Why is Hosted Disk Space So Expensive?
dhclab49 asks: "Recently, I wrote a data-driven web application for a customer, and when it came time for them to select a hosting company, what I found was that most hosting companies charge a LOT for disk space. Most of them have accounts for $10-$30 per month, a bit more if you add in a database account. However, they almost all limit you to around 250MB of disk space, with extra space costing like $1/month per additional MB of storage. The app I wrote manages the customer's workflow and is meant to allow them to generate PDF documents and store them online, so I really need a few gigs. In an era where hard disks cost about a buck a gig and are getting cheaper by the day, how can hosting companies charge $1000 per gigabyte per YEAR?! And are there any alternatives out there for hosting a data-driven website at a reliable datacenter with a few GB of space for under $500/mo?"
disk space for gigabytes worth of data is a relative non-issue --- it's possible for home machines to hold a terrabyte or more worth of data. the question is, how much does it cost to back that data up? my dad sells storage area networks and tape backup systems and i can tell you that there's a lot more than just having some monkey cpio / tar the filesytem --- there's a lot of potentially very expensive hardware and software involved for full backup stuff. just my $0.02
Anyone who has or currently works in the hosting industry knows there is a lot more to the cost of operations than just HD space. Of course, when you use the word, "Datacenter" are you then talking about high-speed SCSI drives in some sort of RAID array? With that, even HD's can get expensive. Colo is the way to go, just setup a cheap server with big IDE drives and maybe an ARAID or something and get someone to stick it in their room for $200 a month.
