He aha ka Solid-State Drive (SSD)?
Ua ʻike mākou he ʻelua ʻano ʻano hoʻomanaʻo - hikiwawe a me ka ʻole . ʻO kahi SSD kahi mea mālama mālama ʻole. ʻO ia ke ʻano o ka ʻikepili i mālama ʻia ma kahi SSD ma hope o ka pau ʻana o ka mana. Ma muli o kā lākou hoʻolālā ʻana (ua hana ʻia lākou me kahi mea hoʻoponopono uila a me nā pahu hoʻomanaʻo flash NAND), ua kapa ʻia nā drive solid-state he flash drive a i ʻole solid-state disks.
SSDs - He moʻolelo pōkole
Ua hoʻohana nui ʻia nā ʻōpala paʻa paʻa ma ke ʻano he mālama mālama no nā makahiki he nui. Ke hana mau nei ka poʻe ma nā polokalamu me kahi disk paʻa. No laila, he aha ka mea i koi ai i ka poʻe e noiʻi i kahi mea mālama nui ʻē aʻe? Pehea i hoʻomaka ai nā SSD? E nānā kākou i ka mōʻaukala e ʻike i ke kumu hoʻoikaika ma hope o SSD.
I ka makahiki 1950, aia he 2 mau ʻenehana i hoʻohana ʻia e like me ke ʻano o ka hana ʻana o SSD, ʻo ia hoʻi, ka hoʻomanaʻo magnetic core a me ka hale kūʻai heluhelu wale nō ka card-capacitor. Akā naʻe, ua nalowale koke lākou i ka poina ma muli o ka loaʻa ʻana o nā ʻāpana hoʻopaʻa pahu maʻalahi.
Ua hoʻohana nā ʻoihana e like me IBM i nā SSD i kā lākou supercomputers mua. Akā naʻe, ʻaʻole i hoʻohana pinepine ʻia nā SSD no ka mea he pipiʻi lākou. Ma hope mai, i nā makahiki 1970, kahi mea i kapa ʻia ʻo Electrically Alterable ROM ua hana ʻia e General Instruments. ʻAʻole i lōʻihi kēia. Ma muli o nā pilikia lōʻihi, ʻaʻole i loaʻa ka kaulana o kēia hāmeʻa.
I ka makahiki 1978, ua hoʻohana ʻia ka SSD mua i nā hui ʻaila e kiʻi i ka ʻikepili seismic. I ka makahiki 1979, ua hoʻomohala ka hui ʻo StorageTek i ka RAM SSD mua loa.
RAM Ua hoʻohana ʻia nā SSD e pili ana i ka wā lōʻihi. ʻOiai ua ʻoi aku ka wikiwiki, ua hoʻopau lākou i nā kumuwaiwai CPU a ʻoi aku ka pipiʻi. I ka hoʻomaka ʻana o ka makahiki 1995, ua kūkulu ʻia nā SSD e pili ana i ka flash. Mai ka hoʻokomo ʻia ʻana o nā SSD e pili ana i ka flash, ʻo kekahi mau noi ʻoihana e koi i kahi mea kūʻokoʻa MTBF (ka manawa ma waena o nā hemahema) rate, hoʻololi i nā HDD me nā SSD. Hiki i nā mea hoʻokele paʻa ke kū i ka haʻalulu nui, haʻalulu, hoʻololi wela. No laila hiki iā lākou ke kākoʻo kūpono Nā uku MTBF.
Pehea e hana ai nā Solid State Drives?
Kūkulu ʻia nā SSD ma ka hoʻopaʻa ʻana i nā pahu hoʻomanaʻo i hoʻopili ʻia i loko o kahi pā. Hana ʻia nā ʻāpana me ke silika. Hoʻololi ʻia ka helu o nā ʻāpana i loko o ka waihona e hoʻokō i nā ʻano like ʻole. A laila, hoʻokomo ʻia lākou me nā transistors puka lana e hoʻopaʻa i ka uku. No laila, mālama ʻia ka ʻikepili i mālama ʻia ma SSDs ʻoiai ke kāpae ʻia lākou mai ke kumu mana.
Hiki i kēlā me kēia SSD ke loaʻa kekahi o nā ʻekolu ʻano hoʻomanaʻo – pae hoʻokahi, multi-level a i ʻole ʻekolu-level cell.
