This is my system specs-

System Manufacturer: Hewlett-Packard
System Model: HP Pavilion dv5 Notebook PC
Motherboard Manufacturer: Quanta
Motherboard Model: 30F2
Currently Installed Memory: 8GB
Processor: AMD Turion(tm) X2 Dual-Core Mobile RM-70
Video card : ATI Radeon HD 3200 Graphics

I have installed the 256gb Crucial M4. CT256M4SSD2. And it came with the latest firmware preinstalled. 00F.

My BIOS has NO settings to change between IDE and AHCI. So I don't know what to do about that.
I have disabled Superfetch. Drive indexing and defrag.
The OS was a clean installation. (win 7 x64)

and am getting really really low numbers here. I'd appreciate any help that I can get. I'm a n00b so go easy on me.

Without knowing your laptop specs, i'd say that looks like it's locked into IDE mode on SataII.

It looks ok, and tbh, if it is locked to IDE/SataII then that's the best you'll ever get.
 
Check the info and it says 'msahci' so I assume it's configured in ahci mode, would also guess that the mobo only has SATA II and that's the reason for the slow speeds (although it should still be rapid compared to the prvious mech drive).

I did have the AHCI mode. It said so in the device manager.

Then today I downloaded the following file and installed it -

and now the information in my device manager has changed to PCI ide controller. :eek::eek::eek:

and my AS-SSD Benchmark figures have Improved??!!! :confused::confused::confused::confused:

What's happening?
 
Achi mode is just a little faster and enables TRIM, so your drive will maintain the best speeds over time.

As for the lower-than-should-be sequential read/write, it's because your laptop must only support SATA II, so it's limited to 3Gb/s or 375 MB/s, but that's a theoretical limit, so the practical limit is more like ~270 MB/s
 
The speed is not an issue.

Everything will still run faster than before, the only thing you'll really miss out on is been able to see high numbers in benchmarks.
