I am trying to expand the capacity of our exchange server, right now it is running on Raid 1

Fujitsu MBA3147RC 147GB 15000 RPM 16MB Cache Serial Attached SCSI (SAS) 3.5" Internal Hard Drive -Bare Drive

I would like to change it to either

Seagate Constellation ES 1 TB 7200RPM 6 Gb/s SAS 64MB Cache 3.5 Inch Internal Bare Drive (ST1000NM0001)


WD Red 1 TB NAS Hard Drive: 3.5 Inch, SATA III, 64 MB Cache - WD10EFRX

I am running these on old hardware so it's only capable of 3GB/s, which is why I am not getting high end SAS drives.  

Capacity wise it is more than what I need, I am just wondering what the performance impact will be. These drives are slower but I am wondering if it will be more than enough to handle an exchange server of 50~ users. Any advice or alternative suggestion would be greatly appreciated, thanks.
