SSD ndi chidule ndipo imayimira galimoto yoyendetsa galimoto kapena disk-state disk.
SSD ndi galimoto yomwe imaloleza kusunga ndi kupeza deta, yofanana ndi RAM. Mosiyana ndi galimoto yamphamvu, SSD ilibe ziwalo zosuntha. Izi zimapangitsa kufikitsa kwachinsinsi mofulumira, ntchito ikukhala chete.

Popeza mitengoyo ndi yochepa, SSD ndi yoyenera ngati mapulogalamu apakompyuta ndi lapakompyuta.

Mbiri ya ma drive ovuta ndi SSD

Sayansi ya disk yovuta ndi yokalamba (malinga ndi mbiri ya kompyuta). Pali kudziwika zithunzi za wathuwu IBM RAMAC litayamba 350 ku 1956 kuti amagwiritsa 50 24 inchi lonse mapanelo kukhala wolemera 3,75 MB malo litayamba. Izi ndizo kukula kwa fayilo ya 128Kbps MP3 lero. IBM yadzipatula yokha ndi RAMAC 350 pokhapokha ngati ntchito ndi mafakitale amagwiritsa ntchito.
Kodi kupita patsogolo sikungakhale kosangalatsa? Dothi lolimba la PC la 5,25 inakhazikitsidwa zaka zoyambirira za 1980. Makina oyendetsa 3,5 ndi ma XMUMX inch ma drivebook anabwera patangopita nthawi pang'ono. The mawonekedwe mkati chingwe kasintha zaka kuchokera siriyo kuti IDE (tsopano zambiri amatchedwa ena ofanana Ata kapena PATA) pa SCSI kuti siriyo Ata (SATA). Koma ntchito ndi yofanana: mumagwirizanitsa galimoto yolimba ku bokosi la ma PC. The Today 2,5- ndi 2,5 inchi abulusa ntchito makamaka SATA polumikizira (osachepera pa ma PC kwambiri ndi Macs), ngakhale ena SSDs mkulu-liwiro ntchito mofulumira PCI mawonekedwe. Mphamvuzo zawonjezeka kuchokera ku megabytes angapo kupita ku ma terabytes angapo.

SSDs vs. HDD: Ndi kusiyana kotani?

Mpaka posachedwa, ogula PC sankadziwa kwenikweni mtundu wa kukumbukira komwe kuli pakompyuta kapena kompyuta. Ngati adagula laputulo lapamwamba, mwina anali ndi galimoto yoyendetsa (SSD) monga yoyendetsa galimoto. Maofesi ena kapena laputopu iliyonse imabwera ndi galimoto yovuta ya "HDD" choncho. Padakali pano, akhoza kukonza ma PC ambiri ndi SSD. Ngakhale kuphatikiza kwa HDD ndi SSD n'zotheka.

Koma kodi mungasankhe ndani?

Chikhalidwe cha HDD choyendetsa galimoto ndi sitolo yosasinthasintha deta. Izi ndizo, ngati mutatseka dongosolo, zambiri sizidzatayika, monga momwe ziliri, mwachitsanzo, ndi deta yosungidwa mu RAM. Dothi lovuta kwambiri ndi mbale yachitsulo yokhala ndi maginito yomwe imasunga deta yanu. Kaya nyimbo, masewera kapena mafilimu. Mutu wowerenga / kulemba mu disk hard access data pamene disks amasinthasintha.
Ntchito za disk chikhalidwe disk ndi ofanana ndi disk hard. Komabe, deta imasungidwa mmalo mwa kukumbukira, pazomwe zimagwirizanitsa kukumbukira. Zipangizozi zingathe kukhazikitsidwa mu bokosi la ma sebulo (monga pa makina aang'ono) kapena pa PCI Express.

