Barracuda V Performance
Barracudas are very fast, at least in their native habitat, the ocean. Seagate's Baracudas have an equally fast reputation but we are stuck here with a preproduction engineering sample that still may need some tuning to deliver optimal performance. When we received the drive from Seagate, we had to promise we would not run any benchmarks or at least not publish them. Well, we lied ..... Let the games begin!
Test Configuration

To match the drives size differences, both drives were partitioned with a 3 GB primary DOS partition and a separate swapfile in a 1 GB logical drive on the Extended DOS partition.

HDTach
We start out with HDTach to get some basic information on the drive. The sustained transfers are quite impressive and about the same level with the IBM 120 GXP Deskstar but we are missing the 150 MB/sec transfers that the drive should theoreticlally deliver. Keep in mind that the transfers will be capped by the 133 MB/sec limitation of the PCI bus. Most likely, with some more tuning, we will see some higher burst performance in the near future
As we emphasized earlier, HDTach is similar to SiSoft Sandra, just streaming through the platters does not necessarily give any indication of the real world performance of a drive. So once again, we resorted to our all time classic: WinBench98 to check what is really going on.
