Vaio Z + ssd Intel x25-m. Poor performance.

Installed in my Vaio VGN-Z11XRN solid drive Intel X25-M. In all tests it shows one of the best performance results. It should read up to 220mb/sec and write 70mb/sec. But not in my machine

Bios: hacked R4043
Drive firmware: 2CV102HD
ACHI mode is set.
OS: Windows7 x64

In my case I can see just 150mb/sec maximum.
Where is the bottleneck ?



Tried to test in my stationary comp. Intel P35 in AHCI mode. Read speed was about 200mb/sec

 

Check device manager to see what UDMA your SSD is running.

 

Here:

 

From the benachmark it looks like you have only SATA 1.0 (150mb/s).
Maybe a bad implementation of the interface?

Have you tried other tools (AS SSD, ...)?

 

I cant get information what exactly interface it is using. But the next screenshot tells that sata 2.0 is used.
Here comes AS SSD benchmark. It is very strange too




And CrystalDiskMark 2.2:

 

Isn't HDTune useless for SSDs? As far as I am aware it is.

By the way... why on earth did you partition your SSD?

That's a stupid thing to do, especially on a small one like yours.

The Intel SSD (and they are good) will only perform at maximum performance if less than 80% are in use - hence a single partition should give you more free space overall and allow for better speeds.
On a HDD you had the speed benefit of the first partition - you don't get that on a SSD.
And depending on which partition you use more, you'll wear out some parts of the SSD out faster than others - I don't think wear levelling works across partitions.

 

About HD tune you are right. But only old one. New version gives completely another results.

I have never heard about that. Maybe you can link a source?

 

Well it was mentioned in the SSD thread many times. You better ask there.
