Mukamasankha SSD yolimba ya stateD kuti muzigwiritsa ntchito kunyumba, mutha kupeza mawonekedwe monga mtundu wa kukumbukira komwe ukugwiritsidwa ntchito ndikudzifunsa kuti ndibwino - MLC kapena TLC (mungapezenso zosankha zina pakupanga mtundu wa kukumbukira, mwachitsanzo, V-NAND kapena 3D NAND ) Posachedwa adawoneka okongola pamitengo yokhala ndi kukumbukira QLC.
Mukuwunikanso kwa oyamba kumene, tidzakufotokozerani zamitundu yama memory omwe amagwiritsidwa ntchito mu ma SSD, maubwino ndi zovuta zake, ndi njira iti yomwe ingakhale yabwino mukamagula mawonekedwe olimba a boma. Zitha kuthandizanso: Kukhazikitsa SSD ya Windows 10, Momwe mungasinthire Windows 10 kuchokera ku HDD kupita ku SSD, Momwe mungadziwire kuthamanga kwa SSD.
Mitundu yama memory memory omwe amagwiritsidwa ntchito mu SSD pakugwiritsa ntchito kunyumba
SSD imagwiritsa ntchito kukumbukira kwa flash, yomwe ndi khungu lolinganizidwa mwapadera molingana ndi ma semiconductors, omwe amatha kusiyanasiyana.
Mwambiri, kukumbukira kwama Flash komwe kumagwiritsidwa ntchito mu SSDs kumatha kugawidwa m'magulu otsatirawa.
- Pogwiritsa ntchito mfundo zakuwerenga, pafupifupi ma SSD onse omwe amagulitsa malonda ndi mtundu wa NAND.
- Malinga ndi ukadaulo wosungira zidziwitso, kukumbukira kumagawidwa mu SLC (Cell-single Cell) ndi MLC (Multi-Level Cell). Poyambirira, khungu limatha kusunga zidziwitso zochepa, chachiwiri - zoposa chimodzi. Nthawi yomweyo, mu SSD yogwiritsira ntchito nyumba simudzapeza kukumbukira kwa SLC, MLC yokha.
Nawonso TLC ilinso ya mtundu wa MLC, kusiyana ndikuti m'malo mwa ma bati 2 a chidziwitso imatha kusunga ma bits atatu a chidziwitso pamalo a kukumbukira (m'malo mwa TLC mutha kuwona kutchulidwa kwa 3-bit MLC kapena MLC-3). Ndiye kuti, TLC ndi subspecies ya MLC memory.
Zomwe zili bwino - MLC kapena TLC
Mwambiri, kukumbukira kwa MLC kuli ndi zabwino pa TLC, zazikulu zomwe ndi:
- Kuthamanga kwambiri.
- Moyo wautali kwambiri.
- Kugwiritsa ntchito mphamvu zochepa.
Zoyipa zake ndizokwera mtengo kwa MLC poyerekeza ndi TLC.
Komabe, ziyenera kukumbukiridwa kuti tikulankhula za "general kesi", mu zida zenizeni zogulitsa zomwe mutha kuziwona:
- Kuthamanga kofanana ntchito (zinthu zina kukhala zofanana) kwa ma SSD okhala ndi TLC ndi kukumbukira kwa MLC wolumikizidwa kudzera pa mawonekedwe a SATA-3. Kuphatikiza apo, ma drive amtundu wa TLC omwe ali ndi PCI-E NVMe nthawi zina amatha kuthamanga kuposa ma drive amtengo wofanana ndi PCI-E MLC (komabe, tikalankhula za "kumapeto", ma SSD okwera mtengo kwambiri, akadali Kukumbukira kwa MLC nthawi zambiri kumagwiritsidwa ntchito, komanso osati nthawi zonse).
- Nthawi Yotsimikiziranso Yotsimikizika (TBW) ya kukumbukira kwa TLC kuchokera kwa wopanga m'modzi (kapena mzere umodzi) poyerekeza ndi kukumbukira kwa MLC kuchokera kwa wopanga wina (kapena mzere wina wa SSD).
- Zofanana ndi kugwiritsa ntchito mphamvu - mwachitsanzo, kuyendetsa kwa SATA-3 yokhala ndi kukumbukira kwa TLC kumatha kugwiritsa ntchito mphamvu zochepa kuwirikiza kakhumi kuposa PCI-E drive yokhala ndi kukumbukira kwa MLC. Kuphatikiza apo, pamachitidwe amodzi amakumbukidwe ndi mawonekedwe amtundu umodzi, kusiyana kwa kugwiritsidwa ntchito kwa magetsi kumakhalanso kosiyana kwambiri kutengera kuyendetsa kwina.
Ndipo awa si magawo onse: kuthamanga, moyo wautumiki ndi kugwiritsa ntchito mphamvu kudzasiyananso ndi "m'badwo" wagalimoto (zatsopano, monga lamulo, zimakhala zangwiro kwambiri: pakadali pano ma SSD akupitiliza kukulira ndikusintha), voliyumu yake yonse ndi kuchuluka kwa malo aulere mukamagwiritsa ntchito ndi ngakhale nyengo yotentha mukamagwiritsa ntchito (pakuyendetsa mwachangu NVMe).
Zotsatira zake, chigamulo chokhwima komanso cholondola kuti MLC ndiwabwino kuposa TLC sichingatheke - mwachitsanzo, pogula SSD yatsopano komanso TLC yokhala ndi machitidwe abwino, mutha kupambana pazonse poyerekeza kugula drive ndi MLC pamtengo womwewo, t .e. magawo onse ayenera kukumbukiridwa, ndipo kusanthula kuyenera kuyambitsidwa ndi ndalama zogulira zogula (mwachitsanzo, polankhula za bajeti yokwana ma ruble 10,000, nthawi zambiri ma drive omwe ali ndi memory ya TLC angakonde MLC pazida zonse za SATA ndi PCI-E).
