Is a Mobile Rack can be a bottle neck for a hard drive?

[HardwareSeeker]

Hello, All,

I’m looking to buy some Western Digital 500GB RE2 hard drive (Model #: WD5000YS). This hard drive has a 3.0 Gb/s data transfer rate. I’m planning to set up 4 of those disk in RAID and I was thinking to us a swappable case to puts them in.

I was looking for the Vantec EZ Swap MRK-200ST-BK Mobile Racks.
The concern that I have is the hard drive spec. a 3.0 Gb/s data transfer rate and the Vantec Rack spec. a 150MB / sec.

Based on that, the rack will bottle neck my hard drive no?

Am I wrong or what I’m missing something?

Thank you,

No, the rack will not bottleneck your HD. The 300MB/s for the HD is a theoretical max, the speed usually never breaks 100MB/s.
