Pc External Storage Interface Kubva paSATA Standards
USB uye FireWire zvose zvave zvichinyanya kukonzerwa nekuchengetedzwa kwekunze, asi kushanda kwavo kwakaenzaniswa nevanenge vachiita madhesikoni nguva dzose yakasara shure. Nekuvandudzwa kwemaitiro matsva eSerial ATA, imwe itsva yekuchengetedza mafomu, kunze kweSerial ATA, ikozvino inotanga kupinda mumusika. Ichi chinyorwa chichatarisa mukati mechibvumirano chitsva, kuti chinofananidzwa sei nemafomu akange aripo uye kuti zvinorevei maererano neshoko rekuchengetedza kunze.
USB uye FireWire
Usati watarisa kunze kweSerial ATA kana interface eSATA, zvinokosha kutarisa paIndaneti uye FireWire interfaces. Zvose izvi zvinopindirana zvakagadzirwa sepamusoro-speed serial interfaces pakati pemakombiyuta system nekunze kweperiipherals. USB inonyanya kushandiswa uye inoshandiswa nehuwandu hwakawanda hwemativi akasiyana-siyana akadai sekeyboards, pice, scanners uye printers apo FireWire inenge inoshandiswa chete seyekunze yekuchengetedza.
Kunyange zvazvo izvi zvinoshandiswa zvinoshandiswa kune chekuchengetedza kunze, mabheji chaiwo anoshandiswa mune aya majaira achiri kushandisa SATA interface . Zvinorevei izvi ndezvekunze kwekunze kunogadzirisa dare rakaoma kana kuti optical rine bhiriji inoshandura zviratidzo kubva ku USB kana FireWire interface mukati meSATA interface inoshandiswa nekutya. Iyi shanduro inokonzera kusvibiswa mune zvakakwana zvekufambisa.
Chimwe chezvakakosha zvikuru izvo zvose izvi zvinopindirana zvakashandiswa ndihwo huni hunopisa hunopisa. Zvizvarwa zvakapfuura zvekuchengetedza interfaces kazhinji hazvina kutsigira kukwanisa kwekutyaira zvinowedzera kana kuti kubviswa kubva pane imwe nzira. Ichi chinyorwa choga ndicho chakaita kuti kunze kwemashamba ekuchengetedza zvipararire.
Chimwe chinhu chinonakidza chinogona kuwanikwa neSATA ndicho chikwata chokuwedzera. Izvi zvinobvumira sachigaro imwechete yeSATA kuti ishandiswe kubatanidza chekunze cheSATA chassis chinopa mafambisi akawanda mune imwe mhando. Izvi zvinogona kugovera kuchengetedzwa kwakakura mune imwe chisiki uye kukwanisa kukudziridza kuchengetedza kwakakura kuburikidza neRAID array .
eSATA vs. SATA
External Serial ATA inongova subset yezvimwe zvinotsanangurwa zveSerial ATA interface yakafanana. Iyo haisi basa rinodiwa, asi kuwedzerwa kunogona kuwedzerwa kune zvose mutungamiriri nemagetsi. Kuti eSATA iite zvakanaka zvose inofanira kusimbisa zvinhu zvakakodzera SATA. Izvi zvinonyanya kukosha sezvo vazhinji vedzinza rekutanga SATA vatongi uye zvinotya hazvitsigire Hot Plug simba iro rinokosha nokuda kwebasa rekunze kwekunze.
Kunyange zvazvo eSATA iri chikamu chezvinyorwa zvinoshandiswa neSATA, inoshandisa zvakanyatsosiyana zvakagadzirwa kubva mukati reSATA ma connector. Chikonzero cheizvi ndechekudzivirira zviri nani mitsara yakashata-yakashandiswa kushandura zviratidzo kubva kuEIM kuchengetedzwa. Inopawo 2m yakawanda kabhadhi yakaenzana yakaenzana ne1m yekambo dzomukati. Somugumisiro, iyo mhando mbiri dzedambo haigoni kushandiswa zvakasiyana.
Speed Kusiyana
Chimwe chezvinhu zvinokosha izvo eSATA inopa pamusoro pe USB uye FireWire inokurumidza. Kunyange zvazvo mamwe maviri ari kumusoro kubva pakushandura chiratidzo pakati pekunze kwekunze kwekwenyasi uye mukati mokufambisa, SATA haina dambudziko iri. Nokuti SATA ndiyo inoshandiswa inoshandiswa pane dzakawanda zvitsva zvinotyisa, shanduko isina kuchena pakati pekunze neyekunze inogumira inodiwa muimba. Izvi zvinoreva kuti kunze kwekushandisa kunofanira kumhanya nenzira imwe chete seyayo yeSATA motokari.
Saka, heunoi mhedziso yezvikamu zvakasiyana-siyana:
- USB 1.1 - 15 Mbps
- MotoWire (1394a) - 400 Mbps
- USB 2.0 - 480 Mbps
- MotoWire 800 (1394b) - 800 Mbps
- SATA 1.5 - 1.5 Gbps
- SATA 3.0 - 3.0 Gbps
- USB 3.0 - 4.8 Gbps
- USB 3.1 - 10Gbps
Inofanira kuonekwa kuti itsva ye USB midziyo yakabva ikozvino nokukurumidza munyanzvi kupfuura sarai yeSATA iyo inotungirirwa mukati mekuvhara kunze kwekushandisa. Chinhu ichi ndechekuti nekuda kwepamusoro pekushandura zviratidzo, USB itsva icharamba ichinonoka zvishoma asi kune vese vashandi, pane mhedzisiro. Nokuda kweizvi, zvikwata zveSATA zvisinganyanyozivikanwi iye zvino sezvo kushandisa USB-based enclosures zviri nyore zvikuru.
Mhedziso
Kunze kweSATA yaiva pfungwa huru apo yakatanga kubuda. Dambudziko nderokuti satiriyo yeSATA haina kunyanya kushandurwa mumakore akawanda. Somugumisiro, iyo interfaces yekunze yakave yakakurumidza zvikuru kupfuura yekuchengetedza zvinhu. Izvi zvinoreva kuti eSATA haina kunyanya kufanana uye chaizvoizvo haisi kushandiswa chaizvo pamakombiyuta akawanda zvachose. Izvi zvinogona kuchinja kana SATA Express inobata asi izvi hazvirevi kuti iyo USB inenge iine iyo yakanyanya kunze yekuchengetedzwa kwekuchengetedzwa kwemakore akawanda.
