Patriot Warp V2 SSD on a Macbook in Vista (Part 2)

This is a follow up to my previous thread. I did a full installation of Vista Ultimate on my Macbook in a Bootcamp partition. I did all the windows updates, but did no tweaking. This a fresh, stock inatalltion setup.

I ran ATTO (picture attched) and HD Tune (picture attached). I also ran 10 tabs of youtube videos in IE, while running HD Tune (picture attached).

I did a bunch of various activities as well, taxing the cpu to near 100% and suffered no random slowdowns. I played with this for about three hours straight and never felt any slowdowns (except when the CPU neared 100%).

For me, this drive has been awesome!

 

Nice.. What block size are you using in HDTune? Can you test it with a larger block size or is it not an option in your version? very nice performance, though it does not hit Patriot's claimed speed. However, if it doesn't stutter, that is by far the most important part

 

Awesome, Cant wait for my 64gb one!!
Btw it seems that the reads are slower in vista with your macbook.

 

I don't know. I just did the default test. I can certainly give it a try later. What size would you like to see?

 

Anything over 256kb would be fine . Maybe 1mb just to see if Patriot can reach their claimed speeds?

 

Attached.

 

I see. Thanks for running . It definitely owns any hard drive with that, but it still doesn't meet it's claimed 175 . But hey, most importantly, it's not stuttering or doing anything stupid like that

 

Nice to see an "affordable" ssd which isnt flawed to the point of unusability.

 

So, thought I'd stop being lazy and actually screen capture the same benchmarks with my patriot V.2 32GB. Yes, it can be made to stutter, just like any of the other SSD's with the jmicron controller. Tests are done with a desktop system with 965/ICH8 chipset under XP SP3, and it's a secondary drive. I'm guessing that the majority of the differences in results are just due to the rest of computer hardware, would be rather disturbing if there was that much difference between the performance of the different capacities.

 

so what is the final word ... is it still getting those 2-3 second delays from time to time ?

 

miro:

There are many variables. One of the items that seems to be a dependency is whose chipset you're using.

I will post some results sometime next week after I get my 32GB up and running with Vista on my HTPC.

 

I've got .. uhh .. 965M .. I think. It's Lenovo T61

 

Mine does not seem to at all. I have simply been unable to get it to studder, no matter how hard I try.

It is my understanding that the v2 Patriot drives have an optmized firmware to deal with the studdering phenomena.

 

Well, purrhaps sometime I'll have to play around with a copy of Vista. I didn't notice any issues with either an OSX install or Ubuntu, but didn't test either extensively. Windows XP, however, something so simple as repeatedly opening and closing IE7 could occasionally get a slowdown to occur - it's all about having some small writes to the drive occur. One way to artificially force that condition is to do an IOmeter run with 4k random writes. Doing so on the V.2 install and then attempting to open/close internet explorer repeatedly eventually averaged to about a 20 second wait between clicking on the icon and it actually responding, the UI basically wouldn't respond to inputs. Doing the same thing on a Samsung F1 resulted in maybe an extra second worth of pause compared to normal times.

This all really tends to point towards some amount of the pausing issue being the OS used. Basically the patriot V.2 still has pathetic random write times, but if the OS plays nice then they can mostly be masked from the user. XP doesn't seem to play nice.

 

That's pretty amazing. It's just like this guy: http://www.youtube.com/watch?v=7gPcGb_Hdyg
He has no sutters with his on Asus 1000H and Vista.

Rogue how large is your first partition?

 

95gb for Mac OS X. 25gb for Vista.

 

I noticed that you mentioned Ubuntu. What was your experience?

I tried to run zcav and some test with dd on Ubuntu, and my WARP.v2 seems to be limitied at 125 MB/s throughput. I guess it could be some due to some configuration issues.
This was run on a Abit IP35-Pro motherboard with the ICH9R in RAID mode.
The WARP.v2 is not formatted yet.

Here is two plots, first is showing the full graph up to the 750GB limit on my data drive, and the second shows just the first 32GB to compare the drive in the optimal region.