ʻekahi. Nā pūnaewele pae hoʻokahi ʻo ia ka wikiwiki a me ka lōʻihi o nā pūnaewele āpau. No laila, ʻo lākou ke kumu kūʻai nui loa. Hoʻokumu ʻia kēia mau mea e paʻa i hoʻokahi wahi o ka ʻikepili i kēlā me kēia manawa.
ʻelua. Nā pūnaewele pae nui hiki ke paʻa i ʻelua mau ʻikepili. No kahi wahi i hāʻawi ʻia, hiki iā lākou ke paʻa i nā ʻikepili ʻoi aʻe ma mua o nā kelepona pae hoʻokahi. Eia naʻe, loaʻa iā lākou kahi pōʻino - lohi kā lākou kākau kākau.
3. ʻĀpana pae ʻekolu ʻo nā mea kūʻai loa o ka hailona. ʻAʻole lōʻihi lākou. Hiki i kēia mau pūnaewele ke hoʻopaʻa i 3 mau ʻikepili i loko o hoʻokahi cell. ʻO ka wikiwiki o kā lākou kākau ʻana.
No ke aha i hoʻohana ʻia ai kahi SSD?
Nā Paʻa Paʻa Paʻa ʻo ia ka mea mālama paʻamau no nā ʻōnaehana, no ka manawa lōʻihi. No laila, inā e neʻe ana nā ʻoihana i SSD, aia paha ke kumu maikaʻi. E ʻike kākou i ke kumu e makemake ai kekahi mau ʻoihana i nā SSD no kā lākou huahana.
Ma kahi HDD kuʻuna, loaʻa iā ʻoe nā kaʻa e wili i ka pā, a neʻe ke poʻo R/W. Ma kahi SSD, mālama ʻia ka mālama ʻana e nā chip memory flash. No laila, ʻaʻohe wahi neʻe. ʻO kēia hoʻonui i ka lōʻihi o ka mea hana.
I loko o nā laptops me ka paʻakikī, e hoʻopau ka mea mālama i ka mana e wili i ka pā. No ka nele o nā SSD i nā ʻāpana neʻe, ʻoi aku ka liʻiliʻi o ka ikaika o nā kamepiula me SSD. ʻOiai e hana ana nā ʻoihana e kūkulu i nā HDD hybrid e hoʻopau i ka mana liʻiliʻi i ka wā e wili ana, ʻOi aku paha ka mana o kēia mau mea hybrid ma mua o ka hoʻokele paʻa.
ʻAe, me he mea lā ʻaʻole loaʻa nā ʻāpana neʻe me ka nui o nā pono. Eia hou, ʻo ka loaʻa ʻole o nā pā wili a i ʻole ka neʻe ʻana i nā poʻo R/W e hōʻike ana e hiki ke heluhelu ʻia ka ʻikepili mai ka drive kokoke koke. Me nā SSD, emi nui ka latency. No laila, hiki i nā ʻōnaehana me SSD ke holo wikiwiki.
Manaʻo ʻia: He aha ka Microsoft Word?
Pono e mālama pono ʻia nā HDD. No ka loaʻa ʻana o nā ʻāpana neʻe, paʻakikī a palupalu. I kekahi manawa, hiki i kahi haʻalulu liʻiliʻi mai kahi kulu ke hōʻino i ka HDD . Akā ʻo SSD ka lima kiʻekiʻe ma aneʻi. Hiki iā lākou ke pale i ka hopena ʻoi aku ka maikaʻi ma mua o nā HDD. Eia nō naʻe, no ka loaʻa ʻana o ka helu o nā pōʻai kākau, ua paʻa ko lākou ola. Hiki ʻole ke hoʻohana ʻia i ka wā e pau ai ke kaʻina kākau.
Nā ʻano o nā SSD
Hoʻopili ʻia kekahi o nā hiʻohiʻona o SSD e ko lākou ʻano. Ma kēia ʻāpana, e kūkākūkā mākou i nā ʻano SSD.
ʻekahi. 2.5 – Ke hoʻohālikelike ʻia i nā SSD āpau ma ka papa inoa, ʻo ia ka lohi. Akā ʻoi aku ka wikiwiki ma mua o HDD. Loaʻa kēia ʻano ma ke kumukūʻai maikaʻi loa no GB. ʻO ia ke ʻano maʻamau o SSD i hoʻohana ʻia i kēia lā.
