Kugwiritsa ntchito ma drive olimba m'malo osungiramo data sikudzadabwitsanso aliyense. Ma SSD amakhazikika pazida za IT, kuchokera pamakompyuta ndi ma laputopu kupita ku maseva ndi makina osungira deta. Panthawiyi, mibadwo ingapo ya SSD yasintha, yomwe ili ndi makhalidwe abwino pakuchita, kudalirika komanso mphamvu zambiri. Koma nkhani yowunikira chida chojambulira cha SSD ikadali yofunika.
Ma drive amtundu wokhazikika, chifukwa cha mawonekedwe ake, amakhala ndi zida zolembera kale. Ndipo mfundo yakuti zambiri zambiri zalembedwa ku SSD kusiyana ndi zomwe zimatumizidwa kwa izo ndi wolandirayo (makamaka monga gawo la gulu la RAID) zimatifikitsa pafupi kwambiri ndi malire omwe tapatsidwa. Izi ndi mtundu wamantha omwe ogwiritsa ntchito ena amakhala nawo asanagwiritse ntchito ma SSD.
Kwenikweni si zoipa zonse. Chiwonetsero cha DWPD chimaperekedwa kwa nthawi yonse ya chitsimikizo cha galimoto (nthawi zambiri zaka 3-5). Ndipo chifukwa chake, gwero lenileni lojambulira la TBW lidzakhala lochititsa chidwi kwambiri, zomwe zimakulolani kuti musachite mantha "kupukuta" SSD m'miyezi yochepa chabe. Kuphatikiza apo, nthawi zina ndizotheka kugwiritsa ntchito ma drive kwakanthawi mozama kwambiri kuposa momwe wopanga amapangira ndendende chifukwa cha mayendedwe apamwamba a TBW. Komabe, zonsezi sizimathetsa kufunika koyang'anira zojambulira zomwe zilipo za SSD iliyonse ndi cholinga chosinthira mwachangu pamene malire ena afika.
Wogulitsa aliyense wosungirako amagwiritsa ntchito izi mwanjira yake. Koma nthawi zambiri ichi ndi chinthu chabwino / cholakwika choyendetsa. mu awo , m'malo mwake, adapanga chithunzi chonse cha magawo a ntchito yamakono ya SSD mu mawonekedwe a gawo losiyana lotchedwa QSLife. Module iyi ndi gawo lofunikira la makina ogwiritsira ntchito atsopano , pomwe makina onse osungira a Qsan adzagwira ntchito mtsogolo.
Pa SSD iliyonse m'dongosolo, "muyeso wa moyo" wamakono ukuwonetsedwa mu mawonekedwe opezeka kwambiri. Si chinsinsi kuti ma SSD onse amakono amasunga zolemba zawo za midadada yolembedwa kwa iwo. Kutengera ndi mfundo izi, dongosolo kuwerengetsa galimoto kuvala chizindikiro mogwirizana ndi zizindikiro zake. Chotsatira chomaliza chikuwonetsedwa ngati peresenti ya SSD yatsopano. Tikuwonanso kuti kuchuluka kwa kuvala kumawerengedwa osati pa nthawi yomwe galimotoyo idagwira ntchito ngati gawo la All Flash Qsan array, koma kwa moyo wake wonse, kuphatikizapo ntchito monga gawo la machitidwe ena (ngati alipo).
Kuphatikiza pa chidziwitso chosavuta chokhudza kuyendetsa, mutha kudziwanso zambiri. Makamaka, kuchuluka kwa deta yolembedwa pa iyo pa moyo wake wonse wautumiki. Ndipo panthawi yomwe galimotoyo idagwira ntchito ngati gawo la , ma graph a momwe amagwirira ntchito powerenga ndi kulemba alipo. Ziwerengero zimasonkhanitsidwa munthawi yeniyeni ndipo zimapezeka nthawi iliyonse ndikuwonera kuzama mpaka chaka chimodzi.
Zachidziwikire, cholinga cha magwiridwe antchitowa sikuti amangopanga ma graph okongola kuti asangalatse woyang'anira, komanso kusanthula mosamalitsa momwe ma drive amayendera ndikupewa zovuta zomwe zingachitike m'tsogolo zomwe zimagwirizanitsidwa ndi kutha kwawo. Chifukwa chake, pokhudzana ndi "moyo" wa SSD, mutha kuyika mipata yambiri ndikuchita zofanana zokhudzana ndi kutopa kwa chojambulira cha SSD.
Mukayang'ana njira zina zosungirako (osati za All Flash, koma cholinga wamba) , ndiye kuti alibe lipoti lowoneka bwino pamagalimoto. Izi ndi zomveka: pambuyo pa zonse, mbendera iyenera kukhala yosiyana mwanjira ina. Komabe, kuwunika kofananira kumafunikira pamzere wazokhazikika wazogulitsa. Inde, popanda kusonkhanitsa ziwerengero zogwiritsa ntchito ndi magwiridwe antchito. Koma ntchito yayikulu yowunikira chida chojambulira ilipo.
Chifukwa chakusintha kosalekeza kwa matekinoloje opangira ma drive-state drive, funso la kudalirika kwawo latsika pang'ono. Koma, komabe, kuyang'anira gwero la kujambula kwawo kuli kofunikira. Kuwunika kokonzedwa bwino koteroko kudzalola woyang'anira kuti adziwiretu kukalamba kwa SSD pasadakhale malinga ndi katundu weniweni wamakono, ndi oyang'anira kampani kuti awerengere zizindikiro za TCO (ndalama zonse za umwini).
