Split Partition Performance
Jtonline Apr-13-02 12:24 PM
I recently got a new Maxtor 40GB upgrade however, it was setup with two partitions, 20Gb each. Is there a reason for this? Will it affect performance if I merged them? Also if I'm to run linux on one of the partitions, will it be better to resize the Linux one to 500mb instead? I don't plan on doing anything extraordinary with Linux except learn and fool around.

Thank you

What version of Windows do you have installed/will install? Larry

I would partition at least 2 GB for Linux, and don't forget about your swap file. I would also recommend GRUB for dual boot.

Partitioning a hard disk drive makes it faster. To put it simply, the drive does not have to move the heads as far to read and write data (clusters, chunks of data, groups of contiguous sectors) that makes up files and may be scattered all over the partition. Each partition has a File Allocation Table, which maps clusters to files. Also, in general, the larger the partition, the larger the cluster size. For example, a 20 GByte FAT32 (you may be using NTFS with XP) partition uses 16 KByte clusters. If a file is only 2 Kbytes, it still uses at least one cluster, or 16 Kbytes. 12 Kbytes are wasted. In comparison, a 10 GByte partition uses 8 KByte clusters. Finally, running defrag on a partition will make it faster be rearranging the clusters making up a file on partition so that they are, as much as possible, sequential and contiguous. Once defragged the drive doesn’t have to move the heads all over the drive to read a file into memory. Defragging a 20 GByte partition takes an awfully long time. It would be better to have an 8-10 GByte C: drive. I would make it even smaller for 5400 RPM drive. I don’t know how much space Linux needs, but I would be generous and probably give it twice as much as I thought needed. There are utilities such as:
· Acronis OSSelector
· Paragon’s Partition Manager
· PowerQuest's Partition Magic
· GNU Parted
· and others available from various download web sites such as download.com
…which can shrink grow, move, and copy partitions. Larry
