Choppy playback and loading edit from NAS


hi all,

 

having spent last few hours browsing numerous forums , posts info, there nothing find cover specifically, hence new post.

 

we small set (2-3 person team) , have upgraded nas storage system in hopes of eradicating need external hd's while keeping in 1 place. has been issue whilst on externals choppiness 1 of our pc's whilst playing edits in premiere (specs of system below), figuring issue hd's (perhaps rpm speed) hoping solved nas. found quite opposite pc's exerting memory whilst trying load projects nas , once loaded having choppy playback , overall slowness.

 

specs of setup - nas: synology diskstation ds1815+ gigabit connection(cat5e) through router pc

hdd's in nas are: seagate nas 4tb (st4000vn000) x 8 (these have lower rpm of 5,900)

 

pc's running windows 10, date adobe software, 32gb ram , gtx980.

 

footage editing has been shot on fs700 @ 1080p.

 

having tried suggestions other posts changing media cached, locally nas, having no effect , double checking connection speeds etc. thing can think of hdd's not pushing enough speed, resulting in chuggy playback(makes editing impossible). suggestions on how around or improve speed appreciated, otherwise been $3,000 drive.

 

many thanks!

hmm...

 

for multiple video editing workstations, want san (not nas).  might okay if 1 workstation accessing nas @ time, it's not right type of storage intended use.

 

as far bandwidth goes, if you're recording flash memory unit, memory stick, or sd/sdhc/sdxc memory card in camera, you're not exceeding 28 mbps.  drives in nas should able sustain plenty of overhead regardless of rpm , while in jbod configuration (so, without being in raid 0). if you're shooting 12-bit 2k , 4k raw available via hxr-ifr5 interface unit , axs-r5 recorder, may need cut proxies lower bandwidth , online via raid 0 storage attached directly or san.

 

storage issues aside, have had chance play 960 fps super slow motion?
