This week we will be discussing Solid State Drives as the final installment to our Component series. In addition, we have a very special guest, David McCabe of the Home Server Show, to discuss his recent build. Listen to show for more information. We hope you enjoy this episode and remember to post your comments and questions on the forums.
David McCabe’s Vail server build
What is an SSD?
SSD Form Factor
Most of the modern SSDs are the standard 2.5” size with a few models in the 3.5” and 1.8” drives form factor. Most SSDs are SATA II (3 Gb/s) with a few ready for the SATA III (6 Gb/s) interface. Prices as of today start around $85 for a 32GB model, $150 for a 64GB model and go up from there. Newegg has about 150 active models with most in $150 to $300 range.
Oh, and one final special form factor…PCIe SSDs. These drives are smoking fast at speeds of 800 or more but they cost thousands of dollars. They are a very small percentage of SSDs and crazy expensive. You can ask us about them in the forums if you need more information.
TRIM is a way of allowing the operating system to communicate with the SSD about deleted files and formatting so the SSD can perform faster. Windows 7 and Server 2008 R2 support TRIM and Linux 2.6.33 or later. If you want TRIM and do not run one of these operating systems there are utilities from companies like Intel and G. Skill that send the commands manually.
To check if Trim is enabled:
Type at Command prompt "fsutil behavior query disabledeletenotify"
DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