Ma SSD okhala ndi kukumbukira kwa QLC
Kuyambira kumapeto kwa chaka chatha, ma drive-solid state state okhala ndi QLC memory (quad-level cell, i.e. mabatani anayi mu cell limodzi lama memory) adawonekera pa malonda, ndipo, mwina, mu 2019 padzakhala zokuwongolera zambiri, ndipo mtengo wawo umalonjeza kuti uzikhala wokongola.
Malonda omaliza amadziwika ndi zotsatirazi zabwino ndi zowawa poyerekeza ndi MLC / TLC:
- Kutsika mtengo pa gigabyte iliyonse
- Kukumbukira kokulirapo komwe kungakhale kovala ndipo, makamaka, ndizowopsa zolakwitsa polemba
- Kuthamanga kwapa data mwachangu
Zimakhalabe zovuta kunena za manambala, koma zitsanzo zina za zomwe zilipo kale zitha kuwerengedwa: mwachitsanzo, ngati mutatengetsa pafupifupi 512 GB M.2 SSD kuyendetsa kuchokera ku Intel kutengera kukumbukira kwa QLC 3D NAND ndi TLC 3D NAND, werengani zomwe wopanga adziwe onani:
- 6-7,000 ma ruble motsutsana ndi 10 rubles 10,000. Ndipo mtengo wa 512 GB TLC, mutha kugula 1024 GB QLC.
- Kuchuluka kwa kuchuluka kolemba (TBW) ndi 100 TB motsutsana ndi 288 TB.
- Kuthamanga kwa kulemba / kuwerenga ndi 1000/1500 poyerekeza ndi 1625/3230 Mb / s.
Komabe, chithandiziro chitha kupitilira phindu la mtengo wake. Kumbali inayi, mutha kukumbukira nthawi ngati izi: za ma disATA a SATA (ngati mungokhala ndi mawonekedwe oterowo) simudzazindikira kusiyana kwake komanso kuthamanga kwake kudzakhala kofunikira kwambiri poyerekeza ndi HDD, ndipo gawo la TBW la QLC SSD ndi 1024 GB (yomwe mu wanga Mtunduwo umawononga ndalama zofanana ndi 512 GB TLC SSD) 200 TB (zikuluzikulu zikuluzikulu zimayendetsa "moyo" motalikirapo, chifukwa cha momwe zalembedwera pa iwo).
V-NAND memory, 3D NAND, 3D TLC, etc.
M'mafotokozedwe amayendedwe a SSD (makamaka ikafika pa Samsung ndi Intel) m'masitolo ndikuwunika mungapeze dzina la V-NAND, 3D-NAND ndi ofanana ndi mitundu yamai.
Izi zikuwonetsa kuti maselo a kukumbukira a flash ali pa tchipisi tating'ono tambiri (mu tchipisi tosavuta, maselo ali mumtambo umodzi, zambiri pa Wikipedia), pomwe iyi ndi makumbukidwe amodzi a TLC kapena MLC, koma sizowonetsedwa ponseponse: mwachitsanzo, a Samsung SSDs, mudzangoona kuti kukumbukira kwa V-NAND kumagwiritsidwa ntchito, koma zambiri za V-NAND TLC mu mzere wa EVO ndi V-NAND MLC mu mzere wa Pro sizowonetsedwa nthawi zonse. Komanso tsopano ma drive a QLC 3D NAND aonekera.
Kodi 3D NAND ndiyabwino kuposa chikumbutso cha mapulaneti? Ndiwotsika mtengo kwambiri kuti apange ndipo mayeso akuonetsa kuti masiku ano kukumbukira kwa TLC, njira yosanja masanjidwe ambiri nthawi zambiri imakhala yabwino komanso yodalirika (Komanso, Samsung imanena kuti kukumbukira kwa V-NAND TLC kumatha kuchita bwino komanso moyo wautumiki kuposa mapulani a MLC). Komabe, kukumbukira kwa MLC, kuphatikiza mkati mwa zida za wopanga yemweyo, izi sizingakhale choncho. Ine.e. Komanso, zonse zimatengera chipangizocho, bajeti yanu ndi magawo ena omwe amayenera kuphunzira musanagule SSD.
Ndingakhale wokondwa kupangira Samsung 970 Pro osachepera 1 TB ngati njira yabwino pakompyuta ya kunyumba kapena laputopu, koma nthawi zambiri mitengo yotsika mtengo imagulidwa, yomwe muyenera kuiphunzira mosamala ndi machitidwe onse ndikuwayerekeza ndi zomwe zimafunikira kuchokera pagalimoto.
Chifukwa chake kusowa yankho lomveka, ndipo kukumbukira kwake ndi kotani. Zachidziwikire, SSD yokhala ndi MLC 3D NAND molingana ndi mndandanda wopambana udzapambana, koma malinga ngati mawonekedwe awa amawerengedwa pazokha kuchokera pamtengo woyendetsa. Ngati tiganizira izi, sindipatula mwayi woti diski ya QLC ikhale yabwino kwa ogwiritsa ntchito, koma "malo apakati" ndi kukumbukira kwa TLC. Ndipo ziribe kanthu kuti ndi SSD iti yomwe mungasankhe, ndikulimbikitsa kutenga ma backups ofunika ofunikira.
