SSDVPS - First Experience
I thought I would purchase on of these
http://lowendbox.com/blog/ssd-vps-7-2gb-ram-40gb-ssd-openvz-in-los-angeles/
1) All emails sent from their systems are sent as ssdvps@main . After not receiving the activation emails I discovered our mail systems rejected all their emails as their sender address is not fully-qualified but rather "ssdvps@main"
2) Loaded up Centos 6.4 and performance was very good, diskio at approx 280MB/s. After installing cPanel I found that cPanel quotas not working. After doing the usual checks I submitted a ticket to ask if secondond level quotas are enabled on the VPS, and I get the response below.
_Hi,
I recommend http://www.platinumservermanagement.com/ as our services are self managed._
When I queried the response, it is evident that they don't know what I am talking about Now
Does anyone else know about ssdVPS?, as right now I have some concerns about their technical capability.

If they can't figure out how to enable second level quotas...CANCEL.
edit: this provider is the one who when they were asked why their WHOIS info has the address of their data center instead of their business address responded:
Run...
Cancel...
Check the offers section here for one of the many hosts who know what they're doing....
On a "pure" SSD node?
Well it looks like they came good, enabled quotas and closed ticket.
Just doing a dd, today its approx 230MB/s
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

Pure RAID-1, duh
My SATA setup's in RAID10 are pushing more than that > 350MB/s
SSDVPS's test results when they posted their LEB offer last month were in the 650-680 MB/s range. The test results people have posted have been dropping steadily to the 200-280MB/s range as their node(s) fills up.
PureSSD comes in many flavors. :P
Slow Flavor: This result is from my VPS at a Spanish provider with "pure SSD" nodes...they're running OpenVZ inside of KVM

Fast Flavor: this is my dedicated server with SSD drives at Seflow

The dd results from one of my VPS's on a RAID SATA (w/SSD cache) node at Iniz NL are 9x faster than my "pure SSD" VPS in Spain

TL;DR: buying a "pure SSD" plan doesn't always guarantee blazing speed.
This is why I hate that terminology...
