Njengamanje, ama-SSD athatha kancane kancane amashayela ajwayelekile anzima. Uma nje nje, ama-SSD ayenesayizi encane futhi, njengomthetho, asetshenziselwa ukufaka uhlelo, manje sekukhona kakade amashayela we-terabyte nokunye okuningi. Izinzuzo zamashayela anjalo zicacile - akusizi lutho, ijubane elikhulu futhi liqinisekile. Namuhla sizonikeza amathiphu mayelana nendlela yokwenza ukukhetha okulungile kwe-SSD.
Amanye amathiphu ekukhetheni i-SSD
Ngaphambi kokuthenga i-disk entsha, kufanele uqaphele imingcele eminingi ezokusiza ukuthi ukhethe idivayisi efanele yesistimu yakho:
- Nquma ngesamba se-SSD;
- Thola ukuthi yiziphi izindlela zokuxhumeka ezitholakala kwisistimu yakho;
- Qaphela "disking" disk.
Kungenxa yalezi zimingcele, sizokhetha idrayivu, ngakho ake sibheke ngamunye wabo ngokuningiliziwe.
I-disk ikhono
Ukushayela kombuso okuqinile kunesikhathi eside kunamashayeli avamile, ngakho-ke ngeke ukuwuthenga unyaka owodwa. Yingakho kudingekile ukuthi usondele ngokucophelela ekukhetheni ivolumu.
Uma uhlela ukusebenzisa i-SSD yesistimu nezinhlelo, khona-ke kulokhu, i-128 GB drive izophelela. Uma ufuna ukuthatha indawo ngokuphelele i-disk evamile, khona-ke kulesi simo kufanelekile ukucabangela amadivaysi anomandla we-512 GB noma ngaphezulu.
Ngaphezu kwalokho, ngokungavamile, ivolumu yediski ithinta kokubili ukuphila nokuvinjelwa kokufunda / ukubhala. Iqiniso liwukuthi ngesamba esikhulu sokugcina umlawuli unesikhala esiningi sokusabalalisa umthwalo kumaseli enkumbulo.
Izindlela zokuxhumana
Njengalokhu kunoma iyiphi enye idivayisi, i-SSD yomsebenzi kufanele ixhunywe kukhompyutha. I-interfaces evamile yokuxhumeka yi-SATA ne-PCIe. Amashayela we-PC ayashesha kuno-SATA futhi avame ukwenza njengekhadi. Amashayela we-SATA anokubukeka okumnandi nakakhulu, futhi nawo ahlukahlukene, ngoba angakwazi ukuxhunyaniswa kokubili ikhompyutha ne-laptop.
Noma kunjalo, ngaphambi kokuthenga i-disk, kufanelekile ukuhlola ukuthi kukhona yini izixhumi zamahhala ze-PCIe noma ze-SATA ebhodini le-motherboard.
I-M.2 enye i-SSD yokuxhumeka kokuxhumana okungasebenzisa amabhasi e-SATA ne-PCI-Express (PCIe). Isici esiyinhloko sama diski onesixhumanisi esinjalo ukuhlanganiswa. Ngokuphelele, kunezinketho ezimbili zomxhumanisi - nge-key B ne-M. Zifana nenombolo "yokusika". Uma kuleso simo sokuqala (ukhiye B) kunomshini owodwa, khona-ke okwesibini kukhona ezimbili zazo.
Uma siqhathanisa ijubane lokuxhumeka koxhumano, ke okusheshayo yi-PCIe, lapho izinga lokudluliswa kwedatha lingena ku-3.2 Gb / s. Kodwa i-SATA - kufika ku-600 MB / s.
Uhlobo lokukhumbula
Ngokungafani nama-HDD avamile, idatha igcinwa kwimemori ekhethekile emotweni okusebenza ngokuqinile. Manje ukushayela kuyatholakala ngezinhlobo ezimbili zale nkumbulo - i-MLC ne-TLC. Yiluhlobo lwenkumbulo olukhomba insiza kanye nesivinini sedivaysi. Ukusebenza okuphezulu kuzoba ngama-disks nohlobo lweMLC lokukhumbula, ngakho-ke basebenzisa kangcono uma uvame ukukopisha, ukususa noma ukuhambisa amafayela amakhulu. Noma kunjalo, izindleko zalezi diski ziphakeme kakhulu.
Bheka futhi: I-NAND flash memory memory type
Kumakhompyutha amaningi ekhaya, i-TLC drive iyafezeka. Ngejubane, ziphansi kune-MLC, kodwa zibonakala ziphakeme kunamadivaysi ejwayelekile okugcina.
I-Controller Chip Manufacturers
Akuyona indima yokugcina ekukhetheni i-disc idlala abakhiqizi be-Chip. Ngamunye wabo unenzuzo kanye nenzuzo. Ngakho, abalawuli be-chipSandForce bayathandwa kakhulu. Zinezindleko eziphansi nokusebenza kahle. Isici salezi chips ukusebenzisa ukucindezela kwedatha uma ubhala. Ngesikhathi esifanayo, kunomphumela omkhulu-uma i-disk ingaphezu kwengxenye egcwele, isivinini sokufunda / ukubhala siphume kakhulu.
Ama-Discs nama-chips avela ku-Marvel anejubane elihle kakhulu, elingathinteki ngephesenti lokugcwalisa. Impendulo kuphela lapha yindleko ephezulu.
I-Samsung nayo ikhiqiza ama-chip for drives-state drives. Isici salezo - ukubethela ezingeni lehadiwe. Noma kunjalo, banesici. Ngenxa yezinkinga ezine-algorithm yokuqoqa udoti, isivinini sokufunda / ukubhala singancipha.
