Momwe Baibulo Latsopano la SATA Lidzaonjezera PC Speeds
SATA kapena Serial ATA yakhala yopambana kwambiri pokhudzana ndi kusungirako makompyuta. Kugwiritsa ntchito mawonekedwe pa mawonekedwe kumathandiza kuti pakhale zovuta komanso zomangamanga pakati pa makompyuta ndi zipangizo zosungirako. Vuto ndilokuti mapangidwe a kuyankhulana kwaseri kwafika pamalire ake ndi machitidwe ambiri olimbitsa thupi omwe akugwedezeka ndi ntchito ya mawonekedwe m'malo moyendetsa galimoto. Chifukwa chaichi, njira zatsopano zolankhulirana pakati pa makompyuta ndi zosungirako zofunikira ziyenera kupangidwa. Apa ndi pamene SATA Express ikulowetsamo kudzaza phokoso la ntchito.
Kuyankhulana kwa SATA kapena PCI-Express
Zomwe zilipo SATA 3.0 zowonjezera zinali zokwanira 6.0Gbps bandwidth omwe amatanthawuza pafupifupi 750MB / s. Tsopano ndikumwamba kwa mawonekedwe ndi zonse, zikutanthauza kuti ntchito yodalirika inali yokwanira 600MB / s. Mibadwo yambiri yomwe ikuyendetsa bwino imakhala ikufika pamapeto pake ndipo imafuna mawonekedwe ofulumira. Mafotokozedwe a SATA 3.2 omwe SATA Expess ndi gawo la kukhazikitsa njira yatsopano yolankhulirana pakati pa makompyuta ndi zipangizo polola zipangizo kuti zisankhe ngati akufuna kugwiritsa ntchito njira yomwe ilipo kale, kutsimikizira kumbuyo kwa zipangizo zakale, kapena kugwiritsa ntchito PCI mwamsanga -Basi yopeza .
Basi la PCI-Express lakhala likugwiritsidwa ntchito poyankhulana pakati pa CPU ndi zipangizo zamakono monga makhadi ojambula, mapulogalamu ochezera mauthenga, ma phukusi a USB, ndi zina. Pansi pa miyezo yomwe ilipo PCI-Express 3.0, njira imodzi yokha ya PCI-Express ikhoza kugwiritsira ntchito 1GB / s kuzipanga mofulumira kuposa mawonekedwe a SATA omwe alipo. Izi ndizo njira imodzi ya PCI-Express yomwe ikhoza kukwaniritsa koma zipangizo zingagwiritse ntchito njira zambiri. Malinga ndi ndondomeko ya SATA Express, galimoto ndi mawonekedwe atsopano angagwiritse ntchito maulendo awiri a PCI-Express (nthawi zambiri amawonetsedwa ngati x2) kuti akhale ndi mawonekedwe a 2GB / s omwe angapange katatu katatu mofulumira.
Wowonjezera Watsopano SATA Express
Tsopano mawonekedwe atsopano amafunikanso chojambulira chatsopano. Zingawoneke mofananamo chifukwa chojambuliracho chimagwirizanitsa zolumikiza ziwiri za SATA ndi kachipangizo kakang'ono kakang'ono kachitatu kamene kali ndi mauthenga a PCI-Express. Zogwirizanitsa ziwiri za SATA zenizeni zogwira ntchito SATA 3.0. Izi zikutanthauza kuti chojambulira chimodzi cha SATA Express pamakompyuta chingathe kuthandiza mazenera awiri akale a SATA. Nkhani imabwera pamene mukufuna kutsegula galimoto yatsopano yotchedwa SATA Express mujambuliro. Onse ogwirizana a SATA Express adzagwiritsa ntchito chigawo chokwanira kaya galimotoyo ikuchokera pamauthenga akale a SATA kapena PCI-Express yatsopano. Kotero, imodzi SATA Express ingathe kuthana ndi magalimoto awiri a SATA kapena galimoto imodzi ya SATA Express.
