Is a RAID enclosure merely a place to put your hard drives that are connected to your controller and provide hardware (as opposed to software) RAID? They seem so expensive I was just wondering if that was all that they did.
Also, this product has the following specs:
2.5" Drive Bays 25 x 300 GB 6G 10K SFF Dual-port SAS
Does that mean it won't support a hard drive whose capacity is >300GB (ex. 450GB SAS) and it won't support hard drives whose rpm is >10k (ex. 15k rpm)?
