Ingabe i-SSD Caching iphumelela ngempela ekuthuthukiseni ukusebenza kwe-PC?
Isimo sombuso oqinile sinikeza ngokufinyelela kwedatha okusheshayo kakhulu futhi izikhathi zokulayisha. Inkinga yukuthi banikela isikhala esincane kakhulu sokugcina isitoreji futhi eze namanani amanani aphezulu kakhulu uma kuqhathaniswa nokushayela okunamandla. Amaseva wezinkampani zamabhizinisi asebenzise ukushayela kwe-state eqinile njengendlela yokugcina isikhala phakathi kwe-server kanye nemikhakha yabo ye-hard drive njengendlela yokukhulisa ukusebenza kokufinyelela kwedatha ngaphandle kwezindleko eziphezulu kakhulu ze-SSD ephelele. I-Intel ithumele lobuchwepheshe obufanayo kumakhompiyutha akhe amaningi eminyakeni eminingi edlule ne-chipset ye-Z68 ngesimo se-Smart Response Technology. Lesi sihloko sibheka ubuchwepheshe, ukuthi singayilungisa kanjani nokuthi kungabe kunezinzuzo ezingokoqobo zokuzisebenzisa ukuze kusize ukuthuthukisa ukusebenza komshini jikelele.
Ukusetha kwe-Smart Response Technology
Ukusebenzisa i-Smart Response Technology nge-compel esebenzayo yama-computer asekelwe kalula. Konke okudingekile ngempela kuyinkimbinkimbi yedrayivu, ukushayela kombuso oqinile, umshayeli we-Intel nokuhlelwa okukodwa ku-BIOS izinhlelo. Isinyathelo esiyinkimbinkimbi kunazo zonke ku-setting ye-BIOS. Okuyisisekelo, isilungiselelo se-BIOS se-controller hard drive sidinga ukusethwa ku-RAID setting kunendlela ye-ACHI. Bheka imibhalo yakho yebhodi le-motherboard ukuthi ungafinyelela kanjani i-BIOS ukuze wenze ushintsho.
Uma isistimu yokusebenza ifakiwe kwi-hard drive futhi ilayishwe umshayeli we-Intel Rapid Storage Technology, sekuyisikhathi sokusetha umshini wombuso oqinile. Fometha umbuso oqinile wesistimu ngesistimu yefayili ye-NTFS. Bese usungula uhlelo lwe-Rapid Storage Technology. Yiya kuthebhu ye-Accelerate bese ukhetha amandla. Kuzobe sekubuza ukuthi ngabe i-SSD engakanani kuya ku-64GB ofuna ukuyisebenzisa ukuze usebenzise i-cache nokuthi iyiphi imodi (exoxwa ngezansi ngezansi) ukuyisebenzisa. Uma lokho sekuqedile, i-cache isethaphu futhi kufanele isebenze.
Kuqinisiwe futhi kuphakanyisiwe
Phakathi nenqubo yokusetha, i-cache ingasethwa kwimodi ethuthukisiwe noma ephakanyisiwe. Lokhu kuzothinta ukusebenza kwe-cache ngendlela ukuthi ubhala ngayo idatha kwimoto. Imodi ethuthukisiwe isebenzisa indlela ebizwa ngokuthi ukubhala. Kulo modi, uma idatha ibhalwa ku-drive, ibhalelwe kokubili i-cache kanye ne-hard drive ngesikhathi esifanayo. Lokhu kugcina ukusebenza kubhala kudivayisi elula kakhulu yokubhala okuyinto ngokuvamile i-hard drive.
Imodi ephakanyisiwe isebenzisa uhlelo olubizwa ngokuthi ukubhala emuva. Kulesi simo, uma idatha ibhalwa ohlelweni, ibhalwa kwi-cache ngokushesha kuqala bese igcwaliswa ngokugcwele ku-hard drive drive. Lokhu kunikeza ukusebenza okubhaliwe okusheshayo kunokwenzeka kodwa kunenkinga eyodwa enkulu. Uma kwenzeka ukuhluleka kwamandla noma ukushayeka, kungenzeka ukuthi idatha izokonakaliswa ku-hard drive uma ingabhalwa ngokugcwele. Ngenxa yalokho, le medi ayinconywa nganoma yiluphi uhlobo lwesistimu yedatha ebucayi.
