Popanda zolakwika: timayesa SSD yopambana kwambiri Kingston KC2500

Kukula mwachangu kwaukadaulo wa SSD ndi NAND memory controller kumapangitsa opanga kuti apitilize kupita patsogolo. Chifukwa chake, Kingston adalengeza kutulutsidwa kwatsopano SSD KC2500 ndi liwiro lowerenga mpaka 3,5 GB/sec, ndikulemba liwiro mpaka 2,9 GB/sec.

Zatsopanozi zimaperekedwa m'miyeso inayi kuchokera ku 250 GB mpaka 2 TB ndipo zonsezi zimapangidwa mu mawonekedwe a M.2 2280, okhala ndi PCI Express 3.0 x4 kugwirizana mawonekedwe ndi NVMe 1.3 protocol ndikuthandizira kumapeto mpaka kumapeto. chitetezo cha data pogwiritsa ntchito 256-bit AES encryption ya hardware. Kubisa kumagwira ntchito m'malo amakampani, chifukwa chothandizidwa ndi TCG Opal 2.0 ndi Microsoft eDrive. Makhalidwe othamanga amadalira kukula kwa SSD:

• 250 GB - werengani mpaka 3500 MB / s, lembani mpaka 1200 MB / s;
• 500 GB - werengani mpaka 3500 MB / s, lembani mpaka 2900 MB / s;
• 1 TB - werengani mpaka 3500 MB / s, lembani mpaka 2900 MB / s;
• 2 TB - werengani mpaka 3500 MB/s, lembani mpaka 2900 MB/s.

Nthawi ya chitsimikizo ndi zaka 5.



Pakatikati pagalimoto iliyonse ya NVMe ndiye wowongolera ndipo Kingston akupitiliza kugwiritsa ntchito purosesa yodziwika bwino ya Silicon Motion SM2262ENG. Mwachilengedwe, njira zonse 8 zopezeka kwa wowongolera zimagwiritsidwa ntchito. Ndipo kusiyana kwakukulu kuchokera ku KC2000 ndi firmware yabwino, yomwe imakupatsani mwayi wogwiritsa ntchito zosungira zonse za NAND. Ndipo, m'mawu anga omwe, tchipisi ta kukumbukira za NAND.

Phukusili limaphatikizapo SSD KC 2500 yokha ndi kiyi yoyambitsa Acronis True Image HD zofunikira. Ndi chithandizo chake, zidzakhala zosavuta kusamukira ku galimoto yatsopano popanga chithunzi cha galimoto yanu yakale. Kuyendetsa kumapangidwa mu mawonekedwe wamba a M.2 2280 ndipo ndikoyenera kuyika mu ma PC ndi laputopu. Kupanga kokhazikika mu Windows kumasiya ma gigabytes 931 a malo aulere kwa wogwiritsa ntchito. Kukonzekera kwa kukumbukira kwa NAND kuli mbali ziwiri, ndipo SSD yokha imakulolani kuti muyike kuziziritsa kwina, koma monga momwe zidzakhalire pambuyo pake, sichofunikira.

Njira yoyesera

Kapangidwe kake ka ma drive a SSD kumaphatikizapo kugwiritsa ntchito cholembera ndi kuwerenga, komanso kuyika ulusi wambiri. Kukula kwa cache ya DRAM nthawi zambiri kumakhala kokhazikika kapena kosinthika. M'ma SSD amakono, olamulira a Silicon Motion nthawi zambiri amakhala ndi "chinyengo" champhamvu cha DRAM choyika, ndipo chimayang'aniridwa ndi firmware. Chinyengo chachikulu chili mu controller ndi firmware. Kuwongolera bwino komanso kupita patsogolo kowongolera ndi firmware yosinthika imagwiritsidwa ntchito pazinthu zosiyanasiyana, SSD imagwira ntchito mwachangu, malinga ngati kukumbukira kothamanga kwa NAND kulipo.

Benchi yoyesera inali ndi nsanja ya Intel yokhala ndi bolodi ya ASUS ROG Maximus XI Hero (Wi-Fi), purosesa ya Intel Core i7 9900K, khadi ya kanema ya ASUS Radeon RX 5700, 16 GB ya kukumbukira kwa DDR4-4000 ndi Windows 10 X64 opareting'i sisitimu. (Kumanga 19041).

• Benchmark ya Data Drive: imabwereza zolemetsa pamakina osungiramo ngati ma seti oyesa a NAS (kusunga ndi kugwiritsa ntchito mafayilo amitundu yosiyanasiyana).