Kotero bwanji osayendetsa galimoto ya SATA Express yochokera ku PCI-Express amangogwiritsa ntchito chojambulira chachitatu m'malo mwazitsulo ziwiri za SATA? Izi zikugwirizana ndi mfundo yakuti galimoto yoyendetsera SATA Express ingagwiritse ntchito zamakono, kotero iyenera kukhala ndi mawonekedwe onsewo. Kuphatikiza pa izi, madoko ambiri a SATA amathandizidwa ndi njira ya PCI-Express pokambirana ndi pulosesa. Pogwiritsa ntchito pulogalamu ya PCI-Express mwachindunji ndi galimoto ya SATA Express, mumathetsa kulankhulana kwazitsulo ziwiri za SATA zomwe zimagwirizanitsidwa ndi mawonekedwe awo.
Lonjezani malire a Zida
SATA ndi njira yolumikizira deta pakati pa chipangizo ndi CPU mu kompyuta. Kuphatikiza pa kusanjikiza, pali gawo losanjikiza lomwe limapitirira pamwamba pa izi kuti atumize malamulo pa zomwe ziyenera kulembedwa ndi kuziwerengera kuchokera ku galimoto yosungirako. Kwa zaka, izi zakhala zikugwiridwa ndi AHCI (Integrated Host Controller Interface). Izi zakhala zowonongeka kotero kuti zidalembedwa m'ntchito iliyonse yomwe ikugulitsidwa. Izi zimapangitsa kuti pulogalamu ya SATA ipange ndi kusewera. Palibe madalaivala apadera. Ngakhale kuti teknoloji inagwira ntchito bwino ndi luso lakale lopititsa patsogolo monga ma drive ovuta ndi ma drive a USB, imakhala ndi SSD mofulumira. Vuto ndiloti pamene mzerewu wa AHCI umatha kugwira malemba 32 pamzerewu, ukhoza kungogwiritsira ntchito lamulo limodzi pokhapokha pali mzere umodzi.
Apa ndi pamene lamulo la NVMe (Non-Volatile Memory Express) lilowa. Lili ndi mavoti asanu ndi asanu ndi asanu ndi limodzi (65,536) omwe angathe kugwira malemba 65,536 pamzere. Mwachangu, izi zimalola kufanana kwa yosungirako malamulo ku galimoto. Izi sizili zopindulitsa ku galimoto yochuluka ngati ikugwirabe ntchito imodzi yokha chifukwa cha mitu yoyendetsa galimoto koma kuti imayendetse bwino ndi mapulogalamu awo ambiri omwe amatha kukumbukira mapulogalamu awo amatha kupititsa patsogolo mapulogalamu awo amodzi mwa kulemba malamulo angapo kumapiko ndi maselo osiyana panthawi imodzi .
Izi zingawoneke bwino koma pali vuto lina. Izi ndi zamakono zamakono ndipo zotsatira zake sizinamangidwenso m'zinthu zambiri zomwe zilipo pamsika. Ndipotu, ambiri amafunika kukhala ndi madalaivala owonjezera kuti ma drive ayambe kugwiritsa ntchito luso lamakono la NVMe. Izi zikutanthauza kutumizidwa kwa ntchito yofulumira kwa ma drive a SATA Express kungatengere nthawi kuti pulogalamuyo ikhale yofanana ndi mawu oyamba a AHCI. Mwamwayi, SATA Express imapereka ma drive kuti agwiritse ntchito njira ziwirizi kuti mutha kugwiritsa ntchito makina atsopano tsopano ndi madalaivala AHCI ndipo mwinamwake mungasunthire kuzitsulo zatsopano za NVMe pambuyo pa ntchito yabwino, ngakhale mwina mukuyenera kuti galimotoyo ikonzedwe.
