Show us your SSD performance

[nate42nd]

I have never seen a performance graph like this. Besides the slow average, the ups and downs are not normal. Maybe it is an alignment problem. Check the alignment (in msinfo32 > Components > Storage > Disks > Partition Starting Offset - for the first partition).

here is the info

I'm not sure what's going on here, but something is wrong. I will start looking for what would cause this. If I can find out I will let you know. This isn't normal at all.

MSAKSA, the alignment looks fine.

Thank You

ok what's wrong then?
do you think that I need to replace my Mother Board??
we can keep discussing in this thread

thanks all

To tell you the truth, I do not know what's wrong. The mobo is the most unlikely culprit. It could be the firmware or some setting in the BIOS. It may also be wise to run the test with another tool - e.g. Everest Disk Benchmark. I have seen a lot "smoother" read results of the same disk with that - e.g. here.

Hi all,

I just ran this test this evening. My system is as follows:

Windows 7 Pro x64, clean install
FireFox v3.6 x86
ZoneAlarm Extreme Security v9.1.008.000

Intel Core i7 920 with stock cooler
Intel X25-M 80GB SSD G1 x 2EA in a RAID 0 configuration 128 KB stripe
ASUS P6T Deluxe mobo with OC Palm Remote (BIOS 1102)
Corsair Dominator 6GB (3 x 2GB) TR3XG1600C8D DDR3 1600
Cooler Master 700W 80 PLUS SILVER Certified PSU
EVGA NVIDIA GeForce 9800 GTX+ (G92) 512MB 256-bit GDDR3

Anyway, here's what I got.

i ran into some problems with my ps-100. so i rushed out and bought a new kingston ssdnow v series 64gb. it works well for me and since i've had it, it has been very stable and steady in its performance--not as fast read speeds as the ps-100 but consistently better write speeds. i'm sending the ps-100 to patriot for rma

because i rushed out and got this, i didn't do the necessary homework on it first. i found out after the fact that this is sata 1.5

but, as i stated, the performance has been stable and steady--no complaints.

 

[mpcrsc562]

after i was given the tech reference # from patriot, i was told in the email that the # would be valid for 30 days. so, i took the time to give the disk one last chance. on my daughter's computer, i imaged her vista installation and installed it on the ps-100. everything was very good (that was approx feb 22). i performed a bench on it this morning (atto) and the highest read speed i got was ~37000 . needless to say, i'm going to get started on the rma process over this weekend (after i find a replacement for this drive).

the kingston drive referenced in my previous post was purchased to replace the ps-100 for my windows 7 installation. as stated, flawless operation thus far.

when it's all said and done, looks like i'll be having a spare ssd laying around (the ps-100 once i get it back from patriot). i guess i'll put it to use on my xp machine in the garage... it's a little too expensive and small in storage size to be used as an external drive . oh well.

One thing I do not understand though is why my "burst rate" dropped so much.

One thing I do not understand though is why my "burst rate" dropped so much.

I think the Burst Rate test (whatever it does) is flaky sometimes, particularly on SSDs. I've had it vary by as much as a factor of 2 in tests run in succession. Maybe it occurs so quick on SSDs that if the OS happens to be starting something at that very moment, the OS sucks up the bandwidth. On regular drives the results may be evened out because of the smoothing effect of the (relatively) longer period of time it takes to run on them. Who knows.

Great performance, by the way.

Well I'm back, it only took me a month to get my drive and install it. However as you can see my numbers are less than stellar compared to the other Intel drives posted here and I believe that my issue is the dreaded alignment problem (I guess cloning the drive was not the way to go). So I have another question, if I reinstall Windows can I then take my system restore image and just put everything back at one time or am I going to have to reinstall everything individually in order to keep it all "aligned". Thanks in advance for your help.

Tom

BTW Where do I have to stick the english dll (be nice) for the benchmark to find it.

Trick to clone an unaligned partition and align it

I came up with a trick to clone an unaligned partition into an aligned partition. I wanted to run Windows Home Server on an OCZ Vertex and with WHS there isn't the luxury of reinstalling and have the installer properly align it like in Vista and W7.

So I created the smallest partition possible (8MB) on the Vertex using Windows 7, leaving the rest of the drive as unallocated space. The 8MB partition was aligned and the starting partition boundary for the unallocated space was also aligned. Then I cloned my WHS install partition to the unallocated space. I've used both Acronis 2010 and Partition Magic free for this. On two eSATA docks, the 3GB clone took only a couple minutes. Now my cloned WHS OS partition is aligned. I deleted the 8MB partition, marked the cloned OS partition active and now the OS is the "first" paritition on the disk and bootable. Put it back in the WHS box and it worked like a charm... WHS running on a 30GB Vertex (installing WHS to a drive less than the required 75GB was a whole 'nuther trick).

For your system restore image, maybe creating the "dummy" partition will solve that alignment problem too.

Hi zrtom

While I appreciate your fast reply to my dilemma, unfortunately you are way beyond my ability when it comes to Windows 7. I was barely able to do this the first time and have no experience with either of the programs that you mentioned. Unless you want to drop by to help I really need an answer as to whether or not I can reinstall and restore the drive. Thanks again.

hi, i had the same problem with my intel 80GB, what really help me was this guide.

How to setup Core V1/2, Solid, Apex, Vertex SSD with aligned partitions using USB (if available on the drive) or SATA. Updated to show how to use Vista recovery disk

then once i had the alignment, i just used Acronis and cloned my windows 7 64bit over..
works perfect.

he also made a video on how to do it. http://www.youtube.com/watch?v=tUu9InlfD_c

 

[b00bie]

Hi

If I follow this can I use my current windows restore image or MUST I use Acronis. Thanks.

Tom

 

[whs]

You are probably better off with an Acronis clone because that can adjust to the disk size.

 

[b00bie]

Forgive me for being so dense but after looking at the link and watching the video, I am still confused. It appears that the drive has to be a spare drive, so that means that the SSD has to be moved to a different SATA connection and I have to put back my old drive to make the clone from and boot from that drive to accomplish this. Can someone just explain it to me VERY SLOWLY as to why reinstalling windows on the SSD and allowing it to reformat the drive to the proper size and then restoring it from the restore image will not work. Quite frankly I don't have the confidence that I can accomplish the currently outlined method and might just live with what I have rather than screw it up completely. Thanks again for your patience and help.

Because

Window's 7 backup and other backup programs image the whole drive, including the free unformated space before any partition. By alignment, it means that you are creating your first partition after the 63rd sector or the 1023rd sector or any other setup that makes it aligned. The point is there has to be a predetermined amount of free space before the fire partition to ensure that it is aligned.

If you were to simply reinstall windows, it will not delete any existing partition but will just install itself on the already misaligned partition. Misaligned means it's not starting at the proper sector.

If you were to delete all the partitions, then reinstall Windows, it will create a partition for you, which will be aligned and it's fine until there. But when you restore the image, it will restore the whole drive back to how it was before. It doesn't matter what partitions you've already aligned on the drive.

Alignment refers to the position of a partition, not some physical property of the drive. So when you restore restore the image, you're restoring one or more of the misaligned partitions back to the drive.

Now you could back an image of just the misaligned partition and attempt to restore it onto an aligned partition. The success of this depends on how the backup program works. If it simply write the data bit to bit in order on the new partition, then it stays aligned. But if it deletes the partition and creates a new partition to write the image on, it depends if the software creates the new partition aligned or not
