Hvilken HDD?

Skrevet af Lars. Sendt til Harddisk

Hvilken Harddisk skal der vælges når den nye NAS er er indkøbt?

WD har som de eneste på markedet udviklet en harddisk serie specielt designet til NAS enheder til hjemmet og mindre kontorer.

Navnet på denne serie er RED. Harddiskene findes i øjeblikket i fire versioner: 1 TB (WD10EFRX), 2 TB (WD20EFRX), 3 TB (WD30EFRX) og 4 TB (WD40EFRX) - alle med formfaktor 3,5". Ud over kapaciteten på harddiskene, er der ikke forskel; De kommer alle med en cache på 64 MB og et SATA 6Gb/s-interface. Strømforbruget ved brug er på blot 4,60 Watt, idle-forbrug er på 4,10 Watt og ved standby/sleep er forbruget på 0,60 Watt, for den største model.

Den primære forskel som udskiller RED fra andre harddiske, er Western Digitals firmware til disken - det såkaldte NASware. Dette optimerer diskene til NAS-brug ved at forbedre fejlrettelser indenfor blandt andet RAID-miljøet. Hvor normale diske kan "falde ud af" et RAID i forsøget på at rette en fejl, gør RED-diskene ikke. Varmeafledning, støjniveau og streaming af film er desuden optimeret til NAS-brug.

Støjniveauet for WD RED serie ligger en smugle under deres GREEN serie.
WD GREEN SERIE: Idle mode: 24 dBA (average) Seek Mode 0: 29 dBA (average) Seek Mode 3: 25 dBA (average)

WD RED SERIE: Idle mode: 23 dBA (average) Seek Mode 0: 24 dBA (average)

Priserne for WD RED serie ligger i et niveau som de fleste bør kunne være med på.
1 Tb ~ 600 kr
2 Tb ~ 800 kr
3 Tb ~ 1000 kr
4 Tb ~ 1600 kr

Med i denne pris følger en producent garanti på hele 3 år.

Jeg har fornylidt modtaget et par diske på prøve fra WD RED serie. Disse vil fremover bleve brugt i test af diverse NAS enheder.
