OK just got my C300 64bit this morning from Crucial. Ran Crystal disk mark 2.2 and getting the following connected to my Sata 2 on my motherboard in AHCI mode, I have orders the asus sata card but hasn't arrived yet.
SEQ---274.1---75.82
512k--259.0---75.96
4k-----24.69---15.70
4k
QD32-184.2----38.62
My old Crucial M225 120Gb drive was getting the following:
SEQ---231.4---161.3
512k--163.2---121.5
4k-----27.98---11.98
4k
QD32-184.2----38.62
Atto on the C300 64bg gives:
Max read 286.178MB/s
Max write 79.891MB/s
So the read is better then my m225, but the write is much slower. Once I get my Sata 3 asus card I will check out the max read speed which should be about 355Mb/s.
As I only use about 46GB of my C drive I will be Changing the M225 128GB for the 64GB C300. As I do not write much on my C drive and all my data in on my 2TB HDD.
