The process of resizing the snapshot space can take awhile depending on your data volume size and 
the number of files in your volume.  Expanding the snapshot space will reduce your data volume 
size, and reducing the snapshot space will expand it. 
Note 
Due to the nature of how snapshots work, you will encounter a drop in 
write performance when a snapshot is active.  If your environment requires 
the highest throughput in performance, the active snapshot should be 
deleted, or you should set a limit on how long the snapshot should last. 
USB Storage The USB tab displays the USB disk and flash devices connected to the ioSafe R4, and offers various 
options for these devices.  A flash device will appear as USB_FLASH_1 and a disk device will 
appear as USB_HDD_1.  If you have multiple devices, they will appear appended by an increasing 
device number, i.e. USB_HDD_2.  If the device contains multiple partitions, the partitions will be 
listed beneath the main device entry.
