Aia kekahi poʻe makemake e hoʻohana i nā ʻāpana kiʻekiʻe mai ka ʻāpana ʻoihana i ko lākou ola i kēlā me kēia lā. Makemake lākou e hōʻoia ʻaʻole e make koke kā lākou SSD ma muli o ka nele o ka mana a i ʻole i ka hoʻoiho ʻana i nā kahawai 4K nui i kēlā me kēia lā ma kahi ʻāpana NTFS ʻāpana me a i ʻole ma ka hui hou ʻana o Gentoo mai ke kumu.
ʻOiaʻiʻo, ʻaʻole hiki ke hoʻokō ʻia kēlā mau makaʻu i ka hoʻomaʻamaʻa, akā maikaʻi loa ke hoʻohana ʻana i kahi SSD me ka Power Loss Protection (, , ), nona kahi kumu hoʻopaʻa leo palena ʻole. A i ka wā e liʻiliʻi ai kona hiki no nā hana o kēia manawa, hiki ke hoʻohana ʻia ma ke ʻano he flash drive a i ʻole he disk hou, hāʻawi ʻia i makana a kūʻai ʻia paha.
Hāʻawi kēia ʻatikala i kahi papa inoa o nā SSD ʻoihana me ka mana o 1.92TB, i hāʻule i kēia manawa i ke kumukūʻai i ke kiʻekiʻe o nā SSD mea kūʻai aku (< $300), akā loaʻa kahi kumu kākau o 2 Petabytes a ʻoi aku paha.
No laila, mahalo i ka hāʻule ʻana o nā kumukūʻai SSD, hiki iā mākou ke hoʻokomo i nā monsters server multi-terabyte i nā PC home a me nā kamepiula.
ʻAʻole i hoʻomohala ʻia ka interface SATA III no ka manawa lōʻihi, no laila ua hoʻokuʻu ʻia nā SSD no ka hoʻohana ʻana i nā ʻoihana i nā makahiki i hala aku nei i kūpono no ka hoʻomaikaʻi ʻana i nā kamepiula a i ʻole nā papapihi me kahi interface SATA, akā ua hāʻule nui ko lākou kumukūʻai.
Manaʻo wau i kēia nui ~ 2TB i mea maikaʻi loa i ka wā e hoʻonui ai i kahi ʻōnaehana kahiko:
- ʻO kēia ka nui loa i kākoʻo ʻia e MBR. No laila, inā ʻaʻole kākoʻo kāu BIOS iā UEFI, a laila ʻo kāu koho kēia. Hoʻomoʻa ʻoe i kāu subsystem disk i ke kaupaku (mea nui no nā laptops me hoʻokahi disk).
- He 512 bytes ka nui o kēia mau disks, hiki iā lākou ke hoʻohana me kekahi polokalamu. ʻOiai me Windows XP.
Ma kahi o ka waiwai hoʻopaʻa leo nui, ʻokoʻa nā hui SATA SSDs:
- Palekana meaʻai. Inā pau ka mana, hāʻawi nā capacitor tantalum (emi pinepine i ka ceramic) i ka SATA SSD me ka ikaika e kākau i ka cache i ʻole e hāʻule ka ʻōnaehana faila.
- Paʻa o nā ʻano māmā. Hoʻohana pinepine nā mea kūʻai aku i ka cache SLC, a laila hiki ke hāʻule nui ka wikiwiki.
- Hoʻokaʻawale nā mea hana i nā ʻāpana hoʻomanaʻo flash ma ka maikaʻi. Hoʻokomo ʻia nā mea maikaʻi loa i nā SSD hui.
- I kekahi manawa hoʻohana ʻia ka hoʻomanaʻo MLC ma kahi o TLC haʻahaʻa, 3D-NAND TLC, QLC.
No laila, eia kahi papa o nā hiʻohiʻona SSD hui kūʻai (a hiki i $300) 2TB. Ua nānā au i nā kumukūʻai ma nā kūʻai kūʻai pūnaewele a me nā pūnaewele e like me Avito. Akā hiki ke kūʻai ʻia kekahi mau disc mai ka papa inoa ma nā hale kūʻai maʻamau no ~ 25% keu. ʻO ke kiʻekiʻe o kahi disk i ka papaʻaina, ʻoi aku ka maikaʻi o ke kūʻai ʻana.
Aia kēia papa ʻaina i nā SSD ʻaʻole wale me MLC, inā ʻaʻole he 2 mau laina i koe.

I mea e hoʻomaopopo ai i nā wikiwiki e loaʻa iā mākou ma hope o ka hoʻomaikaʻi ʻana, e hāʻawi wau i kekahi mau screenshots mai CrystalDiskMark 6.0.2. Loaʻa ka nui o nā motherboards kahiko i kahi interface SATA III, no laila e hoʻohui wau i kekahi mau hopena i loaʻa ma SATA II a me SATA I.

ʻO kahi mea kupaianaha - ua kūleʻa loa ka mea hoʻokele SATA II a ua ʻoi aku ka maikaʻi o ka mana SATA III ma ka hoʻāʻo heluhelu heluhelu a kākau ʻole hoʻokahi me kahi hohonu o 1.
ʻO ka hoihoi ka ʻokoʻa ma waena o ka hoʻokō ʻana o SATA I (ʻike ʻia i nā makuahine kahiko) a me SATA III.

ʻO 1.92TB SSD me kahi kumuwaiwai i ana ʻia i nā petabytes, ma ke kumukūʻai o nā SSD maʻamau e māʻona i nā paranoid data a kūpono hoʻi no ka hoʻomaikaʻi ʻana i nā kamepiula a me nā kamepiula desktop me kahi interface SATA.
P.S. Mahalo no ke kiʻi .
P.P.S. E ʻoluʻolu e hoʻouna i nā hewa āu i ʻike ai ma kahi leka pilikino. Hoʻonui au i kaʻu karma no kēia.
