Pasina kukanganisa: isu tinoedza yakanyanya kugadzirwa SSD Kingston KC2500

Iko kukurumidza kusimudzira kweSSD uye NAND memory controller tekinoroji inosungira vagadziri kuti vaenderane nekufambira mberi. Naizvozvo, Kingston akazivisa kuburitswa kweimwe itsva KC2500 SSD nekumhanya kwekuverenga kusvika ku3,5 GB/sec, uye kunyora kumhanya kusvika pa2,9 GB/sec.

Zvigadzirwa zvitsva zvinoratidzwa muhukuru huna kubva ku250 GB kusvika ku2 TB uye zvose zvinogadzirwa muM.2 2280 fomu factor, yakagadzirwa nePCI Express 3.0 x4 yekubatanidza interface neNVMe 1.3 protocol uye inotsigira kupera-ku-kuguma. kuchengetedza data uchishandisa 256-bit AES hardware encryption. Encryption inoshanda munharaunda yemakambani, yakapihwa rutsigiro rweTCG Opal 2.0 uye Microsoft eDrive. Kumhanya hunhu kunoenderana nehukuru hweiyo SSD:

• 250 GB - kuverenga kusvika ku3500 MB / s, nyora kusvika ku1200 MB / s;
• 500 GB - kuverenga kusvika ku3500 MB / s, nyora kusvika ku2900 MB / s;
• 1 TB - kuverenga kusvika ku3500 MB/s, nyora kusvika ku2900 MB/s;
• 2 TB - kuverenga kusvika ku3500 MB/s, nyora kusvika ku2900 MB/s.

Iyo yakataurwa waranti nguva ndeye 5 makore.



Mwoyo wechero NVMe drive ndiye controller uye Kingston anoenderera mberi nekushandisa inozivikanwa Silicon Motion SM2262ENG processor. Sezvineiwo, ese 8 chiteshi anowanikwa kune controller anoshandiswa. Uye musiyano mukuru kubva kuKC2000 ndiyo yakagadziridzwa firmware, iyo inokutendera iwe kushandisa ese NAND memory reserves. Uye, mumashoko angu pachangu, overclocked NAND memory chips.

Iyo package inosanganisira iyo SSD KC 2500 pachayo uye kiyi yekumisikidza iyo Acronis Yechokwadi Mufananidzo HD utility. Nerubatsiro rwayo, zvichave nyore kutamira kune dhiraivha nyowani nekugadzira mufananidzo wedhiraivha yako yekare. Kudhiraivha kwakagadzirwa mune yakajairika M.2 2280 fomu factor uye inokodzera kuiswa mumaPC nemalaptops. Yakajairika fomati muWindows inosiya 931 gigabytes yemahara nzvimbo yemushandisi. Iyo dhizaini yeNAND ndangariro yakapetwa kaviri, uye iyo SSD pachayo inokutendera iwe kuti uise kumwe kutonhora pairi, asi sezvazvinozoitika gare gare, hachisi chinhu chinodiwa.

Test Methodology

Iyo topology yechimiro cheSSD madhiraivha inosanganisira kushandiswa kwekunyora uye kuverenga buffer, pamwe neakawanda-tambo. DRAM cache saizi inowanzove yakamira kana yakasimba. Mumazuva ano maSSD, vatongi veSilicon Motion vanowanzove ne "inonyengera" ine simba DRAM cache yakaiswa, uye inodzorwa neiyo firmware. Hunyengeri hukuru huri mu controller uye firmware. Iyo iri nani uye inofambira mberi iyo controller uye adaptive firmware inoshandiswa kune akasiyana siyana ekushandisa, iyo inokurumidza iyo SSD inoshanda, chero yakakwira-kumhanya NAND ndangariro iripo.

Bhenji rekuyedza raisanganisira Intel chikuva ine ASUS ROG Maximus XI Hero mamaboard (Wi-Fi), Intel Core i7 9900K processor, ASUS Radeon RX 5700 vhidhiyo kadhi, 16 GB yeDDR4-4000 ndangariro uye Windows 10 X64 inoshanda sisitimu. (kuvaka 19041).

Mhedzisiro yebvunzo

• Advanced kuverenga nekunyora bvunzo
• Miedzo yebasa ine akasiyana block saizi, pamwe nekumhanya chaiko pane 16 GB faira.

PCMark 10 Kuchengeta

• Quick System Drive Benchmark: muyedzo mupfupi unoteedzera kuremerwa kwakareruka pane yekuchengetedza sisitimu. Maseti ekuedzwa anoshandiswa anodzokorora zviito chaizvo zvehurongwa uye zvirongwa zvine drive;
• Data Drive Benchmark: inodzokorora mutoro pane yekuchengetedza sisitimu muchimiro chebvunzo seti yeNAS (kuchengetedza uye kushandisa mafaera emhando dzakasiyana).

