I'm making an eSATA boot drive for my Macs using an OWC usb 3/eSATA III enclosure with a 2.5 inch form factor. Seems to be the only enclosure they have with both connectors, which I need since my Mac Mini does not have eSATA. The 2.5 inch size limits my choice of SSHDs to 5400rpm as far as I can find. Typically a 1TB (5400 rpm) SSHD has 8GB NAND.
Will the slow rpm drive really perform close to SSD speed and is rpm not very significant in a hybrid drive? How much faster will a 7200rpm SSHD with 8GB NAND be than a 5400rpm with 8GB NAND when used as boot drives?
Looking at it from amount of NAND perspective, at the same rpm would 32GB NAND be much better than 8GB for boot drive? Would a 5400rpm drive with 32GB NAND likely perform better or not as good as a 7200rpm drive with 8GB NAND?
