How important is primary storage deduplication for solid-state storage?
Deduplication on solid-state storage aims at increasing the amount of usable solid-state storage. This reduces the effective cost per usable GB, making it more cost-justifiable when compared with HDD storage. When married to hybrid storage (a combination of SSD and HDD), storage cost per GB can be below that of a pure HDD system.
Ultimately, the importance of primary storage deduplication is in how it makes SSD storage more cost-competitive.
