Nand memory
A drive aiki saboda da Nand memory: semiconductor kwakwalwan kwamfuta. A kwakwalwan kwamfuta na irin wannan memory, da farko, suna m, kuma abu na biyu - sosai capacious: idan a karo na farko cikin flash tafiyarwa da aka lossed ta saba Tantancewar woje a wancan lokaci, a yanzu Blu-ray fayafai suna ko wuce ta capacitance.

Duk da haka, Nand-memory yana daya hasara, a kwatanta da sauran iri ajiya na'urorin. Gaskiyar ita ce, da sabis rai daga wadannan kwakwalwan kwamfuta da aka iyakance ta da wani yawan overwriting hawan keke (Karanta / Rubuta-write matakai a Kwayoyin). A kan talakawan, da adadin KARANTA-Rubuta hawan keke ne 30,000 (dogara a kan irin memory guntu). Da alama cewa shi ne wuce yarda da yawa, amma a gaskiya shi ne kamar shekaru 5 m amfani. Duk da haka, ko da idan ƙuntatawa aka kai, da flash drive za a iya ci gaba da amfani, amma kawai don karanta data.
