Ngaba i-SSD Caching iphumelele ngempela kwi-PC yokwenza umsebenzi?
I-drive ye-solid state inikezela ngokufikelela kwedatha ngokukhawuleza kunye namaxesha okulayisha. Ingxaki kukuba bahambisa indawo encinane yokugcina indawo kwaye bafika ngamanani amaninzi aphezulu xa kuthelekiswa nokuqhutshwa kanzima. Amaseva eklasi oshishino abasebenzisa imimoya eqinile njengendlela yokugcina umgca phakathi kwiseva kunye neendlela zabo zokuqhuba i-hard drive njengendlela yokwandisa ukusebenza kokufikelela kwedatha ngaphandle kweendleko eziphezulu kakhulu ze-SSD epheleleyo. I-Intel yazisa le teknoloji enye kwiikhomputha zayo ezininzi kwiminyaka emininzi edlulileyo kunye ne-chipset ye-Z68 ngendlela ye-Smart Response Technology. Eli nqaku likhangele iteknoloji, indlela yokuyibeka kunye nokuba ingaba zikhona iinzuzo ezibonakalayo zokusebenzisa oko kukunceda ukukhupha iikhomputha zentsebenzo jikelele.
Ukusekwa kweTeknoloji yeSempendulo ye-Smart
Ukusebenzisa i-Smart Response Technology ngeekhompyutheni ezisekelekileyo ze-Intel zilula kakhulu. Yonke into efunekayo yile idrayivu ekhuni, umqhubi wombuso oqinileyo, umqhubi we-Intel kunye nesimo esisodwa kwiindlela ze-BIOS. Isinyathelo esiyinkimbinkimbi kunokuba kusetyenziswe i-BIOS. Okubalulekileyo, isilungiselelo se-BIOS kumlawuli we-hard drive kufuneka simiselwe kwisilungiselelo se-RAID kunokuba i-ACHI imodi. Qhagamshelana neenkomfa zakho zebhodi ye-motherboard malunga nendlela yokufikelela kwi-BIOS ukwenza utshintsho.
Emva kokuba inkqubo yokusebenza ifakwe kwi-hard drive kwaye ilayishwe ngumqhubi we-Intel Rapid yeTheknoloji yeTeknoloji, lixesha lokumisa i-drive yommandla oqinileyo. Fometha i-state esebenzayo yokuqhuba ngefayile ye-NTFS. Emva koko uqalise inkqubo yeTeknoloji yeTeknoloji yokuLondoloza Yiya kwiKhawuleza yeTebhu kwaye khetha ukwenza. Kuya kukubuza ukuba uninzi kangakanani lwe-SSD ukuya kwi-64GB ofuna ukuyisebenzisa kwi-cache kwaye yintoni imodeli (exoxwa ngayo ngaphantsi) ukusebenzisa. Xa oko kwenziwa, i-cache isetyenziswe kwaye kufuneka isebenze.
Ukuphuculwa kunye nokuphakanyiswa
Ngethuba lokulungisa inkqubo, i-cache ingasetwa kwimodi ephakamileyo okanye ephakamileyo. Oku kuya kuphazamisa ukusebenza komcaka ngendlela ebhalwa ngayo idatha kwiimoto. Imodi ephuculweyo isebenzisa indlela ebizwa ngokuba yi-write-through. Kule ndlela, xa idatha ibhalwa kwi-drive, ibhalwa kwi-cache kunye ne-hard drive ngexesha elifanayo. Oku kugcina ukusebenza ukubhalela kwisicatshulwa sokubhala esicothayo ngokuqhelekileyo esiyi-hard drive.
Imodi ephakamileyo isebenzisa inkqubo ebizwa ngokuba yi-write back. Kule meko, xa idatha ibhalwa kwinkqubo, ibhalwa kwi-cache ngokukhawuleza kuqala kwaye emva koko izaliswe kwi-drive enokukhawuleza. Oku kunika ukubhala ngokukhawuleza kokusebenza kodwa kunenkinga enkulu enkulu. Xa kwenzeka ukungaphumeleli kwamandla okanye ukuphazamiseka, kungenzeka ukuba idatha iya kubonakaliswa kwi-drive enzima xa ingazange ibhalwe ngokugcwele. Ngenxa yoko, le meko ayikhuthazwa nayiphi na inkqubo yeenkcukacha ezibalulekileyo.
