Muaj peev xwm thiab Nqe
Muaj ob qhov laj thawj koj yuav xav yuav HDDs xyoo 2021. Muaj peev xwm, thiab tus nqi. Hard drives tseem pheej yig dua ib gigabyte dua SSDs. Thiab yog tias koj tab tom yuav cov HDDs nyoos, tsis muaj qhov zoo nkauj USB 3.0 enclosure thiab fais fab mov, lawv tseem pheej yig dua.
Piv txwv li, saib sai ntawm Amazon qhia tau tias koj tuaj yeem nqa 1TB SSD rau me ntsis tshaj $ 100. Qhov ntawd yog hom sab hauv, tsis yog hom portable nrog USB connector.
Rau qhov sib piv, 4TB HDD tuaj yeem muaj rau $ 60- $ 70. Thiab yog tias koj mus deb ntawm Amazon, koj tuaj yeem tau txais lawv txawm tias pheej yig dua.
Cov khoom siv-xeev tau zoo dua ntawm kev ceev, kev siv hluav taws xob, qhov loj me, thiab kav ntev. Ntawm qhov tod tes, lawv kim dua…
Qhov kawg. Yog hais tias koj xav tau ib tug loj tsav, hmoov zoo. Ib qho 8TB sab hauv SSD los ntawm Sabrent yuav raug nqi rau koj $ 1,500. Ib qho 8TB HDD tuaj yeem muaj rau tsawg li $ 200, lossis tsawg dua yog tias koj tsuas yog siv nws rau lub hom phiaj khaws cia.
Qhov teeb meem nrog HDDs yog tias lawv qeeb thiab nrov. Muaj spinning disks hauv, thiab lawv cov motors tsim suab nrov.

Xav txog cov ntaub ntawv yas, tsuas yog txoj kev nrawm dua, thiab nrog caj npab dhia thoob plaws qhov chaw, thiab koj muaj lub tswv yim dav.
Qhov ua kom yuam kev, yog li, yog siv ob qho tib si HDDs thiab SSDs, muab txhua qhov ua haujlwm qhov nws ua tau zoo.
"Nyob hauv tsev, peb yuav pom HDDs kom muaj lawv qhov chaw raug raws li daim duab, video, lossis cov ntaub ntawv khaws cia ntawm lub tshuab hauv zos, qhov ceev thiab kav ntev tsis tseem ceeb npaum li tus nqi qis thiab muaj peev xwm khaws cia txog 18TB ntawm cov ntaub ntawv ib disk, "hais tias Maksiuk.
Yog li, rau kev thaub qab, lossis rau txhua yam uas tsis xav tau nrawm, siv HDD. Thiab rau qhov ua tau zoo tshaj plaws, lossis ua haujlwm ntsiag to, siv lub xeev cov khoom siv disk.
