What does it mean by 'Fast access drive'?

Do I have to buy anything else to speed things up? (not including SCSI because this thing is very expensive)

Do I have to buy more RAMs?

Is windows 98 capable of holding 10 GB at once? eg only one drive we do not have to partion it.

Thank you for your responses

My Computer Specification
