OCZ ARC 100 240GB test

OCZ ne miruje i predstavljanjem novog modela žele se vratiti punom snagom u tzv. value tržišni segment, tj. onaj u kojem kupci pomno biraju najjeftiniji proizvod koji ipak mora imati dobre performanse i kvalitetu. ARC 100 kombinira Barefoot 3 M10 kontroler s Toshibinim 19nm NAND-om, ne zakida kupca na ključnim tehnologijama a donosi prihvatljivu cijenu. Za 240GB model OCZ traži 119.99 USD, čime ulaze u domenu jeftinog Crucialovog MX100 modela kojeg smo nedavno testirali. Kakav je u odnosu na njega, ali i ostatak OCZ-ove ponude, provjerili smo u standardnoj "bateriji" testova u nastavku. No, najprije pogledajmo specifikacije.

S obzirom da je riječ o disku iz ulaznog segmenta, OCZ ne daje bundle kao kod skupljih modela. Tako tu nema 3.5" adaptera, ali ni Acronisovog softvera. Sve što dolazi uz disk koji je u blister pakiranju su upute za korištenje i instalaciju te informacije o jamstvu.

Kako sam OCZ kaže, kod ACR 100 serije, performanse susreću pristupačnost, pri čemu jamče dobru I/O konzistenciju koju osigurava Barefoot 3 M10 kontroler i Toshibin 19nnm NAND. Ova serija označava povratak OCZ-a u Value segment tržišta, koji im je jedini ostao nepokriven, nakon predstavljanja osvježenja za Mainstream, Enthusiast i Workstation segmente. Vertex 460, Vector 150 i RevoDrive 350 smo već testirali na PCEkspertu i tako nam ostaje ovaj novi ARC 100 kako  bi zaokružili njihovu ponudu.

Detaljne specifikacije uređaja ste mogli vidjeti na slajdovima iznad, a recimo samo kako OCZ uvodi tri modela 120GB, 240GB i 480GB. Najmanja verzija će imati preporučenu maloprodajnu cijenu od 74.99 USD, odnosno 0.63 USD/GB, dok će jače dvije koštati 119.99 i 239.99 USD, odnosno 0.5 USD/GB. Model kojeg danas testiramo ima deklarirane brzine čitanja i pisanja 480 MB/s  odnosno 430 MB/s. Maksimalni broj ulazno izlaznih operacija pri zapisu (4K QD32) je 75.000, a pri čitanju 80.000, uz Steady-State nasumični zapis od 18.000 IOPS-a. Disk ima 265-bitnu AES enkripciju, podržava BCH  ECC korekcije do 44 nasumična bita po 1KB, a podržava SMART tehnologiju. Korisnog prostora na disku formatiranom u NTFS ima 223.6GB. OCZ na disk daje jamstvo od tri godine uz maksimum od 20GB zapisa po danu.

Način testiranja

Disk smo testirali na Asusovoj Rampage IV Extreme ploči, i s Intelovim i7-3960X procesorom. Prilikom testiranja je radio u AHCI načinu rada i sa Microsoft Storage driverima (MSAHCI), što su mu dodijelili Windowsi 8.1. 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. 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.

OCZ je odigrao svog najjačeg aduta i provjerenu formulu iz Vertexa 460 i Vectora 150 prebacio u niži tržišni segment, te novu seriju nazvao ARC 100. Nikakvih tu nepoznanica nema. ARC 100 donosi respektabilne performanse, sa visokom i održivom razinom ulazno-izlaznih operacija koja nadmašuje ne samo konkurente kao što je Crucial MX100, nego i skuplje SSD-e. Novi SSD dolazi s izdržljivošću od 20GB/s u roku od tri godine (jamstvo), što bi trebalo biti dovoljno za veliku većinu korisnika, čak i onih koji će ga koristiti u profesionalne svrhe. Šećer na kraju su najavljene cijene. Najmanja verzija će imati preporučenu maloprodajnu cijenu od 74.99 USD (0.63 USD/GB), dok će 240 GB model koštati 119.99 USD a najveći 480 GB model 239.99 USD (oba 0.5 USD/GB). Kakve će cijene biti na našem tržištu tek treba vidjeti, no u uspjeh ARC 100 serije nimalo ne sumnjamo.
