Simudzira komputa yako ne1.92TB server SATA SSD ine rekodhi sosi ye2PB uye yepamusoro.

Kune vanhu vanofarira kushandisa zvemhando yepamusoro zvikamu kubva muchikamu chekambani muhupenyu hwavo hwemazuva ese. Ivo vanoda kuve nechokwadi chekuti SSD yavo haizoerekana yafa nekuda kwekutadza kwemagetsi kana nyora kuwedzera kana uchidhawunirodha hombe dze4K mazuva ese pane yakakamurwa NTFS chikamu ne 4K cluster size kana panguva yekutevera kuunganidzwa kweGentoo kubva kunobva.

Ehe, kutya kwakadaro hakuwanzo kuitika mukuita, asi zvakanaka kwazvo kushandisa SSD ine Simba Kurasikirwa Dziviriro (1, 2, 3), iyo ine inenge isina muganho wekurekodha sosi. Uye kunyange kana simba rayo rikava diki kumabasa emazuva ano, rinogona kushandiswa se flash drive kana sekuwedzera disk, yakapiwa sechipo kana kutengeswa.

Ichi chinyorwa chinopa runyoro rwebhizinesi SSDs ine huwandu hwe1.92TB, iyo ikozvino yadonha mumutengo kusvika pamwero wevatengi SSDs (< $300), asi iine chinyorwa chekunyora che2 Petabytes kana kupfuura.

Saka, nekuda kwekudonha kwazvino mumitengo yeSSD, tinogona kukwanisa kuisa akawanda-terabyte server monsters mumaPC epamba nemalaptops.

Iyo SATA III interface pachayo haina kugadzirwa kwenguva yakareba, saka maSSD akaburitswa kuti ashandiswe nemakambani makore akati wandei apfuura achiri akanyatsokodzera kusimudzira malaptop kana matafura ane SATA interface, asi mutengo wavo wakadzikira zvakanyanya.

Ini ndinoona saizi iyi ~ 2TB kuve yakakwana kana uchikwidzira sisitimu yekare:

1. Uhwu ndihwo saizi huru inotsigirwa neMBR. Naizvozvo, kana BIOS yako isingatsigire UEFI, saka iyi ndiyo sarudzo yako. Iwe unopomba yako disk subsystem kusvika padenga (yakakosha kumalaptops ane dhisiki rimwe chete).
2. Aya madhisiki ane saizi yechikamu che512 bytes, izvo zvinoita kuti vakwanise kushandisa chero software. Kunyangwe neWindows XP.

Pamusoro peiyo hombe yekurekodha sosi, makambani eSATA SSD anosiyana:

1. Dziviriro yezvokudya. Muchiitiko chekukundikana kwesimba, tantalum (kashoma kazhinji ceramic) capacitors inopa SATA SSD simba rakakwana rekunyora cache kuitira kuti faira yefaira irege kuparara.
   
2. Kugadzikana kwemaitiro ekumhanya. Zvishandiso zvevatengi zvinowanzo shandisa SLC cache, mushure mezvo kumhanya kunogona kudonha zvakanyanya.
3. Vagadziri vanoronga flash memory chips nemhando. Iwo akanakisa akaiswa mumakambani SSDs.
4. Dzimwe nguva MLC ndangariro inoshandiswa panzvimbo yekuchipa TLC, 3D-NAND TLC, QLC.

Saka, heino tafura inokwanisika (kusvika kumadhora mazana matatu) 300TB yemakambani SSD modhi. Ndakatarisa mitengo kunyanya pamaokisheni epamhepo uye masaiti akaita seAvito. Asi mamwe madhisiki kubva pakurongwa anogona kutengwa muzvitoro zvenguva dzose kwe ~ 2% zvimwe. Iyo yakakwirira dhisiki iri mutafura, iyo inowedzera purofiti inogona kutengwa.

Tafura iyi ine SSD kwete chete neMLC, zvikasadaro paizongosara mitsara miviri.

Kuti tinzwisise kuti ndezvipi zvinomhanya zvatichawana mushure mekusimudzira, ini ndichapa akati wandei skrini kubva kuCrystalDiskMark 6.0.2. Mazhinji mamabhodhi echikuru anoshaya SATA III interface, saka ini ndichawedzera mimwe mibairo inowanikwa paSATA II uye SATA I.

Chokwadi chinoshamisa - iyo SATA II controller yakabudirira zvekuti yakakunda iyo SATA III controller mune imwechete-shinda isina tambo kuverenga / kunyora bvunzo ine kudzika kwemutsara we1.

Chinonyanya kufadza ndicho musiyano pakati pekushanda kweSATA I (iyo ichiri kuwanikwa kune vanaamai vakwegura) uye SATA III.

Panguva ino kukunda kweSATA III kunowedzera kugutsikana. Nekudaro, nekuwana zvisina kujairika kune 1 shinda ine mutsara wakadzika we1, mutsauko haupfuuri 20%.

Nehurombo, handina kukwanisa kuwana ese maSDD kubva patafura iri pamusoro kuti ndiedzwe. Saka mufananidzo wekupedzisira:

zvakawanikwa

1.92TB SSD ine sosi yakayerwa mumapetabytes, pamutengo wetsika SSDs inogutsa chero data paranoid uye yakanakira kusimudzira malaptop uye desktop makomputa ane SATA interface.

PS Ndatenda nemufananidzo Triple Concept.
PPS Ndokumbira utumire chero kukanganisa kwaunoona mune yako meseji. Ini ndinowedzera karma yangu nekuda kweizvi.
