X-25M G2: getting low random 4K read/write speeds

[idata]

I'm getting pretty low random read/write speeds on my Inspiron 1720 laptop running Vista and I can't figure out why. Here are my specs:

OS: Vista 32-bit

CPU: Core 2 Duo 2.40 GHz

IDE ATA/ATAPI controllers:

ICH8M Ultra Storage Controllers - 2850

82801 HEM/HBM SATA ACHI Controller

SATA: Generation 1 (150 MB/s)

SSD: Intel X-25M 80 GB G2

Other Settings/Tweaks:

AHCI is turned on in BIOS

Tried disabling Vista indexing

Defragmentation is disabled

And here are the benchmark results:

CrystalDiskMark (Test Size 100 MB):

Random Read (4 KB): 15 MB/s

Random Write (4 KB): 32 MB/s

Random Read (512 KB): 125 MB/s

Random Write(512 KB): 74 MB/s

I've seen others reach as high as 20 - 30 MB/s for 4K read and 60 MB/s for 4K write. I've turned off indexing and deframentation and still no luck. Are there any other tweaks I'm missing? Any help would be appreciated.
