Force 3 read speed dropped

[Tom_92]

Hi there, I recently noticed that my boot time suddenly increased from about 8 seconds to 20 seconds so i checked the read speed on my force 3 and it has dropped from original from 550 mbps to 308mbps. I have ahci and trim enabled and disk fragmentation is turned off, sometimes the boot speed drops back to 8 seconds would appreciate your thoughts. Just wondering what might have caused this or if its a fault, or would updating the firmware help?

 

Thanks for your time

I have about the same setup as you, do you have your SSD hookup up to the AS Media ports on your motherboard that is where i had mine and my speeds were about 300mbps when I used the intel SATA ports i got the 555 mbps, now i have a raid config and get over 1000 mbps :)

i got it in the intel sata 3 port, i take it thats what you mean ?

What programs are you using to measure performance.

 

In-compressible data (AS-SSD and Crystaldiskmark with random data) perform a lot slower on the standard corsair force 3 (with async nand) in both read and write scenario's.

 

Highly compressible data (Cystaldiskmark with 1 or 0 fill, and ATTO) generally performs at full SATA speed (or close to it) on all sandforce based drives regardless of size or NAND type. Edit: Note that Corsair specifications are based on the highly compressible data benchmarks, so if you are comparing your in-compressible data benchmark to them, it will seem your drive is very slow in comparison.

 

But all the above said, your slow boot issues are likely nothing to do with the SSD, and either a software problem, or a network induced delay.

I do know that my external hard drive slows down my boot as it spins up the drive, probably a bios thing to see all the drives before actually booting. Did you run ATTO to see your drive speeds?

i used command prompt to test the speeds, whats atto ?
