Shanduro Yakazarurwa yeSATA Inowedzera PC Speeds
SATA kana Serial ATA yave iri kubudirira kukuru kana zvasvika pakuchengetedza kombiyuta. Iyo standadization pahutachiona inoita kuti nyore nyore kuiswa uye kuwirirana pakati pemakombiyuta uye zvigadziridzo zvekuchengetedza. Dambudziko nderokuti urongwa hwekukurukurirana serialized hwasvika pamiganhu yayo nevakawanda zvakasimba zvinotungamirirwa nehutori zvave zvakagadzirwa nehutano hwehutauri panzvimbo yekutya. Nemhaka yeizvi, maitiro matsva ekukurukurirana pakati pekombiyuta uye yekuchengetedza zvigadziro zvinoda kuiswa. Apa ndipo apo SATA Express inotanga kupinda kuti izere gaphi yebasa.
SATA kana PCI-Express Kukurukurirana
Izvo zviripo zveSATA 3.0 zvinotsanangurwa zvaive zvishoma kusvika pa 6.0Gbps bandwidth iyo inoshandura kusvika kusvika 750MB / s. Iye zvino nepamusoro pekushandiswa kwehutano uye zvose, zvinoreva kuti kubudirira kwekushanda kwaingova kungosvika 600MB / s chete. Zvizhinji zvechizvarwa chemazuva ano chakasimba chinotyaira chave chasvika pamuganhu uyu uye chinoda imwe nzira yekukurumidza kushandiswa. Iko SATA 3.2 tsanangudzo iyo SATA Expess inobatanidzwa nzira itsva yekukurukurirana pakati pekombiyuta nemagadziro kuburikidza nekubvumira zvigadziro kusarudza kana vachida kushandisa nzira iripo ye SATA, kuchengetedza kushamwaridzana kumashure nemashandi akare, kana kushandisa PCI yakakurumidza -Bhuku rinodhinda .
Bhasi rePCI-Express rave richishandiswa pakukurukurirana pakati peCUU nemakironga emipirwo akafanana nemakadhi emagetsi, mapuraneti ekubatanidza, USB ports, etc. Pasizvino PCI-Express 3.0 maitiro, rimwe chete PCI-Express rinokwanisa kubata kusvika 1GB / s kuchiita kuti iwedzere kudarika ikozvino SATA interface. Ndizvo izvo imwe PCI-Express nzira inogona kubudirira asi zvigadzirwa zvinogona kushandisa nzira dzakawanda. Maererano nehuwandu hweSATA Express, motokari ine inoshandiswa itsva ingashandisa nzira mbiri dzePCI-Express (dzinowanzodhindwa se x2) kuti dzive nechepamusoro-soro ye 2GB / s zvichiita kuti inenge katatu faster yeSATA yakapfuura ma 3.0.
The New SATA Express Connector
Ikozvino hutachiona hutsva hunodawo hutano hutsva. Inogona kutaridzika zvimwechetezvo nokuti chibatanidza zvechokwadi chinosunganidza mbiri mbiri dzeSATA nhepfenyuro pamwe nechetatu zviduku zvichishamwaridzana zvinosangana nePI-Express. Iyo miviri miviri yeSATA inonyatsoshanda SATA 3.0 ports. Izvi zvinoreva kuti imwe nhengo ye SATA Express pamakombiyuta inogona kutsigira mawere maviri eSATA akare. Nyaya inouya apo unoda kuvhara SATA Express yakatarwa motokari yakananga kupinda mu connector. Vose veSATA Express vanobatanidza vachanyatsoshandisa huwandu hwakazara pasinei nokuti motokari yacho inobva kunekutaura kwekare SATA kana kuti PCI-Express itsva. Saka, imwe SATA Express inogona kutora inenge mbiri dzeSATA kana imwe SATA Express drive.
