Ku cusboonaysii kombayuutarkaaga 1.92TB server SATA SSD oo leh kayd duubitaan oo ah 2PB iyo ka sareeya

Waxaa jira dad jecel inay isticmaalaan qaybo tayo sare leh oo ka socda qaybta shirkadda ee nolol maalmeedkooda. Waxay rabaan inay hubiyaan in SSD-goodu aanu si lama filaan ah u dhiman doonin koronto la'aan awgeed ama qor kordhin markaad soo dejisanayso durdurrada waaweyn ee 4K maalin kasta oo aad ku dhejiso qayb NTFS oo kala qaybsan oo leh Cabbirka kooxda 4K ama inta lagu guda jiro ururinta soo socota Gentoo ka il.

Dabcan, cabsida noocan oo kale ah marar dhif ah ayay ku dhacdaa ficil ahaan, laakiin aad bay u fiican tahay in la isticmaalo SSD oo leh Ilaalinta Awoodda Awoodda1, 2, 3), Kaas oo leh ku dhawaad ​​ilo duubid aan xadidneyn. Xitaa marka ay awooddiisu noqoto mid yar oo loogu talagalay hawlaha hadda jira, weli waxaa loo isticmaali karaa sida flash drive ama disk dheeraad ah, oo loo bixiyo hadiyad ama la iibiyo.

Maqaalkani waxa uu bixiyaa liiska ganacsiga SSD-yada oo leh awood 1.92TB ah, kuwaas oo hadda hoos ugu dhacay qiimaha macaamiisha SSDs (<$ 300), laakiin leh kheyraad qoraal ah oo ah 2 Petabytes ama ka badan.

Markaa, mahadsanid burburkii dhowaa ee qiimaha SSD, waxaan awood u yeelan karnaa inaan ku rakibno daanyeerrada server-ka terabyte-ka badan ee kumbiyuutarrada guriga iyo laptop-yada.

Isku xirka SATA III laftiisa lama horumarin muddo dheer, sidaa darteed SSD-yada loo sii daayay isticmaalka shirkadaha dhowr sano ka hor ayaa wali ku habboon kor u qaadida laptops ama miisasyada leh interface SATA, laakiin qiimahoodu aad ayuu hoos ugu dhacay.

Waxaan u arkaa cabbirkan ~ 2TB inuu yahay kan ugu wanaagsan marka la cusboonaysiinayo nidaam hore:

1. Tani waa cabbirka ugu badan ee MBR uu taageerayo. Sidaa darteed, haddii BIOS-kaagu aanu taageerin UEFI, markaa tani waa ikhtiyaarkaaga. Waxaad ku shubaysaa nidaamka hoose ee diskkaaga saqafka (muhiim u ah laptopsyada leh hal saxan).
2. Saxanadahani waxay leeyihiin cabbirka qaybta 512 bytes, taas oo ka dhigaysa inay suurtogal tahay in lagu isticmaalo software kasta. Xataa Windows XP.

Marka lagu daro kheyraadka duubista ee weyn, SATA SSD-yada shirkadu way ka duwan yihiin:

1. Ilaalinta nafaqeynta. Haddii ay dhacdo koronto la'aan, tantalum (in ka yar inta badan dhoobada) capacitors ayaa siinaya SATA SSD tamar ku filan si ay u qorto kaydka si nidaamka faylalka uusan u kala go'in.
   
2. Xasiloonida sifooyinka xawaaraha. Aaladaha macaamiisha ayaa inta badan isticmaala kaydka SLC, ka dib xawaaruhu si weyn ayuu hoos ugu dhici karaa.
3. Soo-saareyaashu waxay tayada ku kala soocaan chip-yada xusuusta flash-ka. Kuwa ugu fiican ayaa lagu rakibay SSD-yada shirkadaha.
4. Mararka qaarkood xusuusta MLC ayaa la isticmaalaa halkii TLC ka jaban, 3D-NAND TLC, QLC.

Markaa, waa kan miis la awoodi karo (ilaa $300) 2TB moodooyinka shirkadda ee SSD. Waxaan eegay qiimaha inta badan xaraashka onlaynka ah iyo goobaha sida Avito. Laakiin qaar ka mid ah saxanadaha liiska waxaa laga iibsan karaa dukaamada caadiga ah ~ 25% ka badan. Hadba inta uu saxanku ku jiro miiska sare ee faa'iidada badan ayaa la iibsan karaa.

Jadwalkani waxa uu ka kooban yahay SSD-yada oo keliya kuma koobna MLC, haddii kale waxa hadhay oo keliya 2 sadar.

Si loo fahmo xawaaraha aan heli doono ka dib cusboonaysiinta, waxaan bixin doonaa dhowr shaashadood oo laga soo qaaday CrystalDiskMark 6.0.2. Qaar badan oo ka mid ah Motherboard-yada qadiimka ah ayaa ka maqan interface SATA III, markaa waxaan ku dari doonaa natiijooyin laga helay SATA II iyo SATA I.

SATA II
Intel ICH10R SATA AHCI
SATA III
AMD SB7x0/SB8x0/SB9x0 SATA AHCI

Xaqiiqo cajiib ah - kontaroolaha SATA II aad buu u guulaystey oo wuxuu ka sare maray kantaroolaha SATA III imtixaan akhris/qoraal random-ka-salaysan oo qoto dheer oo saf ah 1.

Xiisaha ayaa ah farqiga u dhexeeya waxqabadka SATA I (kaas oo wali laga helayo hooyooyinka da'da weyn) iyo SATA III.

SATA I
Intel 82801GBM/GHM (ICH7-M Qoyska) SATA AHCI

Markan guusha SATA III waa mid lagu qanci karo. Si kastaba ha ahaatee, iyada oo la heli karo random 1 dun oo leh qoto dheer safka 1, faraqa kama badna 20%.

Nasiib darro, ma awoodin inaan ka helo dhammaan SSD-yada miiska sare si aan u tijaabiyo. Sidaa darteed sawirka ugu dambeeya:

natiijooyinka

1.92TB SSD oo leh kheyraad lagu cabiray petabytes, qiimaha SSD-yada caadadu waxay ku qancin doontaa xog kasta oo argagax leh waxayna ku fiican yihiin cusboonaysiinta laptops iyo kombuyuutarrada desktop-ka ee leh interface SATA.