Ukusebenza
Ukuze ubone ukuthi i-Smart Response Technology entsha iphumelela kangakanani, ngisetha uhlelo lokuhlola nge-hardware elandelayo:
- Ibhodi lomama: ASRock Z68 Pro3
- Iprosesa: I- Intel Core i5-2500k (ukuhamba okuzenzakalelayo)
- Imemori: 8GB (2x4GB) G.SKILL Ripjaws DDR3 1600MHz
- Ukushayela Okubalulekile: I- WD Caviar Ebili SE16 640GB SATA ku-RAID 0
- I-State State Drive: I- OCZ Agility 3 60GB SATA III
Umehluko omkhulu ekusetheni kwami uma kuqhathaniswa nalokho abaningi abazoyisebenzisa ukusethwa kwe- RAID 0 . I-Smart Reponse Technology ingasebenzisa i-hard drive eyodwa noma isigaba se-RAID. Amashadi we-RAID aklanyelwe ukusebenza okuthuthukisiwe. Ukuhlolwa okuningi kobuchwepheshe kuze kube yimanje sekuye kwenziwa nge-drives eyodwa ngakho ngifuna ukubona ukuthi kuzokwenza yini ukuthuthukiswa kokusebenza ohlelweni oluvele lusebenzisa ubuchwepheshe obukhona ukuze kuthuthukiswe ukusebenza. Ukuze ubonise lokhu, ngenzansi ngithathe idatha ye-CrystalMark yokulinganisa nje nge-RAID:
- I-CrystalMark - I-WD Caviar amabili SE16 640GB ku-RAID 0
- Okulinganiselwe: 129.5 MB / s Funda, 164.8 MB / s Bhala
- 512k: 29.32 MB / s Funda, 64.84 MB / s Bhala
- 4k: .376 MB / s Funda, 1.901 MB / s Bhala
- 4k QD32: 1.598 MB / s Funda, 2.124 MB / s Bhala
Ngokulandelayo, ngigijimela ibhenkmark efanayo ku-OCZ Agility 3 60GB SSD ukuze uthole isisekelo salo sokusebenza:
- CrystalMark - OCZ Agility 3 60GB SSD
- Okulinganiselwe: 171.2 MB / s Funda, 75.25 MB / s Bhala
- 512k: 163.9 MB / s Funda, 75.5 MB / s Bhala
- 4k: 24.34 MB / s Funda, 57.5 MB / s Bhala
- 4k QD32: 48.39 MB / s Funda, 72.88 MB / s Bhala
Ekugcineni, nginike amandla i-caching nemodi ethuthukisiwe phakathi kwe-RAID 0 ne-SSD futhi igijima i-CrystalMark:
- I-CrystalMark - RAID 0 + I-Caching Caching
- Okulinganiselwe: 158.6 MB / s Funda, 74.18 MB / s Bhala
- 512k: 155.7 MB / s Funda, 62.08 MB / s Bhala
- 4k: 22.99 MB / s Funda, 1.981 MB / s Bhala
- 4k QD32: 78.54 MB / s Funda, 2.286 MB / s Bhala
Le miphumela ibonisa ukuthi ngokwemininingwane yedatha ibhala, uhlelo luyehliswa kancane kancane kumadivayisi amabili ngenxa yendlela yokubhala. Lokhu kunciphisa kakhulu idatha ebhaliwe ngokulandelana njengoba i-RAID 0 ihamba ngokushesha kune-SSD. Ngakolunye uhlangothi, ukufunda idatha kusuka ohlelweni okuyinhloso eyinhloko ye-caching ithuthukisiwe. Akuyona into ephawulekayo kwimininingwane elandelanayo kodwa kuyithuthuka enkulu uma kuziwa ekufundeni kwedatha engahleliwe.
