<div class="moz-cite-prefix">Two little things:<br>
<br>
1. I think we all mean 7.2K drives - 7.5K drives are quite hard to
get, as they don't exist. :-)<br>
2. There are 2 types of 7.2K drives - nearline SAS and SATA.
There's very little to split these in terms of performance, but
depending on the server they're being shoved into, a nearline SAS
device may have better connectivity to the backplane (and
shouldn't require a pesky interposer).<br>
