I think there is some information lacking re the differecence between NDAS and NAS.
NDAS makes the drive appear as if it is directly attached to the machine and transmits all the raw data it would transfer across a USB port across the Ethernet.
This has severe limitations which have not been pointed out here and I think haven't even been examined or encountered.
The primary limitation for a mixed platform workgroup is that only ONE person can write on the box at a time!. I think this is quite fundamental.
If it is on an all windows network simultaneous writes can be performed but I wonder what it's performance impact would be in this situation.
Page 14 from it's manual:
DO NOT perform disk operations (format, partition and chkdsk) when multiple PCs have the INTEGRAL
LAN drive mounted.
The INTEGRAL LAN device can be formatted, partitioned, chkdsk, aggregated or mirrored when ONLY
one PC is connected.
• The INTEGRAL LAN can be shared by a mixed
of ME/2000/XP and Mac computers
• Multiple computer can have READ ONLY access
• WRITE ACCESS is assigned to one computer at a
time and is passed from one computer to another
• Windows XP/2000 only network environment
• Multiple computer running XP or 2000 can
have READ and WRITE access simultaneously
It does have some interesting capabilities because of this though. It could be used on an exchange server to do certain maintenance tasks that demand a locally attached drive (this would be the only way to do it over the network). Tasks such as Offline defragmentation.
Also what appears to be flexibility of RAID and that it supports native file formats is probably a result of one thing - that it is directly controlled by the host (hence the D in NDAS). It doesn't actually support or use any file system per se - it doesn't care as it doesn't manipulate it. All the circuitry in this box is doing is just transmitting the signals that would normally come through USB through TCP/IP ethernet.
Another thing to consider if considering the RAID aspect - as it is effectively a direct drive setting up two of these devices on the network to form a RAID mirror or RAID 1 does it create twice the data over the network as the host itself is doing the RAID?
These are the things that I would expect to see tested. Can we have another review/test please??
