amazon web services - EC2: How to tell if disk volume is instance store or EBS? -

I have the volume associated with a Windows EC2 frequency (similar size) in Amazon AWS.

One of these is called the Instance Store, the rest are EBS.

How do I tell which instance store? They all look the same in all Device Manager - "XENSRC PVDISK SCSI Disk Device"

Could not help in speed testing, one of the drives is slightly faster than others, but how can I ensure that it is an instance store?

I did this in the last week with Anix server in Annees! . If you want to see which ones are actually available, see entries in block-device-mapping. I am showing the following with curl and a Linux host because it is easy to illustrate:

  $ curl http://169.254.169.254/2014-02 -25 / meta-data / block-device-mapping / ami aperral 0 $ curl http://169.254.169.254/2014-02-25/meta-data/block-device-mapping/ephemeral0 sdb  

In this case, sdb (or xvdb) is an instance store.
