd je pre rok 2022 relevantnej\u0161\u00ed.<\/p>\n\n\n\n
Ak chcete tieto dva typy \u00falo\u017e\u00edsk objekt\u00edvne porovna\u0165, mus\u00edte sa s nimi lep\u0161ie zozn\u00e1mi\u0165 a za\u010dnime s SSD.<\/p>\n\n\n\n
SSD je ve\u013ek\u00fd, zlo\u017eit\u00fd \u010dip, ktor\u00fd sa takmer cel\u00fd sklad\u00e1 z pam\u00e4\u0165ov\u00fdch buniek. SSD disk nem\u00e1 \u017eiadne pohybliv\u00e9 \u010dasti, \u010do znamen\u00e1, \u017ee nedoch\u00e1dza k \u017eiadnemu mechanick\u00e9mu opotrebovaniu.<\/p>\n\n\n\n
V porovnan\u00ed s tradi\u010dn\u00fdm pevn\u00fdm diskom je rozdiel v r\u00fdchlosti pomerne v\u00fdrazn\u00fd, preto\u017ee d\u00e1ta sa pres\u00favaj\u00fa r\u00fdchlej\u0161ie, preto\u017ee SSD nepotrebuje na svoju pr\u00e1cu ot\u00e1\u010da\u0165 magnetick\u00e9 disky a pohybova\u0165 magnetick\u00fdmi hlavami. V\u00e4\u010d\u0161ina diskov pre notebooky sa dod\u00e1va v 2,5-palcovom form\u00e1te SATA alebo M.2 a s\u00fa ve\u013emi ob\u013e\u00faben\u00e9 pri nov\u0161\u00edch modeloch notebookov.<\/p>\n\n\n\n
Ide o skratku pojmu Embedded Multimedia Memory Card (vstavan\u00e1 multimedi\u00e1lna pam\u00e4\u0165ov\u00e1 karta) a technicky sa tento detail takmer nel\u00ed\u0161i od be\u017en\u00e9ho flash disku Micro SD alebo samostatn\u00e9ho pam\u00e4\u0165ov\u00e9ho bloku polovodi\u010dov\u00e9ho disku.<\/p>\n\n\n\n
Tak\u00e9to disky sa \u010dasto pou\u017e\u00edvaj\u00fa v mobiln\u00fdch telef\u00f3noch a s\u00fa\u010dasn\u00fdch tabletoch, preto\u017ee maj\u00fa jednoduch\u00fa kon\u0161trukciu a s\u00fa ove\u013ea lacnej\u0161ie. Tak\u00e9to disky sa tie\u017e nevyzna\u010duj\u00fa ve\u013ek\u00fdm mno\u017estvom pam\u00e4te. Dnes najbe\u017enej\u0161ia “hmotnos\u0165” tak\u00e9hoto disku nepresahuje 128 GB. Na porovnanie, \u0161pi\u010dkov\u00e9 modely SSD diskov po\u010d\u00edtaj\u00fa s terabajtmi.<\/p>\n\n\n\n
Zvy\u010dajne je tak\u00fdto disk prip\u00e1jan\u00fd k z\u00e1kladnej doske notebooku alebo smartf\u00f3nu a sami ho ako SSD nebudete m\u00f4c\u0165 vymeni\u0165 a vymeni\u0165 ho m\u00f4\u017eu len odborn\u00edci v servisnom stredisku.<\/p>\n\n\n\n
Zjednodu\u0161ene povedan\u00e9, eMMC je nevyberate\u013en\u00e1 pam\u00e4\u0165ov\u00e1 karta, ktor\u00e1 je pripojen\u00e1 k doske plo\u0161n\u00fdch spojov.<\/p>\n\n\n\n
Ak vid\u00edte telef\u00f3n so 64 GB pam\u00e4te, ide o 64 GB pam\u00e4te eMMC. Podobne, ak si k\u00fapite tablet, ultrabook alebo netbook, je pravdepodobn\u00e9, \u017ee bude ma\u0165 namiesto jednotky SSD zabudovan\u00e9 \u00falo\u017eisko eMMC.<\/p>\n\n\n\n
E\u0161te pred piatimi rokmi sa len m\u00e1lokto zauj\u00edmal o porovn\u00e1vanie t\u00fdchto dvoch typov \u00falo\u017e\u00edsk, preto\u017ee SSD boli extr\u00e9mne drah\u00e9 a vo\u013eba eMMC bola pre v\u00e4\u010d\u0161inu ultrabookov alebo notebookov \u00faplne jasn\u00e1.<\/p>\n\n\n\n
