Txhua peb lub khoos phis tawj, loj thiab me, muaj cov tsav nyuaj ntawm qee hom thiab peb feem ntau paub tias nws yog cov khoom siv kho vajtse uas khaws peb cov software, suab paj nruag, yeeb yaj kiab, thiab txawm tias peb lub operating system.
Tshaj tawm qhov ntawd, txawm li cas los xij, tej zaum muaj tsawg kawg yog ob peb yam uas koj tsis tau paub txog cov khoom siv hauv computer:
Facts About Hard Drives
- Thawj lub hard drive, 350 Disk Storage Unit, tsis yog tsuas yog tshwm sim ntawm cov khw muag khoom ntawm qhov chaw tab sis yog ib feem ntawm lub khoos phis tawj ua tiav los ntawm IBM, tso tawm thaum lub Cuaj Hlis 1956… yog, 1956 !
- IBM pib xa cov cuab yeej tshiab no mus rau lwm lub tuam txhab hauv xyoo 1958, tab sis tej zaum lawv tsis yog tsuas yog lo rau hauv kev xa ntawv - lub ntiaj teb thawj lub zog tsav yog hais txog qhov loj ntawm lub tub yees thiab hnyav sab qaum teb ntawm ib tuj..
- Shipping yam ntawd yog zaum kawg ntawm tus neeg yuav khoom lub siab, txawm li cas los xij, xav txog qhov tseeb tias xyoo 1961 lub hard drive no tau xauj ntau dua $ 1,000 USD ib hlis. Yog tias qhov ntawd zoo li npau taws, koj tuaj yeem yuav ib txwm yuav nws rau me ntsis tshaj $ 34, 000 USD.
- Ib qho nruab nrab nyuaj tsav muaj hnub no, xws li 8 TB Seagate qauv uas yuav muag rau me ntsis tshaj $ 200 USD, yog tshaj 300 lab lub sij hawm pheej yig dua dua li thawj IBM tsav yog.
- Yog tus neeg siv khoom xyoo 1960 xav tau ntau qhov chaw cia, nws yuav raug nqi nws $77.2 billion USD, me ntsis ntau dua tag nrho GDP ntawm United Kingdom xyoo ntawd!
- IBM's kim, monstrosity ntawm lub hard drive muaj tag nrho lub peev xwm ntawm tsuas yog 4 MB, txog qhov loj ntawm ib qho, nruab nrab-zoo nkauj zoo li koj xav tau los ntawm iTunes lossis Amazon.
- Hnub no lub hard drives tuaj yeem khaws cia ntau dua li qhov ntawd. Raws li lig 2015, Nimbus tuav cov ntaub ntawv rau lub hard drive loj tshaj plaws, 100 TB ExaDrive, tab sis 8 TB drives muaj ntau dua (thiab tseem kim dua).
- Yog li tsuas yog 60 xyoo tom qab IBM's 3.75 MB hard drive yog qhov zoo tshaj plaws ntawm qhov zoo tshaj plaws, koj tuaj yeem tau tshaj 2 lab npaug ntau npaum li khaws cia hauv 8 TB tsav thiab, raws li peb nyuam qhuav pom, ntawm ib feem me me ntawm tus nqi.
- Cov hard drives loj dua tsis yog cia peb khaws cov khoom ntau dua li peb tau siv los ua tau, lawv ua kom tag nrho cov kev lag luam tshiab uas yooj yim tsis tuaj yeem muaj yog tias tsis muaj kev txhim kho loj hauv kev khaws cia technology.
- Nqis tab sis loj hard drives cia cov tuam txhab xws li Backblaze muab cov kev pabcuam uas koj thaub qab koj cov ntaub ntawv rau lawv cov servers tsis yog rau koj tus kheej thaub qab discs. Xyoo 2022, lawv tau siv 207, 478 hard drives los ua qhov ntawd, thiab xyoo 2020 cov hard drive tau khaws cia tag nrho ntawm 1 exabyte ntawm cov ntaub ntawv.
- Xav txog Netflix, uas, raws li tsab ntawv tshaj tawm xyoo 2013, xav tau 3.14 PB (uas yog ib puag ncig 3.3 lab GB) ntawm qhov chaw hard drive khaws tag nrho cov yeeb yaj kiab!
- Xav tias Netflix qhov kev xav tau loj? Facebook tau khaws cia ze li ntawm 300 PB ntawm cov ntaub ntawv ntawm lub hard drive hauv nruab nrab xyoo 2014. Tsis ntseeg, tus lej ntawd loj dua hnub no.
- Tsis tsuas yog muaj peev xwm khaws cia tau nce, tab sis qhov loj me kuj tau txo qis tib lub sijhawm… drastic li. Ib MB hnub no siv 11 billion lub sijhawm tsawg lub cev dua li MB tau ua thaum 50s lig.
- Saib lwm txoj hauv kev: tias 256 GB smartphone hauv koj lub hnab tshos sib npaug rau 54 pas dej da dej Olympictag nrho ntawm 1958-era hard drives.
- Nyob rau hauv ntau txoj kev, lub qub IBM hard drive tsis txawv ntawm cov hard drive niaj hnub no: ob qho tib si muaj p tom kawg uas tig thiab lub taub hau txuas rau ib sab caj npab uas nyeem thiab sau cov ntaub ntawv.
- Cov spinning platters yog zoo nkauj ceev, feem ntau tig 5, 400 los yog 7, 200 zaug ib feeb, nyob ntawm seb lub hard drive.
- Txhua qhov chaw txav mus ua kom sov thiab thaum kawg pib ua tsis tiav, feem ntau nrov nrov. Lub suab nrov uas koj lub khoos phis tawj ua yog tej zaum cov kiv cua ncig cua, tab sis lwm tus, cov tsis zoo, feem ntau yog lub sijhawm koj lub hard drive.
- Tej yam uas txav thaum kawg hnav tawm-peb paub qhov ntawd. Rau qhov ntawd, thiab qee qhov laj thawj, lub xeev lub zog tsav, uas tsis muaj qhov txav txav (nws yog ib qho loj heev flash drive), maj mam hloov cov tsoos hard drive. (Saib HDD vs SSD kom paub ntau ntxiv.)
- Hmoov tsis zoo, tsis yog ib txwm siv lossis SSD nyuaj tsav tuaj yeem txuas ntxiv mus tas li. Sim khaws ib daim ntawm cov ntaub ntawv nyob rau hauv ib qho chaw me me, thiab lub physics ntawm yuav ua li cas hard drives ua hauj lwm lov. (Qhov tseeb-nws hu ua superparamagnetism.)
- Txhua qhov txhais tau tias peb yuav tsum khaws cov ntaub ntawv sib txawv yav tom ntej. Ntau lub suab paj nruag sci-fi yog nyob rau hauv txoj kev loj hlob tam sim no, xws li 3D cia, holographic cia, DNA cia, pob zeb diamond cia, thiab ntau dua.
- Hais txog kev tshawb fawb tsis tseeb, Cov ntaub ntawv, cov cim hauv Android hauv Star Trek, hais hauv ib ntu uas nws lub hlwb tuav 88 PB. Qhov ntawd tsawg dua Facebook, zoo li, uas peb tsis paub meej tias yuav ua li cas.
