Solved SSD caching question.. Can I use it like this?

December 22, 2012 at 01:45:36
Specs: Win 7 32, 4

I am buying new PC in a week, I will be using it only for Photoshop. ( And of course play games, but its of the least priority). I am planning to buy a 120gb SSD with it.


Question is can I split it into two (60-60, or 70-50 etc) and give one partition for OS and Photoshop, and use the other partition for caching my large hard disks containing lots of photos and .psd files.

I told you gaming is my least priority. And will be buying ivy-bridge with H77 chip-set.

Photoshop can benefit from a scratch disk which is basically a cache just for Photoshop, but it really cannot be the same physical disk as the OS or the disk Photoshop is running off. I would use the SSD for OS and programs, and later, if you need it, you can add a 60Gb or smaller SSD just for the scratch disk.

An ivy bridge with an H77 should be good. If you are going with one of the K series Ivy Bridge, go with one of the Z77 motherboards to get the most out of its overclockability (not really a word, but it gets to the point).

You have to be a little bit crazy to keep you from going insane.

I think the need for that would depend on the memory. How much memory will the PC have?

Is memory related to using an SSD to cache a hard disk?

The Intel software does allow an SSD to be split in this way, but I'm not sure if you can do it for the OS. The Catch 22 is that splitting the drive destroys any existing partitions. I guess you could install the OS to another drive, split the SSD and then move the partition.

But is it worth it? I would either use a 64GB SSD to cache the system drive or else use all of the SSD for the system drive. I'm not sure that caching large data files like photos and videos is particularly useful.

Caching of any kind is most useful with frequently accessed files. In a modern operating system that usually means the OS and applications. Caching of data files will provide less benefit and if you have sufficient RAM the normal system caching should be quite sufficient.

#1 - I will be having about a total 3TB of hard drives all together.

#3 - And I will be going for 16gb 1600ddr3 ram.

The frequently used apps will be photoshop, acdsee and a media player probably.

I dont have a large video library, I need photos to be cached. and I will be accessing some areas frequently, through photoshop.

#2 - If I can use a 40gb partition from SSD as cache. i will go for moving partition with OS to the other half of SSD. and Will it create any technical issues..or is there any choice to install it directly to the half of SSD and use the other half as cache?

With 16GB of RAM, I don't think that you have to do anything else.

So I just use the 120gb SSD for OS and apps... In that case should I go for an H77 chipset, i can get an even cheaper motherboard..?

Right, just use the SSD for the OS & apps. I don't know enough to answer the mobo question.

Thanks a lot Fingers and guapo

I have decided.

#7- I wont be using SSD caching as I will buy 16gb ram.

#8- I will split 120 ssd into two, 70gb for OS and photoshop (I dont need a lot of space in C:\ drive), and the rest as scratch disk for photoshop. Later will think of expanding as you said.

Not going for a k series so no Z77.

Thanks a lot for the links..

Thanks guys for all your replies.. I am loving this site as I am getting more than I ever thought of.. Hats off to all.

"I will split 120 ssd into two, 70gb for OS and photoshop"

You were planning on doing that right from the start & even though it was just recommended that you NOT do that, you're going to do it anyway?

I was planning to use the other part as a ssd cache for my entire harddisks, which will lead me to installing OS on another hardisk, then create cache partition and then move the installed OS partition to my ssds non cache partition, which require me to use atleast and H77 chipset motherboard.

But now thats not the case.

I will just split that 120 into two parts and install OS on one part.


I will leave the other part empty for using it as primary scratch drive for photoshop.

since I understood that using primary drive as scratch disk is not recommended..

Am I still missing something?

I am not using ssd for cache because #5

You can still use part of the 120GB as a logical drive for storage. I just wouldn't use it for swap.

You can use the same physical drive for a scratch disk (separate partition), however, it is less than optimal since it uses the same disk interface as the other partition so reading and or writing on one will have to wait until the other is finished (though faster than a mechanical drive, it still takes time). Using a separate distinct drive is much better and much faster. This was covered above and is covered on the links i provided above.
Your choice, of course.

Alright I will use 120 full for OS and apps.

Later think of expanding with a 60gb SSd for scratch disk..

Thank you all..

Sorry for being an idiot.
