ʻO Michal Ždanský E like me ka mea i manaʻo ʻia, ua loaʻa i nā MacBook hou kahi awa Thunderbolt (LightPeak) kiʻekiʻe kiʻekiʻe, a ʻo nā kamepiula Apple ʻē aʻe e hahai. Ma kēia ʻatikala, makemake wau e nānā kikoʻī i ka Thunderbolt hanohano, mai kahi ʻenehana a me kahi manaʻo.
Hekili ma lalo o ke aniani hoʻonui
ʻOiai ua kamaʻilio nui ʻo LightPeak e pili ana i ka lawe ʻana i ka fiber optical, ʻo Thunderbolt, i ʻike ʻia ma ka MacBook Pro, he metallic, ʻo ia hoʻi ka hoʻoili ʻana ma luna o nā electrons, ʻaʻole nā photons. ʻO kēia ke ʻano hiki iā mākou ke moeʻuhane e pili ana i ka wikiwiki theoretical o 100 Gb / s no kēia manawa, a me nā kaula 100 m. Ma ka lima ʻē aʻe, mahalo i nā electrons, hiki i ka Thunderbolt ke hoʻopaʻa i nā mea passive a hiki i 10 W, a e emi loa ke kumukūʻai ma muli o ka nele o nā optics. Manaʻo wau e loaʻa i ka mana optical e hiki mai ana kahi ʻāpana metala no ka hoʻopiʻi wale ʻana.
Hoʻohana ʻo Thunderbolt i ka interface PCI Express 2.0 e kamaʻilio ai. Loaʻa iā ia ka throughput a hiki i 16 Gb/s. Hoʻohana nui ʻia ʻo PCI Express e nā kāleka kiʻi. No laila, lilo ʻo Thunderbolt i ʻano o waho PCI Express, a i ka wā e hiki mai ana hiki iā mākou ke manaʻo i nā kāleka kiʻi waho i hoʻopili ʻia ma o ka interface hou o Intel.
ʻO Thunderbolt, ma ka liʻiliʻi loa e like me ka mea i hōʻike ʻia e Apple, ua hui pū ʻia me ka mini DisplayPort i ka hoʻoponopono hou ʻana 1.1 a hiki ke hoʻohālikelike i hope me ia. No laila inā pili ʻoe, no ka laʻana, kahi Apple Cinema Display ma o Thunderbolt, e hana maʻamau ia, ʻoiai inā ʻaʻole i loaʻa i ka Apple monitor ka Thunderbolt.
ʻO ka mea hoihoi loa, ʻo ka interface hou he ʻelua-kanal a bidirectional. Hiki i nā kahawai ʻikepili ke holo like, e hopena i ka hoʻoili ʻana o ka ʻikepili a hiki i 40 Gb/s, akā me ka ʻoiaʻiʻo ʻo ka wikiwiki loa o hoʻokahi kahawai ma kahi ʻaoʻao he 10 Gb/s. No laila he aha ka maikaʻi? No ka laʻana, hiki iā ʻoe ke hoʻololi i ka ʻikepili ma waena o nā mea ʻelua i ka manawa like me ka wikiwiki kiʻekiʻe loa i ka hoʻouna ʻana i ke kiʻi i kahi nānā waho.
Eia kekahi, hiki i ka Thunderbolt ke kapa ʻia ʻo "daisy chaining", ʻo ia ke ʻano o nā mea kaulahao. Ma kēia ala, hiki iā ʻoe ke hoʻohui pū i nā polokalamu 6 me kahi awa Thunderbolt e hana ma ke ʻano he mau mea hoʻokomo / puka a hiki i nā mea nānā 2 me DisplayPort ma ka hope o ke kaulahao (me nā mākaʻi ʻelua he mau mea 5), e hana ana. ʻaʻole pono ka Thunderbolt. Eia kekahi, he liʻiliʻi liʻiliʻi ʻo Thunderbolt (8 nanoseconds) a me kahi hoʻololi hoʻololi pololei loa, he mea nui ʻaʻole wale no ka daisy chaining.
USB 3.0 pepehi kanaka?
Hoʻoweliweli ka Thunderbolt i ka USB 3.0, ke ulu mālie nei. Hāʻawi ka USB hou i ka wikiwiki hoʻololi a hiki i 5 Gb/s, ʻo ia hoʻi ka hapalua o ka hiki o Thunderbolt. Akā ʻo ka mea a USB ʻaʻole i hāʻawi ʻia nā mea e like me ke kamaʻilio multi-channel, daisy chaining, a ʻaʻole wau i manaʻo e hoʻohana ʻia no ka hoʻopuka composite A/V. ʻO USB 3.0 ka mea ʻoi aku ka wikiwiki o ke kaikunāne ʻelua o mua.
Hiki ke hoʻopili ʻia ʻo USB 3.0 i ka motherboard ma o PCI-e, akā naʻe, ʻaʻole ʻae ʻo Thunderbolt i kēia. Pono e hoʻokō pololei ʻia ma ka motherboard, no laila inā ʻoe e noʻonoʻo nei e hoʻohui i ka Thunderbolt i kāu PC, pono wau e hōʻino iā ʻoe. Eia nō naʻe, hiki iā mākou ke manaʻo iā Intel a me nā mea hana motherboard ʻē aʻe e hoʻomaka e hoʻokō i nā huahana hou.
