Hajoale, li-drive tsa 'muso tse tiileng kapa li-SSD li ntse li tsebahala haholo (Solid State Drive). Sena se bakoa ke taba ea hore ba khona ho fana ka lebelo le phahameng la ho bala / ho ngola la lifaele le ho ts'epahala. Ho fapana le likoloi tse thata tse tloaelehileng, ha ho na lintho tse tsamaeang, 'me mohopolo o khethehileng oa flash - NAND e sebelisoa ho boloka data.

Nakong ea ho ngola, SSD e sebelisa mefuta e meraro ea memori ea Flash: MLC, SLC, le TLC, mme sehloohong sena re tla leka ho fumana hore na ke eng e ntle le hore na phapang e teng pakeng tsa bona ke efe.

Kakaretso ea Papiso ka SLC, MLC, le TLC Memory Mefuta

Memori ea Flash ea NAND e rehiloe lebitso ka mor'a mofuta o ikhethileng oa data markup - Eseng LE (ea utloahala HONA LE). Ntle le ho kena dintlha tsa tekheniki, a re re NAND e hlophisa data ka li-block tse nyane (kapa maqephe) mme eu lumella ho fihlella lebelo le phahameng la ho bala data.

Joale a re shebeng hore na ke mefuta efe ea memori e sebelisitsoeng ho li-drive tsa state state tse thata.

Sele e le 'ngoe (SLC)

SLC ke mofuta oa khale oa memori o sebelisang lisele tsa memori tse boemo bo le bong ho boloka tlhaiso-leseling (ka tsela, phetolelo ea mantlha ho Serussia e utloahala joaloka "sele e le 'ngoe"). Ka mantsoe a mang, ho ne ho bolokiloe data e le 'ngoe. Mokhatlo o joalo oa polokelo ea data o entse hore o khone ho fana ka lebelo le phahameng le sesebelisoa se seholo sa ho ngola. Ka hona, lebelo la ho bala le fihla ho 25 ms, mme nomoro ea lipotoloho tse ngotsoeng hape ke 100'000. Leha ho le joalo, leha e sa rarahane, SLC ke mofuta o theko e boima haholo oa memori.

Melemo:

  • Lebelo le phahameng la ho bala / ho ngola;
  • Mohloli o moholo oa ho ngola.

Chelete:

  • Litsenyehelo tse phahameng.

Lisele tsa Multi Level (MLC)

Mokhahlelong o latelang oa ntlafatso ea memori ea Flash ke mofuta oa MLC (o fetoletsoeng ka Serussia o utloahala joaloka "sele e maemong a mangata"). Ho fapana le SLC, ho sebelisoa lisele tse maemo a mabeli mona, tse bolokang likotoana tse peli tsa data. Lebelo la ho bala / ho ngola le lula le le holimo, empa mamello e fokotsehile haholo. Ho bua ka puo ea linomoro, mona lebelo la ho bala ke 25 ms, mme nomoro ea potoloho ea ho ngola hape ke 3'000. Mofuta ona o boetse o theko e tlaase, ka hona o sebelisoa lits'ebetsong tse matla haholo tsa mmuso.

Melemo:

  • Litšenyehelo tse tlase;
  • Lebelo le phahameng la ho bala / ho ngola ha le bapisoa le li-disk tsa kamehla.

Chelete:

  • Limakasine tse tlaase tse tlisoang.

Lisele tse tharo tsa boemo bo phahameng (TLC)

Mme qetellong, mofuta oa boraro oa memori ke TLC (mofuta oa Serussia oa lebitso la mofuta ona oa memori o utloahala joaloka "sele e mekha e meraro"). Mabapi le tse peli tse fetileng, mofuta ona oa theko e tlase 'me hajoale o fumanoa hangata lithetleng tsa likhakanyo.

Mofuta ona o na le letsoele le lengata, ho sele e ngoe le e ngoe 3 e bolokiloe mona. Ka lehlakoreng le leng, letsoalo le phahameng le fokotsa lebelo la ho bala / ho ngola le ho fokotsa mamello ea disk. Ho fapana le mefuta e meng ea mohopolo, lebelo mona le theohetse ho 75 ms, mme palo ea potoloho ea ho ngola hape e ea ho 1'000.

Melemo:

  • Boloka e phahameng ea data;
  • Litsenyehelo tse tlase

Chelete:

  • Palo e tlase ea potoloho ea ho ngola hape;
  • Lebelo le tlase / bala ho ngola.

Qeto

Ha re akaretsa taba, ho ka hlokomeloa hore mofuta o potlakileng le o tšoarellang oa memori ea Flash ke SLC. Leha ho le joalo, ka lebaka la theko e phahameng, mofuta ona oa memori o ile oa nkeloa sebaka ke mefuta e theko e tlase.

Budget, 'me ka nako e ts'oanang, e potlakile haholo ke mofuta oa TLC.

Mme qetellong, moelelo oa khauta ke mofuta oa MLC, o fanang ka lebelo le phahameng le ho ts'epahala ha o bapisoa le li-disk tsa tloaelehileng mme ha o theko e boima haholo ka nako e ts'oanang. Bakeng sa papiso e eketsehileng, bona tafole e ka tlase. Mona ke likarolo tsa mantlha tsa mefuta ea memori e sebelisitsoeng ho bapisa.
