E-China, ukukhiqizwa ngobuningi kwezilawuli zokukhiqizwa kwama-SSD kubaluleke kakhulu njengenhlangano yokukhiqizwa kwasekhaya kwe-NAND flash kanye nenkumbulo ye-DRAM. Ukukhiqizwa okulinganiselwe kwe-32-layer 3D NAND kanye ne-DDR4 chips sekuvele kuqalile ezweni. Kuthiwani ngezilawuli?
Ngokusho kwendawo , e-China, cishe izinkampani eziyishumi zakha izilawuli zama-SSD. Bonke basebenzisa inhlanganisela ethile yama-cores noma izakhiwo ze-ARM (amasethi weziyalezo). Kodwa enye inkampani ikwazile ukumangala: muva nje umthuthukisi kazwelonke ovela e-China wethule abalawuli ngokusekelwe ekwakhiweni kokuqala kwe-microprocessor yase-China, u-Godson.
Izakhiwo zika-Godson noma ama-cores zaba yisisekelo sama-Loongson processors aziwa kabanzi lapho engekho. Ukwakhiwa kwe-Godson kuncike emiyalweni ye-MIPS futhi, empeleni, akukubi kakhulu kubalawuli be-SSD kunokwakheka kwe-ARM. Isilawuli se-IP ye-Godson sakhiwe inkampani yaseShayina i-Guokewei. Lezi yizixazululo ze-GK2302 ezine-interface ye-SATA 6 Gb/s kanye nesivinini sokusebenza esingafika ku-500 MB/s.
Ngokusho kwenkampani, isilawuli se-GK2302 ku-IP Godson sikhiqiza ngo-15% kunomklamo wangaphambilini kuma-ARM cores (GK2301) futhi sisebenzisa amandla angaphansi ngo-6,5%. Alukho olunye ulwazi mayelana ne-GK2302 okwamanje. Ukuze uthole ireferensi, i-GK2301 isekela iziteshi zememori ezine ngokulungiswa kwephutha le-LDPC futhi ikuvumela ukuthi udale ama-SSD anomthamo ofika ku-4 TB (afika ku-32 NAND MLC/TLC/QLC chips). Izixhumi ezibonakalayo ezisekelwayo: ONFI 3.0/Toggle 2.0, kanye ne-SM2/3/4 (okujwayelekile kuzwelonke) nokubethela kwe-SHA-256/AES-256. Okufanayo kungalindelwa kusilawuli esisha.
Amagama ambalwa mayelana nenkampani yaseGuokewei. Yahlelwa ngo-2008, nakuba yangena ekuhwebeni kwezibambiso kuphela ngo-2017. Le nkampani igxile ekuthuthukiseni ama-chips amabhokisi aphezulu, izinhlelo zokugcina idatha, izilawuli zezinzwa nezinto ezixhunywe ku-inthanethi. Ngo-2018, inzuzo kaGuokewei yayilinganiselwa ku-$ 57,68. Ngesikhathi esifanayo, inkampani ithola uxhaso lwezimali zikahulumeni waseShayina, ezivumela ukuthi iqhubekele phambili ngaphandle kokubheka inzuzo.