Saka nei harisi PCI-Express inotungamira SATA Express drive inoshandisa imwe chete yechitatu connector panzvimbo yezvikepe zviviri zveSATA? Izvi zvine chokuita nechokwadi chokuti motokari yeSATA Express yakashandisa inogona kushandisa teknolojia, saka inofanirwa kuva nehutano nevose. Pamusoro peizvi, nzvimbo dzakawanda dzeSATA dzinosanganiswa nePII-Express nzira yekukurukura neprotori. Kana ukashandisa PCI-Express interace zvakananga neSATA Express motokari, iwe unobvisa zvakasimba kutaurirana kumatokari maviri eSATA akabatanidzwa kune iyo inoshandiswa chero ipi zvayo.
Raira Kukwaniswa Kwema Interface
SATA inobudirira nzira yekukurukurirana dhiyabhorosi pakati pechirongwa uye CPU mumakombiyuta. Mukuwedzera kune izvi zvakasara, kune mutemo wekuraira unofamba pamusoro peizvi kutumira mirairo pane izvo zvinofanira kunyorerwa nekuverenga kubva pakachengetedza gwara. Kwemakore, izvi zvakaitwa neAHCI (Advanced Host Controller Interface). Izvi zvakave zvakanyatsogadziriswa zvokuti zvinonyorwa zvakanyorerwa mune zvose zvinoshandiswa panguva ino pamusika. Izvi zvinobudirira kuita kuti SATA inotungamirira ipaki uye kutamba. Hapana vatyairi vakawanda vanodiwa. Nepo teknolojia yakashanda zvakanaka nechembera yekugadzirwa kwekombiki yakadai sekufambisa madhini uye USB flash drives, inonyatsokurumidza kudzoka SSDs. Dambudziko nderokuti kunyange ruzha rweAHCI ruchigona kuchengeta mirairo 32 mumugwagwa, rinogona kungoita mutemo mumwechete panguva imwe chete nokuti pane mutsara mumwe chete.
Iyi ndiyo iyo mirayiridzo yeNVMe (Non-Volatile Memory Express) inosvika. Inoshandisa mazana emitambo 65,536 mumwe nomumwe ane kodzero yekubata mirairo 65,536 pamutsara. Nokubudirira, izvi zvinobvumira kufanana kwekuchengetedzwa kwekuchengetedzwa kwekuchengetedza kumotokari. Izvi hazvibatsiri kumudhudhudhu wakaoma sezvo uchiri kunyatsogumira kune rimwe chete murairo nekuda kwemasvondo ekufambisa asi kuti hurumende hurumende inotenderera nevana vavo vakawanda memori chips inogona kukurisa zvakasimba bandwidth nekunyora mirairo yakawanda kumapapiro akasiyana nemasero panguva imwe chete .
Izvi zvinogona kuve zvakanaka asi pane zvishoma zvechinetso. Iyi ndiyo teknolojia itsva uye nekuda kweiyo haina kuvakwa mune dzakawanda zvezvirongwa zvekushandisa zviripo pamusika. Zvechokwadi, vazhinji vanozofanira kuva nevanodhairi vatsva vakaiswa mukati mavo kuitira kuti madhairiki ashandise shanduro itsva yeNVMe. Izvi zvinoreva kushandiswa kwekukurumidza kushanda kwekutya kweSATA Express kunogona kutora nguva apo software inofanira kukura yakafanana neyokutanga yeAHCI. Ndinofara, SATA Express inobvumira kuti inotenderera kushandisa imwe nzira mbiri kuitira kuti iwe unogona kushandisa shanduro itsva ikozvino nevatyairi veAHCI uye inogona kutamira kune itsva yeNVMe mitemo gare gare pakuvandudza kushanda, zvisinei zvichida kuti motokari ichinje kuchinjwa.
