i have a seagate 40GB disk but it has a not enough capacity disk for my video capturing needs. i need a biggest disk. i know it exists 120GB models but i have heard we can find highest capacity disks. is it true? then how much capacity we could expect and what are they?
You have two option. 1)Buy three identical HDD as the hdd you already have, a Raid controller (i.e. Promise Fasttrack100 TX2), build a RAID 0 array with four hdd for a total capacity of 160 GB. The same you can obtain with other hdd, but they should be preferably of the same kind. Two WD 1200JB or two IBM 120GB 120GXP will give you 240 GB on line, four hdd 480 GB on line and amazing performances topping the PCI bus capability (133 MB/s)
2) Buy a 120 GB or 160 GB HDD (for 160 GB only available is a MAXTOR 5400 r.p.m.)
Four IBM 120GXP 120 GB on a RAID 0 controller can give you 480 GB online, up to 100 MB/s as continuous transfer rate and a score of 65000 with Sandra 2002. The whole array, including the controller, will cost you about $ 900 .
