Kwenzeka lokhu nje ukuthi labo abakhiqizi be-SSD abangakatholi amaqembu abo okuthuthukisa isilawuli, kodwa ngesikhathi esifanayo abafuni ukulahlekelwa umbono wemakethe ye-SSD yabathandi, abanakho ukukhetha okukhethekile namuhla. Inketho efanelekayo kubo, ebavumela ukuthi bahlele umhlangano wamadrayivu akhiqiza ngempela nge-interface ye-NVMe, inikezwa yinkampani eyodwa kuphela - i-Silicon Motion, elungele ukunikeza izixazululo eziyinkimbinkimbi ezivela kumlawuli wayo kanye ne-firmware esenziwe ngomumo kuwo wonke umuntu. Ezinye izinkampani, ezifana ne-Phison noma i-Realtek, nazo zinama-chips ayisisekelo atholakala esidlangalaleni okuhlanganisa amadrayivu e-NVMe, kodwa yi-Silicon Motion ehole kule ndawo, enikeza ozakwethu hhayi nje ukusebenza okwengeziwe, kodwa futhi nezixazululo ezisheshayo kakhulu.
Ngasikhathi sinye, phakathi kwezinhlobonhlobo ezinkulu zamadrayivu e-NVMe akhiwe ngesisekelo sabalawuli beSilicon Motion, akuwona wonke amamodeli angase abe nesithakazelo kubathandi. Le nkampani ikhiqiza ama-chips anhlobonhlobo anamazinga ahlukene okusebenza, kodwa amapulatifomu akhethiwe kuphela anganikeza ukusebenza okufanele i-SSD yokulungiselelwa okuthuthukile noma okuphezulu. Ikakhulukazi, ngonyaka odlule sakhuluma ngokufudumele kakhulu ngesilawuli se-SM2262: ngezindinganiso zika-2018, sasibukeka sikhanga kakhulu, sivumela ukushayela okusekelwe kukho ukuthi kusebenze ngokulingana nomthengi ongcono kakhulu we-NVMe SSDs evela kubakhiqizi besigaba sokuqala, kuhlanganise. I-Samsung, i-Western Digital ne-Intel.
Kodwa kulo nyaka isimo sishintshile ngandlela-thile, njengoba abakhiqizi abahamba phambili bebuyekeze amamodeli abo aphezulu aphezulu. Ukuphendula lokhu, i-Silicon Motion yaqala ukunikeza ozakwethu inguqulo ethuthukisiwe yesilawuli sangonyaka odlule, i-SM2262EN, ephinda ithembise ukwanda kwemingcele yokusebenza - ngokuyinhloko ngesivinini sokurekhoda. Kuvela ukuthi amadrayivu asuselwa kule chip okufanele athakazelise abathengi namuhla abalindele ukuba ne-NVMe drive yesimanje futhi esheshayo etholakalayo, kodwa ngasikhathi sinye abafuni ukukhokha ngokweqile ngokuba nomkhiqizo we-A-brand. .
Kuze kube muva nje, ababaningi abakhiqizi abasebenzise isilawuli esisha se-SM2262EN emikhiqizweni yabo. Eqinisweni, ukukhetha kwehlele ezintweni ezimbili: ADATA XPG SX8200 Pro kanye ne-HP EX950. Kodwa manje sekuvele idrayivu yesithathu esekelwe kule chip - i-Transcend ikwazile ukukhiqizwa kwayo. Sizojwayelana nalo mkhiqizo omusha, obizwa nge-Transcend MTE220S, kulokhu kubuyekezwa.
Idatha yokufaka yalo muntu engimaziyo imi kanje. I-HP EX950 ayinikezwa eRussia, kodwa ekuhlolweni kwethu kwakamuva akuzange kubonise noma yimaphi amakhadi ecilongo akhethekile, anikeza ukusebenza ezingeni lokushayela kusilawuli sangaphambilini se-SM2262. Futhi lokhu kusho ukuthi, ngaphandle kokuvela kwenguqulo entsha yesilawuli se-Silicon Image, awekho ama-NVMe SSD angaqhudelana nesisha. , asikakayiboni. Ukuthi i-Transcend MTE220S iphenduka inketho ethakazelisa kakhulu uma iqhathaniswa ne-ADATA XPG SX8200 Pro yinto esizoyithola kulokhu kubuyekezwa. Kepha kufanele kugcizelelwe ngokushesha ukuthi noma ngabe le-SSD ingabonisi imingcele yayo yesivinini, isengaba mnandi kakhulu. Phela, i-Transcend yayizoyithengisa ngentengo ephansi ngokumangazayo - okungenani iphansi ngedrayivu ephelele ene-PCI Express 3.0 x4 interface, i-DRAM buffer kanye nememori ye-TLC enezinhlangothi ezintathu.
