Mobile Rack for a hard drive and speed concern

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?

Thank you,

You are leaving out an important bit of info. The rack you cite is a SATA I rack. Therefore, I must assume your HDD is also SATA. If you want the same transfer rate (SATA II) you have to use a SATA II rack.

the specs are theoretical. in reality the hdd will max out at most 70MB/s str so you will be fine eithe way. unless sataII offers some other features not found in sataI all will be the same.

I doubt these racks have any electronics between your data cable and your drives that would interfere with a "SATA II" data rate, even if they aren't rated at SATA II speed. The drives and the controller cards are where you'd have a bottleneck. IF you actually could transfer data at "SATA II" speeds. Which you likely cannot, even with the fastest RAID 5 SATA controller card.

Some of the latest SATA-300 drives might be able to burst at over 100MB/sec. so a sataI rack may cause the drive not to work at SATA300. To be safe, I'd set the drive to SATA-1 when mounted in a SATA-150 rack.

If there is empirical data to the contrary, I'd like to see it.
