Paunofunga nezvekuchengetedza matekinoroji, chinhu chekutanga chinouya mupfungwa dzako chichava maSSD, ayo ave akakurumbira zvikuru mumakore achangopfuura. Asi zvakadini kana zvakafanana nemafoni? Ehe, yega yega smartphone / piritsi inoda yekuchengetedza unit. Asi iyo yekuchengetedza unit yakafanana pane ese foni? Kungofanana nemaHDD ekare uye maSDD matsva, pane misiyano yekumhanya?
Evolution yeStorage Technologies
Ehe, kune kukurumidza mutsauko pakati pezviyero zvekuchengetedza pamafoni. Kwemakore, kusimukira kwetekinoroji kwakatipa mamwe epamusoro ekuchengetedza mayuniti uye epamusoro kuverenga / kunyora kumhanya. Zvadaro ngationgororei matekinoroji ekuchengetedza anoshandiswa mumidziyo yeAroid uye kusimudzira kwavo mukutevedzana kwenguva.
eMMC - Yekutanga Smartphone Kuchengeta Tekinoroji
Chekutanga mhando yetekinoroji yekuchengetedza inoshandiswa muma smartphones ndeye eMMC. Kuvepo kweEMMC tekinoroji, iyo yatokura, yakatokura kupfuura yekutanga mafoni. Yekutanga eMMC standard yakagadzirwa neJEDEC neMultiMediaCard Association muna 2006. eMMC (embedded-MMC) is embedded version of the multi-media card (MMC) memory standard.
eMMC inoita seyekutanga chengetedzo yemidziyo inotakurika yakadai sema smartphones kana mahwendefa. eMMC architecture yakasiyana zvakasiyana nedzimwe shanduro dzeMMC. Nekuti kuwedzera zvachose kune chipset, kwete kadhi rinobvisirwa mushandisi. Saka kana iri dambudziko rekuyeuka kana controller, iyo PCB (yakadhindwa redunhu bhodhi) inoda kutsiviwa kana kugadziriswa.
Kutaura nezve eMMC kuchengetedza huwandu, muna 2009 huwandu hweMMC huwandu hwakabva pa2GB kusvika 8GB. Uye muna 2014, avhareji eMMC kugona yakasvika 32GB uye pamusoro, nehukuru huripo huri 128GB. Iyo tekinoroji yekare, zviyero zvakakwirira hazvina kusvika, sezvo zvakatsiviwa nezvitsva.
Kumhanya kwekuverenga nekunyora kunosiyana neMMC shanduro. Yekutanga eMMC protocol yakashandiswa pama smartphones yaive eMMC 4.5. Qualcomm's Snapdragon 800 (MSM8974-AB) chipset inoonekwa seimwe yekutanga chipsets kushandisa eMMC 4.5. Mi 3 (cancro) chishandiso chekutanga kushandisa iyi chipset uye tekinoroji yekuchengetedza padivi reXiaomi. eMMC 4.5 ine 140MB/s kuverenga uye 50MB/s kunyora kumhanya. Izvo zvakatokurumidza kupfuura HDD.
Ipapo imwe vhezheni yayo, eMMC 5.0, yakaunzwa. Iyi tekinoroji yekuchengetedza, iyo yakatanga kuunzwa kune vashandisi vane Snapdragon 801 chipset, inokurumidza kupfuura yakatangira, inosvika 250MB/s kuverenga uye 90MB/s kunyora kumhanya. Chaizvoizvo, uyu ndiwo mutsauko uripo pakati peSnapdragon 800 ne Snapdragon 801. Iyo yakagadziridzwa Snapdragon 800 (MSM8974-AB) chipset ine itsva eMMC vhezheni yakatsikiswa seSnapdragon 801 (MSM8974-AC).
Saizvozvo, Xiaomi's Mi 3 mudziyo, iyo yakagadziridzwa nechipset nyowani uye itsva eMMC, yakaunzwa zvakare seMi 4 LTE. Mi 4 LTE, Xiaomi yekutanga mudziyo uchishandisa eMMC 5.0, zvakare iri Xiaomi yekutanga LTE mudziyo. Zvimwe zvinotsanangurwa zvemudziyo zviripo pano. Uye eMMC 5.1 ndiyo yekupedzisira vhezheni yeiyi tekinoroji yekuchengetedza.
