Read the letter immediately after CECH. Your PS3 was made before October 2007 if the letter is A, B, C, E or G. These PS3 models have 256 MB NAND memory. If the letter is H, J, K, L, M, P or Q, your PS3 has 16 MB NAND memory. If a number appears after CECH, then it is the serial number of a PS3 Slim, which has 16 MB NAND memory.
