Hi guys,
I decided to run some performance tests on my SSD only to be disappointed by the slow write speeds reported by the software.
Pictures of the tests below:

Crucial M4 SSD 64GB (FW 0309) - With OS (Windows 7 64bit installed) ~50% Full

OCZ Vertex 2 SSD 120GB (FW 1.35) - With some programs ~5% Full

Seagate Baracuda 500GB 7200rpm HDD - music, pictures, etc. ~50% full

so my question is: Is this normal and if not what can i do to improve it?
SSD's health statuses are both on 100% and I had ACHI enabled before i installed Windows.

Help is appreciated.
Thanks
 
Something's not right... try thr ATTO benchmark and see what you get: http://www.techpowerup.com/downloads/1749/ATTO_Disk_Benchmark_v2.46.html

On the other hand, assuming it's the system in your sig, your board uses these chips for the SATA ports:

Chipset:

6 x SATA 3Gb/s connectors (SATA2_0, SATA2_1, SATA2_2, SATA2_3, SATA2_4, SATA2_5) supporting up to 6 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, RAID 5, and RAID 10

GIGABYTE SATA2 chip:

1 x IDE connector supporting ATA-133/100/66/33 and up to 2 IDE devices
2 x SATA 3Gb/s connectors (GSATA2_0, GSATA2_1) supporting up to 2 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, and JBOD 

2 x JMB362 chips:

2 x eSATA 3Gb/s connectors (eSATA/USB Combo) on the back panel supporting up to 2 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, and JBOD
2 x SATA 3Gb/s connectors (GSATA2_2/GSATA2_3) supporting up to 2 SATA 3Gb/s devices
Support for SATA RAID 0, RAID 1, and JBOD

Are your drives connected to the native Intel ones?
 
M4 64gb writes blow in sequential, 128gb is better but still not close to the 256gb versions performance.

Vertex 2 should probably be giving better performance however Sandforce's huge speed comes from compressible data, AS SSD only benchmarks incompressible data, Sandforce based drives look way slower in writes in that benchmark than say Atto.

Run the whole benchmark as it will give a much clearer picture of performance, and also much clearer difference with the HDD.

Don't compare it to a hdd in just sequential, the BEST ssd(non pci-e one) is maybe 3-4 times faster than a hdd in sequential, the worst ssd's(3-4 years old) are magnitudes faster in random read/write performance and ridiculously faster in access latency.

Its the random read/writes, the iops and the latency that are the huge difference between hdds and ssd's.
 
Thanks guys.
I think i was mistaken when i thought the M4 had higher writes so that's fine.

Also with ATTO the Vertex in much quicker so i'm happy.
Just posting the screenshots in case someone is interested.

First one is the M4 and the second is Vertex 2