Yazvino eMMC vhezheni ndeye eMMC 5.1. Musiyano kubva kune yakatangira vhezheni inowedzerwa kukurumidza kunyora. eMMC 5.1 ine 250MB/s kuverenga kumhanya uye 125MB/s kunyora kumhanya, ingangoita seSSD. eMMC 5.1 protocol ndiyo yekupedzisira tekinoroji yekuchengetedza nekuti yakatsiviwa neanokurumidza uye yakakura kugona kuchengetedza tekinoroji, UFS!
UFS - Nyowani Era muSmartphone Storage Technologies
Kusikwa kweUFS kwakatangira 2010, asi yakaunzwa nema smartphones muna 2015, nekuburitswa kweUFS 2.0. Kunge eMMC, UFS inoshandisa NAND flash. Yatove UFS yakamisikidzwa kutsiva eMMCs uye SD makadhi. UFS ine yakakwirira bandwidths kupfuura iyo 8-lane parallel uye hafu-duplex interface yeEMMCs. Uye kusiyana eMMC, yakavakirwa paSCSI yekuvaka modhi. Muchidimbu, yaive yakanyanya kufambira mberi uye yaive nepamusoro kuverenga / kunyora kumhanya kupfuura eMMC.
Muna Kukadzi 2013, semiconductor Toshiba Memory (ikozvino Kioxia) kambani yakatanga kutumira samples dze64GB NAND flash chip, yaive yekutanga chip kutsigira chiyero cheUFS panguva iyoyo. Muna Kubvumbi 2015, Samsung Galaxy S6 yakatevedzana yakaburitswa semafoni ekutanga kushandisa UFS 2.0 yakajairwa.
Ehe, Xiaomi yaive kambani yaitevera zviitiko. Inotevera Xiaomi zvishandiso, Mi 5 yakatevedzana yakauya neUFS 2.0 yekuchengetedza tekinoroji. Iine chikwereti ichi kuQualcomm Snapdragon 820 (MSM8996) chipset. UFS 2.0 yakanga ine 350MB/s yekuverenga kumhanya uye 150MB/s kukurumidza kunyora.
Gare gare munaNovember 17, 2016, Qualcomm yakazivisa Snapdragon 835 (MSM8998) chipset ine UFS 2.1. Iyi chipset, iyo yakauya neUFS 2.1 yepamberi, yaive neyakanyanya kuverenga / kunyora kumhanya kupfuura yakatangira. Chekutanga mudziyo kuve neiyi Mi 6 kudivi reXiaomi. UFS 2.1 yakakwanisa kusvika 860 MB/s kumhanya kwekuverenga uye 250 MB/s kumhanya kwekunyora. Aya mamhanyiro ekuverenga / kunyora, ayo akawedzera nekufamba kwenguva, akatungamira kune chaiwo maitiro ekushandisa mumusika weAroid.
UFS yekuchengetedza tekinoroji, iyo yatotanga chaizvo kusimudzira uye kuenderera mberi neUFS 3.0. Iyi protocol, inouya neQualcomm Snapdragon 865 (SM8250) chipset, yakasangana nevashandisi vane kusimudzira kwekusimudzira neSamsung neXiaomi. Samsung Galaxy S20 yakatevedzana yakaunzwa muna Kukadzi 11, 2020 uye Xiaomi Mi 10 nhevedzano yakaunzwa muna Kukadzi 13, 2020. Ese ari maviri emidziyo akatevedzana ane iyi tekinoroji yekuchengetedza. UFS 3.0 ine yakakura kuverenga kumhanya inosvika 2100 MB/s uye inomhanya yekunyora ye410 MB/s. Kusvetukira kukuru kumberi zvichienzaniswa neyakaitangira.
Yazvino UFS vhezheni ndeye UFS 3.1. Tekinoroji yekupedzisira yekuchengetera inouya neQualcomm Snapdragon 865+, Snapdragon 888 uye mushure me chipsets, ichiri kushandiswa nhasi. Musiyano wakanyanya kukosha weUFS 3.1 kuwedzera kukuru kwekumhanya kwekunyora. Kusvika pakumhanya kwekuverenga kwe2100MB/s seUFS 3.0, asi UFS 3.1 ine kukurumidza kunyora kunoshamisa kwe1200MB/s. Nekukurumidza kupfuura mazhinji maSSD nhasi. Xiaomi yakatanga kushandiswa muMi 10T akatevedzana. Nhasi, yave yakajairwa kunyange yepakati-renji michina.