Ukusebenza
Ukuze ubone indlela esebenzayo ngayo iTeknoloji entsha yokuphendula kwe-Smart, ndimisela inkqubo yokuvavanya nge-hardware elandelayo:
- I-Motherboard: ASRock Z68 Pro3
- Inkqubo: Intel Core i5-2500k (isantya esizenzekelayo )
- Imemori: 8GB (2x4GB) G.SKILL Ripjaws DDR3 1600MHz
- Iimoto ezinzima: ezimbini ze- WD Caviar SE16 640GB SATA kwi-RAID 0
- I-State State Drive: I- OCZ Ubuchule 3 60GB SATA III
Ukwahluka okukhulu kwindlela yam yokumisela kuqhathaniswa nabaninzi abaya kusebenzisa ukusethwa kwe- RAID 0 . I-Smart Reponse Technology ingasebenza kunye ne-hard drive okanye i-RAID. Iimpawu ze-RAID zenzelwe ukuphucula ukusebenza. Uninzi lweemvavanyo zeteknoloji kuze kube yimanje zenziwe ngeenjini ezilodwa ukuze ndifune ukubona ukuba kuya kunika amandla ekusebenzeni kwinkqubo esele isebenzise iteknoloji ekhoyo ukwenzela ukukhulisa ukusebenza. Ukubonisa oku, ngezantsi ndithatha idatha ye-CrystalMark yeefayile ze-RAID kuphela:
- CrystalMark - I-WD Caviar ye-SE16 640GB kwi-RAID 0
- Ukulingana: 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
Emva koko, ndagqwesa ibhonkmark efanayo kwi-OCZ Agility 3 60GB SSD ukuze ufumane umgangatho waso wokusebenza:
- CrystalMark - OCZ Agility 3 60GB SSD
- Ukulingana: 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
Ekugqibeleni, ndenza i-caching ngemodi ephuculweyo phakathi kwe-RAID 0 kunye ne-SSD kwaye iqhume i-CrystalMark:
- CrystalMark - RAID 0 + SSD Caching
- Ukulingana: 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
Ezi ziphumo zibonisa ukuba ngokwemigqaliselo yedatha kubhala, inkqubo iyancipha ukuya kwizinto ezicothayo kwezixhobo zombini ngenxa yeendlela zokubhala. Oku kunciphisa kakhulu idatha ebhaliwe ngokulandelanayo njengoko i-RAID 0 ihamba ngokukhawuleza kune-SSD. Ngakolunye uhlangothi, ukufundwa kwedatha esuka kwinkqubo eyona nto injongo ephambili yokugcina i-caching iye yaphuculwa. Akunakwenzeka ngendlela ephawulekayo kwidatha elandelelanayo kodwa kukuphucuka okukhulu xa kuziwa kwiidatha ezingafundwayo.
Le ndlela yokuvavanya idibeneyo. Ngoko ukuthabatha inyathelo elongezelelweyo, ndaqeda imisebenzi embalwa eyahlukileyo kwinkqubo kwiipasiti ezininzi ukujonga indlela yokugcina i-caching yenze ngcono ngayo ukusebenza kwayo. Ndagqiba kwelokuba ndikhangele imisebenzi emine eyahlukileyo ukuze ndibone indlela i-cache echaphazele ngayo inkqubo. Okokuqala, ndenza ibhoot ebandayo kwi-Windows 7 yokungena kwesikrini kucima ixesha le-POST hardware. Okwesibini, ndiqalise i-Unigine benchmark benchmark ukususela kuze kuqalwe isilinganiselo. Okwesithathu, ndavavanya ukulayisha umdlalo ogcinwe ukusuka kwi-Fallout 3 ukusuka kwisikrini somthwalo ukuze ukwazi ukudlala. Ekugqibeleni, ndavavanya ukuvula iifoto ezingama-30 kanyekanye kwi-Photoshop Elements. Ngezantsi ziphumo:
- Isikhathi sokuqalisa (iCold Boot / Unigine / Fallout 3 / Photoshop Elements)
- Ayikho i-SSD Cache: 28 sec / 40 sec / 13 sec / 19 sec
- Isilondolozi se-SSD - Phinda 1: 23 sec / 35 sec / 13 sec / 19 sec
- I-SSD Cache - Phinda 2: 18 sec / 24 sec / 8 sec / 19 sec
- Isilondolozi se-SSD - Phinda 3: 16 sec / 24 sec / 7 sec sec / 18 sec
- Isilondolozi se-SSD - Phinda 4: 15 sec / 24 sec / 7 sec / 18 sec
Umphumo osishukumisayo kunolu vavanyo yi-Photoshop ayiboni nzuzo xa ulayisha imifanekiso emininzi kwiprogram kunye ne-cache xa kuthelekiswa nokusekwa kwe-RAID esemgangathweni. Oku kubonisa ukuba akuyiyo yonke inkqubo eya kubona inzuzo kwi-cache. Ngakolunye uhlangothi, ulandelelwano lwe-boot lweWindows lubone ukunciphisa ama-50% kwixesha elithathiweyo ukuba lingene kwinkqubo njengoko liye lalayisha umdlalo wokugcina ukusuka kwi-Fallout 3. Isilinganiselo sokulinganisa safumanisa nokunciphisa ama-25% ngexesha lokulayisha kwi-caching. Ngaloo ndlela, iiprogram ezimele zilayishe idatha eninzi kwi-drive ziya kubona izibonelelo.
Izigqibo
Izixhobo zombuso eziqinileyo ziye zitshiza ezininzi kakhulu ezinokuthengwa kodwa zihlala zibiza kakhulu kuneyona drive enzima xa kufuneka ube nokugcinwa okuninzi. Ukuba i-thoes yakha inkqubo entsha, kusenokuba luncedo nakakhulu ukufumana i-SSD enhle njenge-drive yokuqala kunye ne-hard drive enkulu njenge-drive yesibili. Lapho i-Intel's Smart Response Technology ibaluleke kakhulu kunabantu abaneenkqubo ezikhoyo eziza kubheka ukukhulisa isivinini sekhompyutheni ngaphandle kokuba bahambe ngokukhawuleza ukuvuselela kwakhona inkqubo yabo yokusebenza okanye bazame ukwenza inkqubo yeenkampani ukuhambisa idatha kwi-drive drive SSD. Kunoko, banokuchitha ixesha elincinci kwi-SSD encinci kwaye bayiphononise kwinkqubo ye-Intel ekhoyo exhasa i-Smart Response Technology kwaye inika amandla ekuphuculeni ukusebenza kwayo ngaphandle kwenkunkuma enkulu.
