Mukasankha SSD SSD kuti mugwiritse ntchito kunyumba, mungakumane ndi khalidwe monga mtundu wa kukumbukira ntchito ndikudzifunsa nokha ngati MLC kapena TLC ili bwino (mungathe kukumana ndi mayina ena a kukumbukira, mwachitsanzo, V-NAND kapena 3D NAND ). Komanso, posachedwapa makompyuta a QLC akuwoneka bwino kwambiri.
Kuwongolera uku kwa Oyamba kumene kumalongosola mtundu wa kukumbukira kukugwiritsidwa ntchito mu SSD, ubwino ndi zovuta zawo, ndipo ndi njira iti yomwe mungasankhe mukamagula galimoto yoyima. Zingakhalenso zothandiza: Kukhazikitsa SSD kwa Windows 10, Kutsegula Windows 10 kuchokera HDD kupita SSD, Momwe mungadziwire liwiro la SSD.
Mitundu ya chikumbutso cha flash yomwe imagwiritsidwa ntchito mu SSD kuti agwiritse ntchito kunyumba
SSD imagwiritsa ntchito kukumbukira, yomwe ndi maselo osamalidwa bwino omwe amakonzedwa mofanana ndi ma semiconductors, omwe angakhale osiyana mu mtundu.
Nthawi zambiri, kukumbukira kukugwiritsidwa ntchito mu SSD kungagawidwe mwa mitundu iwiriyi.
- Mwa mfundo yowerengera-kulemba, pafupifupi onse ogulitsa SSD ogulitsidwa pamsika ndi a mtundu wa NAND.
- Malinga ndi makina osungirako zinthu, chikumbukirochi chigawikidwa mu SLC (Cell-level level) ndi MLC (Multi-level level). Pachiyambi choyamba, selo ikhoza kusunga pang'ono podziwa, kachiwiri, pangapo. Pankhaniyi, mu SSD kuti mugwiritse ntchito kunyumba, simungapeze SLC memory, MLC yokha.
Komanso, TLC imakhalanso ndi mtundu wa MLC, kusiyana kwake ndikuti m'malo mwa malemba awiri akhoza kusungiramo mfundo zitatu mu memori wa memembala (mmalo mwa TLC mukhoza kuwona 3-bit MLC kapena MLC-3). Ndiko kuti, TLC ndi gawo la MLC.
Chimene chiri bwino - MLC kapena TLC
Kawirikawiri, kukumbukira kwa MLC kumapindula kwambiri pa TLC, makamaka yomwe ili:
- Kuthamanga kwakukulu kwa ntchito.
- Moyo wautali wautumiki.
- Kugwiritsa ntchito mphamvu zochepa.
Chosavuta ndicho mtengo wapamwamba wa MLC poyerekeza ndi TLC.
Komabe, ziyenera kunyalidwa m'maganizo kuti tikukamba za "mlandu waukulu", muzinthu zenizeni zomwe zimagulitsidwa pazomwe mungathe kuziwona:
- Kufulumira kwa ntchito yoyenerera (zina mwa magawo akufanana) kwa SSD ndi TLC ndi MLC memory, yolumikizidwa kudzera SATA-3 mawonekedwe. Kuwonjezera apo, ma drive omwe amachokera ku TLC Memory ndi PCI-E NVMe mawonekedwe nthawi zina amakhala mofulumira kuposa PCI-E MLC amayendetsa ali ndi mtengo ofanana (komabe, ngati tikulankhula za "pamwamba mapeto," SSDs kwambiri komanso otsika kwambiri, iwo akadali MLC kukumbukira kawirikawiri imagwiritsidwa ntchito, koma osati nthawi zonse).
- Nthawi yodalirika (TBW) ya memphane ya TLC imodzi yokonza (kapena mzere umodzi wa ma drive) poyerekeza ndi MLC kukumbukira wina wopanga (kapena mzere wina wa SSDs).
- Mofanana ndi kugwiritsira ntchito mphamvu - mwachitsanzo, galimoto ya SATA-3 ndi TLC kukumbukira kungathe kuwononga mphamvu khumi kuposa momwe PCI-E imayendera ndi MLC. Komanso, kwa mtundu umodzi wa kukumbukira ndi kugwirizanitsa kamodzi, kusiyana kwa mphamvu yogwiritsira ntchito mphamvu kumakhalanso kosiyana malingana ndi kayendetsedwe kake.
Ndipo izi sizinthu zonse: kuthamanga, moyo wautumiki ndi mphamvu zomwe zimagwiritsidwanso ntchito mofulumira zidzasiyananso ndi "mbadwo" wa magalimoto (zatsopanozi nthawi zambiri zimakhala zangwiro: panopa SSD ikupitirizabe kusintha ndi kusintha), chiwerengero chake chonse ndi kuchuluka kwa malo omwe mumagwiritsa ntchito komanso ngakhale mawonekedwe otentha ngati agwiritsidwa ntchito (mofulumira NVMe zoyendetsa).
Zotsatira zake ndizakuti MLC ndi yabwino kuposa MLC sizingathetsedwe - mwachitsanzo, pokhala ndi SSD yambiri komanso yatsopano ndi makhalidwe abwino, mukhoza kupambana pazomwe mukuziyerekezera ndi kugula galimoto ndi MLC pamtengo wofanana, t . Zonsezi ziyenera kuganiziridwa, ndikuyambanso kulingalira ndi bajeti yomwe ikupezeka yogula (mwachitsanzo, ngati mutayankhula ndi bajeti ya ruble zopitirira 10,000, kawirikawiri imayendetsa ndi kukumbukira TLC idzakhala yabwino kwa MLC pa zipangizo zonse za SATA ndi PCI-E).