SSD ili ndi mbiri yochepa kwambiri. Chikumbutso chamakono chamakono ndikulingalira kokwanira kwa lingaliro lomwelo. Choyamba choyendetsa timadziwa kuti SSD idayambira pa chivomezi kuchokera ku netbooks kumapeto kwa zaka za 2000. Mu 2007 ndi OLPC XO-1 ntchito 1GB SSD ndi Asus Eee PC mndandanda 700 ntchito 2GB SSD monga yosungirako chachikulu. SSD ikugunda pa mapulogalamu a PC otsika ndipo XO-1 imagulitsidwa kosatha ku bokosilo. Monga makanema ndi ma PC ena omwe amatha kutulutsa pakompyuta amakhala abwino komanso amphamvu kwambiri, mphamvu za SSD zakula mofulumira. M'dziko lamakono lino, mutha kusintha mosavuta XMUMX inchi hard drive ndi SSD.

Ubwino ndi kuipa
Ma SSD ndi ma HDD amayendetsa ntchito yomweyi: mumayambitsa machitidwe anu ndi kusunga mawonekedwe anu ndi maofesi anu. Komabe mumasiyana m'njira inayake.
Zimasiyana motani?

Price: Ma SSD ndi okwera mtengo kuposa HD disks disk mwa euro pa gigabyte. 1TB mkati 2,5 inch drive hard drive imawononga pakati pa 30EUR ndi 50EUR. Mosiyana ndi zimenezi, SDD yokhala ndi mphamvu yomweyo imatenga pafupifupi 300EUR. Izi zimagwirizana ndi 3 Cent pa gigabyte ya disk hard and 30 Cent pa gigabyte ya SSD. Pamene ma disks ovuta amagwiritsa ntchito teknoloji yakale, yowonjezereka, iwo adzakhalabe olimba posachedwapa.

liwiro: Apa SSD imawala. PC yosungira SSD imayambira pansi pa miniti, kawirikawiri pamphindi. Diski yochuluka imatenga nthawi kuti ikufulumize deta yoyendetsera. PC kapena Mac omwe ali ndi boti la SSD mofulumira, ayambitsa mapulogalamu mofulumira, ndipo amasamutsa mafayilo mofulumira. Kaya mumagwiritsa ntchito kompyuta yanu kuti muzisangalatsa, sukulu kapena mwaluso, liwiro lachangu lingakhale loyenera.

kugawikana: Chifukwa cha zojambula zawo zozungulira, disks zolimba zimagwira ntchito bwino kwambiri ndi mafayilo akuluakulu omwe amasungidwa pamabwalo osakaniza. Mwanjira iyi, mutu wotsogolera ukhoza kuyamba ndi kuyima muyendetsedwe yopitirira. Pamene ma disks ovuta ayamba kudzaza, mafayilo akulu akhoza kufalikira pa HDD disk, zomwe zimachititsa kuti liwiro liwonongeke pansi pa zomwe zimatchedwa kugawidwa. Chifukwa cha kuchepa kwa mutu wa kuwerenga, SSDs ikhoza kusunga dera paliponse, popanda kutaya nthawi. Motero, ma SSD ali mofulumira.

durability: SSD ilibe magawo osunthira, kotero ndizotheka kuti deta yanu siidatayika ndi chirema. Pamene makompyuta atsekedwa, ma disks ambiri "park" awo mitu yawo yowerenga / kulemba. Komabe, mitu yophunzira ili ndi nanomillimeters pang'ono. Izi nanomillimeters zili zokwanira kuwononga HDD

phokoso: Ngakhalenso galimoto yolimba kwambiri imapangitsa phokoso lochepa kugwiritsidwa ntchito pamene ilo likugwiritsidwa ntchito pamene galimotoyo ikuzungulira kapena mkono wowerenga ukuyenda mobwerezabwereza. Ma SSD amachititsa kuti asakhale ndi phokoso chifukwa sangakhale opanga.

Fazit: Ma drive ovuta a HDD akuwonekera kutsogolo pa mtengo, mphamvu ndi kupezeka. Ma SSD ndi okwera mtengo kwambiri, koma ogwira ntchito mofulumira komanso odalirika. Ngati mtengo ndi mphamvu sizilibe kanthu, SSD ndiyo yabwino kwambiri.
