SSD cache'ing with two 4gb ssd?

post #1 of 9
Thread Starter 
Hello, I have recently come into possession of two small ssd's, 4gb ea. They are Apacer AP-SAFD25MAA004GS-T http://www.mouser.com/ProductDetail/Apacer/AP-SAFD25MAA004GS-T/?qs=%2Fha2pyFaduhPPRRWuGIR06YPhzi7dD1Obv7Y7pJWFMHks2u16eux%252bX3seqr%252bZOq9

I was wondering if it was possible to set these up for cacheing my hdd's? I have a 128gb samsung 830 as my main os/frequently used file drive, but would like to use these little guys to cache for my 1tb hdd? Can it be done, or what can I do with them?

I am running an asus maximus v gene z77 with i5 2500k, 128gb samsung 830 for main os drive, and the 1tb drive for steam/music.

There are adapters/raid cards that allow for SSD caching if you don't have an intel Z series motherboard.

If you use the 1tb mainly for storage you won't see any real gains from having it cached tbh.

You can probably use one of them for SSD caching if you have a Intel Z68 or newer chipset with Intel RST. You'd need to enable RAID mode in the BIOS, and that might require you to adjust your Windows configuration a bit before it will boot.

I doubt you can use both of the SSD for caching, as Intel RST (and the Marvell equivalent used by ASUS and other board manufacturers) will only utilize one SSD per HDD for cache. If you had TWO 1TB hard drives, you could dedicate one SSD cache drive for each HDD... I think.

Those little 4GB SSD might be better sold on eBay. They're typically used for industrial diskless workstations or embedded applications like point of sale, etc.

I think the minimum cache size for Intel SRT/RST is 16gb. Like Arkuatic said there are adapter or raid cards you can buy, but honestly I think you would just be better off buying a larger SSD. Not sure it's worth your effort to make it work with those 4gb drives.

those ssd drives are almost identical to the read/write speeds of a normal hard drive.
i doubt you'll even see any performance by using them.

The sequentials are a bit inferior to most modern traditional hard drives however I would assume their randoms are still better; randoms would be a bigger factor for cache.

Will update the OP
I am running an asus maximus v gene z77 with i5 2500k, 128gb samsung 830 for main os drive, and the 1tb drive for steam/music. From the responses I can't really do much with these it looks like, as I read here and other places that Intel SRT needs min 16gb to function.
If I can't cache with them, what should I use them for?

a 2gb sells for $24 on ebay, they dont show a 4gb on there.
so maybe you could get $40 per out of them on there and then take that $80 and buy a larger ssd drive to do your caching on.
thats provided they sell, not sure on what the demand for those would be.

If I can't cache with them, what should I use them for?

The minimum capacity required for an Intel SRT system is 18.6GB, where that figure comes from, I don't know.

What to use those SSDs for? Use one as your download drive and browser cache. Just move downloads off of it and clear or limit your brower cache size. Put your pagefile on it, if you use a pagefile.
