Hard Drive,
I need a new hard drive at the moment i am using SATA 8mb 80GB hard drive. My current work involving read/write a huge date 6 GB dataset, For some reaosn I found that my current drive is too slow.
So I am thinking to buy new hard drive ... what technology and brand do you recommend for my case? Could you please be specific what brand should I buy when giving an advise to me. Well kind of confused of terms IDE And SCSI, SATA , etd
cheers,

Like Burrcm, I suspect that you are barking up the wrong tree and that the drive is not the problem in terms of speed.
I don't think the drive is the reason for your performance problem either.
Servers usually use many SCSI disks in raid5 configuration. Raid 5 needs at least 3 disks, one of which the capacity is lost for redundancy. The more disks you have the higher speed you get, as tll disks get data at the same time.
Modern servers today also start coming with SATA disks, after all, it is much less expensive than SCSI.
But, normal Servers always use raid.

OK, so how to do indexing and defrag on Linux system? btw, I am using replayfs
Well you have jumped off my branch. "linux defrag" into google indicates that there are plenty of options in this regard.

Also, modern databases are usually indexed internally, not by the filesystem. Check the documentation of the database system you are using.
Linux file systems don't NEED to be defragged, unlike windows they are properly programmed.
if you are accessing huge files, increase the cluster size to like 64k or more. Larger clusters will allow faster usage of your hard drive.

which contains GBs datasets i.e I need week1-5.
Do you think SCSI it wll make a significant different when reading this dataset? Which one is faster ? RAID with 4 hard drives or SCSI?
Also what is Enterprise SATA?

Say for example for a server, do they run in SCSI or RAID?
