Kingston KC2000 1TB

kingston_kc2000_1

KC2000 je Kingstonov flagship M.2 NVMe SSD predstavljen još tamo sredinom prošle godine. Konačno je sletio i u naš lab, i to u 1 TB izvedbi pa smo napokon mogli vidjeti što donosi nasljednik modela KC1000 koji smo testirali još 2017. godine. KC2000 donosi porast u kapacitetu pa je maksimum na 2 TB, za što je zaslužan gušći Toshibin 3D TLC nand. Kontroler je Silicon Motionov SM2262EN kojeg smo upoznali u Transcendovim i ADATA-inim uređajima. Uređaj dolazi u blister pakiranju i kartonskom omotu koji je namijenjen smještanju na police dućana sa štangicama. Ono najbitnije što saznajemo s pakiranja je podatak o 5-godišnjem jamstvu. Uz ovaj 1 TB model, dolaze još četiri izvedbe, a svaka od njih ima i drugačiju trajnost, tj. maksimalnu količinu zapisa u ćelije:
  • 250 GB model ima  izdržljivost 150 TBW (terabytes written)
  • 500 GB midel ima 300 TBW
  • 1 TB model ima 600 TBW
  • i 2 TB model 1.2 PBW (1.200 TBW)

KC2000 je NVMe PCIe x4 SSD u M2280 formatu. Ne dolazi s hladnjakom, koji je potrebno ili dodatno kupiti ili iskoristiti onaj koji dolazi s matičnom pločom. Prije malo više od dvije godine smo testirali njegovog prethodnika model KC1000 čiji je maksimalni kapacitet bio 960 GB. KC2000 je napravljen na crnom PCB-u dužine 80 milimetara, na kojem se nalazi 96-slojni 3D TLC NAND (BiCS4), dva DRAM čipa svaki kapaciteta 512 MB i Silicon Motionov SM2262EN kontroler. Prema tvorničkim podacima ima brzine čitanja i zapisa od 3,2 i 2,2 GB/s. Nasumične performanse su 350.000 IOPS-a za čitanje i 275.000 IOPS-a za zapis. Sa sigurnosne strane tu je AES 256, TCG Opal 2.0 i eDrive enkripcija.

SM2262EN je unaprijeđena verzija originalnog SM2262 kontrolera. Riječ je o kontroleru s PCIe 3.0 x4 sučeljem i podrškom za NVMe 1.3 protokol. Ima osam NAND kanala i četiri NAND Chip Enable linije. Brzina sučelja mu je 800 MT/s (megatransfera po sekundi). Podržava DDR4 DRAM širine sabirnice 32-bita ali i starije DDR3(L)/LPDDR3 širine 16-bita. Uz njega se na pločici terabajtnog modela nalaze i dva DRAM čipa svaki kapaciteta 512 MB (ukupno 1 GB). NAND čipovi su Toshibini, ima ih ukupno osam i svaki je kapaciteta 128 GB (1024 Gb), pa je ukupan kapacitet 1 TB (1024 GB). Tvornički podaci govore o potrošnji od 3 mW u stanju mirovanja, 2.1 W pri čitanju i 7 W pri zapisu.

Softver za nadzor rada je poznati Kingstonov SSD Manager malo zastarjelog ali funkcionalnog sučelja. Softver nudi mogućnost nadogradnje firmwarea, kada je dostupna nova verzija, pregled svih bitnih parametara rada diska, aktualne podatke o "zdravlju" diska, uključivanje sigurnosnih opcija kao što je TCG Opal i IEEE 1667, te Event log.

Način testiranja

kingston_kc2000_info

Disk smo testirali na novoj AMD-ovoj X570 platformi. Ploča je bila odlična ASRockova X570 Phantom Gaming X, procesor za Ryzen 9 3900X, memorija G.Skillova Trident Z Neo, a grafička kartica je bila referentna Radeon RX5700.Uređaj se pod velikim pasivnim hladnjakom ASRockove ploče nije pretjerano zagrijavao i najveća zabilježena temperatura nakon duge torture I/O Metrom je bila 49°C.

