Chifukwa chiyani kuli bwino kugula 480G yolimba kuposa 240G?

Kuchepa mphamvuSSDchip ndi chip choipa?Mwachitsanzo, a128G SSDchip ndi bwino kuposa a120Gchip, a256gchip ndi bwino kuposa chipangizo cha 240G, ndi zina zotero, gimmick yotereyi yomwe imaponyedwa pamsika idzachititsa kuti pakhale kufunikira kwina.

Kukhoza kwakukuluSSDs ikhoza kukwaniritsa zosowa zathu zambiri zosungirako deta.Poyerekeza ndi ogwira ntchito muofesi, ogwiritsa ntchito kumapeto kwamasewera, kuchuluka kwakukulu kumatha kupereka magwiridwe antchito, onse owerengera ndi kulemba komanso kuthamanga kwa 4K mwachisawawa.

Kuchita ndi kukhala ndi moyo wautali ndizomwe zimayambira kufunikira

Komabe, zosowa zogula za wogwiritsa ntchito sizimangokhalira mphamvu, komanso pakuchita komanso moyo wautali.Kupanda mphamvu kumabweretsa mfundo yakutiSSDs omwe ali ndi mphamvu zochepa zomwe atsala ayenera kufafaniza deta yakale asanadzazidwe ndi deta yatsopano, koma ntchitoyi idzatenga nthawi ndikuchotsa deta kumachepetsanso moyo waSSDkamodzi.(Mwachitsanzo, ndalama zamsika zapano za TLC zitha kupirira kufufutidwa kwathunthu kwa disk 3K)

Chifukwa chake, boma lolimba lakhala likufunafuna mphamvu zambiri, ndi anthu ochepa okha omwe amalabadira chifukwa chomwe ma drive olimba ali ndi mphamvu ya Nth ya 2, monga.120G, 480g, 960 choncho. 

M'masiku akale Nand Flash idapangidwa ndi 2 bit pa cell, Flash cell imatha kusunga magawo awiri a data, ngakhale Nand Flash itapangidwa kukhala TLC kupita ku QLC, mphamvuyo ikadali mphamvu ya Nth ya 2.

Ndipo dziko lililonse lolimba lidzakhala ndi malo osungidwa a OP (Over-provisioning), kuphatikizapo malo oyambirira a OP omwe amapangidwa mwachibadwa ndi kutembenuka kwa binary ndi malo ena achiwiri a OP ngati pakufunika, gawo ili la OP danga lilipo mu SSD, silingathe. kuwerengedwa molunjika, kulembedwa ndi kupezeka ndi wogwiritsa ntchito.

Malo osungidwa a OP amagwiritsidwa ntchito kukhathamiritsa kulemba, kuchepetsa kukulitsa kulemba, kukonza moyo wolembera, ndi ntchito zina.Kutengera zosowa zogwiritsa ntchito, ogwiritsa ntchito amathanso kuwonjezera pawokha gawo lachitatu la malo a OP.

Kusiyanasiyana kwa Mtengo

Pakatikati pa hard-state drive imakhala ndi main control, flash memory ndi PCB.Kusiyana kokha pakati pa 240G ndi 120G pamsika ndi kuchuluka kwa kukumbukira kung'anima, koma pa mtengo, awiri 120G ndi 240G olimba boma poyerekeza ndi 240G adzakhala zochepa kuposa mtengo wa mpanda, PCB board ndi master control, koma Izi ndizomwe zili pamwamba, zenizeni kapena Nand Flash, zomwe zimawerengera 70-80% ya mtengo wamtengo wonse.SSD.

Ndi ndondomeko yamakono ya 64-wosanjikiza ya 3D, mphamvu ya kufa imodzi imatha kufika 256Gbit (32GB), kapena 512Gbit (64GB), kutanthauza kuti ndi ochepa okha omwe amafa omwe amafunikira mphamvu yofanana ya tinthu tating'onoting'ono.

Ndipo kuonetsetsa kuti pali okwanira kuchuluka kwa kung'anima kukumbukira kuti athe kuwerenga ndi kulemba nthawi yomweyo, ntchito ubwino njira bwino kuwerenga ndi kulemba ntchito, adzasankha bokosi n'zotsimikizira m'munsi mphamvu Die, chifukwa chake mphamvu yaing'onoMa SSDmusachepetse ndalama powonjezera mphamvu ya Die imodzi.

Kuchuluka kwakukulu kulibe mavutowa, mfundoyi ndi yofanana ndi gulu lathu la tsiku ndi tsiku la RAID, chifukwa chake mphamvu yaikuluSSDkuwerenga ndi kulemba ndikolimba.