Kutentha panthawi yojambula motsatizana

Njira yojambulira yokhazikika pa KC2500 SSD imakupatsani mwayi wowunika kuchuluka kwa kutentha kwa chipangizocho popanda kuziziritsa mwachangu. Simungadabwe tikakuuzani kuti kutentha ndiye mwala wapangodya wa ma SSD ochita bwino kwambiri. Akatswiri akulimbana ndi vutoli ndikuyesera kuti asaike SSD m'njira zovuta. Njira yosavuta ndiyo kukhazikitsa radiator (yogulidwa padera, kapena kugwiritsa ntchito makina oziziritsa pa bolodi), kapena kuyambitsa njira yodumpha mizere yolembera kuti mutsitse wowongolera. Pankhaniyi, magwiridwe antchito amachepa, koma SSD siyimatenthedwa. Chiwembu chomwechi chimagwiranso ntchito pa mapurosesa akadumpha kuzungulira akatenthedwa. Koma pankhani ya purosesa, mipata sidzakhala yowonekera kwa wogwiritsa ntchito ngati SSD. Kupatula apo, atatenthedwa pamwamba pa kutentha kokhazikitsidwa ndi opanga, SSD idzalumpha mikombero yambiri. Ndipo izi zidzapangitsa "kuzizira" mumayendedwe opangira. Mwamwayi, mu Kingston KC2500 firmware imasinthidwa kuti panthawi yojambulira wolamulira apume pamene cache ya DRAM yatha. Pa ntchito iliyonse yojambulira, buffer imayamba kutha, wowongolera amatsitsidwa, kenako deta imabwereranso mu buffer ndikujambula kumapitilira liwiro lomwelo popanda kuyimitsidwa kwautali. Kutentha kwa 72C kuli pafupi ndi zovuta, koma kuyesedwa komweko kunachitika m'mikhalidwe yovuta: SSD inali pafupi ndi khadi la kanema ndipo inalibe heatsink ya motherboard. Kuyika rediyeta yomwe imabwera ndi bolodi la amayi kunatilola kuti tichepetse kutentha mpaka 53-55C. Chomata cha SSD sichinachotsedwe, ndipo pad yotentha ya boardboard idagwiritsidwa ntchito ngati zinthu zopangira kutentha. Kuonjezera apo, kukula kwa radiator ya ASUS ROG Maximus XI Hero si yaikulu kwambiri, choncho imakhala ndi kutentha kwapakati pa kutentha. Ndikoyenera kulingalira kuti poyika Kingston KC2500 pa bolodi yosiyana ya PCIe adaputala ndikuyipanga ndi radiator, mutha kuyiwala za kutentha.

Dynamic posungira

Pachikhalidwe, kuwunikira kulikonse kumaphatikizapo kuyesa kwa cache kwa DRAM kotsatiridwa ndi kulengeza kukula kwake, koma izi ndi zabodza. Chitsanzo Mphatso KC2500 buffer yofulumira imagawidwa mwachangu osati kuchuluka kwa malo aulere, komanso kutengera mtundu wa data yomwe ikulembedwa.

Mwachitsanzo, tiyeni tiyese kudzaza disk yonse ndi fayilo yokhala ndi deta yosasintha. Fayiloyi imakhala ndi data yokhazikika komanso yosakanizika m'mabulogu osiyanasiyana. Mwachidziwitso, buffer yofulumira iyenera kukhala yokwanira 100-200 GB, koma monga mukuwonera, zotsatira zake zinali zosiyana. Kutsika kwakukulu kwa kujambula kwa mzere kudawonekera kokha pa chizindikiro cha 400+ GB, chomwe chimatiuza za zovuta zojambulira zojambula za firmware. Pakadali pano, zikuwonekeratu komwe maola amunthu adapanga kupanga KC2500. Chifukwa chake, cache ya SLC pagalimoto ya KC2500 imakhala ndi gawo lamphamvu ndipo zimatengera zinthu zambiri, koma sizongokhala 150-160 GB.

Mitundu yofikira ku SSD OS Windows 10

Cholakwika chachiwiri chofala ndikusalola owerenga kuti amvetsetse zomwe zimaperekedwa ku diski ngati muzigwiritsa ntchito ngati disk. Apanso, njira yoyenera yowunika ndiyofunikira. Ndiyesera kubwereza ntchito yanthawi zonse pamakina ogwiritsira ntchito ngati wogwiritsa ntchito. Kuti tichite izi, tidzachotsa china chake ku zinyalala, kutsegula mafayilo khumi ndi awiri mu Photoshop, nthawi imodzi yoyeretsa disk, kutumiza kunja kuchokera ku Excel, titatsegula magome angapo, ndikupitiriza kulemba malembawo. Kukhazikitsa kofananirako sikukwanira, koma zili bwino, tiyeni tiyendetse zosintha kuchokera ku Steam.

Pafupifupi mphindi 10 za ntchito, zopempha zoposa 90% zinali zokhudzana ndi kuwerenga mafayilo mu midadada ya 4K, ndipo pafupifupi theka la zolemba zomwezo. Ndikuwona kuti fayilo yapaging m'malo a Windows inali pamalingaliro a dongosolo. Ponseponse, chithunzichi chikuwonetsa kuti sikuthamanga kwambiri komwe kuli kofunikira pantchito, koma nthawi yoyankha pazochita zazing'ono. Komanso, kuchuluka kwa ntchitozi sikuli kwakukulu. Mwachilengedwe, muyenera kuganizira zogula SSD yachangu yamasewera (kutsitsa masewerawo komanso kuthamanga kwa zosintha ndizofunikanso). Ndipo monga cholemba china, ndizabwino kuti muzitha kuwerenga / kulemba mwachangu kwambiri zikafika pakukopera kapena kulemba zambiri.

anapezazo

Mphatso KC2500 ndi kupitiriza kwa mndandanda wotchuka wa KC2000, pamtima wofulumira ndi firmware yosinthidwa pamakompyuta apakompyuta. Kusinthako kudakhudzanso liwiro la mzere wowerengera ndi kulemba. Njira yofikira ku cache ya SLC yasinthidwanso; ili ndi magawo ochulukirapo a ufulu ndi zosintha pazochitika zosiyanasiyana. Monga bonasi, Kingston akupitiliza kupatsa makasitomala chitsimikizo chazaka 5, komanso kuthandizira kwa 256-bit XTS-AES encryption.