V s\u00fa\u010dasnosti sa v\u0161ak cena SSD zn\u00ed\u017eila na cenovo dostupn\u00e9 \u00falo\u017eisko a kapacita \u00falo\u017eiska sa zn\u00e1sobila, tak\u017ee v\u00e4\u010d\u0161ina modern\u00fdch zariaden\u00ed pou\u017e\u00edva \u00falo\u017eisko eMMC. Jedinou v\u00fdnimkou s\u00fa smartf\u00f3ny, ktor\u00e9 st\u00e1le akt\u00edvne pou\u017e\u00edvaj\u00fa eMMC.<\/p>\n\n\n\n
Hlavn\u00fdm rozdielom medzi pam\u00e4\u0165ou eMMC a \u00falo\u017eiskom SSD je r\u00fdchlos\u0165 a cena. Disky SSD s\u00fa zvy\u010dajne ove\u013ea r\u00fdchlej\u0161ie ako disky eMMC, ale pam\u00e4\u0165 eMMC je ove\u013ea lacnej\u0161ia ako disky SSD podobnej ve\u013ekosti.<\/p>\n\n\n\n
Vysok\u00e1 r\u00fdchlos\u0165 diskov SSD vypl\u00fdva zo skuto\u010dnosti, \u017ee disk paralelne \u010d\u00edta a zapisuje \u00fadaje z viacer\u00fdch buniek pam\u00e4te flash (alebo do nich). eMMC m\u00f4\u017ee vykon\u00e1va\u0165 len sekven\u010dn\u00e9 \u010d\u00edtanie a z\u00e1pis, tak\u017ee neexistuje mechanizmus pre paraleln\u00e9 \u010d\u00edtanie z viacer\u00fdch buniek.<\/p>\n\n\n\n
Moduly eMMC dosahuj\u00fa v priemere r\u00fdchlos\u0165 sekven\u010dn\u00e9ho \u010d\u00edtania pribli\u017ene 100 MB\/s a r\u00fdchlos\u0165 z\u00e1pisu pribli\u017ene 40 MB\/s. Disky SSD pon\u00fakaj\u00fa ove\u013ea vy\u0161\u0161ie r\u00fdchlosti \u010d\u00edtania 400 MB\/s a z\u00e1pisu 150 MB\/s.<\/p>\n\n\n\n
Pam\u00e4\u0165 eMMC aj SSD pou\u017e\u00edvaj\u00fa na ukladanie \u00fadajov \u010dipy NAND. V\u00fdsledkom je, \u017ee pri pr\u00e1ci s eMMC aj SSD je postup \u010d\u00edtania ove\u013ea r\u00fdchlej\u0161\u00ed ako postup z\u00e1pisu \u00fadajov.<\/p>\n\n\n\n
Ka\u017ed\u00e1 bunka pam\u00e4te flash sa mus\u00ed vymaza\u0165, k\u00fdm sa do nej zap\u00ed\u0161u nov\u00e9 \u00fadaje. Rovnako ako v pr\u00edpade SSD je aj vymaz\u00e1vanie inform\u00e1ci\u00ed z buniek eMMC ove\u013ea pomal\u0161ie ako z\u00e1pis do pr\u00e1zdnej bunky.<\/p>\n\n\n\n
Nie je celkom f\u00e9r porovn\u00e1va\u0165 tieto dve pam\u00e4te, preto\u017ee sa pou\u017e\u00edvaj\u00fa v trochu odli\u0161n\u00fdch oblastiach. ako u\u017e bolo povedan\u00e9, eMMC sa pou\u017e\u00edva v telef\u00f3noch alebo tabletoch, zatia\u013e \u010do SSD sa pou\u017e\u00edva v po\u010d\u00edta\u010doch alebo notebookoch. Existuj\u00fa v\u0161ak krit\u00e9ri\u00e1, pod\u013ea ktor\u00fdch sa daj\u00fa porovna\u0165, a s\u00fa uveden\u00e9 v tabu\u013eke<\/p>\n\n\n\n Preto je SSD disk ove\u013ea r\u00fdchlej\u0161\u00ed ako eMMC, ale eMMC je ove\u013ea men\u0161\u00ed a lacnej\u0161\u00ed na v\u00fdrobu. Ak sa p\u00fdtate, \u010di si m\u00e1te k\u00fapi\u0165 elektroniku s eMMC, potom mus\u00edte vedie\u0165, \u017ee telef\u00f3ny alebo tablety s pam\u00e4\u0165ou eMMC s\u00fa dobr\u00e9, ale notebook je lep\u0161ie k\u00fapi\u0165 s SSD.<\/p>\n","protected":false},"excerpt":{"rendered":" \u013dudia \u010dasto po\u010duj\u00fa o SSD alebo HDD, preto\u017ee v\u00e4\u010d\u0161ina notebookov alebo PC ich m\u00e1.
