Uphuhliso olukhawulezayo lwe-SSD kunye ne-NAND yetekhnoloji yokulawula imemori ibophelela abavelisi ukuba bahambisane nenkqubela phambili. Ke ngoko, uKingston wabhengeza ukukhutshwa kwentsha ngesantya sokufunda ukuya kuthi ga kwi-3,5 GB/sec, kwaye ubhale ngesantya ukuya kuthi ga kwi-2,9 GB/sec.
Iimveliso ezitsha zinikezelwa ngobukhulu obune ukusuka kwi-250 GB ukuya kwi-2 TB kwaye zonke zenziwe kwi-M.2 2280 yefom yefom, exhotywe nge-PCI Express 3.0 x4 yokudibanisa i-interface kunye ne-NVMe 1.3 protocol kunye nenkxaso ekupheleni ukukhuselwa kwedatha usebenzisa i-256-bit AES encryption ye-hardware. Uguqulelo oluntsonkothileyo luyasebenza kwimeko-bume yeshishini, ngokunikwa inkxaso ye-TCG Opal 2.0 kunye neMicrosoft eDrive. Iimpawu zesantya zixhomekeke kubungakanani be-SSD:
- I-250 GB - funda ukuya kwi-3500 MB / s, bhala ukuya kwi-1200 MB / s;
- I-500 GB - funda ukuya kwi-3500 MB / s, bhala ukuya kwi-2900 MB / s;
- I-TB eyi-1 - funda ukuya kwi-3500 MB / s, bhala ukuya kwi-2900 MB / s;
- I-2 TB - funda ukuya kwi-3500 MB / s, bhala ukuya kwi-2900 MB / s.
Ixesha lewaranti echaziweyo yiminyaka emi-5.
Undoqo wayo nayiphi na i-NVMe drive ngumlawuli kwaye i-Kingston iyaqhubeka nokusebenzisa i-processor eyaziwayo ye-Silicon Motion SM2262ENG. Ngokwemvelo, zonke iziteshi ezi-8 ezikhoyo kumlawuli zisetyenziswa. Kwaye umahluko omkhulu kwi-KC2000 yi-firmware ephuculweyo, ekuvumela ukuba usebenzise zonke iimemori ze-NAND zokugcina. Kwaye, ngamazwi am, ii-chips zememori ze-NAND ezigqithisiweyo.
Iphakheji ibandakanya i-SSD KC 2500 ngokwayo kunye nesitshixo sokuvula i-Acronis True Image HD utility. Ngoncedo lwayo, kuya kuba lula ukufudukela kwi-drive entsha ngokwenza umfanekiso wedrayivu yakho endala. I-drive yenzelwe kwifom ye-M.2 2280 eqhelekileyo kwaye ifanelekile ukufakwa kwiiPC kunye neelaptops. Ukufomatha okusemgangathweni kwiWindows kushiya i-931 gigabytes yendawo yasimahla kumsebenzisi. Uyilo lwememori ye-NAND lunamacala amabini, kwaye i-SSD ngokwayo ikuvumela ukuba ufake ukupholisa okongeziweyo kuyo, kodwa njengoko kuvela kamva, ayisiyomfuneko.
Uvavanyo Lwendlela
I-topology yesakhiwo se-SSD drives ibandakanya ukusetyenziswa kwe-buffer yokubhala nokufunda, kunye ne-multi-threading. Ubungakanani be-cache ye-DRAM iqhele ukuba yi-static okanye iguquguqukayo. Kwii-SSD eziqhelekileyo zanamhlanje, abalawuli beSilicon Motion bahlala benendawo βyobuqhetsebaβ eguquguqukayo ye-DRAM cache efakiweyo, kwaye ilawulwa yi-firmware. Iqhinga eliphambili lilele kumlawuli kunye ne-firmware. Umlawuli ongcono kunye nenkqubela phambili kunye ne-firmware eguquguqukayo isetyenziselwa iimeko ezahlukeneyo zokusetyenziswa, ngokukhawuleza i-SSD isebenza, ngaphandle kokuba imemori ye-NAND enesantya esiphezulu ikhona.
