Hangarau SSD i roto i ngā Rorohiko mō te Tere Tere
Pengantar
I tēnei ao hou, kei te piki haere te hiahia mō te tere me te whai huatanga o te whakamahinga rorohiko. Ko tētahi wāhanga e whai wāhi nui ana ki te whakatau i te mahi a te pūnaha rorohiko ko ngā pāpāho rokiroki. Ko ngā Puku Āhua Totoka (SSD) he hangarau kua whakakapi i ngā puku kōpae mārō tuku iho (HDD) i roto i te maha o ngā pūnaha rorohiko nā te mea he tere me te mahi pai rawa atu tā rātou e tuku ana. Ka tirohia e tēnei tuhinga te hangarau SSD, he aha i hiranga ai mō ngā tere teitei, me pēhea hoki e pā ai ki te wheako kaiwhakamahi whānui.
Hītori me te Whanaketanga o te SSD
Tuatahi, me arotake tātou i te hītori me te whanaketanga o ngā SSD. I puta tuatahi mai ngā SSD i te mutunga o te tekau tau atu i 1970 me te tīmatanga o te tekau tau atu i 1980 hei huarahi rokiroki mō ngā tono ahumahi me ngā tono hōia. Heoi, i te tīmatanga, nā te utu nui, kāore i whānuitia te whakamahi i ngā SSD i te mākete kaihoko.
Mai i te tekau tau atu i 2000, me te whanaketanga o te hangarau hanga semiconductor me te hekenga o ngā utu o ngā wāhanga, kua noho ngā SSD hei kōwhiringa whai hua ake mā ngā kaihoko matua. Kua tīmata ngā kamupene pēnei i a Intel, Samsung, me Kingston ki te whakawhanake i ngā SSD iti ake te utu me te whai hua ake, ā, kua māmā ake te uru atu me te rongonui o te hangarau. I ēnei rā, kua noho ngā SSD hei paerewa i roto i te maha o ngā taputapu, mai i ngā pona me ngā rorohiko papamahi ki ngā pūnaha tūmau e hiahia ana ki ngā tere teitei.
Ngā Rerekētanga Matua i waenga i te SSD me te HDD
He rerekē ki ngā HDD, e whakamahi ana i ngā pereti hurihuri me ngā pane pānui/tuhi ā-ringa, ka rongoa ngā SSD i ngā raraunga ki ngā maramara mahara uira NAND. Ko te tikanga kāore he wāhanga neke o ngā SSD, ā, ka tere ake, ka roa ake, ka pakari ake hoki. Me titiro tātou ki ētahi o ngā āhuatanga matua e wehewehe ana i ngā SSD mai i ngā HDD:
1. Tere Pānui/Tuhi: He nui ake te tere pānui/tuhi a ngā SSD i ngā HDD. Ko te tere pānui a te SSD i waenga i te 500 ki te 550 MB/s, ko ngā HDD ia ka eke noa ki te 100 ki te 150 MB/s.
2. Whakaroa: Ko te whakaroa te wā e pau ana i te rokiroki ki te tīmata te whakawhiti raraunga i muri i te whiwhinga o tētahi tono. He iti ake te whakaroa o ngā SSD (te toharite 0.1 ms) i ngā HDD (te toharite 5-10 ms), ko te tikanga ka taea e ngā SSD te tukatuka i ngā mahi whakauru/putanga maha atu ia hekona (IOPS).
3. Te Pakari: Nā te mea kāore he wāhanga neke, he ātete ake ngā SSD ki ngā ru ā-tinana ka kino pea ngā HDD.
4. Te Whai Hua o te Pūngao: Ko te tikanga he iti ake te hiko e pau ana i ngā SSD i ngā HDD, ā, he pai ake te penapena hiko, inā koa i roto i ngā taputapu kawe pēnei i ngā pona.
Ngā momo SSD me ngā hangarau tautoko
He maha ngā momo me ngā āhua o ngā SSD. Anei ētahi o ngā momo matua o ngā SSD e whakamahia whānuitia ana:
1. SATA SSD: Koinei te momo SSD tuatahi i whakamahia whānuitia e ngā kaihoko. Mā te whakamahi i te atanga SATA, ko te tere mōrahi o tēnei SSD he 600 MB/s. Ahakoa he tere ake i ngā HDD, he puhoi ake ngā SATA SSD i ngā SSD hou.
2. NVMe SSD (Non-Volatile Memory Express): He atanga rokiroki a NVMe i hangaia mō ngā SSD, e whakamahi ana i ngā ara PCIe (Peripheral Component Interconnect Express) hei tuku i ngā tere pānui/tuhi teitei ake (tae atu ki te 3500 MB/s me te teitei ake).
3. M.2 SSD: He momo āhua tinana a M.2 e tautoko ana i ngā momo atanga, tae atu ki te SATA me te NVMe. He iti ake ngā M.2 SSD, ā, ka taea te tāuta tika ki runga i te papahoahoa, ka ma ake te āhua, ka nui ake hoki te wāhi i roto i te pouaka rorohiko.