I-Fizon chips ifaka ukusebenza okuphezulu kanye nezindleko eziphansi. Azikho izinto ezithinta isivinini, kodwa ngakolunye uhlangothi, azisebenzi kahle ngokubhala okungahleliwe nokufunda.
I-LSI-SandForce yinye isakhi se-chip for controllers-state drive abalawuli. Imikhiqizo evela kulo mkhiqizi ijwayelekile. Esinye sezici ukucindezelwa kwedatha ngenkathi kudluliselwa ku-NAND Flash. Ngenxa yalokho, ivolumu yolwazi olurekhodiwe linciphisa, okuyilokho okusindisa imithombo yedrayivu ngokwayo. Ukungalungi ukwehla kokusebenza kwesilawuli kumthwalo wokugcina imemori.
Futhi ekugcineni, i-chip maker yakamuva i-Intel. Abathengi basekelwe kulezi zinkhukhu zizibonakalisa ngokuqondile kuzo zonke izinhlangothi, kodwa zibiza kakhulu kunezinye.
Ngaphezu kwabalimi abakhulu, kunezinye. Isibonelo, kumamodeli webhajethi yama-disks ungathola abalawuli ngokusekelwe ku-jMicron chips, okwenza umsebenzi wabo kahle, nakuba ukusebenza kwalezi chips kuphansi kunezinye.
Isilinganiso seDrayivu
Cabanga ngezingcingo ezimbalwa ezihamba phambili esigabeni sabo. Njengezigaba sithatha ivolumu yedrayivu ngokwayo.
Ishayela kufika ku-128 GB
Kunamamodeli amabili kulesi sigaba. I-Samsung MZ-7KE128BW ngohla lwamanani kuze kufike kuma-ruble ayizinkulungwane ezingu-8000 futhi angabizi I-Intel SSDSC2BM120A401, izindleko zazo ezihlukahluka kusuka ku-4,000 kuya ku-5 000 ruble.
Isibonelo se-Samsung MZ-7KE128BW sibonakala ngesivinini esiphakeme sokufunda / ukubhala esigabeni sayo. Ngenxa yomzimba omncane, uphelele ukufakwa ku-ultrabook. Kungenzeka ukusheshisa umsebenzi ngokunika i-RAM.
Izici eziyinhloko:
- Funda isivinini: 550 Mbps
- Bhala isivinini: 470 Mbps
- Isivinini sokufunda okungahleliwe: 100,000 IOPS
- Isivinini sokubhala okungahleliwe: 90000 IOPS
IOPS yinombolo yamabhuloki anesikhathi sokubhala noma ukufunda. Okuphakeme kwalesi sibalo, ukuphakama kokusebenza kwedivayisi.
Idrayivu ye-Intel SSDSC2BM120A401 ingenye yezindawo ezinhle kunazo zonke phakathi "kwabasebenzi basezimo" ezinamandla okufinyelela ku-128 GB. Kubonakala ngokuthembeka okuphezulu futhi kuphelele ukufakwa ku-ultrabook.
Izici eziyinhloko:
- Funda isivinini: 470 Mbps
- Bhala isivinini: 165 Mbps
- Isivinini sokufunda okungahleliwe: 80000 IOPS

Ama-Disk anekhono kusuka ku-128 kuya ku-240-256 GB
Lapha ummeleli ohamba kahle yi-drive. I-Sandisk SDSSDXPS-240G-G25, okuyinto izindleko kufinyelela ruble eziyizinkulungwane ezingu-12. Imodeli engabizi kodwa engaphansi kwekhwalithi I-OCZ VTR150-25SAT3-240G (ukufika kuma-ruble ayizinkulungwane ezingu-7).
Izici eziyinhloko ze-CT256MX100SSD1 ebalulekile:
- Funda isivinini: 520 Mbps
- Bhala isivinini: 550 Mbps
- Isivinini sokufunda okungahleliwe: 90000 IOPS
- Isivinini sokubhala okungahleliwe: 100,000 IOPS
Izici eziyinhloko ze-OCZ VTR150-25SAT3-240G:
- Funda isivinini: 550 Mbps
- Bhala isivinini: 530 Mbps
- Isivinini sokufunda okungahleliwe: 90000 IOPS
- Isivinini sokubhala okungahleliwe: 95000 IOPS
Ama-Disk anekhono kusuka ku-480 GB
Kulesi sigaba, umholi ukhona I-CT512MX100SSD1 ebalulekile ngezindleko ezilinganiselwa kuma-ruble angu-17 500. Ukulingana okuphansi I-ADATA Premier SP610 512GB, izindleko zayo zingama-ruble angu-7 000.
Izici eziyinhloko ze-CT512MX100SSD1 ebalulekile:
- Funda isivinini: 550 Mbps
- Bhala isivinini: 500 Mbps
- Isivinini sokufunda okungahleliwe: 90000 IOPS
- Isivinini sokubhala okungahleliwe: 85,000 IOPS
Izici ezibalulekile ze-ADATA Premier SP610 512GB:
- Funda isivinini: 450 Mbps
- Bhala isivinini: 560 Mbps
- Isivinini sokufunda okungahleliwe: 72000 IOPS
- Isivinini sokubhala okungahleliwe: 73000 i-IOPS
Isiphetho
Ngakho, sibheke imigomo eminingana yokukhetha i-SJS. Manje ushiywe ngesipho futhi, usebenzisa ulwazi olutholiwe, unqume ukuthi iyiphi i-SSD engcono kuwe nakusistimu yakho.
