"Erste Muster der Chips will SandForce noch im zweiten Quartal 2009 ausliefern und zudem darauf basierende Referenzdesigns anbieten. Noch in diesem Jahr sollen dann auch SSDs verschiedener Hersteller auf Basis des SandForce-Chips auf den Markt kommen."
Fakt oder Fiktion:

- angeblich 80-fach längere Haltbarkeit gegenüber Standardcontrollern
--> 24h/7 Tage Einsatz von MLC im Businessumfeld möglich
- kein DRAM Cache notwendig
- nahezu keine Performanceverluste über die Zeit
- internes RAID gegen Ausfälle von Flashblöcken
- hochqualitativer Error Correction Code Mechanismus (theoretisch 1 Fehler in 3,6 Jahren)
- interne Datenverschlüsselung ohne Geschwindigkeitseinbußen
