One big samsung vs 2x small samsungs in raid 0

post #1 of 19
Thread Starter 
So i have 2 questions. First one. I was looking at some reviews. And if i'm right. A samsung 840 pro 256GB in RAPID mode is two times faster then my current kingston hyperX. It also has lower access time. Soould i feel the difference in real life usage? Second question. If i want 500GB of SSD storage is it a better idea to buy 2x 256GB samsung 840 pro's and run them in raid 0 or should i buy a single 500GB ssd and run it in rapid mode. Since samsungs do not support RAPID in raid 0. Witch option is better and why? Witch option is faster?

Pc that will be running this in short terms. i5 4570, gigabyte z87m-d3h, 2x8GB kingston HyperX ram.

EDIT: Also i'm will be using that ssd 24/7, my kington HyperX has got 17500 working hours and 10TB of write. So considering that is it worth buying a samsung PRO or an EVO ?

I can actually answer this from personal experience, I was unable to tell the difference. Now to be fair it was an 840 EVO vs. my HyperX but in real world use the drives felt the same.

As for RAID vs one big, I have found I prefer option three, I run dual 240 gig and just have data go to a drive as needed.

Yes but have you compared yours samsung in RAPID mode with the kingston? I mean, i'm not buying this ssd because of performanse, i need more ssd storage, but i' curious will i feel the difference. An 840 EVO with no RAPID mode turned on is not much faster then the HyperX. However when you run it in rapid mode the difference is huge... at least in benchmarks

You know, that RAPID stuff is just software. There's other software like this around where you can create a large extra cache, though I have not seen anything free. Samsung bought one of the businesses that built software like this and that's where RAPID comes from. It's the rebranded version of what that business sold originally.

I don't remember names of the programs so don't really know what to search for with Google.

Well yes that's true but still they are hitting amazing speeds. Also my kongston has acces time of about 0.3xx miliseconds. Whereas the samung runs at 0.016, that is a lot lower. And yes, if i run two in raid 0 i get almost two times higher speeds. You should be able to feel the diffeerence between an ssd and two ssd's in raid 0. But then there is almost no difference between two samings in raid 0 and one samsing running in RAPID mode. i'm confused.

I meant to say, you might want to try to hunt down a comparable software and use it with your Kingston.

My 840 pro's 256Gb Raid 0. Feels exactly the same as my old Crucial M4 120GB.

Be careful with Rapid mode. It ups benchmarks but when I tested loading times on Skyrim, I found no change. Yes, there are imperfections to my measuring methods because I can't be infinitely precise, but I OCD'ed and spent at least half an hour if not an hour benchmarking loading times under certain conditions. I saw only benchmark increases in performance and no real world gains. Plus, it hogged up my ram.

Yes i was afraid of that. But then raid 0 should properly incease speeds of those drives? So it turns out raid is a much faster option in real life?

I looked around for the names of programs that are similar to Samsung's RAPID. I found "FancyCache" and "SuperCache".

http://www.superspeed.com/desktop/supercache.php
http://www.romexsoftware.com/en-us/fancy-cache/

This was an interesting thread, discussing programs like this (I'm linking directly to the page with the most interesting post):

http://www.xtremesystems.org/forums/showthread.php?267879-FancyCache-software-RAM-based-disk-cache/page3

The second post on that page, that "Vapor" guy used PCMark to test it, which is trying to simulate actual programs like MS Office for its tests, not trying to find out raw numbers for throughput etc. like synthetic benchmarks. The extra cache software did basically nothing. What Windows does by itself is already as good as it gets. This was done a few years ago, so software like this might have improved, but the same could have happened to Windows, the current 8 might also be improved compared to the 7 from that time.

So it's probably exactly like Darkwizzie said... that kind of extra cache software is a cheat for benchmarks but not doing anything for normal programs. It might actually be a bad idea to use it because you will lose data that is inside the cache if there's a crash of that software or the whole PC.

Another option for you might be to look around what happened to things like that Plextor announcement about SSDs for PCI-E. There was also similar news about an Intel product, and there's already Samsung PCI-E stuff used by Apple. Those kind of SSDs will do what you want with regards to extra speed without RAID because their PCI-E connection has no limit like SATA. They might be very interesting if they're available soon.
