Discs yob thiab yob

Thaum lub caij nplooj ntoos hlav xyoo 1987, qhov kev hloov kho qhov muag tau dhau los ua qhov tseeb. Laser technology tso cai rau nws ua tau zoo tshaj nws cov neeg sib tw ze tshaj plaws, Winchester, kaum npaug (qhov ntawd yog qhov lawv tau sau, nrog tsab ntawv loj). Tom qab ntawd brainiacs Optimem thiab Verbatim tau npaj cov qauv ntawm kev rov sau dua tshiab, thiab cov kws tshaj lij thiab cov kws tshuaj ntsuam tau ua cov phiaj xwm mus sij hawm ntev. Ib qho ntawm lub ntiaj teb tus ncej ntawm kev tshawb fawb, tseem muaj sia nyob niaj hnub no, Nrov Science nyob rau hauv tsab xov xwm "Erasable optical disks" tshuav tsis muaj caij nyoog rau cov ntaub ntawv sib nqus. Cov ntawv tshaj tawm tau xaus nrog kev kwv yees los ntawm xibfwb Bill Meiklejohn, los ntawm lub sijhawm ntawd twb yog ib tus neeg ua haujlwm General Electric uas tau siv sijhawm 35 xyoo kawm cov hlau nplaum. Hauv nws lub tswv yim, cov khoom siv sib nqus kaw tau muaj kaum xyoo nyob, tsis muaj ntxiv lawm.

Verbatim niaj hnub no tsom rau LED teeb pom kev zoo thiab 3D luam ntawv raw cov ntaub ntawv. Ntau tus neeg tawm tswv yim tsis nyob hauv cov npe ntawm cov neeg nyob. Thiab HDD kev lag luam muaj kev noj qab haus huv, thiab kev thov rau kev khaws cia yog rhuav cov ntaub ntawv. Tag nrho lub peev xwm ntawm cov khoom siv hlau nplaum xa mus rau xyoo tas los tau tshaj 800 exabytes, uas yog peb zaug ntau dua li lub npe nrov Notre Dame de Paris.

Thiab tseem magnetic disks yuav ploj mus. Lawv tawm thiab tshem tawm tag nrho cov ntaub ntawv ntawm lub tsev. Sparing tsis muaj duab los ntawm hiav txwv los yog lub tsev qiv ntawv ntawm science ntawv tseeb. Lawv mus qhov twg tsis paub. Lawv yuav nyob rau qhov chaw siab ntawm lub roob thiab tsis nyob hauv peb cheeb tsam. Nyob rau hauv cov huab, kom meej meej.

Cov khw muag khoom tsis tas yuav ua lag luam HDDs hauv cov neeg siv khoom lag luam. Txawm tias Western Digital, es tsis txhob ntawm cov khoom lag luam WD Kub, tam sim no muag yam uas ib txwm nyob hauv qab daim ntawv lo - Ultrastar, cov khoom lag luam txhim khu kev qha thiab zoo. Server ntaus ntawv.

Los ntawm txoj kev, nws yog ua tsaug rau cov ntshav tshiab los ntawm HGST tias WD server ntu qhia nws qhov tseem ceeb thiab enviable kev vam meej. Tom qab tag nrho, cov niam tsev tam sim no nqa SSDs. Txawm li cas los xij, kev txhim kho hauv lub xeev ruaj khov ntawm WD thiab Seagate tau ua tiav tiav. Tom qab ntawd kuv yuav tsum tau mus thiab hais lus ntawm lub khw kom nyob ntawd. Seagate coj SandForce controllers, Western sau tag nrho cov qoob loo los ntawm kev yuav SunDisk.

Tam sim no kev lag luam nthwv dej ua haujlwm rau SSDs. Tab sis lub npe tsis zoo ntawm yav dhau los, siv lub ntsiab lus tseem ceeb ntawm cov dej (Barracuda los ntawm Seagate, txawm tias ua ntej Pirahna los ntawm WD), tsuas yog cov tsiaj txhu hauv tsev khaws puav pheej ntawm kev hloov pauv.

Yuav ua li cas yog HDD? Peb puas yuav tsis nco qab txog lawv, ib yam li peb tsis nco qab txog daim kab xev nplaum? Txawm hais tias nws zoo li cas: peb tau dim ntawm kev tshaj tawm ntawm 100TB tsav, peb kuj tseem yuav muaj sia nyob ntawm cov ntaub ntawv kaw. Koj yuav tsis xav tau nws nyob hauv tsev lawm.
