Hi Shaun
I have also found big speed increases in ply reached and Kn/s when testing my HDD v my 8GB Corsair Voyager GT. (When using complete 5 man)
On average a 40% higher Kn/s rate acheived when using the flash compared to HDD. (In test postitions with 6 or 7 remaining men)
Regards
Darrell

I just carried out a quick test on the position you gave in your link.

Using Fritz 10 with 256Mb hash and 32Mb tablebase hash and using infinite analysis mode for a 3.00 min think.
Here is the analysis outputs, first is with complete 5 man TB on my flash drive, second is with the complete 5 man TB on my Seagate 750Gb drive.

As you can see the flash setup completed the 21/53 depth search in 1:19 mins compared to the HDD of 2:32 mins.
I noted on watching the Kn/s the flash setup was allowing Fritz to run at 1300 - 1400 Kn/s compared to the HDD setup of around 700 Kn/s.

As you can see the flash setup completed the 21/53 depth search in 1:19 mins compared to the HDD of 2:32 mins.
I noted on watching the Kn/s the flash setup was allowing Fritz to run at 1300 - 1400 Kn/s compared to the HDD setup of around 700 Kn/s.

I like more if you test FLASH verus Western DIGITAL RAPTOR 150 or 74 GB, that are HDD 10.000 rmp. and are very fast to read files IO...
I have raptors, but not have Flash
you have flash, but not have RAPTORs...

I have also found big speed increases in ply reached and Kn/s when testing my HDD v my 8GB Corsair Voyager GT. (When using complete 5 man)
On average a 40% higher Kn/s rate acheived when using the flash compared to HDD. (In test postitions with 6 or 7 remaining men)

thanks for your results - the more the better!!!

Sorry no Raptors here , although I suspect flash would still outperform a single Raptor, and for TB access write speed is not an issue...KarmaZen&Oliver wrote:

I have a new flash drive in the post - once that arrives I will run some additional tests.
Now if someone had both a fast Raid array and flash we could do with some more results

Hi Harvey,Harvey Williamson wrote:Hi,
These tests are interesting. I have just been experimenting with changing tablebase depth for Hiarcs from the default 2. I have tried 3,4 & 5 has anyone else experimented with this?
Best Wishes,
Harvey
Hiarcs seems already very aggressive with its TB access as can be seen from the graph.
For 5men TBs I think flash is a must but it must have fast random read.
For 6 men a combination of flash and fast raid would probably be optimal.
One thing I am glad is that nodes/sec holds even though time to ply does not when running 2/4 threads.
I will also run the node counts without TB for an additional comparison, my guess is that slow TB access could impact performance more than not having the TBs - however a lot of games would be required to prove that.
Once I have any more info I will post here.
Shaun
P.S. Good luck for Leiden

Re: Hiarcs TB test - HD v Flash
It isn't so interesting since it is really biased toward the flash drive. 7200 rpm drive (non-SCSI) are not known for high-performance.Shaun Brewer wrote:You might find this post interesting

Hi Harvey,
A nice flash drive - it may be faster - the price put me off - I think this drive is similar for TB access but write is slower and seems a little flimsy but should be okay for TBs. I am going to buy a second one soon.
Am I correct in thinking you have raid on a couple of your machines???
Any chance you could run a couple of test with the position I used (5 men only) with raid v flash - I can then add your data...

A nice flash drive - it may be faster - the price put me off - I think this drive is similar for TB access but write is slower and seems a little flimsy but should be okay for TBs. I am going to buy a second one soon.
Am I correct in thinking you have raid on a couple of your machines???
Any chance you could run a couple of test with the position I used (5 men only) with raid v flash - I can then add your data...

I do not use Raid on any of my machines so am unable to test this.