Zvimwe Zvimwe Zvikamu Zvakawedzerwa neSATA Express neSATA 3.2 Specs
Ikozvino zvitsva zvitsva zveSATA zvinowedzera zvinopfuura nzira itsva yekukurukurirana nekubatanidza. Vakawanda vavo vanotarirwa kumakombiyuta asiri ega asi vanogona kubatsirawo mamwe makombiyuta asiri efoniwo zvakare. Nyaya inonyanya kukosha yekuchengetedza sangano ndiyo itsva DevSleep mode. Izvi zvinowanzova simba idzva remamiriro ezvinhu rinobvumira hurongwa hwekuchengetedza kunenge hwavharwa zvachose saizvozvo kuderedza simba rinowira kana uri muhope. Izvi zvinofanira kubatsira kuvandudza nguva dzinoshandiswa pamapapotendi akadai kusanganisira Ultrabooks yakagadzirwa zvakapoteredza SSD uye kushandiswa kwesimba kwepasi.
Vashandi veSSHD (yakasimba yehurumende yakashambadza) inobatsirwawo nemitemo mitsva sezvavakaisa mune imwe sarudzo yekugadzirisa. Mune ikozvino SATA inoshandiswa, mutungamiri wekutyaira aizotarisa kuti zvinhu zvipi zvingafanirwa uye hazvifanirwe kuchengetedzwa kubva pane zvaanoona zvichiuya zvinokumbirwa. Nechigadziro chitsva, chirongwa chekushandisa chinogona kuudza mutungamiriri wekutya izvo zvinhu zvinofanira kunge zvakachengetwa mumudziyo unoita kuti uwedzere huwandu hwepamusoro pane mutungamiriri wekutya nekuvandudza kushanda.
Pakupedzisira, kune basa rekushandisa ne RAID motokari setups. Chimwe chezvinangwa zve RAID ndezvekuregererwa kwe data. Muchiitiko chekushayikwa kwekufambisa, motokari yacho inogona kuchinjwa uye ipapo data ichavakwazve kubva pane checksum data. Muchidimbu, vakagadzira nzira itsva muSATA 3.2 mitemo inogona kubatsira kuvandudza nzira yekuvaka zvakare kuburikidza nekuziva kuti kudarika kupi kwakaparadzwa kune izvo zvisingaiti.
Kutevedzera uye Nei Zvisina Kuitwa
SATA Express yakange iri yepamutemo yepamutemo kubva pakuguma kwe2013 asi haina kutanga kutora nzira dzayo mumakombiyuta masvomho kusvikira kusunungurwa kwe chipsetse zveIntel H97 / Z97 mumusi wegore ra2014. Kunyange nemabhobho emadzimai iye zvino ane inoratidziro itsva, pane hapana inotyaira panguva yekutanga iyo inokwanisa kushandisa shanduro itsva. Izvi zvingangodaro nekuda kwezvinhu zvakapoteredza kushandiswa kwehutachiona hwemutambo wekutsvaga murairo mutsva kushandisa zvakakwana SATA Express. Zvichida kushandiswa kwemazuva ano kunobvumira kuti SATA Express zvibatanidze zvishandiswe nemakambani anonzi SATA aripo. Izvi zvinofanira kubatsira kubvisa kushandiswa kune izvo zvinoitika kuti utenge teknolojia iyo ikozvino kana madhini ari kuwanikwa.
Chikonzero icho chinoratidziro chaicho chisina kunyatsobatwa nhema chaizvo neMedia interface. Izvi zvinoshandiswa chete nekuda kwehutano hwakasimba hunoshandisa zviduku zvomufaira chinoshandiswa mumakombiyuta emakombiyuta asiwo pamwe nekombiyuta maitiro. Mafambiro akaoma anoramba ane nguva yakaoma kudarika nheyo dzeSATA. M.2 ine zvishoma zvinogadziriswa nokuti haibatsiri pamatokari makuru asi inogonawo kushandisa nzira ina dzePI-Express dzinoreva zvinomhanya zvishoma kudarika nzira mbiri dzeSATA Express. Parizvino, vatengi vangave vasati vaone SATA Express yakambogamuchirwa.
