Synchron Strings - is SSD required?

[batonruse]

Hi and I apologise if this has already been covered elsewhere.

The posted videos for synchron strings and the new synchron player suggest that SSD storage is required. How will it perform using a hard drive (7200 rpm) connected viaThunderbolt 2 ? (unfortunately I can only consider the Standard Library for financial reasons). [iMac 3.4 GHz Intel Core i7 with 32 GB RAM]

Thanks
