HP H8-1234 with Intel 330 SSD - slow SSD transfer rates

[ Edited ]

Please let me know if there isn't enough information here to start troubleshooting. Thanks!

 

I've run the Intel SSD Toolbox and used the System Tuner to disable Superfetch/Prefetch.

I've verified Trim is enabled (DisableDeleteNotify = 0 when queried with Fsutil.)

 

Q: Why are the transfer rates still so low?

 

System Configuration

 

Computer: HP Pavilion HPE h8-1234

OS: Windows 7 64-bit

Storage Device: Intel 330 SSD 180 GB  (Free space: 102 GB)

Port: SATA 0 (HP specs say all 6 SATA ports support SATA III.)

SATA emulation: RAID  (As originally set.  HP specs say this setting provides RAID and AHCI capabilities.)

 

Spec vs. Benchmarked Rates

 

Intel 330 SSD 180 GB - Transfer Rate Specs

Sequential R/W = 500 / 450 MB/s

 

AS SSD Benchmarks

Sequential R/W = 185.45 / 175.07 MB/s (Only 37% / 39% of spec transfer rates.)

 

HD Tune Benchmark

Sequential R = 174.9 MB/s max. (Only sequential read tested; only 35% of spec.)

Hi,

 

When did you first notice this issue?

 

I would suggest that you try a Windows restore point back to when you didn't have the above issue.  Let us know what you find out.  An update to your PC could be the problem.

 

HD Tune should be around 400 MB/s or more using the default settings.

 

I don't know with your particular motherboard if changing to AHCI mode would make a difference. It didn't on my Intel motherboard.

Hi,

 

I was just thinking your HD Tune numbers.  Check the block size under the "gear symbol" then benchmark.  Try it with 256k blocks.  I tried 4k blocks on my SSD the results are not very good. A 256k block puts the performance up around 400 MB/s.
