EBS Volume Management

EBS volumes should be created in the same region as the instance and then attached.
Performance can be increased by aggregating EBS volumes into RAID 0 or RAID 1 arrays (Linux). This improves both performance and storage space.
hdparm -Tt /dev/sdf and ioping -R are useful Linux commands for I/O monitoring.
By default, EBS volume replication occurs within a single Availability Zone. Multi-Availability Zone redundancy requires enabling this feature.
Creating snapshots of EBS volumes allows for replications and point-in-time restores, as well as archiving.
An EBS volume can only be attached to one EC2 instance at a time, but a single EC2 instance can be attached to multiple EBS volumes.
EBS allows for data separation from compute instances, ensuring data persistence. Multiple EBS volumes can be attached to an instance for data striping and increased performance.
EBS volumes range in size from 1 GB to 1 TB.
