Q: Why doesn’t ASUSTOR offer Hybrid RAID?

2022-03-02


#Hybrid RAID # RAID

ASUSTOR prides itself in delivering a quality experience, therefore, ASUSTOR has chosen not to support Hybrid RAID for a variety of reasons. 
Although old hard drives can be used, if using varying capacities, especially when the difference is large, the age of each drive may vary significantly. ASUSTOR reserves the following concerns: 
- NAS devices are not always filled up. A customer may purchase a NAS and only use some of the available hard drive bays. Since hard drives are purchased at different times, there may be gaps in speeds that could negatively affect speeds when using an ASUSTOR NAS.
- Varying capacities of hard drives mean that the total capacity needs to be divided evenly to match the uneven sized drives. This may also negatively affect speeds and experience on an ASUSTOR NAS.
- Smaller capacity drives often are older and will reach the end of their service life faster. If a hard drive is replaced, the array needs to be rebuilt and can introduce risk with varying capacities and ages.
- A limitation of hybrid RAID is that an odd number of drives cannot be used, wasting the capacity of the leftover drive. 
ASUSTOR recommends to use hard drives of the same capacity to create an array in order to achieve the most efficient utilization.
Retiring or replacing old hard drives? Use MyArchive instead to create hot-swappable archive drives to hold onto old data.
