Nkhani yatsopano: Ndemanga ya NVMe SSD drive WD Black SN750: yoyendetsedwa, koma osayendetsedwa

2018 yapitayi yakhala nthawi yakukula kwambiri kwa ma drive a NVMe. Panthawiyi, opanga ambiri apanga ndikuyambitsa zinthu zomwe zakweza kwambiri mayankho omwe akugwira ntchito kudzera pa basi ya PCI Express. Mayendedwe amtundu wa ma NVMe SSD apamwamba adayamba kuyandikira mawonekedwe a PCI Express 3.0 x4, ndipo liwiro la magwiridwe antchito mosasamala linakula kwambiri poyerekeza ndi zopereka za mibadwo yam'mbuyomu.

Poganizira izi, sizosadabwitsa kuti mayankho ambiri osangalatsa abwera pamsika. Kuyendetsa bwino kwambiri kwa ogula chaka chatha kunali kopitilira muyeso Intel SSD 760p, WD Black NVMe ndi ADATA XPG SX8200, ndipo onsewa adayang'ana mulingo wamitundu yam'mbuyomu ya NVMe ngati oimira m'badwo watsopano - kuchuluka kwa liwiro kunali koopsa. . Chizindikiro cha kusintha chinalinso chakuti kwa nthawi yoyamba m'zaka zingapo, Samsung idataya mutu wa ogulitsa ma SSD opangidwa ndi misala osangalatsa kwambiri: Samsung 960 EVO drive, yomwe idaperekedwa kwa iyo chaka chatha, idakhala kutali. kuchokera ku njira yabwino kwambiri chifukwa cha kuchuluka kwa omwe akupikisana nawo. Ndipo zikuwoneka kuti kukula kwakukulu komwe kudayamba sikungathenso kuyimitsidwa, ndipo mu 2019 kuwongolera mwachangu kwa ma NVMe SSD opangidwa mochuluka kukapitilirabe.

Komabe, miyezi yoyambirira ya chaka chino ikuwonetsa zosiyana: zikuwoneka kuti opanga ataya zonse zomwe adachita pakupambana kwa chaka chatha, ndipo zomwe tingathe kuziwona posachedwa ndizosintha pang'onopang'ono pazogulitsa za chaka chatha. Simuyenera kuyang'ana kutali kuti mupeze zitsanzo. Lero tiyang'ana Western Digital yaposachedwa kwambiri ya NVMe SSD, WD Black SN750, ndipo ichi ndi chinthu chatsopano chachitatu chaka chino chomwe chapangidwa osapanga kusintha kulikonse pamapangidwe oyambira. Pazinthu zomwe timapeza chaka chino, opanga samatipatsa njira zatsopano komanso zothetsera ma hardware. Chilichonse chimangokhala pakusintha kukumbukira kwa flash kukhala mitundu yamakono, kapenanso kukhathamiritsa pamlingo wa firmware.

Komabe, sitikufuna kunena kuti njira yoteroyo mwachiwonekere sikungapereke zotsatira zabwino. Pali chitsanzo chabwino kwambiri: galimoto yatsopano ya Samsung 970 EVO Plus, yomwe imasiyana ndi yomwe idakonzedweratu posintha 64-wosanjikiza ndi 96-wosanjikiza TLC 3D V-NAND, mosayembekezereka imayika zizindikiro zatsopano za msika wa NVMe SSD. gawo.

Koma izi sizikugwira ntchito nthawi zonse komanso kwa aliyense. Mwachitsanzo, mtundu watsopano wa ADATA XPG SX8200 drive, yomwe idalandira mathero a Pro m'dzina lake, idalandira kukhathamiritsa kwa firmware kotero kuti zikanakhala bwino kusakhala nazo konse. Kuyendetsa kwakhala kothamanga kwambiri kuposa komwe kudalipo kale pama benchmarks, koma sikumapereka kusintha kwenikweni kwa liwiro kapena mawonekedwe ena.

