Worth it?

I have spare 60gb SSD laying around. I have larger SSD for system drive do wondering if I should use it to speed up a storage drive.

Anyone done this ?

Thoughts ?

Must admit I've not tried it, but I wouldn't think you'll get much or any benefit caching a storage drive - presumably all files on there are quite large(?) so it won't be able to cache many of them. And I think the main benefits of SSDs come from caching relatively small frequently used files (such as all the OS files, program files, etc) In fact I seem to recall some info about Intel SSD caching not even trying to cache files bigger than a few MBs so you might end up caching very little.


EDIT: Having said that (and reading a bit more about it) if you have programs or games installed on your HDD you should see some decent performance improvements. biggrin.gif

I use SSD caching on my HDD in my development PC. I even got one of Intels special cache SSDs for that purpose (20GB SLC drive)

I don't have room on my main SSD for all the development resources i need (and some games are on there as well), and since its quite a lot of small files, it sure feels like the cache is doing a good job.

Cool. Thanks.

Easy to set up?

Just install drive and use Intels driver tool in Windows, nothing spectacular.

Thanks for posting this. I was thinking of doing the same for my dev machine at work with one of the cache SSDs but I was not sure if it would benefit vs. just replacing the whole HDD with a large SSD (expensive!). I'd give anything to speed up IntelliJ biggrin.gif.

Awesome! I'll give it a go!

It does not compare to a real SSD at all, there is still a world of difference there. But it does help of course.

Mfusick 11-20-2012 09:46 AM

Yeah I have SSD for my Os. I'm thinking just use my spare drive to boost system storage drive.

*Cough*

ZFS could use that smaller SSD as a cach for your storage server.

*Cough*

Pure storage doesn't need caching. You can easily saturate a GBit network line with a good storage setup, everything else is just wasted.

But would I benefit using that on a 20TB whs server vs a 2TB local HDD ?

How big SSD can it take ?

Can you use it to boost a RAID0 array of two 1TB 7200rpm drives ?

I was thinking more on my local HDD (2TB Hitachi 6g 7200rpm)

I use it for all sorts of stuff that's not permanent storage.

Tell me more. You have my attention. Why would I change to this on my server rebuild?

What's advantage over Flexraid and WHS2011 I have now ?

I don't see any benefit for media storage, even if the network weren't the bottleneck, assuming the caching scheme is some kind of variant of LRU. Think about these http://en.wikipedia.org/wiki/Cache_algorithms compared to the pattern of usage with media storage -- it's too random.

I'm not concerned with media storage as much. I consider that permanent storage and place finished movie folders on my server. Once that's done all I need is to play it back. That's easy.

I'm more thinking of a local HDD. I have 4.3Tb of local storage on my desktop. One hitachi 2tb 7200 sata3 HDD, a 2tb RAID 0 array of two Samsung 7200rpm 1TBs, and a 300GB velociraptor than holds my current organized iTunes mp3 collection.

All of my music and movies are stored on me Flexraid server.

My local HDDs are for all sorts of non permanent stuff. I use them constantly -
