First off, this is not a typical WHS build, and it was not meant to be. For the majority of users, a HP MediaSmart (by far the WHS to get if you do not DIY the build) is the way to go. For my purposes, I have seen a consistent, but increasing 500-600GB/mo of extra disk usage. Just for the record, unlike the opinion of certain Seagate executives, it is not for material of questionable moral value. Alas, I needed a solution that would allow me to have one box that could be upgraded and used for up to 24 months. As mentioned in Part 1, this project is an upgrade project and therefore I had some parts, and had a good idea of what I was doing before embarking on the project.
About 10 months ago I decided to enter the world of the Windows Home Server. My storage arrays had outstripped my Cosmos S’s capacity, and running multiple controllers for all of the SAS drives as well as SATA storage became too much. My decision to build a WHS v. buy one was made due to sub-$100 Seagate 1.5TB 7200.11 drives (at the time very inexpensive) so I bought another eight drives just to fill up an 8 port raid controller.
For Small Business Servers and home servers, one thing becomes apparent, the need to use raid with large data sets. Raid 1 and software mirroring technologies like Windows Drive Extender are too cost ineffective for large storage arrays. For example, if one has 1 TB of storage need and uses one of these mirroring redundancy option, they need 1TB extra storage for a complete backup. Likewise, if an administrator uses four 1TB drives for data storage, then another four 1TB drives would be needed for redundancy. Raid 5 offers a user with both more performance than Raid 1 and lower “lost” capacity due to redundancy storage. Instead of effective storage capacity of n/2 [...]
A 32GB SSD drive for $60 after MiR sounded like a good idea, especially since that would be great for a Windows Home Server C:\ drive, so I purchased a Patriot PS-100 32GB. (It should be noted that I have not seen the price for $60 again in the following 3 months) 64MB of cache sounded better than a JMicron JMF602 based drive, and surely Patriot would not release in the fall of 2009 a JMicron branded drive. I assumed that the drive would be Samsung, Indilinx (akin to an OCZ Core V2) since 32GB was not an Intel controller sounding size (40GB, 80GB, 160GB MLC to date). My conjecture proved to be inaccurate.
Also, just for comparison here are Raid 0 Benchmarks with the PS-100 [...]
