Free Space In Drive Affects Performance ?

[nitrococuk]

Hi. 1-2 months ago, I had too many free spaces on my D harddisc drive (nearly 70 gb free). But during couple of days, it decreased to 35 gbs due to some recorded private tapes.

It is really getting hard to get a nice real-time playback performance on my Edius projects right now. there are currently more frame drops than there were ever.

can it be because of decreased free space on HDD ? I can not find any other reason for that.

Hard drive speed can definitely be a problem

it decreased to 35 gbs

hmmmm ?? 35 gbs ==> what is this ??

35 GByte / sec ??
35 Gbit /sec??
35GB free space on the disk??
35GB free space from total 250 \ 500 \ 1.000 GB??

NLE - media disk needs 15% - 20% free space (on a defragged disk)

who many drive have the PC ?? (for OS + programms \ pagefile.sys \ media)

Minimum 2 disk (a -b are different physikalic drive)
a) OS + programms (pagefile.sys)
b) media

Optimum: (a - f ==> are different physikalic drive)
a) OS + programms
b) pagefile.sys (on seperate parition, with fix setting) + space for save files
c) projectfolder with "rendered files"
d- f) media

I am sure he meant 35G free on the HD drive

[antonsvideo]

well, if the hard disk is a 64GB SCSI, then 35GB free space means the drive has 50% free space and it will work fine

if the drive is 1TB, then the drive has only a few % left and will cause problem

basically, a drive should not be over 80% full

Just a question regarding your drive D, is this a partition on your boot drive C, or do you have at least 2 physical HDD's in your system ?

35 GB is a whole Lotta empty space if you ask me (2.5 hours DV / 1 hour HQs), though it could give hick-ups if it was badly fragmented (or a partition on the boot drive)

Anton made a good rule of thumb statement, try not to exceed 80% full (and defrag)

[STORMDAVE]

Don't see a reason to defrag nowadays (Unless it's a system drive). If you can do a quick format, you're better off.

...unless you are mid project, then this could cause a problem.

35GB free space shouldn't cause playback issues, especially on modern SATA drives. Some of your recorded files are probably sitting on a bad sector/patch of the hard drive.
I would copy all files to another hard drive (or after finishing the project) and do a full format with a scan for bad sectors.

35GB free space on the disk i meant....


mmmm... i dunno... there happening so many frame-drops during playback...

But i forgot to tell you that frame-drops seen when Edius try to play "uncompressed RGB video clip" or "video clips contained many effects and keyer" in timeline....

That part we understand :)

Uncompressed can not play on many of our systems, you need something pretty fast for that.
To have realtime power with many clips that have effects etc you need also a powerful CPU & GPU.
You could try SHIFT+G before you play, and when you want to play use SHIFT+SPACEBAR.

To comeback to the earlier question:
Is your drive D on your boot drive, or on a physical 2nd HDD ?

[nitrococuk]

Shift +G and Shift+Spacebar... what are they for ?

My Drive D is on my boot drive...

[GrassValley_KH]

To clarify on uncompressed playback performance, you need solid, sustained disk throughput to match the size of the data being played back to avoid dropped frames - so it's not so much the speed of the CPU or amount of ram, but how your hard disk drives are configured (and their speed).

Typically, uncompressed editing requires very fast RAID configurations. Since this is a costly exercise to set up, we continue to recommend the use of the Canopus HQ codec instead.

[pjsssss]

Also it is HIGHLY recommended to have your edit drive on something besides your boot drive.

My Drive D is on my boot drive...

If you would have answer a bit earlier, then we would have known it from the start (my hunch was right).

If you want better performance, add 1 more HDD for your video data, it is not good to put that on your boot drive, that's why you have poor performance.
