Ke noʻonoʻo ʻoe i nā ʻenehana mālama, ʻo ka mea mua e hiki mai i kou noʻonoʻo ʻo SSDs, i kaulana loa i nā makahiki i hala. Akā pehea inā like ia me nā kelepona? ʻOiaʻiʻo, pono kēlā me kēia kelepona / papa i kahi waihona mālama. Akā ua like ka waihona waihona ma kēlā me kēia kelepona? E like me nā HDD kahiko a me nā SSD hou, aia nā ʻokoʻa wikiwiki?
Hoʻoulu ʻana o nā ʻenehana mālama
ʻOiaʻiʻo, aia nā ʻokoʻa wikiwiki ma waena o nā ʻāpana mālama ma nā kelepona. I loko o nā makahiki, ua hāʻawi mai nā hoʻomohala ʻenehana iā mākou i nā ʻāpana waihona ʻoi aku ka holomua a me ka wikiwiki heluhelu/kākau. A laila e nānā i nā ʻenehana mālama i hoʻohana ʻia i nā polokalamu Android a me kā lākou hoʻomohala ʻana ma ke ʻano chronological.
eMMC - ʻenehana mālama mālama kelepona mua
ʻO ke ʻano mua o nā ʻenehana mālama i hoʻohana ʻia i nā kelepona ʻo eMMC. ʻO ka loaʻa ʻana o ka ʻenehana eMMC, kahi mea kahiko loa, ʻoi aku ka ʻoi aku o ka ʻoi ma mua o nā kelepona mua. Ua hoʻomohala ʻia ka maʻamau eMMC mua e JEDEC a me ka MultiMediaCard Association i ka makahiki 2006. ʻO eMMC (embedded-MMC) ka mana hoʻopili o ka mana hoʻomanaʻo multi-media card (MMC).
Hana ʻo eMMC ma ke ʻano he waihona mua no nā polokalamu kelepona e like me nā smartphones a i ʻole papa. He ʻokoʻa ka hoʻolālā eMMC mai nā mana ʻē aʻe o MMC. No ka mea, he hoʻohui mau ia i ka chipset, ʻaʻole he kāleka hiki ke hoʻohana ʻia. No laila, inā pilikia ka hoʻomanaʻo a i ʻole ka mea hoʻoponopono, pono e hoʻololi a hoʻoponopono ʻia ka PCB (paʻi kaapuni.
Ma ke kamaʻilio ʻana e pili ana i ka hiki ke mālama ʻia eMMC, i ka makahiki 2009, ʻo ka awelika o ka mana eMMC mai 2GB a 8GB. A i ka makahiki 2014, hiki i ka 32GB a ma luna o ka mana eMMC awelika, me ka nui o kēia manawa he 128GB. He ʻenehana kahiko ia, ʻaʻole i hiki i nā ana kiʻekiʻe, no ka mea ua pani ʻia lākou e nā mea hou.
ʻOkoʻa ka wikiwiki o ka heluhelu a kākau ʻana e nā mana eMMC. ʻO ka protocol eMMC mua i hoʻohana ʻia ma nā kelepona ʻo eMMC 4.5. Manaʻo ʻia ʻo Qualcomm's Snapdragon 800 (MSM8974-AB) chipset kekahi o nā chipsets mua e hoʻohana i ka eMMC 4.5. ʻO Mi 3 (cancro) ka mea mua e hoʻohana i kēia chipset a me ka ʻenehana mālama ma ka ʻaoʻao Xiaomi. Loaʻa i ka eMMC 4.5 he 140MB/s heluhelu a he 50MB/s ka wikiwiki kākau. ʻOi aku ka wikiwiki ma mua o kahi HDD.
A laila ua hoʻokomo ʻia kahi mana hou o ia mea, eMMC 5.0. ʻO kēia ʻenehana mālama, i hoʻolauna mua ʻia i nā mea hoʻohana me ka chipset Snapdragon 801, ʻoi aku ka wikiwiki ma mua o kona mua, hiki i ka 250MB / s heluhelu a me ka wikiwiki kākau 90MB / s. ʻOiaʻiʻo, ʻo kēia ka ʻokoʻa ma waena o Snapdragon 800 a me Snapdragon 801. ʻO ka chipset Snapdragon 800 (MSM8974-AB) hou me ka mana eMMC hou ua hoʻokuʻu hou ʻia e like me Snapdragon 801 (MSM8974-AC).
