A question for PCS about mSATA Cache/Storage Drives...

I thought I was pretty clued up about the best options for a Vortex III 17.3... until I saw an online review from Xoticpc for the US version, which opened me up to the world of SSD cache drives. Up until now, I thought a SATA3 SSD was good enough!

My question is this. The reviewer specifically mentions that he has the 80GB Intel 310 mSATA working in a RAID conjunction with an Intel 520 series SSD, and goes on at length about the performance improvement.

However, when I phoned in and spoke to one of your advisors (who was very patient and helpful), he was adamant that the 80GB Multi Level Cell 310 mSATA was a bit extraneous, and that what I really wanted was the 20GB Single Level Cell 313 mSATA to work in conjunction with my SSD: pointing out that of the three options available, that was the only one listed as "Cache Drive".

While I have no doubt you guys know what you're doing, I also know Xoticpc are supposed to be pretty clued up, and I just don't really get the difference between the two options?? Does the 313 not need to be set up in RAID... is that it? But in which case, would setting up a 310 in RAID not do the same any way, but with the advantage of more space?

The reason it's important, is when I went back to alter my options, I noted the 313 mSATA Cache is actually quite a pricey addition at £72 for only 20GB... whereas even the 40GB 310 Multi Cell is slightly less at £68? Bottom line; do you think it's a worthy upgrade any way??

My brain hurts. Please can someone explain it in layman's terms (relatively any way)

Cheers

Basically if you are going to use an ssd drive for a cache dirve you should be looking at an SLC one. SLC Flash is much more durable than MLC. A cache drive performs lots of write operations and MLC would wear out much more quickly than SLC. Obviously SLC drvies are much more expensive, but there is a reason. I think SLC NAND can perform 100,000 write/erase cycles whereas MLC is about 3000. 20GB is fine size wise for a cache dirve.

If your plan is to have a large drive such as a 750gb scorpio black and get ssd perfomance then the 20gb intel 313 series cache drive is ideal.

No, that's the point... I'm going to be running a 520 series SSD as my 1st HD any way.
I see how the performance boost for a 7200rpm HD for £72 is definitely worth it, but is the performance boost from combining mSATA cache with a SSD worth the same?
