SSD vs HDD: Ndi Chiyani Choyenera Kwa Inu?

Kodi pali kusiyana kotani Ssd ndi Hdd? Solid State Drives (SSDs) ndi Hard Disk Drives (HDDs) akhoza kugawana zofanana zakuthupi, koma njira zawo zosungira deta zimasiyana kwambiri. Mtundu uliwonse wagalimoto uli ndi zabwino ndi zovuta zake, ndipo kusankha kuti ndi iti yomwe ikuyenerani kutengera momwe mumagwiritsira ntchito kompyuta yanu. Upangiri wathu wa HDD vs. SSD umaphwanya magwiridwe antchito amtundu uliwonse wa drive drive ndi zomwe zimakukhudzirani.

Momwe ma HDD amagwirira ntchito:

Ma HDD ndi zida zovuta zosungirako zomwe zimakhala ndi mbale zomvera maginito, mkono wa actuator wokhala ndi mitu yowerengera/kulemba, ndi mota yozungulira mbale. Motsogozedwa ndi wowongolera wa I/O ndi firmware, ma drive awa amalinganiza deta pamayendedwe okhazikika ndi magawo. Kulemba ma aligorivimu kukonza deta musanasunge, kulola fimuweya kuzindikira ndi kukonza zolakwika. Kuthamanga kwa mbale yokonzedweratu, kuyambira 4200 mpaka 7200 rpm, kumapereka mphamvu zopezera deta ndi kulemba mu HDDs.

Kuwerenga/Kulemba:

Nthawi iliyonse mukamapempha kompyuta kuti itenge kapena kukonzanso deta, woyang'anira I / O amalangiza mkono wa actuator kumene deta ili, ndipo mitu yowerengera / kulemba imasonkhanitsa deta powerenga mtengo mu adiresi iliyonse. Ngati pempho likukhudza kukonzanso deta, mitu yowerengera / kulemba imasintha mtengo pamayendedwe okhudzidwa ndi gawo.

Zovuta:

Zida zamakina zomwe zimagwiritsidwa ntchito powerenga ndi kulemba deta mu HDDs zimatsogolera ku nthawi yayitali yobwezeretsa poyerekeza ndi njira zamagetsi. Ziwalo zamakina zimatha kuwonongeka ngati zasokonekera kapena kugwetsedwa, makamaka pa laputopu. Ma HDD nawonso ndi olemera ndipo amadya mphamvu zambiri poyerekeza ndi ma Solid State Drives (SSDs).

Ubwino wa HDDs:

Ma HDD ndiukadaulo woyesedwa-ndi-wowona, nthawi zambiri ndiokwera mtengo kuposa ma SSD osungira momwemo. Pakadali pano, ma HDD amapereka malo osungiramo okulirapo kuposa ma SSD.

Kodi SSD (Solid State Drive) ndi chiyani?

Momwe ma SSD amagwirira ntchito:

Ma SSD amagwiritsa ntchito kukumbukira kwa flash, makamaka ukadaulo wa NAND, pakuchita bwino komanso kukhazikika. Mosiyana ndi ma HDD, ma SSD alibe magawo osuntha, kukulitsa kulimba, kugwira ntchito pakutentha kotsika, komanso kugwiritsa ntchito mphamvu zochepa. Ntchito ya NAND imaphatikizapo kujambula ma transistors oyandama kuti asunge deta mumtundu wa block. Wowongolera wa SSD amatenga gawo lofunikira pakutsata malo a data.

Kuwerenga/Kulemba:

Kwa SSDs, kukonzanso deta kumakhala kovuta kwambiri. Gawo lililonse la block likasinthidwa, chipika chonsecho chiyenera kutsitsimutsidwa. Deta yochokera ku chipika chakale imakopera ku chipika chosiyana, chipikacho chimachotsedwa, ndipo deta imalembedwanso ndi kusintha kwa chipika chatsopano.

Nthawi zonse mukapempha kompyuta kuti itenge kapena kusinthira deta, wolamulira wa SSD amayang'ana adilesi yomwe yafunsidwa ndikuwerenga momwe akulipiritsa.

Munthawi yopanda ntchito, njira yomwe imatchedwa kusonkhanitsa zinyalala imatsimikizira kuti zomwe zili mu midadada yakale zafufutidwa ndikukonzekera kulembedwanso. Palinso njira yotchedwa kudula, kudziwitsa SSD ikhoza kudumpha kulembanso deta ina panthawi yofufuta. Izi ndizofunikira kuti mupewe kuvala msanga pagalimoto, chifukwa chipika chilichonse chimakhala ndi malire owerengera / kulemba.

Kuti muchepetse kuvala, algorithm imatsimikizira kuti chipika chilichonse mugalimoto chimadutsa njira zowerengera / kulemba. Njira iyi, yomwe imadziwika kuti kuvala leveling, imachitika zokha pomwe drive ikugwira ntchito.

Monga momwe kuwerenga / kulemba kumakhudzira kusuntha kwa data, ma SSD nthawi zambiri amakhala ndi malo osungira. Kuchuluka kwa galimotoyo sikunafotokozedwe ku makina ogwiritsira ntchito ndipo sikutheka kwa ogwiritsa ntchito. Izi zimapereka mpata woyendetsa galimoto kuti isamuke ndikuchotsa zinthu popanda kusokoneza mphamvu zonse zosungira.

Zovuta:

Ma SSD ndiukadaulo watsopano, chifukwa chake ndi okwera mtengo kuposa ma HDD. Ngakhale kukumana, kupeza mkulu-Mphamvu Ssds zitha kukhala zovuta kwambiri poyerekeza ndi ma HDD. Ma HDD amatha kupereka kuchulukitsa kwa 2.5 kuchuluka kwa ma SSD.

Ubwino wa SSDs:

Chifukwa chiyani musankhe Solid State Drive? Ma SSD amatha kufulumizitsa kuthamanga kwamasewera, mapulogalamu, ndi makanema. Chifukwa cha ukadaulo wogwiritsidwa ntchito, ma SSD ndi opepuka, amapirira bwino kusuntha ndi kugwa, ndipo amadya mphamvu zochepa, zomwe zimapangitsa kuti kutentha kwapang'onopang'ono kukhale kocheperako.

Chimodzi mwazabwino za SSD:

Ndi liwiro lawo lothamanga kwambiri poyerekeza ndi ma HDD. Mwachitsanzo, mndandanda wa G-BONG X, NVMe SSD yathu yothamanga kwambiri, imapereka liwiro lowerengera / kulemba mpaka 3400/3000MB/s. Ngakhale ma SSD onyamula amaposa ma HDD. Ndi liwiro lowerenga mpaka 1050MB/s ndi mphamvu mpaka 2TB, X8 imathamanga nthawi 100 kuposa ma drive a USB flash komanso nthawi 7.5 kuposa ma hard drive achikhalidwe.

Chisankho

Kusiyana pakati pa hard drive ndi hard state drive kuli muukadaulo womwe umagwiritsidwa ntchito kusunga ndi kubweza deta. Gome ili m’munsili likusonyeza zina mwazosiyana.

Ma HDD ndi otsika mtengo ndipo mutha kupeza malo ambiri osungira. Ma SSD, komabe, ndi othamanga kwambiri, opepuka, olimba, ndipo amagwiritsa ntchito mphamvu zochepa. Zofuna zanu zidzakuuzani kuti ndi galimoto iti yosungirako yomwe ingakuthandizireni bwino.