Pēlā nō, ua hoʻokomo hou ʻia ka polokalamu Xiaomi Mi 3, i hōʻano hou ʻia me ka chipset hou a me ka eMMC hou e like me Mi 4 LTE. ʻO Mi 4 LTE, ʻo Xiaomi ka mea mua e hoʻohana ana i ka eMMC 5.0, ʻo ia hoʻi ka polokalamu LTE mua o Xiaomi. Loaʻa nā kikoʻī ʻē aʻe o ka hāmeʻa maanei. A ʻo eMMC 5.1 ka mana hope loa o kēia ʻenehana mālama.
ʻO ka mana eMMC hou loa ʻo eMMC 5.1. Hoʻonui ʻia ka ʻokoʻa mai kona mana ma mua. Loaʻa i ka eMMC 5.1 ka wikiwiki heluhelu he 250MB/s a me ka wikiwiki kākau 125MB/s, ʻaneʻane like me SSD. ʻO ka eMMC 5.1 protocol ka ʻenehana hoʻopaʻa hope loa no ka mea ua hoʻololi ʻia e kahi ʻenehana mālama ʻoi aku ka wikiwiki a ʻoi aku ka nui, UFS!
UFS - Ke Au Hou i nā ʻenehana mālama kelepona
Hoʻokumu ʻia ka UFS i ka makahiki 2010, akā ua hoʻokomo ʻia me nā smartphones ma 2015, me ka hoʻokuʻu ʻana o UFS 2.0. E like me eMMC, hoʻohana ʻo UFS i ka uila NAND. Ua hoʻonoho ʻia ʻo UFS e pani i nā eMMC a me nā kāleka SD. Loaʻa i ka UFS nā bandwidth kiʻekiʻe ma mua o ka 8-lane parallel a me ka hapalua-duplex interface o eMMC. A ʻaʻole like me eMMC, ua hoʻokumu ʻia ma ke kumu hoʻohālike SCSI. I ka pōkole, ʻoi aku ka holomua a ʻoi aku ka kiʻekiʻe o ka heluhelu / kākau ʻana ma mua o eMMC.
I Pepeluali 2013, hoʻomaka ka hui semiconductor Toshiba Memory (ʻo Kioxia i kēia manawa) i nā laʻana o 64GB NAND flash chip, ʻo ia ka chip mua e kākoʻo i ka maʻamau UFS i kēlā manawa. I ʻApelila 2015, ua hoʻokuʻu ʻia ka moʻo Samsung Galaxy S6 e like me nā kelepona mua e hoʻohana i ka maʻamau UFS 2.0.
ʻOiaʻiʻo, he hui ʻo Xiaomi i hahai i nā hanana. ʻO nā polokalamu Xiaomi aʻe, hele mai ʻo Mi 5 me ka ʻenehana mālama mālama UFS 2.0. He aie ia i ka Qualcomm Snapdragon 820 (MSM8996) chipset. Ua loaʻa iā UFS 2.0 ka wikiwiki heluhelu 350MB/s a me ka wikiwiki kākau 150MB/s.
Ma hope o Nowemapa 17, 2016, ua hoʻolaha ʻo Qualcomm iā Snapdragon 835 (MSM8998) chipset me UFS 2.1. ʻO kēia chipset, i hele mai me ka UFS 2.1 kiʻekiʻe aʻe, ʻoi aku ka kiʻekiʻe o ka heluhelu / kākau ʻana ma mua o kona mua. ʻO ka mea mua e loaʻa i kēia Mi 6 ma ka ʻaoʻao Xiaomi. Ua hiki i ka UFS 2.1 ke hiki i ka 860 MB/s ka wikiwiki heluhelu a me ka 250 MB/s ka wikiwiki kākau. ʻO kēia mau wikiwiki heluhelu / kākau, i hoʻonui i ka manawa, ua alakaʻi i nā mea hana maoli ma ka mākeke Android.
ʻO ka ʻenehana mālama mālama UFS, ua hoʻomaka maoli nei e hoʻomohala a hoʻomau i kāna ala me UFS 3.0. ʻO kēia protocol, e hele mai me Qualcomm Snapdragon 865 (SM8250) chipset, ua hālāwai me nā mea hoʻohana me nā hoʻolaha assertive e Samsung a me Xiaomi. Ua hoʻokomo ʻia ka moʻo Samsung Galaxy S20 ma Pepeluali 11, 2020 a me Xiaomi Mi 10 series i hoʻokomo ʻia ma Pepeluali 13, 2020. Loaʻa i nā ʻāpana ʻelua kēia ʻenehana mālama. Loaʻa iā UFS 3.0 ka wikiwiki heluhelu nui a hiki i 2100 MB/s a me ka wikiwiki kākau o 410 MB/s. He lele nui ia i mua e hoʻohālikelike ʻia i kona mua.
