NAS comparisons

Hi! I hope someone could provide me some help and information about this...

I want to add a new storage to my business network (1GB LAN connection, about 30/40 users), what are the differences (specially in performance) between this 3 options:

1- NAS Synology DS211
2- FreeNAS/OpenFiler
3- Windows Storage Server 2008 R2

I need this for backup and to store some VMs. Do you recommend another NAS option?

Thanks!

The big difference between the 1st option and the other 2 is that you'll need to buy some serverhardware to put it on.
If you buy a synology nas, you don't need the serverhardware.
Even if you buy the windows storage server, you'll need to buy a license on top of that also.

So, if you're on a tight budget, like most smb's are :-), i think you'll better buy a synology.
I don't have any experience with synology, but i do have 2 QNAP (http://www.qnap.com/index.asp) nas devices at home.

Qnap has a builtin backup system and has virtual disk and iscsi support.
Depending on the type of device and disks you'll choose, these devices have enough troughput to serve your 30 users.

Check this 2-bay QNAP compared to your 2-bay synology.
Nice is: it's vmware certified

the main difference is that if you loose a disk drive in first  option, the chance that you will lose the data is too high to go for the risk. there is no scalability and honestly no future of that product in your environment.

there will be authentication problems in the second option perhaps if you use active directory so why dont you do things easily and do not go for option 3 directly?

What about an open-source iSCSI like SCST ?

It could easily provide your existing servers with new iSCSI volumes and spaces.
