I recently bought a Seagate 500GB (ST3500320AS) SATA drive. I was reading its specs from Seagate's website and they had the following:
Interface - SATA NCQ
Cache - 32 MBytes
Capacity - 500 GB
Guaranteed Sectors - 976,773,168
PERFORMANCE
Spindle Speed - 7,200 rpm
Average latency - 4.16 msec
Random read seek time - <8.5 msec
Random write seek time - <9.5 msec
I was doing some benchmarking with the latest freeware versio of SiSoft Sandra and these are my results:
Benchmark Results
Drive Index : 78.21MB/s
Results Interpretation : Higher index values are better.
Random Access Time : 12ms
Results Interpretation : Lower index values are better.
Performance Test Status
Run ID : ST3500320AS 500GB (SATA150, NCQ)
Platform Compliance : x86
System Timer : 3.00GHz
Use Overlapped I/O : Yes
I/O Queue Depth : 4 request(s)
Block Size : 1MB
Volume Information
Capacity : 465.76GB

Speed at position 97% : 50.52MB/s (49%)
Speed at position 100% : 46.74MB/s (45%)
Random Access Time : 12ms
Full Stroke Access Time : 9ms
Physical Disk
Model : ST3500320AS
Version : SD15
Interface : SATA
Removable Drive : No
Queueing On : Yes
I'm comparing the Random Access Time number with the specs on the website. It's off by a couple milliseconds. Is there any way I can improve on this?
My 500GB drive is connected to its own SATA port on the motherboard, and it's solely use for storage purposes. No applications or programs reside in it.
Thanks!