ʻO ka mea kānalua, he mea hoʻokūkū pololei ʻo Thunderbolt o ka USB hou, a aia ke kaua ikaika ma waena o lākou. Ua hakakā ʻo USB i kahi kaua like me ka interface FireWire hou. A hiki i kēia lā, ua lilo ʻo FireWire i mea liʻiliʻi, ʻoiai ua kokoke ʻo USB ma nā wahi āpau. ʻOiai ua hāʻawi aku ʻo Firewire i kahi uku hoʻoili kiʻekiʻe, ua hoʻopilikia ʻia e ka laikini uku, ʻoiai ua manuahi ka laikini USB (koe wale no ka mana USB kiʻekiʻe kiʻekiʻe kūikawā). Eia naʻe, ua aʻo ʻo Thunderbolt mai kēia kuhi hewa a ʻaʻole koi i nā uku laikini mai nā mea hana ʻaoʻao ʻekolu.
No laila, inā lanakila ʻo Thunderbolt i kona wahi i ka lā, ʻo ka nīnau inā pono ʻo USB 3.0. Hiki ke hoʻohālikelike ʻia me USB me Thunderbolt ma o ka hōʻemi ʻana, a lawa ka USB 2.0 o kēia manawa no ka hoʻoili ʻana i nā ʻikepili maʻamau o nā flash drive. No laila e paʻakikī ana ka USB hou, a i loko o kekahi mau makahiki e hoʻopau loa ʻo Thunderbolt iā ia. Eia kekahi, 2 mau mea pāʻani ikaika loa e kū ma hope o Thunderbolt - Intel a me Apple.
He aha ka maikaʻi?
Inā hiki iā mākou ke kamaʻilio e pili ana i kēia manawa, a laila ʻaʻole hoʻohana ʻia ʻo Thunderbolt i ka hoʻomaʻamaʻa, ma muli o ka loaʻa ʻole o nā polokalamu me kēia interface. ʻAʻole ia he mea kupanaha, ʻo Apple ka mea mua i hōʻike kūʻokoʻa i ka Thunderbolt i loko o kāna mau puke puke, ʻoi aku, ua hōʻoia ʻia ka exclusivity no nā mahina he nui, ma ka liʻiliʻi ma ke ʻano o ka hoʻohui ʻana i nā motherboards.
Eia nō naʻe, ke hoʻomaka nei nā mea hana ʻē aʻe e lele me Thunderbolt. ʻO Western Digital, 'O ka ho'ohiki a LaCie ua hoʻolaha mua i ka hana ʻana o ka mālama ʻikepili a me nā mea hana ʻē aʻe me ka interface Intel hou, a hiki ke manaʻo ʻia nā mea pāʻani ikaika ʻē aʻe e like me Seagate, Samsung, A-ʻIkepili a ʻo nā mea hou aʻe e hoʻohui koke ʻia, no ka mea he kakaikahi ka poʻe e makemake e poina i ka nalu hou e hiki ai iā lākou ke holo ma ke kaulana. Ua lilo ʻo Apple i ʻano hōʻailona o ka ʻoiaʻiʻo e pili ana i ka hoʻokō ʻana i nā ʻenehana hou, a ʻo ka hapa nui o nā ʻenehana i kau ʻia ua lilo i mea nui i kekahi manawa, alakaʻi ʻia e ka USB kumu.
Hiki iā mākou ke manaʻo e makemake ʻo Apple e hoʻokō i ka Thunderbolt i ka hapa nui o kāna mau huahana. ʻO kahi hoʻoponopono hou o ka Time Capsule ua aneane 100% maopopo, e like me nā iMacs hou a me nā kamepiula Apple ʻē aʻe e hoʻolauna ʻia i ka wā e hiki mai ana. Hiki ke manaʻo ʻia ka hoʻolālā ʻana no nā polokalamu iOS, kahi e hoʻololi ai ʻo Thunderbolt i ka mea hoʻohui dock i kēia manawa. ʻAʻole hiki ke ʻōlelo ʻia i kēia makahiki, akā e kau wau i koʻu lima i ke ahi no ka mea ʻaʻole e pale hou ka iPad 3 a me iPhone 6.
Inā kūleʻa maoli ʻo Thunderbolt i ka haki ʻana i waena o nā polokalamu I/O, a laila hiki iā mākou ke manaʻo i kahi kahe o nā huahana me kēia interface ma ka hopena o ka makahiki. He mea maʻalahi loa ka Thunderbolt i hiki ke hoʻololi i nā mea hoʻohui hoʻoilina āpau a me nā pilina hou e like me HDMI, DVI a me DisplayPort me ka ʻole o ka maka. I ka hopena, ʻaʻohe kumu e hiki ʻole ai ke pani i kahi LAN maʻamau. ʻO nā mea a pau e hilinaʻi wale ana i ke kākoʻo o nā mea hana a me ko lākou hilinaʻi i ka interface hou a, ʻo ka mea hope loa, ma ka hilinaʻi o nā mea kūʻai aku.
Auwe. ʻAe, he ʻakaʻaka kēlā :)
ʻAʻohe mea ʻē aʻe e ʻōlelo ai no kēlā, ʻaʻole WOOOOW…!!! Ke kakali nui nei au i ka manawa e loaʻa ai iaʻu kahi mini-pidi Mabook Air kahi e hoʻohana nui ai i ka wā e hele ai a i koʻu hoʻi ʻana i ka home a hoʻohui iā ia i ka Cinema hou a loaʻa iā ia nā kiʻi ikaika a me kahi kani kani. hoʻokō ʻia i loko a ʻaʻole wau ʻike i nā mea ʻē aʻe a e lilo koke ia i mīkini ikaika no nā mea āpau. Maikaʻi kēlā, e ka haku. A i ʻole he papa a me ka hale kiʻiʻoniʻoni maikaʻi hoʻi :-)
