Is my data transfer rate slow?

[Miklos Botond]

Hello,
I was wondering if the transfer speed on my Hard Drive is slow. I have a 465GB Western Digital WDC WD5000BEVT-75A0R SCSI Disk, which uses a SATA II 3.0Gb/s transfer mode. I know that 3 Gb is actually 384 MB.
I ran a benchmark on the disk using Piriform Defraggler and I got performance report 1.62 MB/s for drive C: and 1.17 MB/s on drive D:
My question is: is this slow, or is this the normal speed?

No thats pretty slow. Try using Crystal Disk Mark instead

OK, so I've defragmented the drives multiple times until there was no fragmentation and my transfer speed grew to 4.25 MB/s on C: and 1.81 MB/s on D:, but I think that is still very slow compared to the 384 MB/s max speed.

I have installed Crystal Disk Mark and run a test with 3 passes using 100MB. Here are the stats:
C: Sequential Read: 69 MB/s Write: 67.5 MB/s
512k Read: 26.8 MB/s Write: 34 MB/s
4k Read: 0.33 MB/s Write: 0.93 MB/s

D: Sequential Read: 57 MB/s Write: 57.6 MB/s
512k Read: 27 MB/s Write: 35.5 MB/s
4k Read:0.12 MB/s Write: 0.53 MB/s

I al.4so did a sequentialt on both drives using 1000MB:
C: Read 77 MB/s Write 74.4 MB/s
D: Read 49 MB/s Write 55.1 MB/s

So is this the speed of my Hard Disk? Is this good enough?

Yes that seems better. I don't really use the Defraggler that much anymore. I use Distrix Ultimate Defrag. Defraggler i use on one of my drives only because i can tell it to put files that are this size or bigger at the end of the disk and what not where Ultimage Defrage does it by how often the files are accessed which I see big performance increases on older PC's but not so much on newer one's.

But yea your drive is a 500GB WD Blue 5400 RPM so yea those 70-80 MBps are more what it should be better. If you have a Black or 7200 RPM drive you will see in the 100 rang. I know my 2TB Samsung 5400 RPM get about 200 (They are in a RAID 0 though so that doesn't really count lol)

Thanks for the info. I will be trying Ultimate Defrag.
