The bare minimum HDD storage configuration must be four enterprise class HDD's. In this scenario, the four drives must be divided into two independent RAID 1 pairs. The first RAID 1 pair can be small enough to hold just the Windows operating system along with at least 50% additional free space. The second RAID 1 pair must be as large as possible to hold both the video information and the database file. Please see the table below:
| Role | Disk Drives | Configuration | Settings | Partition(s) |
|---|---|---|---|---|
| Boot Volume | Two Enterprise Class HDD's any RPM/Cache | RAID 1 (Mirror) | N/A | Recommend single partition with NTFS or ReFS to hold Windows Operating System |
| Video/DB Volume(s) | Two Enterprise Class HDD's, 7200 RPM/256MB Cache | RAID 1 (Mirror) | N/A | Recommend single partition for both video and database |

In the ideal scenario, there are separate RAID arrays backing the boot volume, video application volume and the SQL storage volume. Again, only enterprise class HDD's should be considered. This scenario presumes that the database will be stored locally instead of a dedicated Database Server. If you are using an external Database Server, you can ignore the Database Volume row.
| Role | Disk Drives | Configuration | Settings | Partition(s) |
|---|---|---|---|---|
| Boot Volume | Two Enterprise Class HDD's any RPM/Cache | RAID 1 (Mirror) | N/A | Recommend single partition with NTFS or ReFS to hold Windows Operating System |
| Video Volume | Two Enterprise Class HDD's any RPM/Cache | RAID 1 or RAID 5 | If RAID 5, larger stripe block sizes (i.e. 64K) tend to give best performance. | Recommend single partition |
Database Volume | Two Enterprise Class HDD's, 7200 RPM/256MB Cache | RAID 1 or RAID 10 | if RAID 10, consider minimal stripe block sizes to improve IOPS | Recommend single partition |
