M4-256 horribly slow

Had the drive now for about 6 months and it has gradually become slower. On an XP machine. Updated to latest firmware a long time ago. About 1800 hours up on it. Did a defrag yesterday (as a last resort) .... took over 45 minutes on a 160 gb partition. It is now slower than the regular drive it replaced. Any ideas why ?? The only thing which seems to run quickly on it is something like 'Duplicate File Finder'.

On XP machine it is possible the partition alignment is not proper - you can check it with AS SSD Benchmark tool.

Take a look below - the second line would be interesting for you

Thank you .... did that ... drive detection failed  ... yet it recognised a USB memory stick. The write on the 4k was very slow (2.5 mins). The write on the 4K-64THRD was very eratic 200's, 300's 750 and settled at about 6. On Acc-Time could not open the device.

You do not need to should not defragment a SSD! 

About he low 4k write performance:Check if the Write Cache is enabled on the drive.

Re: M4-256 horribly slow

According to your first screenshot there were no need to align the partition - you can see this green information "0 K - OK" however I am not sure is it proper or just some glitch like your noname empty drive with no firmware and unknown ahci driver. 

 

Anyway pictures are moderated so we have to wait a while before we see them. You can link your screenshots with other media hosting service like http://imgur.com/ or http://imageshack.us/

Definately a glitch. It can't be 0k :smileyhappy:

I can see the second screenshot now. Benchmark looks quite okay so you should see performance increase now. Apparently the partition was not aligned correctly before. No drive information can be caused by some untypical motherboard or storage driver but in case it works with no other issues I would probably leave it as it is.

All partitions needed to be aligned and the readings are much better now .... and loading much quicker too. I am much wiser now. Thanks to all for input and help.
