DD Test Results
I created a script for ddtest.. and here is the results.. hope this will help somebody...

1 - Need to see the actual commands to know anything about these tests.
2 - SSDVM is closing.
3 - Server.Bear.
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync;
thanks OP I came buckets
`dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

Best result in my 192 MB OVZ out of 3 tries.
Finally the winner is @prometeus
Avg:- 205.3333333333333 MB/s @prometeus
Total tries: 3
it seems my fake dd binary is doing a great job! :P
This is the results in VZSSD7 Prometeus :
In VZ3, it's about 200MB/s
@ErawanArifNugroho
Got 707 MB/s in VZSSD7.
O_o
Yes, the VZSSD in the previous offer, before black friday
OneAsiaHost KVMSSD-512 plan:
Where did my 300MB/s go ;_;
Y U DO DIS TO ME @Francisco
Ticket and we'll see?
We've got some upgrades coming for December in SJ so that should clean up that all
Francisco
Nah, I'm fine with it. For all it runs, it'd probably be fine with 10M/s, even (Hurrdurr IRC Bouncer)
Just complaining for no reason other than anything :P
( @Francisco )
I am now more convinced that ever that people just buy VPSes to run dd tests.
Inception:
It is a point in time test on a shared resource environment using sequential writes only.
Will the madness ever end?
Cloud Shards:

Not by me
Next big thing?
Yup, not sure why peeps don't get this. Its an indicator but a single (or at best typically 3 indicators) rather than performance over time. That's why I like what @serverbear is trying to do with his trended testing.
Yep.
This thread is really silly, and that's coming from someone who puts a lot of money into having good DD results.
Probably they wish to bypass the cache since most providers only activate it for reads.
I never understood this thing, for me 30 mb is the limit where i start to see delays in stuff and is the lowest acceptable limit for a payed VPS, but that varies. Some providers (of free VPSes) are doing fine with only 10 mb, i guess it depends more on the read speed and this is normal since 1/5 of all IOPS are usually writes, the others are reads. ioping gives a much better idea of how oversold the IOPS are.
I don't object I suppose as everyone has to learn at some point, but the picture in my head goes along these lines:
1) Buy VPS
2) Woohooo 400 MB/s sequential writes on dd test
3) Install highly optimised LNMP or LLMP stack using someone else's script
4) From that point on everything I do is based on having good read speeds which I never tested and I will never ever run anything ever that requires fast sequential write speeds from step 1
herp.
Is this advertising time?

People want good dd test results. They may not need them, but the people have spoken, so it's obviously a strong marketing point.
While Prometeus seems to be ahead in this thing, it does not mean we shouldnt explain things.
OK, the customer has spoken, no problem for this, if they want it, they will get it, but they must know that asking things they dont need will only drive prices up for a gain that is not noticeable in daily usage.
For the storage plans I am putting up, the dd with 192 MB ram is over 100, for a storage plan the dd test is actually more relevant, however, the network will never saturate that write speed, even if the port would be 1 gbps. So, unless you are copying stuff from one folder to another, that is a resource that will never be used.
Hmm... probably someone should start testing memory speed by writing into /dev/shm as well.
@jarland if that is your opinion then why would you show results that are only 50% of your competitors?
this dd thing makes less sense every day.
indeed.
I just dont accumulate lebs to get good dd results.. i have 60 sites... and i dont want to put more than 4-5 sites in one vps.. so 17 boxes now...
i know dd test is just one factor... i give top priority to uptime and overall performance.. my main sites are hosted with inceptionhosting, quickweb, hostigation, buyvm and chicagovps... that doesnt mean others are bad.. some boxes like securedragon and mini vps worked well but because of low mem (128) i was not able to install virtualmin..
i really had problems with only few... like avante hosting... alienlayer (but now they seems to be better.. but slow...)
@zon
Your websites do writes more than reads?
@zon yeah no offence intended, but this bench mark has almost nothing to do with how a site will perform in the vast majority of cases
@eLohkCalb
my main sites are photo gallery types.. so mostly read... and we upload pics 1-2 times daily only...
@AnthonySmith thats is correct... but with my experience if a dd test is giving very less values like 20 or 30 most of the times then it will affect the site performance... i had some boxes like that and i closed it..
