Kingston UV400 480GB

IMG_3311

Kingston je stari igrač na polju SSD-a i njihove smo prve modele testirali još tamo "davne" 2009. godine. Nedavno su na tržište izbacili UV400 seriju koja zamjenjuje prošlogodišnju UV300 koja je prva njihova s TLC NAND memorijom. Riječ je o ulaznim serijama SSD-a, čija je najjača točka cijena, čime su idealni za sve koji žele zamijeniti tradicionalne tvrde diskove. UV400 dolazi u kapacitetima od 120 pa sve do 960 GB, a Marvellov kontroler i Toshibin TLC NAND omogućavaju linearne brzine čitanja i zapisa do 550/500 MB/s.

UV400 serija dolazi u dva tipa pakiranja, s instalacijskim kitom za prijenosnike i PC računala i bez njega. Naš je primjerak došao bez kita, u jednostavnom pakiranju namijenjenom visećim policama u dućanima. Kroz prozirnu plastiku vidimo i sam proizvod, a glavni marketinški "selling point" je kako je UV400 10x brži od tradicionalnog HDD-a čije se ploče rotiraju na 7200 rpm. Jasno je stoga kako Kingston ovdje cilja na one korisnike koji još nisu prešli s tradicionalnih diskova na SSD-e, pri čemu je glavni adut niska cijena koštanja koju omogućava TLC (triple level cell) NAND. Kingston na UV400 seriju daje trogodišnje ograničeno jamstvo, te besplatnu tehničku podršku. Za razliku od konkurencije, ne nudi se nikakav pomoćni softver uz ovaj SSD.

SSD dolazi u lijepo dizajniranom metalnom kućištu koje služi i kao pasivni hladnjak, a dimenzija je 100 x 69.9 x 7 mm (masa je 57 grama). Nama je na test stigao primjerak kapaciteta 480 GB koji po tvorničkim specifikacijama ima linearnu brzinu čitanja od 550 MB/s, a zapisa 500 MB/s. Nasumične 4K performanse su 90.000 IOPS-a za čitanje, te 35.000 IOPS-a za zapis. Kontroler je poznati Marvellov 88SS1074 koji ima četiri kanala (8 CE-a), podržava DEVSLP (device sleep) funkciju, ONFI/Toggle 2 (400 MT/s), NANedge error-correcting tehnologiju, LDCP (low-density parity check), 256-bitnu AES enkripciju podataka i SATA III sučelje, a napravljen je u 28 nm CMOS procesu. Prilagođen je za upotrebu s 15/16 nm MLC/TLC 3D NAND-om. TLC NAND memorija korištena u ovome disku je Toshibina, proizvedena u 15 nm proizvodnom procesu. Kao i neki drugi TLC diskovi i ovaj ima nešto SLC keš memorije koja služi za konzistentnije performanse zapisa, no nje nema puno pa se brzo desi pad brzine.

Vrlo bitan podatak kod TLC NAND-a je maksimalni broj zapisa, a koji je tipično niže nego kod SLC i MLC NAND-a. Kingston za 120 GB model navodi 50 TB, za 240 GB model 100 TB, za 480 GB model 200 TB i naposljetku za 960 GB model 400 TB, što su solidne vrijednosti. Disk jasno ima SATA III sučelje koje je kompatibilno i sa SATA II, ima radnu temperaturu od 0 do 70°C, i MTBF od 1 milijun sati. Potrošnja diska koju proizvođač navodi je oko 0.7 W u stanju mirovanja, oko 0.6 W u stanju čitanja, te oko 2.515 W u stanju zapisa. Disk podnosi maksimalne vibracije do 2.17 G u radu, te do 20 G kada ne radi.

Način testiranja

IMG_3315

Disk smo testirali na našoj standardnoj platformi (uz dodatak i Z170 platforme na kojoj smo ponovili nekoliko testova i rezultati su uvijek bili unutar statističke pogreške), a prilikom testiranja je disk radio s AHCI 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 sa 80% čitanja i 20% zapisa, Web Servera sa 100% čitanja i File Servera sa 80% čitanja i 20% zapisa, nakon čega ispisujemo broj izmjerenih IOPS-a. Napravili smo i testove transfera s diska na disk. 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.

Zaključak

IMG_3316

Kingston je sa UV400 uspješno zamijenio prethodnu seriju UV300 i donio kompetitivne performanse i dobru cijenu za svoju ulaznu seriju SSD-a. Kao što smo vidjeli UV400 se može nositi sa Trion 100/150 diskovima, zatim Transcend SSD370 te ADATA SP550, od kojih je u nekim slučajevima i dosta nadmoćniji - po pitanju IOPS performansi. UV400 pati od onoga od čega pati i svaki TLC SSD a to je pad performansi zapisa čim mu se popuni SLC priručna (keš) memorija.Uz to, kod zapisa većeg broja podataka mu se i kućište dosta zagrije, i premda termalni senzor pokazuje oko 47°C, na dodir je kućište dosta toplo. Još jedna zamjerka ide i na nedostatak softverske podrške, a to je nešto što konkurencija svakako ima. Generalno, UV400 ima sasvim respektabilne performanse, što su potvrdili i naši testovi transfera, te odlične miješane IOPS performanse u tri od četiri testa. Uz to, maksimalnih 200 TB zapisa zvuči sasvim solidno za TLC NAND memoriju (jedino Trion 150 ima nešto više). Na kraju, za cijenu od oko 850 - 950 kn za 480 GB prostora teško je ovome disku zamjeriti bilo što, jer je trenutno najjeftiniji na tržištu. Po najnižoj je cijeni nešto jeftiniji od generalno ipak sporijeg SP550 480 GB, te dosta jeftiniji od Triona 150 ili SSD370. UV400 će mnogima biti prvi SSD, koji će zamijeniti tradicionalni HDD bilo u prijenosniku ili stolnom računalu i svi oni će biti i više no zadovoljni.
