Pofika m'chaka cha 1987, kusintha kwa kuwala kunakhala chenicheni. Zinapangitsa kuti kampaniyo ikhale yopambana mpikisano wake wapamtima, Winchester, kakhumi (adalemba ngakhale ndi likulu "W"). Optimem ndi Verbatim omwe anali opanga panthawiyo anali akukonzekera ma prototypes a ma drive opangidwanso, pomwe akatswiri ndi akatswiri anali kupanga mapulani anthawi yayitali. Sayansi Yodziwika, imodzi mwa mizati yapadziko lonse ya sayansi yodziwika bwino ndipo ikupitabe mwamphamvu masiku ano, inapereka mwayi wojambula maginito m'nkhani yake "Erasable Optical Disks." Nkhaniyi inamaliza ndi ulosi wa Pulofesa Bill Meiklejohn, yemwe kale anali wogwira ntchito ku General Electric yemwe anatha zaka 35 akuphunzira za magnetism. Amakhulupirira kuti zida zojambulira maginito zidatsala ndi zaka khumi kuti zikhale ndi moyo, palibenso.
Verbatim pakadali pano imapanga kuyatsa kwa LED ndi zida zosindikizira za 3D. Othirira ndemanga ambiri salinso ndi moyo. Pakadali pano, msika wa HDD ndi wathanzi, ndipo kufunikira kosungirako kukuswa mbiri. Kuchuluka kwa ma hard drive omwe adatumizidwa chaka chatha adapitilira ma exabytes 800, kuwirikiza katatu kuposa Notre Dame de Paris yotchuka.
Ndipo komabe, maginito disks akutha. Iwo akuzimiririka, kutenga deta onse kunyumba. Osasiya zithunzi za m'mphepete mwa nyanja kapena laibulale yankhani zopeka za sayansi. Kumene akupita sikudziwika. Iwo adzakhala kwinakwake pamwamba pa mapiri, osati m'dera lathu. M'mitambo, kunena molondola.
Ogulitsa sakufunikanso kugulitsa ma HDD kumsika wa ogula. Ngakhale Western Digital, m'malo mwa chizindikiro chake WD Gold, tsopano akugulitsa zomwe nthawi zonse zimanyamula pansi pa chizindikiro cha Ultrastar-chodalirika, chapamwamba kwambiri. Chida cha seva.
Mwa njira, ndichifukwa cha kulowetsedwa kwa magazi atsopano kuchokera ku HGST kuti gawo la seva la WD likuwonetsa mphamvu zake komanso mphamvu zake. Kupatula apo, amayi apanyumba tsopano amavala ma SSD. Komabe, onse a WD ndi Seagate adalephera momvetsa chisoni pakukula kwawo kolimba. Kenako anakasakasaka msika kuti akhalebe mmenemo. Seagate idatenga SandForce kukhala owongolera, pomwe Western idakolola pogula SunDisk.
Tsopano, mafunde akutsatsa akugwira ntchito ma SSD. Koma mitundu yosadziwa zakale, kugwiritsa ntchito chiwembu chamadzi (Seagate's Barracuda, ndipo ngakhale kale, WD's Pirahna), ingokhala taxidermy mu nyumba yosungiramo zinthu zakale zaukadaulo.
Nanga bwanji ma HDD? Kodi posachedwapa tidzayiwala za iwo, monga momwe tinayiwalira za tepi ya maginito? Palibe njira: tidapulumuka pazidziwitso za ma drive 100 a TB, ndipo tidzapulumukanso kujambula kwa shingled. Sitidzazifunanso kunyumba.