Kumbukirani SSLC ndi QLC kukumbukira
Kuyambira kumapeto kwa chaka chatha, dziko lolimba limayenda ndi QLC kukumbukira (maselo a quad-level, ie 4 bits mu selo imodzi ya kukumbukira) anawoneka pamsika, ndipo mwinamwake, mu diski 2019 zoterezo zidzakhala zambiri, ndipo mtengo wawo umalimbikitsa kukhala wokongola.
Zogulitsira zomaliza zimadziwika ndi zotsatirazi ndi zotsatirazi poyerekeza ndi MLC / TLC:
- Mtengo wotsika mtengo pa gigabyte
- Kuganiza kwakukulu kwa kukumbukira kuvala ndipo, mwachidwi, kukhala ndi mwayi waukulu wa zolakwika polemba deta
- Limbikitsani kuchepetsa deta
Ziri zovuta kulankhula za nambala, koma zitsanzo zina zomwe zilipo kale pamsika zingaphunzire: Mwachitsanzo, ngati mutenga pafupifupi M.2 SSD ma drive ndi 512 GB kuchokera Intel zochokera QLC 3D NAND ndi TLC 3D NAND kukumbukira, kufufuza zomwe ananena ndi wopanga , tidzawona:
- 6-7 zikwi za ruble motsutsa 10-11,000 rubles. Ndipo pa mtengo wa TLC 512 GB mukhoza kugula 1024 GB QLC.
- Kuwombera kwa chidziwitso cha deta (TBW) ndi 100 TB motsutsana ndi 288 TB.
- Kulemba / kuwerenga mofulumira ndi 1000/1500 motsutsana ndi 1625/3230 MB / s.
Kumbali imodzi, kuipa kungapitirire ubwino wa mtengo. Kumbali ina, mukhoza kulingalira nthawi zoterezi: Ma drive SATA (ngati muli ndi mawonekedwe oterewa) simudzazindikira kusiyana kwa liwiro ndi kuthamanga kwachangu kudzakhala kofunika kwambiri poyerekeza ndi HDD, ndipo parameter ya TBW ya QLC SSD ndi 1024 GB (yomwe ili Chitsanzo chimakhala chimodzimodzi ndi TLC SSD ya 512 GB), kale 200 TB (zikuluzikulu zimayendetsa "kukhala" nthawi yayitali, zomwe zimagwirizana ndi momwe zidalembedwera).
Memory V-NAND, 3D NAND, 3D TLC, ndi zina zotero.
M'mabuku a SSD (makamaka ngati tikuyankhula za Samsung ndi Intel) m'masitolo ndi ndemanga mungapeze chidziwitso V-NAND, 3D-NAND ndi zofanana ndi mitundu ya chikumbutso.
Mainawa amasonyeza kuti maselo okumbukira amawoneka pa chips mu zigawo zingapo (muzipangizo zosavuta, maselo amaikidwa mu chigawo chimodzi, mwatsatanetsatane - pa Wikipedia), pamene iyi ndi TLC yomweyo kapena MLC kukumbukira, koma osati paliponse zomwe zikusonyezedwa momveka bwino: mwachitsanzo, kwa Samsung SSDs, muwona kuti V-NAND kukumbukira, koma zomwe V-NAND TLC zimagwiritsidwa ntchito mu mzere wa EVO ndi V-NAND MLC sichiwonetsedwa nthawi zonse mu PRO. Komanso QLC 3D NAND imatuluka.
Kodi 3D NAND imaposa kukumbukira "planar"? Ndizosavuta kupanga ndi kuyesa kuti lero kuti chikumbukiro cha TLC chisindikizidwe kawirikawiri chimakhala chodalirika komanso chodalirika (Ndiponso, Samsung imanena kuti kukumbukira kwa V-NAND TLC kuli ndi ntchito zabwino zogwirira ntchito zawo) Kukhalitsa kuposa MLC yokonza). Komabe, chifukwa cha kukumbukira kwa MLC, kuphatikizapo mkati mwa zipangizo za wopanga mmodzi, izi sizingakhale choncho. I kachiwiri, izo zimadalira pa chipangizo chodziwika, bajeti yanu ndi magawo ena omwe muyenera kufufuza musanagule SSD.
Ndikanakondwera kulangiza Samsung 970 Pro osachepera 1 TB ngati njira yabwino ya kompyuta kapena laputopu, koma nthawi zambiri ma diski amatsika mtengo, omwe muyenera kusanthula mosamala mbali zonse za makhalidwe ndi kuwayerekeza ndi zomwe zimafunikira pa galimotoyo.
Choncho kusowa yankho lomveka bwino, ndi mtundu wanji wa kukumbukira bwino. Inde, mphamvu ya SSD ndi MLC 3D NAND idzapindula ndi zizindikiro, koma pokhapokha ngati makhalidwewa akulingalira popanda mtengo wa galimoto. Ngati tilingalira izi, sindikutsekereza kuti ena omwe angagwiritsire ntchito ma disks a QLC adzakhala opambana, koma "golide" amatanthauza chikumbukiro cha TLC. Ndipo SSD yomwe mumasankha, ndikupemphani kuti mutenge zinthu zofunika kwambiri.
