Corsair Force LX 256GB

Corsair trenutno ima četiri linije SSD-a u prodaji - Force LX/LS/GT/GS i Neutron GTX. Mi smo na test dobili jedan iz Force LX serije kapaciteta 256GB. Riječ je o njihovom ulaznom proizvodu, koji je namijenjen zamjeni klasičnih tvrdih diskova po prihvatljivoj cijeni. Force LX serija broji tri modela kapaciteta 128, 265 i 512GB, a kontroler je Silicon Motionov SM2246. Silicon Motion je tvrtka osnovana još 1995. godine u San Joseu u Kaliforniji, ali im je trenutno sjedište na Tajvanu. Force LX dolazi u klasičnoj kartonskoj kutiji, pakiranje kakvo koristi većina proizvođača SSD-a, a unutar nje je disk još zaštićen u plastični omot.

Disk dolazi u niskom, 7 mm profilu, dok su ostale dimenzije klasične, dok je masa samo 50 grama. Razlog ovako laganom disku je aluminijsko kućište, te samo pola PCB-a u njemu, kao što se vidi na slikama ispod. Force LX podržava SATA III (6Gbps) sučelje, tipična potrošnja pod opterećenjem mu je 3W, a u stanju mirovanja oko 0.6W, radi na naponu od 5V. U stanju je podnijeti stres od 40G, a proizvođač na njega daje 3 godine jamstva. Korisnog prostora nakon formatiranja u NTFS je 238.5GB.

Otvaranjem kućišta uočavamo zašto je SSD toliko lagan (50 grama) - zato što je u njemu zapravo pola SSD-a. Naravno, nema smisla stavljati pločicu pune dužine, ako je sve stane na pola. S jeden se strane nalazi Silicon Motionov SM2246 kontroler, 256 GB Nanyine DDR3-1600 memorije, te četiri MLC ONFI NAND čipa svaki kapaciteta 32GB. Na stražnjoj strani pločice se nalazi još toliko čipova pa dolazimo do ukupnog kapaciteta SSD-a od 256GB.

Sillicon Motionov kontroler dolazi u TFBGA288 pakiranju te radi na naponu od 3.3V. Riječ je o modernom, četverokanalnom kontroleru, koji podržava 256-bitnu AES enkripciju, te TCG OPAL specifikaciju. Podržava do 1TB NAND memorije, nadogradnje firmwarea, zatim global wear-leveling za produžavanje životnog ciklusa NAND-a, ima hardverski ECC mehanizam, detekciju internog napona, a dostupan je i u komercijalnoj i u industrijskoj verziji.

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.

Corsair je za ovaj Force LX 256GB (CSSD-F256GBLX), model preporučio cijenu od 145 USD, dok se primjerice u hrvatskim webshopovima prodaje po cijeni od oko 1.050 kuna. 128GB model košta oko 570 kuna, a 512GB model se ne prodaje u Hrvatskoj pri čemu je preporučena cijena 280 USD. Prava konkurencija ovome disku po cijeni bi trebao biti OCZ-ov ARC 100 240GB za kojeg oni traže 120 USD i koji ima tek nešto malo manji kapacitet. Kao što smo iz testova vidjeli, OCZ-ov je uređaj nadmoćniji u profesionalnoj upotrebi, dok će kućni korisnici teže primijetiti razliku. LX je vrlo brz kod čitanja, malo sporiji kod zapisa te ima niske IOPS performanse, no zato ima vrlo dobre 4K performanse. Sve u svemu Force LX je vrlo dobar ulazni disk, za korisnike koji nisu previše zahtjevni, i kojima će donijeti veliko ubrzanje u radu računala pri prijelazu s klasičnog tvrdog diska. Jamstvo je solidnih 3 godine.
