    Speed: SSD > SAS
    Storage Density: SSD < SAS
    Price: SSD > SAS

    If you value more storage space for the same price, then go with the SAS drive as you'll get 480GB. If space isn't a concern and you value speed more, then go with the SSD drive.

  • Are there any way to change ssd from sas or sas from ssd?

  • Netcup SAS isn't bad either.

    You can find more of their clients SAS tests here: https://forum.netcup.de/netcup-intern/fragen-vor-dem-kauf/8149-performacevergleich-ssd-und-sas/

    @Falzo, our local netcup guru might be able to help answer that. Probably no automated means of doing it, but support might be able to help you out.

    Otherwise, you could just order a new VPS with the other drive type near the end of your billing cycle, transfer everything over, and then cancel the old VPS.

  • Netcup SAS is acctually very fast too :)

    You can probably use the snapshot via the panel which crates a QCOW2 Image iirc and then all you need to do is reinstall the new vps using that image.

    SAS. Fast enough, more storage.

  • I used SSD and SAS in netcup. SSD just a little bit faster than SAS but SAS you can get 10x storage compare with SSD.

  • Use this link instead, 2EUR cheaper with same specs. Plus you can save more on longer commitment: https://www.netcup.eu/bestellen/produkt.php?produkt=1559

    I have ordered before you send a link to me... :(
    Im trying SSD now and test it.

  • I too have SAS and speed is fantastic, but can slow down sometimes.

    My SAS root server with netcup outperforms many of the SSD VMs that I have with other providers, so if disk latency is not the biggest bottleneck for your application -> go with the SAS version for more space.

    yep , I have a Root Server with SSD , but I have started to regret few weeks later as my files grows grows and grows, that I didn't ordered SAS one.
    it's almost 8 times different space , and actually I don't need that fast I/O anyway.

  • from my experience it's like others already mentioned. their SAS arrays are quite fast, my guess would be it's heavily cached, so you don't see much difference to pure SSD. I do think they quite know what they are doing there, so I'd always go for SAS if available because it's much more value to me ;-)

    quick DD and ioping on their SAS:

    at the moment, I don't have a ssd server with them, so can't deliver more than that ;-)

    for switching systems that is nothing to be done easily as far as I know. they charge a fee if you want to upgrade to a bigger size, so probably they also would charge for a switch - if possible at all.

    more likely you need to order another one and transfer anything over. but for this keep in mind which contract term length you choose and that you need to cancel 30 days in advance.

    first run is only 355 MB/s , and others are 1 GB/s , probably because of caching ?

    indeed

  • @Falzo I dont remember if I recall corretctly but I once asked them about upgrading and they said they would be indeed charging a fee. Im not sure about the actual fee but I think I told you about that and it was quite high.

  • I get answer from netcup team about change ssd to sas, that's not possible, because they use different hardware, so if anyone wolud like to ssd upgrade to sas, need to order new configuration with sas storage!

    yeah, sadly like I already guessed. so that's nothing for the undecided, especially not if you want to order yearly to take advantage of the discount...

    on the other hand the number of the DDs you ran are quite impressive and definitely above the SAS numbers. though we somewhere already discussed that this might be related to heavy caching and also can drop if the node/storage cluster gets filled up ;-))

  • Whick root server do you have Falzo from netcup?

    at the moment I am running a VPS 1000 (from their vserver line) which is on SAS and which I benched above, but also have a rootserver special from last christmas which is like the RS 500 G7 also on SAS - I just ran quick DD on that for you too:

    I also have a S 1000 from their storage line, that 1.5TB aren't slow either ;-)

  • It looks good!
    Im thinking about how many online people can served root server rs 2000 g7 Se, that i ordered.

    (I have other server at aruba cloud, 4cpu, 8gb ram, 160 gb ssd, and its working good with my webpage and there are 300.000 unique visitor/month, but i pay about 30 euro/month and i think sometimes aruba have internet connection problem, because after 1-2 month my server is online, but the internet connection will be too small for 1-2 hour, thats the reason why would like to change vps and the price...)

    I find all of root server offer:
    https://www.netcup.eu/vserver/uebersicht_vserver_angebote.php

  • I totally forgot about that listing... thanks for reminding ^^

    the rs2000 should be quite comparable to the aruba one I'd say. for the network capacity I honestly can't tell because I don't run real high traffic sites anyways, so never saw real problems (for me) either with aruba or netcup ;-)

  • I use some aruba small 1 euro servers too, and sometimes has problem with internet connection, but the server is working good.

    How much storage does it really have? It says 4 x 120 but I doubt that, better to pay 1 EUR more and get double the ram with rs 1000.

    You can calculate raid here
    4 driver X 120 gb in raid 10 = 240 GB

    as @pcszervit already mentioned all their disk-space is delivered in raid10 (which you can't change) so that 4x120GB should translate to around 240GB of raw usable space.

    the christmas special even came with 320GB usable (but only 1 core).

    at least here you still get 2 cores with the small one, so the benefit of the bigger one really is double the ram and around 80GB of space more if you go for SAS. probably always depends on what is needed if the smaller one makes sense to spare on some bucks ;-)
