Sinthani kompyuta yanu ndi seva ya 1.92TB SATA SSD yokhala ndi chojambulira cha 2PB ndi apamwamba

Pali anthu omwe amakonda kugwiritsa ntchito zida zapamwamba kwambiri zamagulu amakampani m'moyo wawo watsiku ndi tsiku. Akufuna kutsimikiza kuti SSD yawo sidzafa mwadzidzidzi chifukwa cha kulephera kwamagetsi kapena kulemba kukulitsa mukatsitsa mitsinje yayikulu ya 4K tsiku lililonse pagawo logawika la NTFS ndi 4K masango kukula kapena pakuphatikizanso kwa Gentoo kuchokera kugwero.

Zachidziwikire, mantha otere samachitika kawirikawiri, koma ndizabwino kwambiri kugwiritsa ntchito SSD yokhala ndi Chitetezo cha Kutayika Kwa Mphamvu (1, 2, 3), yomwe ili ndi zida zojambulira zopanda malire. Ndipo ngakhale mphamvu yake ikakhala yaying'ono pa ntchito zamakono, imatha kugwiritsidwa ntchito ngati flash drive kapena disk yowonjezera, yoperekedwa ngati mphatso kapena yogulitsidwa.

Nkhaniyi ikupereka mndandanda wa ma SSD ogwira ntchito omwe ali ndi mphamvu ya 1.92TB, yomwe tsopano yagwera pamtengo mpaka mlingo wa ogula SSD (< $ 300), koma khalani ndi zolemba za 2 Petabytes kapena zambiri.

Chifukwa chake, chifukwa cha kugwa kwaposachedwa kwamitengo ya SSD, titha kukwanitsa kukhazikitsa zimphona zamaseva a multi-terabyte m'ma PC apanyumba ndi laputopu.

Mawonekedwe a SATA III pawokha sanapangidwe kwa nthawi yayitali, kotero ma SSD omwe adatulutsidwa kuti agwiritsidwe ntchito zaka zingapo zapitazo akadali oyenerera kukweza ma laputopu kapena ma desktops okhala ndi mawonekedwe a SATA, koma mtengo wawo watsika kwambiri.

Ndikuwona kukula uku ~ 2TB kukhala koyenera pakukweza dongosolo lakale:

1. Uku ndiye kukula kwakukulu komwe MBR imathandizira. Chifukwa chake, ngati BIOS yanu siyigwirizana ndi UEFI, ndiye kuti iyi ndi njira yanu. Mumapopera gawo lanu la disk mpaka padenga (zofunikira pama laputopu okhala ndi diski imodzi).
2. Ma diskswa ali ndi kukula kwa gawo la 512 byte, zomwe zimawapangitsa kuti azigwiritsidwa ntchito ndi mapulogalamu aliwonse. Ngakhale ndi Windows XP.

Kuphatikiza pazojambula zazikulu, ma SATA SSD amasiyana:

1. Chitetezo cha zakudya. Kukanika mphamvu, tantalum (kawirikawiri ceramic) capacitors amapereka SATA SSD mphamvu zokwanira kulemba posungira kuti file dongosolo si kugwa.
   
2. Kukhazikika kwa mawonekedwe a liwiro. Zida za ogula nthawi zambiri zimagwiritsa ntchito cache ya SLC, pambuyo pake liwiro limatha kutsika kwambiri.
3. Opanga amasankha tchipisi tokumbukira kung'anima ndi khalidwe. Zabwino kwambiri zimayikidwa mu SSD zamakampani.
4. Nthawi zina kukumbukira kwa MLC kumagwiritsidwa ntchito m'malo mwa TLC yotsika mtengo, 3D-NAND TLC, QLC.

Chifukwa chake, nali tebulo lamitundu yotsika mtengo (mpaka $300) 2TB makampani SSD. Ndinayang'ana mitengo makamaka pa malonda pa intaneti ndi malo ngati Avito. Koma ma diski ena pamndandanda amatha kugulidwa m'masitolo wamba kwa ~ 25% zambiri. Kukwera kwa disk kuli patebulo, kupindula kwambiri kungagulidwe.

Gome ili lili ndi ma SSD osati ndi MLC okha, apo ayi pakanakhala mizere iwiri yokha.

Kuti timvetsetse zomwe tidzapeza pambuyo pa kukonzanso, ndipereka zithunzi zingapo kuchokera ku CrystalDiskMark 6.0.2. Ma board a amayi ambiri achikulire alibe mawonekedwe a SATA III, chifukwa chake ndiwonjezera zotsatira zopezeka pa SATA II ndi SATA I.

Chowonadi chodabwitsa - wowongolera wa SATA II adachita bwino kwambiri kotero kuti adapambana wowongolera wa SATA III pamayeso owerengera / kulemba opanda ulusi umodzi wokhala ndi mzere wakuzama wa 1.

Chochititsa chidwi ndi kusiyana pakati pa machitidwe a SATA I (omwe akupezekabe kwa amayi achikulire) ndi SATA III.

anapezazo

1.92TB SSD yokhala ndi gwero loyesedwa mu ma petabytes, pamtengo wa ma SSD achizolowezi amakwaniritsa zosokoneza zilizonse za data ndipo ndiabwino pakukweza ma laputopu ndi makompyuta apakompyuta okhala ndi mawonekedwe a SATA.

PS Zikomo chifukwa cha chithunzichi Triple Concept.