NVMe - Chakavanzika chekumhanya kwe iPhone
NVMe inoreva chizvarwa chinotevera chekuchengetedza tekinoroji. Kana iwe ukafunga nezveNVMe inoshandiswa mumakomputa anhasi, waifungidzira zvakanaka. NVMe ndeyezvishandiso zve iPhone izvo UFS iri kumidziyo yeAroid. Asi kusiyana neAroid UFS, NVMe pa iPhone madivayiri akanyanya kufambira mberi sezvo iri imwe yakadzikira pasi chengetedzo yekombuta kupesana nefoni yakavakirwa UFS. Kusiyana neUFS 3.1, NVMe, Apple yakanyatsogadziriswa pane iyi tekinoroji, iyo inopa inokurumidza kupindura nguva yemidziyo yayo. Muchidimbu, yakafara UFS inoshandiswa pamidziyo yeAroid, yakawanda iPhone-chaiyo NVMe iri.
Ose ari maviri UFS uye NVMe midziyo yekuchengetedza; saka, ine hukama hwepedyo kana zvasvika pakugadzirwa. Asi zvakatora Apple imwe nguva kuigadzira. Pre-iPhone 11 zvishandiso zvaive pazasi peUFS 2.1 kumhanya. Apple yakakwanisa kubata iyi nhanho pane post-iPhone 11 zvishandiso. Mushure me2019, zvaireva kutanga kwemakwikwi eApple.
NVMe kuchengetedza tekinoroji mu iPhone 11 mudziyo yaive ne800MB/s kuverenga uye 500MB/s kunyora kumhanya. Panyaya yekumhanya kwekuverenga, iri padivi neUFS 2.1. Uye kumhanya kwekunyora kunofananidzwa neUFS 3.0. Ikozvino, yazvino Apple mudziyo, iyo iPhone 13 Pro, ine 1600MB/s kuverenga uye 1000MB/s kunyora kumhanya, mumakwikwi neUFS 3.1. Zvimwe zvinotsanangurwa zve iPhone 13 Pro ndizvo pano.
Kuenzanisa kweStorage Technologies
Peta chinyorwa chose pamwe chete, kuenzanisa kwakafara kunogona kuitwa, kubva kukutanga eMMC kuburitswa kune yanhasi UFS 3.1 uye NVMe kumhanya. Nenzira iyi, kukudziridzwa kwekuchengetedza matekinoroji kuchanzwisiswa zviri nani.
| Kuchengetedza Chikamu | Sequential Verenga (MB / s) | Sequential Kunyora (MB / s) |
|---|---|---|
| eMMC 4.5 | 140 MB / s | 50 MB / s |
| eMMC 5.0 | 250 MB / s | 90 MB / s |
| eMMC 5.1 | 250 MB / s | 125 MB / s |
| UFS 2.0 | 350 MB / s | 150 MB / s |
| UFS 2.1 | 860 MB / s | 250 MB / s |
| UFS 3.0 | 2100 MB / s | 410 MB / s |
| Apple NVMe | 1800 MB / s | 1100 MB / s |
| UFS 3.1 | 2100 MB / s | 1200 MB / s |
Tekinoroji dzekuchengetedza dzakagadzirwa kubva kare kusvika ikozvino dziri mumamiriro ezvinhu aya. Kunyangwe NVMe yakanamatira pakati peUFS 3.0 neUFS 3.1, mashandiro emushandisi anogona kusiyana zvichienderana nekugadzikana kwechishandiso. Mafonifoni, ayo asvika kubva pakuremedza kumhanya kweEMMC kuenda kune yakakura kumhanya kweUFS, inosvika pakumhanya kwakanyanya mune ramangwana, UFS 4.0 inogona kuve humbowo hweizvozvo. Saka, Ramba wakatarisa kuti urambe uchifambirana nenguva nezviri kuitika.
