PCIe flash card
Flash card yog ib lub cim xeeb uas siv cov cuab yeej siv flash nco los khaws cov ntaub ntawv hluav taws xob. Nws feem ntau yog siv los ua qhov nruab nrab ntawm cov khoom siv me me xws li cov koob yees duab digital, PDAs, MP3, thiab lwm yam, yog li nws zoo li me me, zoo li daim npav, yog li nws yog hu ua flash card PCI Express yog lub tsheb npav tshiab thiab cov qauv interface. Nws thawj lub npe yog "3gio". PCIe belongs rau high-speed serial point-to-point dual channel siab bandwidth kis tau tus mob. Cov khoom siv txuas nrog tau muab faib nrog cov channel bandwidth tshwj xeeb thiab tsis sib faib cov peev txheej. Nws tsuas yog txhawb nqa kev tswj hwm lub zog, kev qhia yuam kev, kev xa mus rau qhov kawg-rau-kawg, [7] kub ntsaws thiab kev pabcuam zoo (QoS) thiab lwm yam haujlwm muaj.
Lub hauv paus ntsiab lus yog ua raws li NAND flash nco. Lub cim xeeb tseem ceeb ntawm lub cim xeeb thiab NOR flash nco yog me ntsis. Cov neeg siv tuaj yeem nkag mus rau cov ntaub ntawv me ntsis ntawm random. Qhov chaw khaws cia yooj yim ntawm NAND flash nco yog nplooj ntawv (koj tuaj yeem pom tias nplooj ntawv ntawm NAND flash nco zoo ib yam li cov haujlwm ntawm hard disk, thiab ib qho ntawm hard disk yog 512 bytes). Lub peev xwm ua tau zoo ntawm txhua nplooj ntawv yog ntau yam ntawm 512 bytes. Lub peev xwm ua tau zoo yog hais txog qhov siv rau cov ntaub ntawv khaws cia, qhov tseeb, 16 bytes ntawm cov ntaub ntawv pov thawj yuav tsum tau ntxiv, yog li peb tuaj yeem pom cov lus qhia ntawm "(512 + 16) byte" hauv cov ntaub ntawv ntawm flash nco manufacturers. Feem coob ntawm NAND flash nco nrog lub peev xwm qis dua 2GB yog (512 + 16) bytes ntawm nplooj ntawv muaj peev xwm, thaum NAND flash nco nrog lub peev xwm siab dua 2GB nthuav dav nplooj ntawv muaj peev xwm mus rau (2048 + 64) bytes.
Tom qab pci-sig (PCI lub koom haum tshwj xeeb txaus siab) muab ntawv pov thawj thiab tso tawm, PCIe tau hloov npe "PCI Express" lossis "PCI-E" luv luv. Tus qauv tshiab no yuav hloov PCI thiab AGP tam sim no, thiab thaum kawg paub txog kev sib koom ua ke ntawm tus qauv tsheb npav. Nws yog tsuas yog siv nyob rau hauv SSD (khoom-xeev tsav) ntawm servers. Muaj ntau tus neeg xa khoom ntawm PCIe flash cards, xws li ibm-tms, Intel, LSI, OCZ, Samsung (hauv txoj kev npaj), SanDisk, STEC, SuperTalent thiab Toshiba (hauv txoj kev npaj). Cov khoom tsim los ntawm LSI yog qhov zoo tshaj plaws, nrog rau qhov zoo tshaj plaws thiab kev ua haujlwm zoo. Tam sim no, qhov tseeb version yog PCI-E 3.0, thiab muaj PCI-E (piv txwv li version 1. 2. {21}} specification tau ua ib qho kev hloov kho loj hauv cov ntaub ntawv xa mus ceev, uas yog, los ntawm yav dhau los 2.5Gbps tsheb npav zaus ob npaug rau 5.0gbps, uas txhais tau hais tias yav dhau los PCI Express 2.0 x16 interface tuaj yeem ua ob npaug rau qhov zoo kawg nkaus 10Gb / s tsheb npav bandwidth (1GB / S=8gbps)
