High HD Tune numbers are they real?

[hectorsm]

I've replaced my two old 500GB Hitachi drives with two 1TB WD black (in RAID 0) and was surprised to get such a high number in HD Tune. I'm happy with the numbers but I was wondering if they are real. I'm using a X58 chip set that only supports SATA II 3gbit/sec. Here is the screnshot:

Never seen scores like that before. What do you all think?

Those seem normal RAID 0 speeds.

Buy an SSD then you'll be far less impressed with those results. LOL.

I really do not trust HD Tune to begin with much these days myself personally.

The free version is old and My RAID0 SSDs get a lot different test results these days, even when I was using many Raptors and was getting over 500 years ago.

Maybe it's just my Windows version, the old one does not support 10 it looks.

They test a lot higher on other programs than what HS Tune shows these days, I just dld it to try it out again not long ago with the SSD's and a SATA 3 card.

For a Black that probably isn't far off though. Looks about normal.

Those are sequential numbers. You can also see that your access time is 12.7ms. This is what really matters, and that's where SSD's shine.

The reason I asked is because my previous two RAID 0 setups had a much lower sequential read (150mb/s and 200mb/s). This setup is a lot faster.

I did a little research and found that these drives are single platter 1tb drives so they have a very high areal density. Maybe that's why I got such a large jump in the number. I also thought my SATA II interface will be saturated but it is not. If I convert 3 Gigabit/sec to MB it will be 375MB transfer limit. I know that sequential transfer won't translate in to real world but it's good to know I have not reach the limit yet.

I'm planning to build a new system in a year or two so an SSD is a possibility. I need 2tb as a minimum in my boot drive and the current prices are too high and my motherboard will be holding it back.

RAID0 doubles your sequential I/O and random IOps with multiple queue depth. So the numbers look fine. The fact you have SATA/300 does not mean you cannot go beyond 300MB/s, since you are using multiple SATA interfaces. Using two disks give you the maximum of 600MB/s bandwidth (in reality about ~520MB/s throughput). Harddrives are not that fast, however, so 2x 150MB/s seems reasonable.

Do note that harddrives tend to be only half as fast at the end of their capacity, compared to the begin of their capacity. You can clearly see this in the HDtune screenshot you posted. The numbers look fine to me.

My 6 disk velociraptor set up in raid 0 does an average of 886 mb/sec and 5.4 ms seek time

I hope you like data loss.

I hope you like data loss.

Been running this way for over 3 years now and all my files are backed up weekly......thus never worry about data loss.