ʻO ka mana UFS o kēia manawa ʻo UFS 3.1. Hele mai ka ʻenehana waihona hou me Qualcomm Snapdragon 865+, Snapdragon 888 a ma hope o nā chipsets, hoʻohana mau ʻia i kēia lā. ʻO ka ʻokoʻa nui loa o ka UFS 3.1 ka piʻi nui o ka wikiwiki kākau. Loaʻa i ka wikiwiki heluhelu o 2100MB/s e like me UFS 3.0, akā ʻo UFS 3.1 ka wikiwiki kākau o 1200MB/s. ʻOi aku ka wikiwiki ma mua o ka hapa nui o nā SSD i kēia lā. Ua hoʻohana mua ʻia ʻo Xiaomi ma Mi 10T series. I kēia lā, ua lilo ia i mea maʻamau a hiki i nā mea waena waena.
NVMe - Ka mea huna o ka wikiwiki o iPhone
Hōʻike ʻo NVMe i ka ʻenehana mālama mālama hou. Inā ʻoe e noʻonoʻo i ka NVMe i hoʻohana ʻia i nā kamepiula o kēia lā, ua kuhi pololei ʻoe. ʻO NVMe i nā polokalamu iPhone he aha ka UFS i nā polokalamu Android. Akā ʻaʻole e like me Android UFS, ʻoi aku ka holomua o ka NVMe ma nā polokalamu iPhone no ka mea he mea hoʻoemi i ka mālama kamepiula ma mua o ka UFS. ʻAʻole like me UFS 3.1, NVMe, ua paʻa loa ʻo Apple i kēia ʻenehana, e hāʻawi ana i ka manawa pane wikiwiki loa no kāna mau polokalamu. I ka pōkole, ʻoi aku ka nui o ka UFS i hoʻohana ʻia ma nā polokalamu Android, ʻoi aku ka nui o ka iPhone-specific NVMe.
ʻO UFS a me NVMe nā mea mālama; no laila, loaʻa nā dynamics kokoke i ka wā e hana ai. Akā ua lawe ʻo Apple i kahi manawa e hoʻomohala ai. ʻOi aku ka mamao ma lalo o ka wikiwiki o UFS 11 i nā polokalamu pre-iPhone 2.1. Ua hiki iā Apple ke hopu i kēia manawa ma nā polokalamu post-iPhone 11. Ma hope o 2019, ʻo ia ka hoʻomaka ʻana o ka hoʻokūkū no Apple.
ʻO ka ʻenehana mālama mālama NVMe ma ka iPhone 11 he 800MB/s heluhelu a me ka wikiwiki kākau 500MB/s. Ma nā ʻōlelo o ka wikiwiki heluhelu, ua like ia me UFS 2.1. A ua like ka wikiwiki kākau me UFS 3.0. I kēia manawa, ʻo ka polokalamu Apple hou loa, ʻo ka iPhone 13 Pro, he 1600MB/s heluhelu a me ka wikiwiki kākau 1000MB/s, i ka hoʻokūkū me UFS 3.1. ʻO nā kikoʻī ʻē aʻe o iPhone 13 Pro maanei.
Hoʻohālikelike o nā ʻenehana mālama
Hoʻopili i ka ʻatikala holoʻokoʻa, hiki ke hoʻohālikelike ākea, mai ka hoʻokuʻu mua ʻana o ka eMMC a hiki i kēia lā UFS 3.1 a me NVMe wikiwiki. Ma kēiaʻano, e hoʻomaopopo maikaʻiʻia ka hoʻomohalaʻana i nāʻenehana mālama.
| Wahi mālama | Heluhelu Kāʻe (MB / s) | Kākau Pelekikena (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 |
| ʻO Apple NVMe | 1800 MB / s | 1100 MB / s |
| UFS 3.1 | 2100 MB / s | 1200 MB / s |
ʻO nā ʻenehana mālama i hoʻomohala ʻia mai ka wā kahiko a hiki i kēia manawa i kēia kūlana. ʻOiai ua paʻa ʻo NVMe ma waena o UFS 3.0 a me UFS 3.1, ʻokoʻa paha ka hana o ka mea hoʻohana ma muli o ke kūpaʻa o ka hāmeʻa. ʻO nā kelepona, i hōʻea mai ka wikiwiki o ka eMMC i nā wikiwiki nui o UFS, e piʻi i nā wikiwiki kiʻekiʻe i ka wā e hiki mai ana, hiki i ka UFS 4.0 ke hōʻoia i kēlā. No laila, e hoʻomau i ka hoʻomau ʻana i nā mea hoʻomohala.
