Paulu013 ontving van zijn 3ware reseller een mailing waarin de nieuwe 3ware Escalade 7450 en 7850 ATA/100 RAID controllers worden aangekondigd. De 7x50 serie is de opvolger van de in juni geïntroduceerde Escalade 7410 en 7810. Nieuw in de 7x50 is de toevoeging van R5 Fusion Technology, waarmee de RAID 5 schrijf-performance voor grote sequentiële en kleine random transfers wordt verhoogd. Dankzij de R5 Fusion firmware verbeteringen is de Escalade 7810 in staat om met 8 IBM DTLA-307015 schijven een RAID 5 transfer rate van 60MB/s te bereiken:
