Parizvino, Solid-State Drives kana SSD iri kuwana yakawanda uye yakakurumbira ( S. Olid. S. Tate. D. Rive). Izvi zvinokonzerwa nenyaya yekuti ivo vanokwanisa kupa zvese zvakaringana zvekuverenga kuverenga kuverenga-kunyora uye kuvimbika kwakanaka. Kusiyana nemagungano akaoma akaoma, hapana zvinhu zvinofamba zvinofamba pano, uye zvakakosha kupenya kwemusoro unoshandiswa kuchengeta data - Nand.
Panguva yekunyora chinyorwa, matatu marudzi emoremo ekuyeuka anoshandiswa: mlc, SLC uye tlc uye mune ino chinyorwa tichaedza kufunga kuti ndezvipi zviri nani uye kuti musiyano uripo pakati pavo.
Fananative ongororo yeSLC, MLC uye TLC Memory mhando
Nand Flash memory yakanyorwa zita rekuti mukukudzwa kweiyo yakakosha mhando ye data chiratidzo - kwete uye (zvine musoro kwete uye). Kana iwe usingaendi mune technical zvinyorwa, saka ngatitii Nand inoraira data mumabhuru madiki (kana mapeji) uye ndokubvumidza iwe kuti uwane yakakwira data kuverenga kuverenga.
Iye zvino ngatimboongororai kuti ndedzipi mhando dzekuyeuka dzinoshandiswa mudenga rakasimba-nyika.
SEGALE LELE Cell (SLC)
SLC ndeyemhando yekunyora yerangariro iyo inoshandisa single-level memery masero ekuchengetedza ruzivo (nenzira, Shanduro chaiyo muRussia Inonzwika se "sero-remugumi"). Ndokunge, imwe yedata yedata yakachengetwa muchitokisi chimwe chete. Sangano rakadaro rekuchengetedza rinobvumidzwa kupa yakanyanya kumhanya uye sosi huru yekunyorazve. Saka, kumhanya kwekuverenga kunosvika makumi maviri nemashanu ms, uye huwandu hwenguva dzekunyora ndezve 100'000. Nekudaro, kunyangwe ichinyararuka, SLC ndiyo mhando inodhura kwazvo yekuyeuka.Pros:
- Yakanyanya kuverenga-kunyora kumhanya;
- Big ROPLE KUSVIRA.
Mabhiza:
- Mutengo wakakwira.
Multi Level Cell (MLC)
Nhanho inotevera mukuvandudzwa kweiyo Flash ndangariro ndiyo mhando yeMLC (yakashandurwa muchiRussia chinonzwika se "mitezo-yakawanda-level cell"). Kusiyana neSLC, kune maviri-masero emasero anochengeta maviri e data mabheti. Iyo yekuverenga-kunyora kumhanya inosara pane yakakwirira chikamu, asi kutsungirira kunoderedza zvakanyanya. Kana iwe ukataura huwandu hwehuwandu hwehuwandu, ipapo kumhanya kwekuverenga ndi25 ms, uye huwandu hwenguva dzekunyorwa ndezve 3'000. Zvakare, iyi mhando ndeyese yakachipa, saka inoshandiswa mune yakawanda yakasimba-nyika drives.Pros:
- Mutengo wakaderera;
- Yakanyanya kuverenga-nyora kumhanya uchienzaniswa neunyanzvi discs.
Mabhiza:
- Nhamba yakaderera yekunyanyisa clecle.
Matatu Level Cell (TLC)
Pakupedzisira, rudzi rwechitatu rwevanhu ndangariro ndere (iyo Russian vhezheni yezita rerudzi urwu rwekurangarira rinonzwika se "zvitatu-tii cell"). Nezve vaviri vakapfuura, iyi mhando yakachipa uye inowanikwa kazhinji kazhinji muBhajeti Drives.Rudzi urwu rwakawanda runyararo, muchitokisi chimwe nechimwe pano 3 bits dzakachengetwa pano. Mukuvhunduka, yakakura density inotungamira kuderera mu kuverenga / kunyora kumhanya uye inoderedza kutsungirira kwe disc. Kusiyana nemamwe marudzi ekurangarira, kumhanya pano kwaderera kusvika makumi manomwe nemashanu, uye nhamba yekunyora cycle ndeye 100000.
Pros:
- Yakakura yekuchengetedza llensity;
- Mutengo wakaderera.
Mabhiza:
- Nhamba yakaderera yekunyanyisa matanda;
- Yakadzika kuverenga-kunyora kumhanya.
Mhedziso
Kupfupikisa kumusoro, kunogona kucherechedzwa kuti iyo yakanyanya kukwirisa uye inogara mhando yeiyo flash memory is slc. Nekudaro, nekuda kwemutengo wakakwira, ndangariro iyi yakaunganidza mhando dzinocheka.
Bhajeti, uye panguva imwe chete, kushoma yakakwira-kumhanya ndeye tlc mhando.
Uye pakupedzisira, iyo goridhe inoratidzika ndeyemhando yeMLC, iyo inopa kumhanya kwakanyanya uye kuvimbika kuenzaniswa neyakajairwa discs uye haina kudhura zvakanyanya. Kuti uwane kuenzanisa kunoonekwa, iwe unogona kuzvionera wega netafura pazasi. Iyo ine iyo ma parameter makuru emhando dzekuyeuka iyo fananidzo yakagadzirwa.