Le ndlela yokuhlola isakhiwe kodwa. Ngakho ukuze ngithathe isinyathelo esengeziwe, ngiqedile imisebenzi embalwa ehlukile ohlelweni phezu kwamaphasethi amaningi ukuze ngibone ukuthi i-caching yenze kanjani ukusebenza kwayo. Nganquma ukubuka imisebenzi emine ehlukene ukubona ukuthi isilondolozi sithinte kanjani uhlelo. Okokuqala, ngenza i-boot ebandayo kwi-Windows 7 login screen kususa isikhathi se-hardware POST. Okwesibili, ngethumele uphawu lokubonisa ihluzo le-Unigine kusukela ekusungulweni kuze kuqalwe isiteji. Okwesithathu, ngihlolwe ukulayisha umdlalo olondoloziwe kusukela ku-Fallout 3 kusuka kusikrini sokulayisha ukuze ukwazi ukudlala. Ekugcineni, ngivivinye ukuvula izithombe ezingu-30 ngesikhathi esisodwa ku-Photoshop Elements. Ngezansi imiphumela:
- Isikhathi Sokugijima (I-Cold Boot / Unigine / Fallout 3 / Photoshop Elements)
- Ayikho i-SSD Cache: 28 sec / 40 sec / 13 sec / 19 sec
- Isilondolozi se-SSD - Phinda u-1: 23 sec / 35 sec / 13 sec / 19 sec
- Isilondolozi se-SSD - Phinda 2: 18 sec / 24 sec / 8 sec / 19 sec
- Isilondolozi se-SSD - Phinda 3: 16 sec / 24 sec / 7 sec / 18 sec
- Isilondolozi se-SSD - Phinda 4: 15 sec / 24 sec / 7 sec / 18 sec
Umphumela othakazelisayo kakhulu kulolu vivinyo i-Photoshop ayiboni inzuzo uma ulayisha ihluzo eziningi ohlelweni nesilondolozi uma kuqhathaniswa nokusethwa kwe-RAID standard. Lokhu kubonisa ukuthi akuzona zonke izinhlelo ezizobona izinzuzo ezivela ku-cache. Ngakolunye uhlangothi, ukulandelana kwe-boot ye-Windows kubonwe ukunciphisa cishe okungu-50% esilinganisweni sesikhathi esithathile ukungena ohlelweni njengoba kulayishe umdlalo wokulondoloza kusukela ekupheleni kwe-3. Isibhenikhi se-Unigine sabona ukunciphisa okuhle kwe-25% esikhathini sokulayisha kusuka ku-caching. Ngakho-ke, izinhlelo okufanele zilayishe idatha eminingi kusukela ku-drive zizobona izinzuzo.
Iziphetho
Ukushayela kombuso okuqinile kuphephe okuningi kakhulu kodwa kungakabi kubi kakhulu kune-hard drive uma udinga ukuba nokugcina okuningi. Ngokuba thoes ukwakha uhlelo olusha, kusengcono nakakhulu ukuthola SSD enhle njengoba drive primitive bese hard drive enkulu njengoba drive secondary. Lapho i-Intel's Smart Response Technology ewusizo kakhulu kubantu abanezinhlelo ezikhona ezingabheka ukuthuthukisa isivinini sabo sekhompyutheni ngaphandle kokubhekana nenkinga yokuvuselela ngokuphelele uhlelo lwabo lokusebenza noma ukuzama ukwenza inqubo ye-clone ukuhambisa idatha kusuka ku-hard drive ukuya i-SSD. Esikhundleni salokho, bangakwazi ukuchitha kancane kancane kwi-SSD encane bese beyibeka ohlelweni lwe-Intel olukhona olusekela i-Smart Response Technology futhi lunike amandla ekukhuliseni ukusebenza kwabo ngaphandle kokuhlukunyezwa okukhulu.