ʻelua. mSATA - m ku no ka mini. ʻOi aku ka wikiwiki o ka mSATA SSD ma mua o 2.5 mau mea. Ua makemake ʻia lākou i nā mea hana (e like me nā laptops a me nā puke puke) kahi mea ʻaʻole hoʻonani ka lewa. He kumu liʻiliʻi ko lākou. ʻOiai ua hoʻopaʻa ʻia ka papa kaapuni ma 2.5, ʻaʻohe mea i loko o mSATA SSDs. He ʻokoʻa hoʻi kā lākou ʻano pili.
3. SATA III - Loaʻa iā ia kahi pilina pili SSD a me HDD. Ua kaulana kēia i ka wā i hoʻomaka mua ai ka poʻe e hoʻololi i SSD mai HDD. He lohi lohi o 550 MBps. Hoʻopili ʻia ke kaʻa i ka motherboard me ke kaula i kapa ʻia ʻo SATA cable i hiki ke hoʻopili iki.
ʻEhā. PCIe – Ke kū nei ʻo PCIe no Peripheral Component Interconnect Express. ʻO kēia ka inoa i hāʻawi ʻia i ka slot e mālama mau ai i nā kāleka kiʻi, nā kāleka kani, a me nā mea like. Hoʻohana ʻo PCIe SSD i kēia slot. ʻO lākou ka wikiwiki o nā mea a pau a maʻamau, ʻoi aku ka pipiʻi. Hiki iā lākou ke hōʻea i nā wikiwiki ʻaneʻane ʻehā manawa kiʻekiʻe ma mua o ka a SATA kalaiwa .
5. M.2 – E like me ka mSATA drive, loaʻa iā lākou kahi papa kaapuni ʻole. ʻO ka M.2 drive ka mea liʻiliʻi loa o nā ʻano SSD āpau. Ke moe mālie nei kēia i ka motherboard. Loaʻa iā lākou kahi pine hoʻohui liʻiliʻi a lawe i kahi wahi liʻiliʻi loa. Ma muli o ko lākou liʻiliʻi liʻiliʻi, hiki iā lākou ke wela koke, ʻoi aku ka nui o ka wikiwiki. No laila, hele mai lākou me kahi heatsink/heat spreader i kūkulu ʻia. Loaʻa nā M.2 SSD ma SATA a me Nā ʻano PCIe . No laila, ʻokoʻa ka nui a me ka wikiwiki o nā pahu M.2. ʻOiai ʻaʻole hiki i nā mSATA a me 2.5 ke kākoʻo iā NVMe (e ʻike mākou ma hope), hiki i nā drive M.2.
6. NVMe – ʻO NVMe ke kū nei Hōʻike hoʻomanaʻo non-Volatile . ʻO ka huaʻōlelo e pili ana i ka pilina ma o SSD e like me PCI Express a me M.2 hoʻololi ʻikepili me ka mea hoʻokipa. Me kahi kikowaena NVMe, hiki i kekahi ke hoʻokō i nā wikiwiki kiʻekiʻe.
Hiki ke hoʻohana ʻia nā SSD no nā PC āpau?
Inā nui nā SSD e hāʻawi aku, No ke aha i hoʻololi ʻole ai lākou i nā HDD ma ke ʻano he mea mālama nui? ʻO kahi mea pale nui i kēia ke kumu kūʻai. ʻOiai ʻoi aku ka liʻiliʻi o ke kumukūʻai o SSD ma mua o ka mea i loaʻa, i ka wā i komo ai i ka mākeke, ʻO nā HDD ke koho maʻalahi . Ke hoʻohālikelike ʻia i ke kumu kūʻai o kahi paʻa paʻa, hiki i kahi SSD ke kūʻai kokoke ʻekolu a ʻehā mau manawa kiʻekiʻe. Eia kekahi, i kou hoʻonui ʻana i ka hiki o ka hoʻokele, e piʻi koke ke kumukūʻai. No laila, ʻaʻole ia i lilo i koho kālā no nā ʻōnaehana āpau.
