Cov tsav tsheb ua lag luam yuav tsum tau tu ntau dua
Chang-Gyu Hwang, tus thawj coj ntawm Samsung Semiconductor, ib zaug kwv yees tias lub peev xwm ntawm flash nco chips yuav ob npaug txhua txhua xyoo. Tsab cai no tau tsim muaj tsib xyoos. Lub peev xwm ntawm 32 Gigabit chips uas tawm los ntawm qhov kawg ntawm 2006 yog ob zaug ntawm 2005 thiab 64 lub sij hawm ntawm xyoo 2000. Raws li Hwang txoj cai, cov neeg tsav tsheb disk yuav tsum zoo dua txog cov teeb meem kev tswj kev tswj kev ua kom tsis muaj teeb meem.
Kev sib tw sib txeeb hauv kev lag luam yuam kev tsav cov lag luam kom siv ntau txoj kev tswj kom muaj kabmob. Dluab muaj nyob rau ntawm Hitachi GlobalStorage Technologies.
Joseph Unsworth, tus thawj xibfwb tseem ceeb ntawm Gartner Dataquest Semiconductor, said txoj kev sib tw yuav tau txuas mus txog thaum 2010, thaum tus nqi ntawm lub cim nco flash poob ntau tshaj 50% toj ib xyoo. Unsworth taw tes tias qhov kev cia siab no nthuav tawm rau cov neeg tsav tsheb. Nws hais tias: "Raws li tus nqi tseem pheej poob thiab muaj peev xwm tseem nce, ces koj yuav tsum teev hom ntawv tshiab, xws li nyuaj drives."
Hard disk manufacturers tuam txhab muaj kev tswj xyuas ntau dua kev tswj, feem ntau vim yog qhov zoo li no, tiam sis lub ntsiab qhov siab yog los ntawm kev sib tw hauv kev lag luam. Raws li ClintDyer, tus lwm thawj coj ntawm Hitachi Global Storage Technologies hauv San Jose, Calif., Qhov kev ntsuas loj tshaj plaws, qhov nyiaj ntawm cov ntaub ntawv khaws cia hauv qhov chaw disk, thiab yuav ua li cas nce nws cov nqi yog qhov tseem ceeb tshaj. Nws hais tias: "Peb yuav tsum ua kom muaj qhov sib txawv ntawm qhov khoom, uas yuav tsum tau tu ntau dua ntawm kev huv."
Rau lub hard disk, qhov tseem ceeb yog qhov kev ncua deb ntawm lub taub hau thiab cov chassis rotating, thiab qhov sib txawv ntawm cov hlau nplaum hauv lub chassis. Lawv tsuas yog ob peb tus neeg nanometers. Kev tswj hwm huab cua muaj xws li kev siv hoob 10 (ISO Class 4) huv chav hauv cov chaw tseem ceeb tshaj plaws, kev siv cov khoom ua tib zoo xaiv, kev sib txuas ntawm cov cuab yeej thiab lwm yam kev ntsuas.
Hardy maker Seagate Technology spokesperson ForrestMonroy tau hais tias Seagate muaj ib hoob 100 (ISO Class 5) huv chav hauv Singapore uas tuaj yeem kho tau ntxiv rau chav kawm ISO 4 chav huv. Seagate muaj cuaj chav nyob hauv qhov chaw, txhua qhov yuav tsum muaj 150 x 100 square feet. Cov kev siv zog txo qis qis qis xws li tswj kev tswj hluav taws xob, tswj kev kawm thiab kev ua haujlwm ntawm cov neeg ua haujlwm.
John Monroe, tus thawj tswj hwm ntawm kev tshawb fawb thiab kev loj hlob ntawm Gartner, tau hais tias cov kev tswj kev ua kom tsis zoo no ua rau muaj kev ceev thiab cov khoom tawm tuaj. Txawm li cas los xij, qhov no los ntawm ib tus nqi vim tias tus tsav nyuab yog ib qho khoom siv hluav taws xob nrog outgassing thiab kev co, thiab qhov kev siv tshuab no yuav tsum kav ntev ntau xyoo. Monroe tau hais tias: "Txoj kev ua paug tuaj yeem ua rau magnetic field tsis ua hauj lwm, uas yog kev puas tsuaj."
Txuj kev tswj ntawm kev tshem tawm electrostatic, kev cob qhia cov neeg ua hauj lwm thiab kev siv cov tshuab automation tuaj yeem muaj ceev thiab cov khoom tawm los. Seagate Technology muab duab.
Dua li ntawm cov kev siv zog, cov neeg tsav tsheb ua lag luam muaj ntsej muag ib qho kev sib tw ua rau flash memory nco nyob hauv qee yam khoom. Tus nqi tsim ntawm tus tsav nyuaj yog tsau thiab tam sim no nyob ib ncig ntawm $ 40. Rau cov uas tsis muaj qis, cov nqi ntawm flash nco yuav qis dua qhov pheej yig nyuaj tsav. Txawm li cas los xij, zoo dua kev tswj kuab paug tuaj yeem ua rau cov khoom tsim tawm thiab txo tus nqi ntawm cov tsav nyuaj.
Ntawm qhov kev sib tw, cov tsav tsheb tsis txaus ntseeg tau siv sijhawm ntawm Hwang txoj cai. Ib txhia tuam txhab tau tshaj tawm hybrid drives, ib tug tsav uas siv ob lub chassis thiab flash nco. Hom tsav no yog feem ntau lub sij hawm dormant, uas txuag lub zog thiab spins tsawg tshaj li ntawm ib feeb twg hauv kev siv. Hybrid nyuaj drives yuav tsum tsiv mus sai sai hauv ob peb xyoos tom ntej no.