Ibhentshi yovavanyo yayiquka iqonga le-Intel eline-ASUS ROG Maximus XI Hero motherboard (Wi-Fi), i-Intel Core i7 9900K iprosesa, i-ASUS Radeon RX 5700 ikhadi levidiyo, i-16 GB yememori ye-DDR4-4000 kunye Windows 10 X64 inkqubo yokusebenza. (ukwakha i-19041).

PCMark 10 yokugcina
- I-Quick System Drive Benchmark: uvavanyo olufutshane olulinganisa umthwalo olula kwindlela yokugcina. Kusetyenziswa iiseti zovavanyo eziphinda-phinda ezona zenzo zenkqubo kunye neenkqubo nge-drive;
- I-Data Drive Benchmark: iphinda umthwalo kwisistim sokugcina ngendlela yeesethi zovavanyo lwe-NAS (ukugcina kunye nokusebenzisa iifayile zeentlobo ezahlukeneyo).
Ukufudumeza ngexesha lokurekhoda okulandelelanayo
Inkqubo yokurekhoda esemgangathweni kwi-KC2500 SSD ikuvumela ukuba uvavanye iqondo lokufudumeza isixhobo ngaphandle kokupholisa okusebenzayo. Awuyi kumangaliswa xa sikuxelela ukuba ukufudumeza ngundoqo we-SSDs yokusebenza okuphezulu. Iinjineli zilwa nale ngxaki kwaye zizama ukungafaki i-SSD kwiindlela ezinzima. Eyona ndlela ilula ibandakanya ukufaka i-radiator (ithengwe ngokwahlukileyo, okanye isebenzisa inkqubo yokupholisa ibhodi ye-motherboard), okanye ukwazisa imowudi yokutsiba imigca yokubhala ukukhulula umlawuli. Kule meko, ukusebenza kuyancipha, kodwa i-SSD ayigqithisi. Iskimu esifanayo sisebenza kwiiprosesa xa betsiba imijikelo xa beshushu kakhulu. Kodwa kwimeko yeprosesa, izikhewu aziyi kubonakala kumsebenzisi njenge-SSD. Emva kwayo yonke loo nto, ishushu ngaphezu kobushushu obusetwe ngabaqulunqi, i-SSD iya kutsiba imijikelo emininzi kakhulu. Kwaye oku kuya kubangela ukuba "imikhenkce" kwinkqubo yokusebenza. Ngethamsanqa, kwi-Kingston KC2500 i-firmware ilungelelaniswe ukuze ngexesha lokurekhoda umlawuli uphumle xa i-cache ye-DRAM iphelile. Kuwo nawuphi na umsebenzi wokurekhoda, i-buffer iqala ukuphuma, umlawuli ukhululiwe, emva koko idatha ibuyela kwi-buffer kwaye ukurekhoda kuqhubeka ngesantya esifanayo ngaphandle kokumisa ixesha elide. Ukushisa kwe-72C kusondele kakhulu, kodwa uvavanyo ngokwalo lwenzeka kwiimeko ezingathandekiyo: i-SSD yayifumaneka kufuphi nekhadi levidiyo kwaye yayingenayo i-heatsink ye-motherboard. Ukufakela iradiyetha eza kunye nebhodi yomama kwasivumela ukuba sinciphise ubushushu ukuya kwi-53-55C. Isitika se-SSD asizange sisuswe, kwaye i-thermal pad ye-motherboard yayisetyenziswe njengento eqhuba ukushisa. Ukongeza, ubungakanani be-ASUS ROG Maximus XI i-radiator ye-Hero ayinkulu kangako, kwaye ke ngoko inomsebenzi ophakathi wokuphelisa ubushushu. Kuyafaneleka ukuqwalasela ukuba ngokubeka i-Kingston KC2500 kwibhodi ye-adapter ye-PCIe eyahlukileyo kwaye uyixhobise nge-radiator, unokulibala ngokupheleleyo malunga neemeko zokushisa.
