Difference between v3 and v4 of GS724T

What is the difference between the v3 and v4 of the GS724T switch?

 

Amazon has both, although the v4 is not available from as many sellers and has a higher price. I also found a page that warns v3 and v4 models cannot coexist on the same network, although this sounds highly unlikely.

 

My primary need is for a fanless switch that can network three NAS devices each with 4-channel 802.3ad LACP, a couple wifi access points, and connecting these upstream with another 802.3ad LACP capable switch. I'm not making use of the VLAN features.

    Hi mcgroarty1,

     

    A. The GS724Tv4 supports the following features below while the GS724Tv3 does not.

     

    1. Dynamic VLAN Assignment 

    2. Energy Efficient Ethernet (IEEE 802.3.az)

    3. MLD (Multicast Listener Discovery) Snooping

    4. DHCP snooping

    5. Dynamic ARP Inspection

    6. Multicast VLAN Registration (MVR)

    7. Multiple Registration Protocol (MRP)

     

     

    B. Other differences between GS724Tv4 and GS724Tv3:

     

    1. The GS724Tv4 has a MAC Address database size of 16k while the GS724Tv3 has only 8k.

    2. The GS724Tv4 supports IGMP Snooping v1/v2/v3 while the GS724Tv3 supports IGMP Snooping v1/v2 only.

    3. The GS724Tv4 has a flash memory size of 32MB while the GS724Tv3 has 16MB.

    4.  The GS724Tv4 has a 128 MB DDR2 SDRAM while the GS724Tv3 has 16 MB DDR.

    v3: http://www.downloads.netgear.com/files/GDC/GS716TV2/GS716T-200_GS724T-300_DS_24Feb1218-5327.pdf

     

    v4: http://www.downloads.netgear.com/files/GDC/datasheet/en/GS716Tv3-GS724Tv4-GS748Tv5.pdf

     

    Unfortunately the documents are formatted very differently so it's difficult to do a side-by-side comparison. So far all I've found are iterative improvements. The v4 shaves a few watts off of power, quadruples the storage buffer per port from 512KB to 2MB, and has a slightly faster switching rate (48 vs 52Gbps). I don't spot any regressions or stand out new features.
