Sql Server Disk Configuration Best Practices
- If the expected lifetime is lower than the servers planned lifetime, then set a preemptive replacement date for the SSD.
- A few years later, we regarded term storage of data on CD as much folly as using floppy disks.
- Stripe unit size is the size of each element of the stripe, as stored on each member of the disk group.
- For systems from which high performance is required, it is essential to experiment with representative workloads and determine the validity of disk partition alignment for your environment.
- The cumulative effect can contribute to substantial performance degradation.
- We have two hosted SQL servers with them and have been pleased with the performance. Internally we stayed with SAS drives for this refresh.
- Perhaps you should consider that before calling my comment "asinine". –Dave Van den Eynde May 18 '12 at 17:52 add a comment| up vote 1 down vote eSATA is your friend

Even for high IO load applications like a very active database a good SSD is not much more likely to ware out before routine replacement then a spinning disk. Bonuses Within 6 months I don't think wear level will even be brought up anymore, it's progressed very well, very quickly. –Nick Craver♦ Sep 27 '09 at 13:47 1 Good answer.

Disk latency is a fundamental measure of disk performance. Terms Discussion of disk I/O includes terms that are often used ambiguously and interchangeably—sometimes reflecting accepted definitions, sometimes not. Configuring optimal disk performance is often viewed as much art as science.

In addition, with this approach the backups are written to a RAID 0 set which does not have any redundancy so a maximum amount of storage is available for the backups Volume Serial Number is 1CB7-C6C4 NULL Directory of C:\WINDOWS\system32 NULL File Not Found NULLwhich is not my desired output.

Partition alignment must be explicitly performed. In the absence of definitive information, consider implementing disk partition offset with the Windows Server 2008 default of 1024 KB. For more information about how to execute partition alignment, see the “Implementation” section later in this paper. It also addresses issues to consider regarding vendors.Essential Correlations: Partition Offset, File Allocation Unit Size, and Stripe Unit SizeUse the information in this section to confirm the integrity of disk partition
