HDD vs SSD durability
After reading Jeff Atwood's recent blog post on solid state drives, I'm somewhat deterred in wanting to own one. I basically want to use solid state drives in my home network for the following purposes (all machines running 64bit Linux):
- My main (pwn3r) desktop computer. This will be my main workstation for work, video encoding, etc. This will be running an Intel 980x 6-core processor, making it a beast. My hard disk configuration will be:
- RAID-0: 2 Crucial 128GB Solid State drives for the main operating system(s), essentially providing 256GB of incredibly fast storage.
- RAID-1: 2 WD 2TB Hard Disk drives for media and backup storage.
- My network firewall computer. This will be running Untangle on my home network for content filtering and firewalling (if that's a word). It will be running an Intel Atom D525 dual core 1.8GHz processor. The hard disk configuration will consist of a single small 16-32GB solid state drive for the operating system and little, if anything, else.
- My home HTTP/SFTP/file/backup server. This will be running a dual-core Intel i3 processor; it will be used for some video encoding, as a local DLNA server, a HTTP server for a few largely static files and perhaps some interactive scripts, a SSH server, possibly OpenVPN, and will be used to back up critical files over the network. It will be running RAID-X (where X > 0), meaning RAID-1 or RAID-5 or 6 for fast, redundant data storage, as well as a small SSD for the operating system.
I'm not exactly made of money, and I can't really count on buying four new SSDs every year or so. I can understand replacing them in computer number 1 once a year... maybe, but for the other computers which won't be utilizing the drive very much (ie: they're not power machines), it seems ridiculous to buy new drives this often.
My question is this: can I actually depend on solid state drives like I would on hard disk drives? Also, is this the best economic option? I'd like to save as much power and heat as I can, and solid state drives seem to be the best option at this point.