Heluhelu pū: E nānā inā he SSD a i ʻole HDD kāu Drive i loko Windows 10
ʻO ke kumu ʻē aʻe i hoʻololi ʻole ai nā SSD i nā HDD ʻo ia ka hiki. Hiki i kahi ʻōnaehana maʻamau me kahi SSD ke loaʻa ka mana ma ka laulā o 512GB a i 1TB. Eia naʻe, ua loaʻa iā mākou nā ʻōnaehana HDD me nā terabytes o ka waiho ʻana. No laila, no ka poʻe e nānā nei i nā mana nui, ʻo HDD mau kā lākou koho.
Nā palena
Ua ʻike mākou i ka mōʻaukala ma hope o ka hoʻomohala ʻana o SSD, pehea i kūkulu ʻia ai kahi SSD, nā pōmaikaʻi i hāʻawi ʻia, a no ke aha i hoʻohana ʻole ʻia ai ma nā PC / laptops āpau. Eia naʻe, hiki mai kēlā me kēia mea hou i ka ʻenehana me kāna mau drawbacks. He aha nā hemahema o ka hoʻokele paʻa?
ʻekahi. Kākau wikiwiki – Ma muli o ka nele o nā ʻāpana neʻe, hiki i kahi SSD ke komo koke i ka ʻikepili. Eia naʻe, haʻahaʻa wale ka latency. Ke kākau ʻia ka ʻikepili ma ka disk, pono e holoi mua ʻia nā ʻikepili mua. No laila, lohi nā hana kākau ma kahi SSD. ʻAʻole ʻike ʻia ka ʻokoʻa wikiwiki e ka mea hoʻohana maʻamau. Akā, he mea pōʻino ke makemake ʻoe e hoʻoili i ka nui o ka ʻikepili.
ʻelua. Nalo a me ka hoʻihoʻi ʻana i ka ʻikepili - Nalo mau ka ʻikepili i holoi ʻia ma nā ʻōhua paʻa. No ka mea ʻaʻohe kope o ka ʻikepili i kākoʻo ʻia, he pōʻino nui kēia. ʻO ka nalowale mau ʻana o ka ʻikepili koʻikoʻi hiki ke lilo i mea weliweli. No laila, ʻo ka ʻoiaʻiʻo ʻaʻole hiki i kekahi ke hoʻihoʻi i ka ʻikepili i nalowale mai kahi SSD kahi palena ʻē aʻe ma aneʻi.
3. Kumukuai – He palena pōkole paha kēia. No ka mea he ʻenehana hou aʻe nā SSDs, he mea maʻamau wale nō ke kumukūʻai ma mua o nā HDD kuʻuna. Ua ʻike mākou ua emi nā kumukūʻai. Malia paha i loko o ʻelua mau makahiki, ʻaʻole e lilo ke kumukūʻai i mea pale no ka poʻe e neʻe i SSD.
ʻEhā. Ka lōʻihi o ke ola Ua ʻike mākou i kēia manawa ua kākau ʻia ka ʻikepili i ka disk ma ka holoi ʻana i ka ʻikepili mua. Loaʻa i kēlā me kēia SSD kahi helu helu kākau / holoi ʻia. No laila, ʻoiai ʻoe e kokoke ana i ka palena o ke kaʻina kākau / holoi ʻana, hiki ke hoʻopilikia ʻia ka hana a SSD. Hele mai kahi SSD ma kahi o 1,00,000 kākau / holoi ʻia. Hoʻopau kēia helu palena i ke ola o kahi SSD.
5. Waihona - E like me ke kumukūʻai, hiki ke lilo hou kēia i ka palena manawa. I kēia manawa, loaʻa nā SSD ma kahi liʻiliʻi liʻiliʻi. No nā SSD o nā mana kiʻekiʻe, pono kekahi e hoʻopuka i nā kālā he nui. ʻO ka manawa wale nō e haʻi inā hiki iā mākou ke loaʻa nā SSD kūpono me ka mana maikaʻi.
Elon Decker He mea kākau ʻenehana ʻo Elon ma Cyber S. Ua kākau ʻo ia pehea e alakaʻi ai ma kahi o 6 mau makahiki i kēia manawa a ua uhi ʻo ia i nā kumuhana he nui. Makemake ʻo ia e uhi i nā kumuhana e pili ana iā Windows, Android, a me nā ʻōlelo hoʻopunipuni hou loa.
