Be glad to send you the paper

I would be more than happy to send you the white paper but do want to mention somebody posted the link to it in this thread. Here is that link http://download.intel.com/support/motherboards/server/sb/enterprise_class_versus_desktop_class_hard_drives_.pdf

You might notice that this document talks primarily of the 15,000 RPM enterprise class drives and is applicable to the 7200 RPM versions as well. Here are a couple of links to vendors that make the drives i am talking about and have had great success with.

The Seagate one http://www.seagate.com/internal-hard-drives/enterprise-hard-drives/hdd/enterprise-capacity-3-5-hdd/

The Western Digital one http://wdc.com/en/products/products.aspx?id=30

I have found these drives to be incredibly reliable. In commercial applications I used these in 24/7 mode often writing several Terabytes of information to them every single day. In other words i am working them much harder than the average person ever would. I have built hundreds of systems using these drives with great results.

I also noticed somebody made mention that Solid State Drives do not have long term reliability. That may be true if they are used incorrectly and the wrong type used. I have used solid state drives in mobile systems that are subject to extreme vibration and temperatures in the range of -10F to 110F with 100% reliability. These units have been in place for 4 years with no failures. I very carefully pick the hard drive manufactures and their model numbers that will fit my needs. Do to the fact that is kind of another subject I will not go into details unless asked.

Just an FYI the laptop I am typing this on has a 512 GB Samsung 830 series SSD and has been extremely reliable. http://www.samsung.com/us/computer/memory-storage/MZ-7PC512N/AM?

My laptop has a 2.7/3.4 Ghz processor and boots in 12 seconds. I love SSD's but do not use them in enterprise applications