Zina Zina Zowonjezedwa ndi Express SATA kudzera pa SATA 3.2 Malingaliro
Tsopano zotsatila zatsopano za SATA zimaphatikizapo zowonjezera njira zatsopano zowankhulirana ndi chojambulira. Ambiri mwa iwo amawunikira makompyuta am'manja koma angathandizenso ma kompyuta ena osakhala nawo. Chinthu chodziwika kwambiri chopulumutsa mphamvu ndi njira yatsopano ya DevSleep. Izi ndizo mphamvu zatsopano zomwe zimalola kuti kusungirako kusatsekedwe kwathunthu kutseketsa mphamvu pamene mukugona. Izi ziyenera kuthandizira kusintha nthawi za laptops lapadera kuphatikizapo Ultrabooks zopangidwa kuzungulira SSD ndi kuchepa kwa mphamvu.
Ogwiritsira ntchito SSHD (olimba olimbitsa thupi) amathandizanso ndi miyezo yatsopano monga momwe adayikiramo zatsopano. Muzitsulo zamakono za SATA, woyendetsa galimoto angadziwe kuti ndi zinthu ziti zomwe siziyenera kutetezedwa ndi zomwe siziyenera kuchitika. Pogwiritsa ntchito mawonekedwe atsopanowu, machitidwewa angathe kumuuza woyendetsa galimotoyo zomwe ziyenera kugwiritsidwa ntchito pa cache zomwe zimachepetsa kuchulukitsa kwa woyendetsa galimoto ndikukweza ntchito.
Pomalizira, pali ntchito yogwiritsira ntchito ndi magalimoto oyendetsa galimoto. Imodzi mwa zolinga za RAID ndi data redundancy. Ngati galimoto ikulephera, galimotoyo ingasinthidwe ndiyeno deta idzamangidwanso kuchokera ku data ya checksum. Mwachidziwikire, amanga ndondomeko yatsopano mu miyezo ya SATA 3.2 yomwe ingathandize kusintha ntchito yomanganso polojekiti pozindikira kuti chiwonongeko chiwonongeke ndi chomwe sichiri.
Kukhazikitsa ndi Chifukwa Chake Sikunaphunzitsidwe
SATA Express wakhala chikhalidwe chovomerezeka kuyambira kumapeto kwa 2013 koma sanayambe kupanga njira zake mu makompyuta mpaka kutulutsidwa kwa chipsetse cha Intel H97 / Z97 kumayambiriro a chaka cha 2014. Ngakhale ndi mabotolo a makono tsopano omwe ali ndi mawonekedwe atsopano, alipo palibe makina oyendetsa panthawi yopititsa patsogolo omwe angathe kugwiritsa ntchito mawonekedwe atsopano. Izi zikutheka chifukwa cha zovuta zokhudzana ndi kayendedwe ka machitidwe opangira maulamuliro atsopano kuti agwiritse ntchito bwino SATA Express. Zomwe zingagwiritsidwe ntchito pakali pano zimalola kuti SATA Express zolumikizira zigwiritsidwe ntchito ndi ma SID omwe alipo. Izi ziyenera kuwathandiza kuthetsa kukhazikitsidwa kwa zomwe zikuchitika kugula teknoloji tsopano kamodzi komwe ma drive akupezeka.
Chifukwa chomwe mawonekedwewo sanagwiritsire ntchito mabodza ndi M.2 mawonekedwe. Izi zimagwiritsidwa ntchito pokhapokha poyendetsa kayendedwe kamene kamagwiritsa ntchito mawonekedwe ang'onoang'ono omwe amagwiritsidwa ntchito pa makompyuta apakompyuta komanso ndi ma kompyuta. Ma drive ovuta amakhalabe ovuta kupitirira miyezo ya SATA. M.2 imakhala yovuta kwambiri chifukwa sichidalira magalimoto aakulu koma ingagwiritse ntchito njira zinayi za PCI-Express zomwe zimatanthawuza mothamanga kwambiri kuposa njira ziwiri za SATA Express. Panthawiyi, ogula sangathe kuwona SATA Express ikuvomerezedwa.