Kupisa panguva yekuteedzera kurekodha

Iyo yakajairwa yekurekodha maitiro paKC2500 SSD inokutendera iwe kuti uongorore dhigirii rekudziya kwemudziyo pasina kutonhora kunoshanda. Iwe haungashamiswe kana tikakuudza kuti kupisa ndiro ibwe rekona repamusoro-kuita SSDs. Mainjiniya ari kunetsekana nedambudziko iri uye kuyedza kusaisa iyo SSD mumamodhi akaomarara. Iyo yakapusa nzira inosanganisira kuisa radiator (yakatengwa yakaparadzana, kana kushandisa mamaboard yekutonhora sisitimu), kana kuunza modhi yekusvetuka kunyora mitsetse yekuburitsa mutongi. Muchiitiko ichi, kushanda kunoderera, asi SSD haina kupisa. Iyo imwecheteyo chirongwa chinoshanda pane processors pavanenge vasvetuka mavhiri kana vanyanya kupisa. Asi kana iri processor, mapundu haazooneki kune mushandisi senge SSD. Mushure mezvose, nekupisa pamusoro petembiricha yakaiswa nevagadziri, iyo SSD inosvetuka yakawandisa kutenderera. Uye izvi zvinozoita kuti "kuoma" muhurongwa hwekushanda. Neraki, muKingston KC2500 iyo firmware inogadziriswa kuitira kuti panguva yekurekodha mutongi anozorora kana DRAM cache yapera. Kune chero basa rekurekodha, iyo buffer inotanga kubuda, controller inoburitswa, ipapo iyo data inodzokera mubuffer uye kurekodha kunoenderera nekumhanya kumwechete pasina kumira kwenguva refu. Iyo tembiricha ye72C iri padhuze nekunetsa, asi bvunzo pachayo yakaitika mumamiriro ezvinhu asina kunaka: iyo SSD yaive padyo nekadhi revhidhiyo uye yakashaya mamaboard heatsink. Kuisa radiator inouya nebhodhi reamai kwakatibvumira kudzikisa tembiricha kusvika pa53-55C. Iyo SSD sticker haina kubviswa, uye iyo yekupisa padhi yebhodhi reamai yakashandiswa sechinhu chinopisa kupisa. Uye zvakare, saizi yeASUS ROG Maximus XI Gamba radiator haina kukura zvakanyanya, uye saka ine chete avhareji yekupisa kupisa kushanda. Zvakakodzera kufunga kuti nekuisa iyo Kingston KC2500 pane yakaparadzana PCIe adapta bhodhi uye nekuishongedza neradiator, unogona kukanganwa zvachose nezve tembiricha mamiriro.

Dynamic cache

Nechinyakare, chero ongororo yekutyaira inosanganisira DRAM cache yakazara bvunzo inoteverwa nechiziviso chehukuru hwayo, asi ichi chirevo chenhema. Muenzaniso Kingston KC2500 iyo inokurumidza buffer inogovaniswa zvine simba kwete chete muzana yenzvimbo yemahara, asi zvakare zvichienderana nerudzi rwe data riri kunyorwa.

Semuenzaniso, ngatiedzei kuzadza dhisiki yese nefaira ine data isina kurongeka. Iyi faira ine compressible uye isina-compressible data mumabhuraki akasiyana. Nedzidziso, buffer inokurumidza inofanira kukwana 100-200 GB, asi sezvauri kuona, mhedzisiro yaive yakasiyana. Kudonha kwakakosha mukurekodha kwemutsara kwakaonekwa chete pa400+ GB mamaki, iyo inotitaurira nezve yakaoma yekurekodha kutonga algorithm yeiyo firmware. Panguva ino, zvinova pachena kuti maawa emurume akaenda kupi mukugadzira iyo KC2500. Nekudaro, iyo SLC cache paKC2500 drive ine simba rekugovera uye zvinoenderana nezvakawanda zvinhu, asi zvirokwazvo haina kugumira ku150-160 GB.

Mhando dzekuwana SSD OS Windows 10

Chikanganiso chechipiri chakajairika ndechekusatendera muverengi kuti anzwisise kuti chii chinopinda mudhisiki kana ukaishandisa sedhisiki system. Pano zvakare, nzira yakarurama yekuongorora inokosha. Ini ndichaedza kudzokorora basa rakajairwa musystem yekushandisa semushandisi. Kuti tiite izvi, tinodzima chimwe chinhu kumarara, kuvhura gumi nemaviri mafaera mu Photoshop, panguva imwe chete mhanyisa dhisiki yekuchenesa, kutumira kunze kubva kuExcel, tanga tavhura matafura akati wandei, uye ramba uchinyora chinyorwa ichi. Kufanana kuisirwa zvigadziriso hakuna kukwana, asi ndizvozvo, ngatimhanyei zvigadziriso kubva kuSteam.

Munenge maminetsi e10 ebasa, zvinopfuura 90% zvezvikumbiro zvaive nechokuita nekuverenga mafaira mu4K blocks, uye inenge hafu yekunyora mumabhuroki akafanana. Ini ndinoona kuti iyo paging faira muWindows nharaunda yaive pakufunga kweiyo system. Pakazara, mufananidzo unoratidza kuti haisi kukurumidza kukurumidza iyo yakakosha kubasa, asi kuti inguva yekupindura yezvidiki-block mashandiro. Uyezve, huwandu hwema operation aya hauna kukura zvakanyanya. Sezvingatarisirwa, iwe unofanirwa kufunga nezve kutenga inokurumidza SSD yemitambo (kurodha mitambo pachayo uye nekumhanya kwekunyora zvinyorwa zvakakoshawo). Uye sechimwe chinyorwa, zvakanaka kuwana yakakwira mutsara wekuverenga / kunyora kumhanya kana zvasvika pakugara kukopa kana kunyora kwedata.

zvakawanikwa

Kingston KC2500 kuenderera mberi kweiyo yakakurumbira KC2000 nhevedzano, pane yakakurumidza ndangariro ine firmware yakagadziridzwa kumakomputa edesktop. Kuvandudzwa kwacho kwakakanganisa kumhanya kwekuverenga nekunyora kwemitsara. Maitiro eiyo SLC cache yakagadziridzwa; ine mamwe madhigirii erusununguko uye kugadzirisa kune akasiyana mamiriro. Sebhonasi, Kingston anoenderera mberi nekupa vatengi vane makore mashanu waranti, pamwe nerutsigiro rwe5-bit XTS-AES encryption.