SSD je radio je u PCIe 3.0 x4 modu s NVMe driverima. Uz sve standardne testove koje provodimo tu je i simulacija četiriju situacija uz pomoć I/O Metera – Database sa 67% čitanja i 33% zapisa, Workstation s 80% čitanja i 20% zapisa, Web Servera sa 100% čitanja i File Servera s 80% čitanja i 20% zapisa, nakon čega ispisujemo broj izmjerenih IOPS-a. Savjeti za svakodnevnu operativu SSD-a pod Windows OS-om uključuju isključivanje stvari kao što su indeksiranje diska, zatim isključivanje prefetcha i Superfetcha te defragmentiranja koje je sasvim nepotrebno.

Na temelju izvršenih mjerenja performansi donosi rezultat u MB/s. PCMark10 je novi test koji koristimo, a radi na vrlo sličan način kao i PCMark8 samo s novijim stom Microsoftovih i Adobeovih alata. U testu vrtimo Full System Drive benchmark. U starijem benchmarku je KC2000 pri vrhu i jedino je Transcendov 220S brži za svakodnevnu upotrebu. Sljedeći disk koji koristi SM2262 kontroler je ADATA-in Gammix S11 koji je nešto sporiji, što je zasluga i manjeg kapaciteta. U novom PCMarku10 još nemamo usporedne rezultate.

AS SSD i CrystalDiskMark

I AS SSD i Cyrstal koriste nekompresibilne podatke, no mjerenja im se ponešto razlikuju pa ih koristimo oba za usporedbu. Sekvencijalne performanse čitanja su točno onakve kakve proizvođač navodi, pristupna vremena su niska, a i 4K performanse su vrlo dobre. ATTO Disk Benchmark

kingston_kc2000_atto_1 kingston_kc2000_atto_2

kingston_kc2000_atto_3

ATTO test smo izvrtili u tri scenarija. Prvi je bio standardan s fajlom veličine 2 GB, drugi s fajlom od 32 GB. Oba testa pokazuju odlične rezultate na cijelom području. Treći je test zanimljiv jer pokazuje IOPS performanse koje na 4K I/O size (najčešće mjereno) iznose oko 100K IOPS-a što je niže nego proizvođač obećava.

KC2000 pokazuje dobre i vrlo ujednačene performanse u svim testovima, a najbolje se snalazi u posljednjem testu koji izvršava 100% čitanja. Da je KC2000 brz u čitanju su nam pokazali i prethodni testovi, no dobar je i on u zapisu.

Zaključak

kingston_kc2000_4

Kingston KC2000 se pokazao kao iznimno brz disk u svim scenarijima, što se posebno odnosi na čitanje. Zapis je također vrlo dobar, no u čitanju se ističe što je pokazao i WebServer test napravljen u I/O Metru. Uz to, ispod solidnog pasivnog hladnjaka se ni ne zagrijava previše, pa je maksimalna zabilježena temperatura 49°C. Naravno, bez hladnjaka to raste i na preko 70°C, ali nitko M.2 SSD-e ne bi trebao koristiti ili bez hladnjaka ili bez dobre zračne struje preko njih. KC2000 u 1 TB izvedbi košta oko 1.700 kuna na domaćem tržištu i vrlo je konkurentan. Tko želi manje izvedbe platit će oko 500 kn za 250 GB, ili 900 kn za 500 GB izvedbu. Naravno, ne treba zaboraviti ni 2 TB izvedbu koja košta oko 3.600 kuna. Jednostavnom računicom dolazimo do toga da je upravo ova 1 TB izvedba najpovoljnija po gigabajtu prostora. Jamstvo je pet godišnje, maksimalno je na njega moguće zapisati do 600 TB podataka (600 punih diskova), a i sigurnosne su značajke odlične. KC2000 se zbog svega toga nameće kao odličan izbor.
