Yintoni i-Solid-State Drive (SSD)?

Siyazi ukuba inkumbulo inokuba ziindidi ezimbini - eguqukayo kunye engagungqiyo . I-SSD sisixhobo sokugcina esingazinzanga. Oku kuthetha ukuba idatha egcinwe kwi-SSD ihlala nasemva kokumiswa kombane. Ngenxa yoyilo lwabo (zenziwe nge-flash controller kunye ne-NAND memory memory chips), ii-solid-state drives zikwabizwa ngokuba zii-flash drive okanye iidiski ezomeleleyo.

Ii-SSD-Imbali emfutshane

Iidiski zediski enzima bezisetyenziswa ikakhulu njengezixhobo zokugcina iminyaka emininzi. Abantu basasebenza kwizixhobo ezinediski enzima. Ke, yintoni eyatyhala abantu ukuba baphande ngesixhobo esinye sokugcina ngobuninzi? Ziye zabakho njani ii-SSD? Masithathe umbono omncinci kwimbali ukuze siyazi inkuthazo ebangelwa zii-SSD.

Kwiminyaka ye-1950s, bekukho itekhnoloji ye-2 esetyenziswayo ngokufana nendlela esebenza ngayo ii-SSD, ezizezi, imemori engundoqo yemagnethi kunye nekhadi lokufunda kuphela lekhadi. Nangona kunjalo, kungekudala ziye zaphela ekulibalekeni ngenxa yokufumaneka kweeyunithi zokugcina igubu ezingabizi kakhulu.

Iinkampani ezinje nge-IBM zisebenzise ii-SSD kwii-supercomputer zazo zokuqala. Nangona kunjalo, ii-SSD zazingasetyenziswa rhoqo kuba zazibiza. Emva kwexesha, ngoo-1970s, isixhobo esasibizwa ngokuba siMbane esinoMbane Igumbi yenziwe ziiGeneral Instruments. Nale, ayizange ihlale ixesha elide. Ngenxa yemicimbi yokuqina, esi sixhobo naso asifumananga kuthandwa.

Ngo-1978, i-SSD yokuqala yayisetyenziswa kwiinkampani zeoyile ukufumana idatha yenyikima. Kwi-1979, inkampani i-StorageTek iphuhlise i-RAM ye-RAM yokuqala.

i-RAM Ii-SSD ezisekwe ixesha elide bezisetyenziswa ixesha elide. Nangona bekhawuleza, batya izixhobo ezininzi ze-CPU kwaye babebiza kakhulu. Kwasekuqaleni kuka-1995, ii-SSD ezisekwe kwiflash zaphuhliswa. Ukusukela ekungenisweni kwe-SSD esekwe kwiflash, usetyenziso oluthile lweshishini olufuna okhethekileyo I-MTBF (ixesha elichazayo phakathi kokusilela) rate, ii-HDD zithathelwe indawo zii-SSD. Ukuqhuba kukarhulumente oqinileyo kuyakwazi ukumelana nokothuka okukhulu, ukungcangcazela, utshintsho lobushushu. Ngaloo ndlela banokuxhasa ngokufanelekileyo Amaxabiso eMTBF.

Zisebenza njani iiSolid State Drives?

Ii-SSDs zakhiwe ngokudibanisa ndawonye ii-memory chips kwi-grid. Iichips zenziwe nge-silicon. Inani leetshipsi kwisitaki litshintshiwe ukufezekisa uxinizelelo ezahlukeneyo. Emva koko, baxhotyiswa ngesantya sokudada emasangweni ukuze babambe imali. Ke ngoko, idatha egciniweyo igcinwa kwii-SSDs naxa zikhutshiwe kumthombo wamandla.

Nayiphi na i-SSD inokuba neyenye yeefayile ze- iintlobo ezintathu zememori - inqanaba elinye, amanqanaba amanqanaba amaninzi okanye iiseli zenqanaba lesithathu.

1. Iiseli zenqanaba elinye zezona zikhawulezayo nezomeleleyo kuzo zonke iiseli. Ke, zezona zibiza kakhulu. Ezi zenzelwe ukubamba idatha enye nangaliphi na ixesha.

2. Iiseli zamanqanaba amaninzi ingabamba ii-bits ezimbini zedatha. Kwisithuba esinikiweyo, banokubamba idatha ngakumbi kuneeseli zenqanaba elinye. Nangona kunjalo, banesiphene-isantya sabo sokubhala siyacotha.

3. Iiseli zamanqanaba amathathu Ezona zixabiso liphantsi liqashiso. Azomelele kancinci. Ezi seli zinokubamba idatha ezi-3 kwiseli enye. Babhala isantya sesona sicothayo.

Kutheni i-SSD isetyenziswa?

IiDisk eDisk eziHard ibe sisixhobo esigcinekayo sokugcina iinkqubo, ixesha elide. Ke, ukuba iinkampani zitshintshela kwii-SSDs, kukho isizathu esivakalayo. Makhe sibone ukuba kutheni ezinye iinkampani zikhetha ii-SSDs kwiimveliso zazo.

Kwi-HDD yesiko, uneemoto ukujikeleza isitya, kunye nentloko ye-R / W ihamba. Kwi-SSD, ukugcinwa kuthathwa ngononophelo lweememori zeetshiphu. Ke, akukho zixhobo zihambayo. Oku kwandisa ukuhlala kwesixhobo.

Kwiilaptops ezinedrive drive, isixhobo esigciniweyo siya kudla amandla amaninzi okujikeleza isitya. Kuba ii-SSDs azinazo iindawo ezihambayo, iilaptops ezinee-SSD zisebenzisa amandla amancinci. Ngelixa iinkampani zisebenzela ukwakha ii-HDD zeHybrid ezisebenzisa amandla amancinci ngelixa zijikeleza, ezi zixhobo ze-hybrid ziya kudla amandla amaninzi kune-solid-state drive.

Ewe, kujongeka ngathi akunazo naziphi na izinto ezihambayo eziza nezibonelelo ezininzi. Kwakhona, ukungabinayo into yokusonta okanye ukuhambisa iintloko ze-R / W kuthetha ukuba idatha inokufundwa kwi-drive phantse kwangoko. Ngee-SSD, i-latency iyancipha ngokubonakalayo. Ke, iinkqubo ezinee-SSD zinokusebenza ngokukhawuleza.
