NDAS vs NAS Architecture Features
NAS

• NAS external drives mostly run on a Linux O/S
  with low-end CPU and Memory.
• Slow File Transfer Data is processed by CPU
  and OS to be accessed, causing CPU bottleneck.
  15MB/s
• File Level Access (limited application for disk
  usage)
• Network storage handles all processing (heavy
  traffic lags down performance.)
• Drive ready in 3070 seconds (need to bootup)
• No RAID Support
• No Direct connection (must use as NAS only)
• FTP / Samba / Print Server

• No CPU or OS. NDAS Chip handles all.
• Fast File Transfer Direct data transfer.
  between NDAS and PC (host). 60MB/s
• Block-Level Access. (Broad application for disk
  usage)
• Secure network storage. No IP address required
  (invisible to external computers).
• Drive ready less than 10 seconds
• RAID 0,1 support. Aggregation Support.
• USB e-SATA direct Connection (portability)
• Network Backup S/W Acronis True Image

• EASY TO USE Network Drive
• ShareDisk appears and works just as a local hard
  drive.
• Continue saving, copying, moving files just like
  your C Drive, while sharing the files with

Just plug in additional drive in the network as
your storage need grows. Use additional disk
separately or combine them to create a huge disk.

NDAS Only Features
Mirroring(RAID1)
Mirroring makes sure you dont lose any data.
Should one of the disk fails, the mirrored disk
will automatically replace the failed disk.
8
NDAS Only Features
Striping(RAID0)
Striping feature strips the data into parts and
distributes parts of the files to the striped
disks. Unlike aggregation, this feature enhances
data processing speed.
