Will let them know...
Thanks again,
Mike

>You cannot read data on the hard drive removed from the SC101 and connected to a PC, and vice versa
>You can format the SC101 drive, detected by the operating system, into NTFS. But it will be a virtual NTFS drive, only for the operating system itself. It won't solve the problem with readability in case of a direct connection to a computer. But according to NetGear, it may cause problems with multi user access
>
>UDP used for data transfers (Port 20001 must be open) does not guarantee data delivery, so using the SC101 in wireless environment, especially with 802.11b, is fraught with significant performance degradation

>Latencies, caused by the data backup system, result in significantly reduced performance of the file system in operations with small files

>To all appearances, mirroring is purely software. It can significantly slow down copying large files
>The writing mechanism used by the file system practically excludes file fragmentation (according to the developers). The reverse side is significant penalties for free room on a hard drive
>
>File operations are carried out without Windows cache. In most cases they take less IO operations than in case of NTFS
>
>If the free space left reaches 10% of the total size, performance drops significantly as well.
>SC101 requires an IP address for each physical hard drive plus another one for each partitio

>>>What is the EXACT NetGear External System they are using? It sounds like that is the culprit. Some models are not meant for shared access and continuous reads/writes but only for data backup such as the SC101:

>>>More info:
>>>
>>>The NAS user base represents remote offices, departments and workgroups where immediate, shared access to files is the guiding business need. Steve Rogers, vice president of marketing for Connex said, "NAS is about localization of data, not consolidation. People need edge access to data instead of having to go back to the network all the time."
>>>
>>>SANs are more loosely defined, but in their simplest form are fast, block-level storage networks. Usually Fibre Channel-based, they sport dedicated servers, storage devices, switches, routers, and other hardware and software components. Key SAN benefits include offloading traffic from the LAN, high speed data transfer, serverless backup, and improved data availability with any-to-any connectivity.
>>>
>>>SANs operate in the corporate glass house where administration is far more sophisticated and systems are vastly more expensive.
>>>
>>>High-performance database access and transaction processing are most suitable for the SAN These applications manage their own data spaces and require great flexibility on physical data locations and fast direct access to small record sets. They require block-level performance and control to reach optimum performance.
>>>
>>>NAS shines when serving applications that require shared access to the same files, such as Internet-based applications and web page serving. In this scenario, many heterogeneous servers are running concurrently, with each accessing the same web pages. Media serving is similar, with the host presenting video streams to many users at the same time.
