I just built a complete new computer including a motherboard with SATA 3 ports and a brand new 2 TB harddrive 7200RPM, 64mb cache, and Sata 3 capable.
I'm working with some large files and it's taking FOREVER.
I pulled up the Windows performance monitor and during transfers, disk activity hovers around 6-8 MB/sec Disk I/O.
Is this normal? I seems way too slow.
I've never done much relevant HDD troubleshooting so I'm not sure what information about my setup is relevant. If you need more information, please comment and I'll update it.
I ran CrystalDiskMark at 100MB and got the following results: (Read/write)
Seq 208.6 181.2
512K 75.70 143.9
4K 1.123 1.318
4k QD32 1.820 1.137
Also possibly worth noting, I installed the Seatools utility that came with the drive and it does not seem to detect the drive at all.
What do you mean you're "working with some large files"? What are you doing with the files? Are you accessing some of them in parallel maybe? – Breakthrough – 2013-03-08T03:11:11.320
Converting video files. – cody – 2013-03-08T03:11:35.353
1when you're converting video files, I wouldn't expect to see much higher than that. How many FPS are you encoding at? Encoding is primarily CPU/RAM bound. – Breakthrough – 2013-03-08T03:12:50.240
According to performance monitor I'm below 8% CPU usage and below 50% memory usage. 30 fps file – cody – 2013-03-08T03:14:34.637
How many FPS does your encoder run at? – Breakthrough – 2013-03-08T03:15:30.923
I'm not sure, where would I look for that info? – cody – 2013-03-08T03:16:02.967
Put it this way cody. If you copy a large file, what transfer speed do you get? (make sure nothing else is using the disk when you do this) – Breakthrough – 2013-03-08T03:17:26.850
I copied a 4gb file and pasted it and it peaked really high at the beginning for about 3seconds, like around 300mb per sec and then dropped to around 50mb/sec for the rest of the transfer. I suspect that peak was due to the ramdisk I have setup, not the harddrive. – cody – 2013-03-08T03:21:48.363
2If you are trying to do multiple task at once, there will be an extra delay every time the computer switches between tasks. Allowing 4 individual copy operations to complete separately and then starting the next one will generally finish much sooner than trying to do all four at once. – washbow – 2013-03-08T03:36:44.157
2Your benchmarks look fine. Don't do more than 1 thing with a hard drive, or it will be significantly slower. Copying 2 files at once will probably take 3-4 times as long as copying them one after the other... A hard drive can only access one part of it a time, after all. – Breakthrough – 2013-03-08T04:20:59.143
