Yintoni iSolid-State Drive (SSD)?
Siyazi ukuba inkumbulo inokuba ziintlobo ezimbini- iyaguquguquka kwaye ayiguquguquki . I-SSD sisixhobo sokugcina esingaguqukiyo. Oku kuthetha ukuba idatha egcinwe kwi-SSD ihlala nasemva kokuba umbane umisiwe. Ngenxa yolwakhiwo lwazo (zenziwe sisilawuli seflash kunye ne-NAND flash memory chips), ii-slid-state drives zikwabizwa ngokuba zii-flash drives okanye iidiski eziqinileyo.
Ii-SSD - Imbali emfutshane
Iidiski ezinzima zazisetyenziswa ikakhulu njengezixhobo zokugcina iminyaka emininzi. Abantu basasebenza kwizixhobo ezinediski enzima. Ke, yintoni eyatyhalela abantu ukuba baphande ngesinye isixhobo sokugcina abantu abaninzi? Ii-SSD zenzeke njani? Makhe sithathe i-peek encinci kwimbali ukuze sazi inkuthazo emva kwee-SSD.
Ngeminyaka yoo-1950, bekukho ubuchwepheshe obu-2 obusetyenziswa ngokufanayo nendlela ii-SSD ezisebenza ngayo, ezizezi, imemori engundoqo yamagnetic kunye nevenkile yokufunda kuphela yekhadi-capacitor. Nangona kunjalo, zakhawuleza zaphela nya ngenxa yokufumaneka kweeyunithi zokugcina imigqomo ezingabizi kakhulu.
