Introduction Ext4 is the evolution of the most used Linux filesystem, Ext3. In many ways, Ext4 is a deeper improvement over Ext3 than Ext3 was over Ext2. Ext3 was mostly about adding journaling to Ext2, but

Solving the ext3 latency problem [LWN.net]
One might think that the ext3 filesystem, by virtue of being standard on almost all installed Linux systems for some years now, would be reasonably well tuned for performance. Recent events have shown, though, that some performance probl ems rem ain in ext3, especially in places where the fsync() system call is used. It's impressive what can happen when attention is drawn to a probl em; the 2.6.30 ke

SSD vs. SATA RAID: A performance benchmark | Linux.com | The source for Linux information
By Ben MartinÂ¬ï¿½ï¿½ Without going into details, SSDs may use single-level cell (SLC) or multi-level cell storage, with SLC drives typically offering better performance. SSDs offer different read and write speeds, form factors, and capacity. I looked at several models from Mtron. The performance of the 3.5-inch and 2.5-inch form factors is identical, so you might as well get the 2.5-inch drive because
