SSD vs HDD: Ndeipi Yakakunakira Iwe?

Ndeipi misiyano pakati Ssd uye Hdd? Solid State Drives (SSDs) neHard Disk Drives (HDDs) inogona kugovera kufanana kwemuviri, asi nzira dzavo dzekuchengetedza data dzinosiyana zvakanyanya. Mhando yega yega yekutyaira ine zvayakanakira nezvayakaipira, uye kusarudza kuti ndeipi inokukodzera zvinoenderana nemashandisiro aunoita komputa yako. Yedu HDD vs. SSD gwara rinopwanya kushanda kwega yega yekuchengetedza mhando uye zvazvinoreva kwauri.

Mashandiro eHDDs:

HDDs midziyo yakaoma yekuchengetera inoumbwa nemagineti anonzwa ndiro, ruoko rwe actuator ine misoro yekuverenga / kunyora, uye mota yekutenderera kwendiro. Inotongwa neI/O controller uye firmware, aya madhiraivha anoronga data pane concentric tracks uye zvikamu. Kunyora algorithms process data usati wachengeta, ichibvumira firmware kuona uye kugadzirisa zvikanganiso. Iyo preset platter inomhanya, kubva pa4200 kusvika 7200 rpm, inoraira kugona kwekutora data uye maitiro ekunyora mumaHDD.

Kuverenga/Kunyora Maitiro:

Pese paunokumbira komputa kuti itore kana kugadzirisa data, iyo I / O controller inoraira ruoko rwe actuator iyo data iripo, uye misoro yekuverenga / yekunyora inounganidza data nekuverenga kubhadharisa mukero yega yega. Kana chikumbiro chinosanganisira kuvandudza data, iyo yekuverenga / kunyora misoro inoshandura mubhadharo pane yakakanganisika track uye chikamu.

Zvakaipa

Iwo ma mechanika ezvikamu anoshandiswa pakuverenga nekunyora data muHDD anotungamira kunguva refu yekudzosa zvichienzaniswa nemagetsi nzira. Mechanical parts anogona kukuvara kana akabatwa zvisina kunaka kana kudonha, kunyanya mumalaptop. MaHDD zvakarema uye anodya simba rakawanda zvichienzaniswa neSolid State Drives (SSDs).

Zvakanakira HDDs:

MaHDD akaedzwa-uye-echokwadi tekinoroji, kazhinji ane hupfumi kupfuura maSSD eiyo imwechete yekuchengetedza. Parizvino, maHDD anopa nzvimbo dzakakura dzekuchengetera kupfuura maSSD.

Chii chinonzi SSD (Solid State Drive)?

Mashandiro eSSDs:

MaSSD anoshandisa flash memory, kunyanya tekinoroji yeNAND, pakuita kwakasiyana uye kusimba. Kusiyana neHDDs, maSDD anoshaya zvikamu zvinofamba, kuwedzera kusimba, kushanda pane yakadzika tembiricha, uye kushandisa simba shoma. Iko kushanda kweNAND kunosanganisira anoyangarara-gedhi transistors kurekodha machaji kuchengetedza data mune grid-patterned block chimiro. Iyo SSD controller inoita basa rakakosha mukutevera nzvimbo dzedata.

Kuverenga/Kunyora Maitiro:

Kune SSDs, kuvandudza data kwakanyanya kuoma. Kana chero chikamu chebhuroka chikagadziridzwa, iyo block yese inofanira kuzorodzwa. Dhata kubva kubhuroka yekare inoteedzerwa kune imwe bhuroka, iyo block inodzimwa, uye data inonyorwazve neshanduko kubhuroka nyowani.

Pese paunokumbira komputa kuti itore kana kugadzirisa data, mutongi weSSD anotarisa kero yedata yakakumbirwa uye anoverenga mamiriro ekuchaja.

Munguva dzekusaita basa, maitiro anonzi kuunganidza marara anoita kuti ruzivo rwuri mumabhuroko ekare rwadzimwa uye rwakagadzirira kunyorwazve. Kune zvakare maitiro anonzi kudimbura, kuzivisa iyo SSD inogona kusvetuka kunyorazve imwe data panguva yekudzima block. Izvi zvakakosha kudzivirira kupera nguva isati yakwana padhiraivha, sezvo bhuroka rega rega rine nhamba inogumira yekuverenga / kunyora kutenderera.

Kuti uwedzere kudzikisira kupfeka, algorithm inovimbisa kuti yega yega mudhiraivha inowana yakaenzana nhamba yekuverenga / kunyora maitiro. Iyi nzira, inozivikanwa seyekupfeka chiyero, inoitika otomatiki sezvo dhiraivha inoshanda.

Sezvo maitiro ekuverenga / kunyora anosanganisira kufamba kwedata, maSSD anowanzo pamusoro-kugovera nzvimbo yekuchengetedza. Imwe huwandu hwedhiraivha haina kutaurwa kune inoshanda sisitimu uye haisvikike kune vashandisi. Izvi zvinopa nzvimbo yekuti dhiraivha ifambe nekudzima zvinhu pasina kukanganisa huwandu hwekuchengetedza.

Zvakaipa

SSDs tekinoroji nyowani, nekudaro inodhura kupfuura HDDs. Kunyangwe kubata, kuwana yakakwirira-Capacity Ssds inogona kunge yakanyanya kuoma kana ichienzaniswa neHDD. HDDs inogona kupa inosvika 2.5 nguva yekugona kweSSD.

Zvakanakira zveSSDs:

Sei uchisarudza Solid State Drive? MaSSD anogona kukurumidza kurodha kumhanya kwemitambo, maapplication, uye mafirimu. Nekuda kwetekinoroji inoshandiswa, maSDD akareruka, ari nani anomira kufamba uye kudonha, uye anopedza simba shoma, zvichikonzera kuderera kwekushisa kwekushanda.

Imwe yemabhenefiti akakosha eSSDs:

Kumhanya kwavo kwakanyanya kana zvichienzaniswa neHDDs. Semuenzaniso, G-BONG X yakatevedzana, yedu inokurumidza NVMe SSD, inopa inonakidza kuverenga/kunyora kumhanya kunosvika 3400/3000MB/s. Kunyangwe inotakurika SSDs inobuda HDDs. Iine kumhanya kwekuverenga kusvika ku1050MB/s uye kugona kusvika ku2TB, iyo X8 inokurumidza kakapetwa ka100 kupfuura USB flash drive uye 7.5 nguva nekukurumidza kupfuura echinyakare hard drive.

Chisarudzo

Musiyano uripo pakati pema hard drive uye solid state madhiraivha uri mune tekinoroji inoshandiswa kuchengeta nekutora data. Tafura iri pasi apa inoratidza mimwe misiyano.

HDDs dzakachipa uye unogona kuwana yakawanda yekuchengetedza nzvimbo. MaSSD, zvisinei, anokurumidza kukurumidza, akareruka, akasimba, uye anoshandisa simba shoma. Zvaunoda zvinozotaura kuti ndeipi dhiraivha yekuchengetedza ichashanda zvakanyanya kwauri.
