That's funny! BuyVM storage is the fastest in a group that includes two SSD VPSs.

And the iops is always over 9000. Now waiting your Seattle location.

rds100 · April 2013

IOPS reading on KVM are never real because the KVM guest cannot make the host node flush it's cache so your reads are coming from the node's cache, not directly from disk.

@CVPS_Kevin is there a problem with this node (tests taken between 12:30-2:00PM EDT)? On a positive (?) note, the results are very consistent...

That is SAN storage on a 1 gbps link.
New setups have FC 4 GB, but only a couple of servers in production.
We are slowly phasing out local storage after recent problems with raids and power in the MBs. Better redundancy (active-active controller and tons of spares), better resource usage (scaling) in theory should not have problems with IOPS and speeds, will see how that pans out.
P.S. Indeed, i was reading the first post and saw enetsouth... Gee, I really miss it.

Haha, if it was a LEB host everyone was like Booo, double-crosser overseller with crappy ebay hardware :P

@Maounique Can't complain since it's FREE :-)

This is the VPS that I'm going to offer as a service later:

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 tietuetta sisään
16384+0 tietuetta ulos
1073741824 tavua (1,1 GB) kopioitu1,64207 sekunnissa, 654 MB/s

dd if=/dev/zero of=test bs=1024k count=1024 conv=fdatasync
1024+0 tietuetta sisään
1024+0 tietuetta ulos
1073741824 tavua (1,1 GB) kopioitu1,56421 sekunnissa, 686 MB/s

Anyone interested on a Finnish/Finland VPS with above figures?
