Hi,
I don't need Actually 10G but I wanted to put a switch in my network with multiple SFP ports and was thinking about the two switches in the Topic of this thread.
besides the Price and the higher Memory of the CRS305 , I wanted to ask some advice regarding which of these two should I most likely think about purchasing?
ciao,
Antonio
You don't need 10 GB, but you want 10 GB, or you just want a device with SFP sockets?
The CRS106 has 1.25 GB sockets:
one Gigabit Ethernet / SFP combo port and five 1.25Gbps SFP cages
In automotive comparison, your post would be:
I don't really need another car, but I need to decide between a Fiat Panda and a Porsche Boxster ...
yes I just wanted a device with SFP sockets, therefore yes I was leaning more towards the CRS106 device because of the cheaper price. on Amazon the CRS106 costs approx 64 Euros and the CRS 305 cost approx 137 Euros... more than double the 106 device!
To each their own, but allow me to be perplexed.
The whole point of having SFP's is using fiber (as opposed to copper), and the whole point about fiber is to have MUCH FASTER data transfer OR MUCH LONGER connection distances. (with increased costs for the devices, the SFP's, the fiber patches/cables, and often electricity, and renouncing to PoE that sometimes is very useful)
With 1.25 GB SFP's only the second could be (IMHO) a valid reason.
Remember that EACH 1.25 GB SFP costs 20€ or more. (10 GB ones run usually from 25 to 70 €)
The CRS 305 can use 10 GB SFP's, and from test results it switches at 80,000 Mbps, the CRS 106 at only 12,000 Mbps.
The difference in price is justified by the enormous difference in performance.
one last question on this topic, before going to the beach.. 
can the CRS305 device be configured as a router withouth repercussions? reason is I see that there are SFP /SFP+ only router for example the CCR2004-1G-12S+2XS but the cost is excessive and exagerated for my needs..
happy ferragosto!
CRS (Cloud Router Switch) should be written as Cloud RouterSwitch.
The CRS305 tests:
https://mikrotik.com/product/crs305_1g_4s_in#fndtn-testresults
give 269.9 Mbps (512 byte packet- 25 IP filter rules), so - as a router - it is roughly on par with "low speed" ones, say the hap Ax lite or the old hex (RB750GR3).
Again it makes little sense to use SFP's/optical for such low speeds.
agree with you but at this stage then from what I see the cost is 400+ euros for an SFP -SFP router... unless I'm missing something
Well, unless you state your requirements (as opposed to what you don'need but fancy, coupled with random budget expectations) there won't likely be much progress on this thread.
The OP must have a 10gig ISP connection 
If you can get by with a single SFP you could look at one of the hex series.
(perhaps adding an ethernet to SFP media converter if 2 required. eg RBFTC11)
Original hex-s, very good as a managed switch, and a very popular router.
Was quite brisk when released, somewhat slower now.
hex-s 2025, less good as a switch (ether1 and sfp connected to CPU, so traffic to them done in software), but has a 2.5G sfp port and better CPU for routing. Need to run on not less than v7.20 versions which fix some issues.
Both have poe out on ether5 which might be helpful with media converter.
People tend to forget that the CRS3xx series can do basic routing in hardware, making them wirespeed. The CRS305 can too. If you need firewalling and NAT (for use as an internet gateway, say), the CRS305 can't do that in hardware, but e.g. the CRS309 can.
Yep, but we are back to (hypothetical) budget considerations:
CRS305 149$ (4 SFP cages)
CRS309 289$ (8 SFP cages)
and we still don't know what the actual requirements are ...
today i have my NVR & Netmetal 5 access point connected to a HAP AX3 as follows:
ISP router via FWA -> Firewall system -> RB5009 -> HAP AX3-> NVR /Netmetal 5 AP
therefore my system is relativewly slow but wanted to speed up with fiber on the edge connections,
therefore I was actually looking to replace my HAP AX3 device with a device with one or more SFP cages so as to go from the RB5009 to an eventual router through SFP/fiber. would have been nice to have this router with more than one sfp cage so as to eventually in the future add a switch through SFP...
the RB5009 is part of my core network and don't want to connect any devices to this router, this is why i had the AX3 device running for about 2 years now and wanted to change the architecture....
therefore maybe my solution could be a simple hex S 2025 edition or an L009 ?
Hi Guru,
downstream from my HAP AX3 I had a CRS 112 switch and my NVR & AP were connected to the CRS 112.
I replaced the HAP AX3 with a CCR2004 ( so in the end I spent $$) and the CRS 112 with an L009 as switch and the time to access the video from my NVR app from internet went from 5-10 seconds to 1-2 seconds!!!!
I actually was not expecting such a nice outcome.. internet is internet and nothing is really guaranteed but nice to see things work out like this!!!!
Yep 
, on other news, an Aston Martin Vantage S is surprisingly faster than a Fiat Panda .