4. U.2 SSD: Ka whakamahia e tēnei SSD he hononga U.2, ā, e kitea ana i ngā tūmau, i ngā teihana mahi rānei e hiahia ana ki te mahi tino pai.
Ngā Painga o te Whakamahi i te SSD i roto i ngā Rorohiko
He maha ngā painga o te whakamahi i tētahi SSD i roto i te rorohiko, ā, ka taea te whakapai ake i te mahi me te wheako kaiwhakamahi:
1. Te Whakaara Tere: Ka taea e ngā SSD te whakapai ake i te wā whakaara o te pūnaha whakahaere mai i ētahi meneti (me ngā HDD) ki ētahi hēkona noa iho. Kāore e hiahiatia ana e ngā kaiwhakamahi te tatari roa kia rite ā rātou rorohiko ki te whakamahi.
2. Te Utaina o ngā Taupānga: Ka tere ake te utaina o ngā taupānga taumaha pēnei i te pūmanawa whakatika ataata, te hoahoa whakairoiro, me ngā kēmu, ka piki ake te hua o te mahi me te wheako petipeti.
3. Whakawhiti Kōnae: He tere ake te neke raraunga mai i tētahi kōpaki ki tētahi atu, he tino whai hua hoki mō te whakahaere i ngā kōnae nunui.
4. Te Whakamahinga o te Mahi Maha: Mā ngā SSD ka taea e te pūnaha te whakahaere pai ake i te mahi maha me te kore e tino whakaroa i te mahi.
Te Pānga o te SSD ki Ētahi Atu Rāngai
Haunga te whakamahinga i roto i ngā rorohiko whaiaro me ngā pona, he pānga pai anō hoki tō ngā SSD ki ētahi atu rāngai pēnei i:
1. Ngā Tūmau me ngā Pokapū Raraunga: Mā ngā SSD ka taea e ngā tūmau me ngā pokapū raraunga te whakahaere i ngā tono maha atu i ngā tere teitei ake me te iti ake o te whakaroa. He mea nui tēnei mō ngā tono pēnei i te manaaki paetukutuku, ngā pātengi raraunga nui, me te rorohiko kapua.
2. Ngā Ahumahi Auaha: Ko te whakatika ataata, te pakiwaituhi 3D, me ētahi atu tono hoahoa e hiahia ana ki te uru tere ki ngā raraunga hei mahi me ngā kōnae nunui. He tino tutuki tēnei hiahia e ngā SSD, ā, ka taea ai te rere mahi pai ake.
3. Te petipeti: I roto i te umanga petipeti, he mea nui te tere o te urunga raraunga hei whakaiti i te wā uta, te whanoke, me te whakapai ake i te wheako petipeti whānui.
4. Te Hanga Pūmanawa: Ka tere ake te mahi a ngā kaihōtaka i te wā e hanga waehere ana, nā te mea ka taea e te SSD te pānui me te tuhi tere i ngā kōnae e hiahiatia ana.
Ngā Wero me te Anamata o ngā SSD
Ahakoa ngā painga maha, he maha ngā wero o ngā SSD. Ko tētahi o ēnei ko te utu teitei ake mō ia GB ki te whakaritea ki ngā HDD. Heoi, kua tino heke ngā utu o ngā SSD, ā, kua iti ake te utu i roto i te wā.
Hei tāpiritanga, kei reira anō te take mō te roa o te mau o te mahara uira e whakamahia ana i roto i ngā SSD. He maha ngā huringa pānui/tuhi o ia pūtau mahara i roto i te maramara NAND i mua i tōna pakaru. Heoi, kua whakawhanakehia ngā hangarau pēnei i te whakataurite kakahu me te whakatikatika hapa hei whakaroa i te roa o te ora o ngā SSD.
He kanapa te heke mai o ngā SSD, me te rangahau me te whanaketanga tonu hei whakapai ake i te mahi, te kaha, me te pono. Ko ngā hangarau hou, pērā i te 3D NAND me te QLC (Quad-Level Cell), ka tuku i te kaha nui ake i ngā utu iti iho.
Whakamutunga
Kua noho te hangarau SSD hei whiringa paerewa mā ngā kaiwhakamahi e rapu ana i te tere tere me te mahi tino pai i roto i ā rātou pūnaha rorohiko. Mā te whānuitanga o ngā momo me ngā āhua e wātea ana, ka taea e ngā kaiwhakamahi te whiriwhiri i te SSD e pai ana mō ā rātou hiahia. Nā te tere, te roa, me te whai huatanga o te pūngao e tukuna ana e ngā SSD, he mea nui rātou i roto i te hangarau rorohiko o ēnei rā. Mā te haere tonu o ngā whanaketanga hangarau me te piki haere o te utu mō ngā SSD, he tino pai te āhua o te heke mai o te rokiroki raraunga matihiko.
