What type of performance could I expect from a 250gb Seagate SATA2?

My current SATA drive (ST3200826A) gives me these results in HDTach:

ST3200 8mb
86.5MB/s burst
60.9MB/s Av
15.3ms Random access

ST3200 32mb
87.8MB/s burst
61.2MB/s Av
15.3ms Random access

I was wondering what the stats would be on a 250gb Seagate SATA2? (Whatever the latest one is)

It depends on the revision*. So 7200.11 is faster than 7200.3 for example. But if they are the same revision* then performance should be about the same. Also remember that HDTach is not a very good way to test (in my opinion). I think a good test would be to gzip and gunzip a largish file and compare the results. I might just be old fashioned though.

* I don't know what Seagate call it. But their newer models always increase the 7200.x, and have various improvements.

Using HD Tune 2.55 on my gaming PC with my 320Gb SATA2 drive (not 250Gb)

Min: 39.0 MB/sec
Avg: 66.7 MB/sec
Max: 80.8 MB/sec
Access time: 13.0 ms
Burst rate: 117.9 MB/sec

Oh, my SATA2 HDD is running in SATA1 mode due to the mobo.

wilsontc: I'm curious in the performance of the drive I'd be likely to get if I popped down to MSY tomorrow :P I'm guessing that would be the latest.

Jerusalem: Huh, interesting, that doesnt seem all that faster than my current drive. I wonder how much more performance you'd get if it was SATA2.

That drive replaced a dying Hitachi 160GB SATA1 drive. The stats don't seem impressive but the new drive seems faster and more responsive despite the bottleneck.

Running at SATA1 rather than SATA2.

From the statistics that have been posted, I don't understand where the bottleneck is.

SATA is 1.5gbs, which is more than enough for these drives burst rate.

You make a good point. But don't be too sure.

HDTune was reporting that the SATA/150 was maxing out at a real world 116MB/s.

Yeah, but I'd be pretty surprised if a burst speed of 100MB+ is normal. Even if it is, you lose a couple of MB/s. Everybody rush out and upgrade your motherboards now!

It is normal. Run HDTach over your hard drives.

Sorry, I meant in normal use cases, not in some benchmark. I think most people wouldn't notice the difference between even an 60MB and 100MB burst when they're using their PC for typical functions like surfing the web or playing an mp3.

It's a bottleneck, no matter how slight it is. But because it's so small, I'm of the opinion it's not really worth worrying about.