I-cache enamandla
Ngokwesiko, naluphi na uphononongo lokuqhuba lubandakanya uvavanyo olugcweleyo lwe-cache ye-DRAM elandelwa sisibhengezo sobungakanani bayo, kodwa le yingxelo yobuxoki ngokupheleleyo. Imodeli isithinteli esikhawulezayo sisasazwa ngokuguqukayo hayi kuphela njengepesenti yendawo ekhululekileyo, kodwa nangokusekwe kuhlobo lwedatha ebhaliweyo.
Umzekelo, makhe sizame ukugcwalisa idiski yonke ngefayile enedatha engacwangciswanga. Le fayile iqulethe idatha ecinezelekileyo kunye ne-non-compressible kwiibhloko ezahlukeneyo. Ngokwethiyori, i-buffer ekhawulezayo kufuneka yanele kwi-100-200 GB, kodwa njengoko ubona, isiphumo sahlukile. Ukuhla okuphawulekayo ekurekhodweni komgca kubonakala kuphela kuphawu lwe-400 + GB, olusixelela malunga ne-algorithm yokulawula ukurekhoda eyinkimbinkimbi ye-firmware. Ngeli xesha, kuyacaca apho iiyure zomntu zangena ekudaleni i-KC2500. Ke, i-cache ye-SLC kwi-KC2500 drive inolwabiwo oluguquguqukayo kwaye ixhomekeke kwizinto ezininzi, kodwa ngokuqinisekileyo ayiphelelanga kwi-150-160 GB.
Iintlobo zofikelelo kwi-SSD OS Windows 10
Impazamo yesibini eqhelekileyo ayivumeli umfundi ukuba aqonde ukuba yintoni ukufikelela okwenziwa kwidiski ukuba uyisebenzisa njengediski yenkqubo. Apha kwakhona, indlela echanekileyo yovavanyo ibalulekile. Ndiza kuzama ukuphinda umsebenzi oqhelekileyo kwinkqubo yokusebenza njengomsebenzisi. Ukwenza oku, siya kucima into kwidoti, sivule iifayile ezilishumi elinambini kwi-Photoshop, ngaxeshanye siqhube ukucocwa kwediski, ukuthumela ngaphandle kwi-Excel, siqale sivule iitafile ezininzi, kwaye siqhubeke nokubhala lo mbhalo. Ukufakwa okufanayo kohlaziyo akwanelanga, kodwa kulungile, masiqhube uhlaziyo oluvela kuSteam.
Phantse kwimizuzu ye-10 yomsebenzi, ngaphezu kwe-90% yezicelo zihambelana nokufunda iifayile kwiibhloko ze-4K, kwaye phantse isiqingatha sokubhala kwiibhloko ezifanayo. Ndiqaphela ukuba ifayile yokupheja kwindawo yeWindows ibikukubona kwenkqubo. Ngokubanzi, umfanekiso ubonisa ukuba akusiyo isantya esibaluleke kakhulu emsebenzini, kodwa kunoko ixesha lokuphendula kwimisebenzi yebhloko encinci. Ngaphezu koko, umthamo wale misebenzi awumkhulu kangako. Ngokwemvelo, kufuneka ucinge ngokuthenga i-SSD ekhawulezayo yemidlalo (ukulayisha imidlalo ngokwazo kunye nesantya sokubhala ukuhlaziywa kubalulekile). Kwaye njengelinye inqaku, kulungile ukufumana isantya sokufunda / sokubhala esiphakamileyo xa kuziwa ekukopeni rhoqo okanye ekubhalweni kwedatha.
ezifunyanisiweyo
kukuqhubela phambili kothotho lwe-KC2000 oludumileyo, kwimemori ekhawulezileyo ene-firmware elungiselelwe iikhompyuter zedesktop. Uphuculo luchaphazele isantya sokufunda nokubhala ngokulandelelana. Indlela ye-cache ye-SLC iye yahlaziywa; ineedigri ezininzi zenkululeko kunye nohlengahlengiso kwiimeko ezahlukeneyo. Njengebhonasi, i-Kingston iyaqhubeka nokubonelela abathengi ngewaranti yeminyaka emi-5, kunye nenkxaso ye-256-bit XTS-AES encryption.
Ngolwazi oluthe kratya malunga neemveliso zeKingston Technology, nceda undwendwele nkampani.
