DS410 expansion question

[ehebert719]

Hello everyone,

First of all, let me start by saying that i absolutely love my Syno DS-410. Had it for about a year and cant stop raving to my friends about it. Alas, now is time to expand and cost is definitely an issue this time around.

My question is as follows: My 4X2TB (6odd Tb available) disks in the Syno asre defined in 1 volume. As far as research goes, the way i understand it is that my options are as follows:

1- Buy a DX5 or DX510 and some disks. Appx $500-800 for Dx510 + $400(4X2tb) for disks = 1k$-1.2k$ for appx 6tb or $200/Tb*
2- Buy 4 3Tb disks and expand the volume on my DS-410. Comes down to appx $600 for disks, total net expansion of 3Tb (since i have to take out my original 2Tb drives) , so appx $200/Tb and i end up with 4 'shelved' 2Tb drives
3-Buy something like a Rosewill RSV-S5 enclosure appx$200 and 4 2Tb disks, appx $400 for a total of 600$ at around $100/Tb.

Note: the cost/Tb takes into account space not available due to raid (appx 1/4)

Question is: Are there 3rd party enclosures that are compatible with the esata port of the Syno. Could i hookup the rosewill (e-sata to e-sata) and could i manage the volume from my syno. I don't think i could span the present volume but could it be managed as a separate volume?

The other thing that worries me is that the rosewill is a Sil3132R5 esata chipset that i'm wondering if it's compatible with the syno's Sil3726 model

Any help appreciated as i'm looking for the best expansion solution for a pricepoint of $100-150/Tb

Did you ever get around to trying the rosewill RSV-S5? Is it compatible?

Regards.
