Viewer Installation. Install on SSD or HDD?

Question

  • 0

I have the viewer installed on an older slower hard drive and the texture cache installed on a newer quicker hard drive. It does help. If you tp often, this configuration works well and does improve performance. I do not have a SSD drive but did for a time use this.

http://memory.dataram.com/products-and-services/software/ramdisk

This allows the cache to run from the RAM within a PC instead of the hard drive.

It does have risks, by-the-way and should perhaps only be used by "advanced users".

I was very pleases to see that the cache size was increased in the last viewer version. This should help. (See preferences). Now it will be a long time between cache refreshing I hope but it is still to early to tell (texture corruption????)..

I have the viewer on my 64GB SSD and my cache on a 7200 RPM HDD.  Works very well.  With all that RAM, you might want to set up a RAM Disc for speed, and then set it to write the contents to your HDD when you shut down.  That would give you the fastest possible cache (but would add a short delay to start-up and shut-down to load and then copy the RAM Disc).

I have just reinstalled my Desktop PC with Windows 10 and Firestorm etc on an SSD. I also have other 1TB and 2TB Disks in the system but for now, these are both totally empty. Sadly from having a previously very slow, but reliable system, I now have a system that crashes every time it detects that it is a laggy space!

Does anyone know if there is a known problem with Firestorm and SSD? The Windows 10 element works absolutely fine!

No issues for me on SSD.  Cache also on SSD. I do NOT clear cache unless there are texture issues or "invisible mesh" problems.

I'm of the school that prefers re-using old questions, Lillith.  Having a forum with ten thousand versions of "Help!  I'm a cloud!" just seems...untidy.

On the other hand, ANSWERING questions that are several years old...well, that's just silly.

re using i totally agree.. and use search.. 90% of the most common issues are answered hundreds/thousend times.

if new solutions come up it even can be usefull to place it under older questions....but again... if search is used.

In the top menu bar of the viewer, go to Help -> About Firestorm, click the "Copy to clipboard" button & paste all your system information here.

I have all my software programs installed on my SSD, including both 32 bit and 64 bit Firestorm.  No issues.  I use my spinning hard drives for data, including Second Life caches.  Be sure your video drivers are up to date.  I had a recent Windows update that resulted in all sorts of problems, both with SL viewers and other programs, until I updated my drivers.

If your spend most of your time exploring and shopping you want your cache on the fastest drive. For me that is a RAMDrive. RAM drives are the fastest. Several times faster than an M.2 PCIe connected SSD, which is a few times faster than a HDD.

If you play the inventory and fashion game part of SL and are constantly opening panels and moving inventory, you want the viewer installed on a fast drive too. The UI will be a bit faster.

From limited testing I know having the cache and programs for SL on the same drive does slow things down, but not much. The SSD and RAMDisk are fast enough you can put both on them and still see a significant overall gain. But, I can't see that much improvement in UI performance. So, I have my viewer programs on a slower drive. I do see a difference in performance and scene render time with a cache on the RAMdrive. For the absolute max you want the programs on one drive and the cache on another and each using a separate IO channel.

All of this goes sideways if your PCIe bus gets bottle necked. The newer z170, z270, and z370 motherboards are adding more and more PCIe channels. New boards are less likely to bottleneck. 

There are disk drive... or now storage device... benchmark tools. You can see the speed difference between your storage devices.

The problem there is that almost nobody has enough RAM to make a proper ramdisk out of. Most people are still on 8gb, 16gb is getting more common but its still mainly for people who game a lot.

Even 16gb of ram really isnt enough for a proper ramdisk, especially if you need that 16gb of ram as well. Ive got the xeon system now wtih 32gb of ram so that might be an option but really it gets into the land of diminishing returns, im giving up half my ram for a place for my browser to cram stuff and an SSD would do it just as well, with a near negligible speed loss.

As for this thread from 2011, if anyone cares, stick the viewer cache on the SSD, it doesnt matter where you install the game, the boot time for the game i pretty quick anyway.

my friend has got ssd what he does is he installs to hdd, thus freeing up the ssd to use window programs, so it copes better the the short cut is on the desk top, but games are on hdd

bearing in mind he has a really powerful i7 based pc, i suppose the way forward would be some large ssd disks , but they are really fast drives, one prob was when they first came on the market, he had a spike in the power, shut down his pc, and killed the ssd could not get it to work again but they may have improved on them now

i tried ramdisk was not very good to be honest

i have been having a few issues with firestorm since the update made me wonder if it need a patch or update may be that it gets very buggy, found it uses a lot of memory as well ,

And that, ladies and gentlemen, is why you don't go cheapskirt on your power supply, the main component that keeps all your other hardware alive and healthy

Right, but that's "all your other hardware" and (as far as the story goes) the machine's mainboard components and other peripheral controller circuits were apparently spared, whilst the SSD fried. Still seems the SSD design might have been more robust.

Really I'm just saying that SSDs have gotten a lot more reliable than when they started to get popular. On my personal machine, for five years I've used a (then fairly high-end) SSD for everything except long term storage of big slow data files (pictures, video, audio, source repositories, ...) that go to the cloud, with nightly backup (to local NAS but could be cloud). I've not had a minute of downtime in five years with that setup.

I know, "knock on wood" because SSDs' NVRAM isn't really supposed to be ideal for constant re-writing such as cache (or swap), but I haven't had a problem. YMMV I guess.

And why we use things like surge protectors.

RAMDisks are fast. The faster your memory, the faster the RAMDisk.

The first SSD's had a short life expectancy. The Samsung EVO850 warranty is 10 years with a total expected life cycle of 114 years. The calculated life of it based on writing 2GB/yr is 340+ years. See The life span of an SSD (updated 3/2018).

Life is dependent on write cycles. My SL caches are set to 10GB. I am certain I write way more than 2GB per year to my drives. But, my caches are in a RAMDrive or hard disk. I save the SSD for things where I read the same info often or need the best write speed I can get, i.e., recording video.
