Why would the architect make this decision?

25. An organization plans on building their own cloud solution and is designing a new storage environment with the following requirements:

• Current IOPS = 25,000

• Expected growth rate = 100%

Storage vendor specifications:

• Max storage blocks in a storage system = 8

• Max number of drives per storage block = 24

• Max IOPS per HDD drive = 180

• Max IOPS per SSD drive = 450
