RAID med disker på 2mb cache og 8mb cache

[moffeloffen]

Hvis man kjører to hardisker i raid, har det mye å si for ytelsen hvis det er 2 eller 8 mb cache?

Noen som har noen linker eller tester av dette?

 

Tenkte å bruke WDC disker

I tester jeg har sett er IBM veldig raskt i RAID. Du burde bruke så raske disker som mulig, og 8mb versjonene er raskere enn 2mb versjonene.

ooking at their amazing transfer rates under RAID 0 it's safe to say that both the IBM 120GXP and the Western Digital 1000JB are excellent choices. But the 120GXP is our recommended choice for RAID 0. One reason is the lower power consumption and the lower temperature. This is important when coupling 2 or even more disks for RAID operations. Another reason is the cost: 2 of the aggressively priced IBM 120GXP (40GB) cost less than 1 unit of the Western 1000JB, provide only 20% less storage, but perform when RAIDed clearly faster than a single 1000JB with 100GB. The Maxtor D740X would be again only our third choice. The volatile transfer rate diagram is a reason for concern.

 

1st choice: IBM 120GXP

2nd choice: Western Digital 1000JB

3rd choice: Maxtor D740X
