Ke kūʻai aku nā mea kūʻai aku i nā huahana OPS, e ʻike lākou aia ʻelua ʻano o ka paʻakikī: SSD a me HDD. He aha ka SSD a me ka HDD? No ke aha ʻoi aku ka wikiwiki o SSD ma mua o HDD? He aha nā hemahema o SSD? Inā he mau nīnau kāu, e hoʻomau i ka heluhelu.

Hoʻokaʻawale ʻia nā pahu paʻakikī i nā mīkini paʻakikī (Hard Disk Drive, HDD) a me nā solid state drive (SSD).

ʻO ka mīkini paʻakikī ka diski kuʻuna a me ka maʻamau, i haku ʻia me: platter, magnetic head, platter shaft a me nā ʻāpana ʻē aʻe. E like me ka hana mechanical, ka

ʻO ka māmā holo kaʻa, ka helu o nā poʻo magnetic, a me ka nui o ka pā e hiki ke hoʻopili i ka hana. ʻO ka hoʻomaikaʻi ʻana i ka hana o nā diski paʻakikī HDD e hilinaʻi nui ʻia i ka hoʻonui ʻana i ka wikiwiki rotational, akā ʻo ka wikiwiki rotational kiʻekiʻe ke ʻano o ka piʻi ʻana o ka walaʻau a me ka hoʻohana mana. No laila, hoʻoholo ka hoʻolālā o HDD he paʻakikī ke hoʻololi i ka qualitatively, a ʻo nā kumu like ʻole e kaupalena i kāna hoʻonui.

ʻO SSD kahi ʻano mālama i puka mai i nā makahiki i hala iho nei, ʻo ka inoa piha ʻo ia ʻo Solid State Drive.

Loaʻa iā ia nā hiʻohiʻona o ka heluhelu wikiwiki a me ke kākau ʻana, ke kaumaha māmā, ka hoʻohana haʻahaʻa haʻahaʻa a me ka liʻiliʻi liʻiliʻi. No ka mea ʻaʻohe pilikia e hiki ʻole ke hoʻonui i ka wikiwiki o ka rotational, ʻoi aku ka maʻalahi o kāna hana ma mua o ka HDD. Me kona mau pono nui, ua lilo ia i mea nui o ka mākeke.

No ka laʻana, ʻo ka latency heluhelu maʻamau o kahi SSD he mau hapaʻumi wale nō o ka millisecond, ʻoiai ʻo ka latency heluhelu maʻamau o kahi HDD ma kahi o 7ms, a hiki paha ke kiʻekiʻe e like me 9ms.

ʻO ka wikiwiki o ka mālama ʻana i ka ʻikepili o HDD ma kahi o 120MB/S, aʻo ka wikiwiki o SSD o ka protocol SATA ma kahi o 500MB/S, a ʻo ka wikiwiki o SSD o ka protocol NVMe (PCIe 3.0 × 4) ma kahi o 3500MB/S.

I ka pili ʻana i nā noi kūpono, e pili ana i nā huahana OPS (mekini āpau āpau), hiki iā SSD a me HDD ke hoʻokō i nā pono mālama mālama. Inā ʻoe e ʻimi nei i ka wikiwiki a me ka hana ʻoi aku ka maikaʻi, pono ʻoe e koho SSD. A inā makemake ʻoe i kahi mīkini kālā, ʻoi aku ka maikaʻi o kahi HDD.

Ke helu nei ka honua holoʻokoʻa, a ʻo ka waihona waihona ka pōhaku kihi o ka mālama ʻikepili, no laila hiki ke noʻonoʻo ʻia ko lākou koʻikoʻi. Manaʻoʻia me ka hoʻomohalaʻana i kaʻenehana, eʻoi aku ka nui o nā huahana kiʻekiʻe a me nā kumu kūʻai e kūpono i nā pono. Inā he mau nīnau kāu e pili ana i ke koho ʻana i kahi ʻano kīkī paʻakikī, e ʻoluʻolu e kelepona mai iā mākou!

E hahai i kēia loulou no ka ʻike hou aku:
