Is my SSD drive much slower than my hard drive???

Hello,

I bought a new computer: the C: is a Kingston SSD Now S50 32 GB, the E: is a Samsung 1000GB SATA2 7200 RPM, 32 MB Cache hard drive.

The operation system (XP) and my development softwares are on C: so as to be faster.
Immediately on the first day I noticed the if I write any file on C: sometimes there are 3 seconds delay - even at simple thing as putting a break point in Delphi.

Today I downloaded a benchmark software and to my greatest surprise the writing process of SSD was MUCH SLOWER (about 7 times) than the hard drive.
I attached the pictures. Is it a faulty SSD or maybe I configured something wrong?

Thank you

Windows XP is not the best choice for system with SSD disk. You can read this article about differences between hdd and ssd:

Some tweaks can be found here:

May be it is time to go to Windows 7, where SSD drives are supported natively.

A few thoughts ...

Kingston drives are not among the better SSDs, but you should still get better performance than you're seeing ... sequential writes should be in the 50MB/s range.

Kingston has had a couple of "critical" firmware updates for several versions of their SSDs.   Check their site for your exact model # and see if that applies to you.

Are your hard drives running in AHCI mode?    SSDs are particularly sensitive to performance issues if they're not being run in the optimal SATA mode.

Since this is XP, you have no TRIM support.     Are you running an optimization utility for the SSD?   I don't know if Kingston has a utility that's equivalent to the excellent Intel SSD Toolbox, but according to this post Intel's Toolbox will work on your Kingston drive:

Where should I check it? In Bios settings of the motherboard?

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Yes, in BIOS (possible place http://news.metaparadigma.de/wp-content/gallery/efi-x-crashed/efi-x-crash_ep35_01_bios.jpg).
But you will not be able to boot XP after change IDE mode to AHCI.
For Intel controller you can follow:

I have another computer that has Xp with SSD with no problem.

I think I have this problem because my SSD was filled up once and although I deleted a lot of files it "doesn't know" that those block are free again (according to the articles I read).

What can I do? Is there a tool to fix it?
Or what if I install a Windows 7 in a VMware - will Windows 7 fix the SSD to know about free space again?

maybe you can use the intel toolbox, a  suggested in the below thread  :     http://www.intel.com/support/go/ssdtoolbox/index.htm

As I noted above [Post #37338091], the Intel SSD Toolbox will apparently work with your Kingston drive.

It's very likely that is indeed your issue => with XP you need to run a utility periodically (once/month is generally enough) to maintain the performance ... TRIM does that automatically, but XP does not support TRIM.

A Windows 7 virtual machine will have NO effect on the drive -- it will only "see" the virtual drive that the hypervisor creates ... NOT the "real" drive that contains it.

I'd download the Intel Toolbox and run it against your drive.

I download the Intel Toolbox. Almost every button is gray and it says:

SMART Drive Health and SMART Estimated Life Remaining are available for Intel SSDs only.

Is there a way to cheat Intel Toolbox?

Hmm ... I read through the link that says you can use the Intel Toolbox with your drive (I had only posted it before -- didn't read the details).     To use the Intel SSD Toolbox, you have to flash your Kingston drive with Intel firmware (this works because Kingston uses the Intel controller chip).

See the details here:  http://www.overclock.net/t/660723/using-your-kingston-40gb-ssd-with-intel-ssd-toolbox

HOWEVER ... those instructions are for the V series SSDNow's -- NOT the S series that you apparently have.

Bottom line:   I don't know of any workaround for you -- and I'd be VERY reluctant to try flashing the firmware without knowing for sure that it uses an Intel chip.

This is one reason I always recommend using Intel SSDs for any OS that doesn't support TRIM.

The Intel SSD ToolBox doesn't do anything for my OCZ or Corsair SSDs either.

Kingston's SSD Now S100 may have a problem (http://www.tomshardware.com/forum/277517-32-kingston-ssdnow-s100-kingston-ssdnow), and the S50 may also have it.  The performance ratings (up to 130MB/sec read, up to 60MB/sec write) do not sound very impressive.  From what you describe, you need a Secure Erase-type of program to make the drive look like new, but what's going to happen the next time it fills up?

Upgrade your system to Windows 7 and run XP in Virtual Machine. That's should still be faster.

Parted Magic has a secure erase feature (writes zeroes over the entire disk): http://partedmagic.com/doku.php?id=downloads

I contacted Kingston they said it works well only with Windows 7.
I downloaded all the softwares I could find with trim function but no one could handle Kingston SSD

You still shouldn't be experiencing that kind of bad performance with WinXP - here's my OCZ Vertex2 ATTO benchmark.