Zomwe Western Digital idachita poyang'ana koyamba zikuwoneka ngati njira ya ADATA. Chowonadi ndi chakuti WD Black SN750 ndi analogue ya WD Black NVMe drive ya chaka chatha (inali ndi nambala yachitsanzo SN720) yokhala ndi firmware yokonzedwa. Komabe, tisathamangire kuganiza; ndani akudziwa momwe izi zingakhudzire magwiridwe antchito. Kupatula apo, Western Digital kamodzi idatipatsa kale zodabwitsa zosayembekezereka komanso zosangalatsa pamene, kutsatira pang'onopang'ono komanso modabwitsa mtundu woyamba wa WD Black PCIe, mtundu wachiwiri wa WD Black NVMe unatulutsidwa, womwe unasintha chilichonse ndikukhala m'modzi mwa ogula kwambiri a NVMe SSD. cha chaka chatha. Choncho, mwamsanga pamene Baibulo lachitatu la "wakuda" Western Digital galimoto anafika Russia, nthawi yomweyo tinaganiza kuyesa izo. Tiyeni tiwone, mwina Western Digital yakwanitsa kupitilira Samsung kachiwiri ndikupanga china chosangalatsa kuposa Samsung 970 EVO Plus?

Zolemba zamakono

Kwa Black NVMe drive (SN720) yomwe idatulutsidwa chaka chatha, Western Digital idasinthiratu nsanja ya Hardware. Wopangayo adayandikira kukulitsa kwa SSD iyi ndi udindo wonse: wowongolera wapadera wokhazikika adapangidwira, omwe, monga adakonzera poyamba, mosiyanasiyana mosiyanasiyana, amayenera kufalitsa pang'onopang'ono malo ake ku ma NVMe SSD ena akampani. Black SN750 yatsopano yomwe tikukamba lero ndiyowona kwathunthu pamapangidwe ake: chigawo chake chofunikira ndi chochokera kwa omwe adayambitsa. Imagwiritsanso ntchito wowongolera yemweyo wa tri-core 28nm, wopangidwa ndi gulu laukadaulo la SanDisk lomwe lidakhala pansi pa mapiko a Western Digital.

Komabe, kusasinthika kwa wowongolera sikungaganizidwe ngati koyipa. Chip cha SanDisk chinachita bwino kwambiri mu 2018 Black NVMe, ndipo ngakhale chinali chochepa cha ARM Cortex-R cores, chinapereka ntchito yabwino kwambiri popanda vuto lililonse.

SSD ndi flash memory sizinasinthe poyerekeza ndi mtundu wakale. Ponseponse komanso pano, Western Digital imagwiritsa ntchito kukumbukira kwa 64-layer BiCS3 (TLC 3D NAND) yokhala ndi chip 256-gigabit chip pakupanga kwake. Ndipo mphindi iyi, kunena zoona, imadzutsa mafunso akuluakulu. Chowonadi ndi chakuti Western Digital idalengeza zobweretsa zoyeserera za 96-wosanjikiza zachinayi cham'badwo wa flash memory (BiSC4) kumbuyo mkati mwa chaka chatha. Ndipo zingakhale zomveka ngati kukumbukira kotereku kumawoneka mumtundu wamakono wamakampani oyendetsa galimoto. Kuphatikiza apo, mnzake wopanga Western Digital, Toshiba, adayamba kupereka ma drive motengera BiCS4 kukumbukira mu Seputembala chaka chatha (mtundu wofananira umatchedwa XG6). Komabe, chinachake chinalakwika ku Western Digital, ndipo kusintha kwa 96-wosanjikiza kung'anima kukumbukira sikunachitike, chifukwa chake Black SN750 yatsopano, ponena za kasinthidwe ka hardware, inakhala yofanana kwambiri ndi yapitayi. chizindikiro "chakuda".

Poteteza chida chake chatsopano, wopangayo akuti kusintha kwakukulu kwachitika pamlingo wa firmware, ndipo gawo lokonzedwanso la pulogalamuyo litha kupereka chiwonetsero chazithunzi zothamanga.
