The New Linode Cloud: SSDs, Double RAM and much more

Throughput speed is not everything, in many situations latency is more important. Can you give results for this?

dd if=/dev/zero of=test bs=512 count=1500 oflag=dsync

I'm getting "6.40264 s, 120 kB/s" on my laptop's SSD, but on a proper server with a RAID card and cache enabled I get "0.187033 s, 4.1 MB/s".

I did 7 runs of your test and the average time is: 0.424795s. Example run:

  $ dd if=/dev/zero of=test bs=512 count=1500 oflag=dsync
  1500+0 records in
  1500+0 records out
  768000 bytes (768 kB) copied, 0.427272 s, 1.8 MB/s
