Hi,
Looks like they are getting their server from ServerMatrix:
Super Server 3.0
3.0GHz P4, 800MHz FSB
80GB Drive
1024MB RAM
1200GB Bandwidth
100 Mbps Ethernet Port
Red Hat, FreeBSD, Windows
$139 Monthly / $149 Setup
$149 Monthly / $99 Setup
$159 Monthly / $49 Setup
$169 Monthly / $0 Setup
It is clear that they are doing overselling. The server has only 80GB HDD. If they do not do overselling, that means they are hosting 5 such accounts on the server. 5 x 15GB = 75GB. Their income would be 5 x $12.95 = $64.75/month
Assuming they paid the most setup fee to ServerMatrix, they will be paying $139/month to ServerMatrix. To be logic, they won't do business at loss: $139 / $12.95 = 10.73 accounts ~ 11 accounts.
11 accounts must be hosted in order not to lose money. That would be 11 x 15GB = 165GB occupied by their clients. 80GB - 165GB = -85GB. Where did the -85GB come out from? They are doing overselling.
Bear in mind, the above calculation is counted by assuming they don't earn a single cent. If they want to earn more, they will host more clients on that server and the server would be crowded.
Instead of being greedy and sign up for their 15GB plan, I suggest you to pay $12.xx to other hosts that can get you 1GB space. That is more logic and you get what you paid for.
FYI, they put an Alertra icon there, but it is not linked. Guess they either do not have good uptime or they simply can't bear the cost for Alertra, so they have taken it down.
Anyways, the decision is with you. If you decided to try them, do give us feedback later
Thank you.
