ECDIS SSD must be replaced regularly.

We tested the JRC ECDIS's SSD CDD-753 / CDD-753A which had been used 5 years, and ECDIS cannot start up to normal after black-out.  Tested the CCU in workshop, found its SSD Wear Cycle more than 3000 P/E Cycle Limitation， reach 5697 .  ECDIS system unable to operate and unsafe to navigate. 

We strongly recommend to replace NEW SSD for JRC CCU NDC-1590A / NDC-1590 which installed in JMR9210/JMR9225/JMR9230/JMR9282/JAN9201/JAN9202, 

there are 2 pc.s of SSD in the CCU and the SSD type is CDD-752A and CDD-753A.
