Can you daisy chain 2 R4s and have read/write speeds similar to the R8?


Thanks in advance

Hi Jimmy,

Thank you for choosing Promise Technology for your storage solutions.

You can daisy chain the both Pegasus2 R4 units, each Pegasus unit shows as a separate volume on the Mac Pro. Each Pegasus unit mounts as a separate raw disk volume on the Mac pro. Moreover, Pegasus series units are direct attached storage, where you can connect each unit directly to a Mac system and mount the volume then use it. The performance will be calculated separately for both units. Unfortunately, it cannot be combined as a single volume to calculate the performance.
