RAID 0 I/O performance wasn’t affected whether the ICH10R or the RAIDCore RC5252-8 controller was used.
If "VST stands for Virtual Storage Layer" then why isn't the acronym VSL and why does the picture of the box immediately above the quoted passage clearly say "Virtual Storage Technology?"/Flash
"powerful storage solution that smokes many professional SATA controllers" I didn't see any in the review to back up your conclusion. I did notice this "standalone controller cards don’t suffer from performance limitations " though. I would also like to have seen CPU utilization numbers. Maybe I'm just looking for an updated Raid shootout. Say 4 port controllers for small business (or power users.)ICH10R, areca, promise, koutech, syba, highpoint, adaptec, 3ware, LSI, rosewill... yeah even the slow/software ones. Show us the difference between a 50$ hardware/software card... 80$ software, 150$ to 300$ hardware, onboard, non-raid, PCI, PCI-E 4x etc. With CPU utilization, glitches, gotchas and price/performance. 0/1/5/10 synthetic and some real load/render etc time. It feels like it's been years since tom's has done a comprehensive Raid shootout.:>
I agree with bounty; I would love to see a new RAID shootout with some in-depth look at the newer-style RAID controllers, and RAID levels. Compare them to software solutions like this, inexpensive solutions, and ridiculously expensive solutions.
i would have really like to see how it performs vs. a windows server software raid 5 setup...they are a little harder to set up, but it supports drive roaming, raid 0,1,5, and 50, and can be put into any windows system after being set up. personally, i dont know why you would get this if you allready have server...
$49usd really is not that much for 'software RAID', but to be honest I know very little about this product: even after reading this article. I suppose if implementation was simple, straight forward, and offered good manageability then it *could* be worth the cost. That said, like Dragon_Nin3 said above - Windows software RAID works very well in a lot of situation, not to mention the other implementations such as Linux mdraid, and Solaris RAIDz. The later here being very intuitive, and very well thought out from an administrators standpoint.
Does it support hot swapping?
Who decided that making the I/O graphs *tiny* was a good idea. I can barely read them. I tried opening the image in a new window which didnt help, so I copied them into irfanview and blew them up a bit but they were still pretty fuzzy. Overall (as mentioned before) not terribly convincing if they expect it to compete with a hardware setup with a dedicated XOR processor... at least from what I could make out on the I/O graphs.-mcg
Why would I pay $49 plus the $150-$290 for their crippled SATA/SAS controllers when I can buy a dirt cheap 4 port SATA controller card and use Linux RAID tools to do almost exactly the same thing. My fileserver currently has a 2-drive RAID0 array, 2x 4-drive RAID5 arrays, and a 6 drive RAID6 array, and migrating/maintaining it is really pretty easy.
I've been thinking of getting one of those 9U server cases that hold 50 hot swap drives, two 24-port areca cards and a decent xeon board for a media server. Yes, it's expensive, but it would give me virtually unlimited capacity for years of HD storage.Another option that I like which works great with laptops is to get a 7-port usb hub, 7 external hard drives and connect it all using a single cord. It's a dirt cheap way to add 7TB to your device, if you can deal with all the ac adapters.
I recently upgraded my desktop box by adding two more 500G SATA drives to the one 500G drive already there, taking out a 250G drive in the process. With Linux's software RAID, I was able to configure a /boot partition as RAID1 with two spares, / & /home as RAID5, and 3 swap partitions without RAID. And I was able to do this with the live data - no need to back up, reformat and restore. Once set up, I got a noticeable performance boost in addition to having the peace of mind RAID5 brings.It's nice that someone is finally bringing software RAID to Windows, but I can't see anyone actually wanting to purchase this for Linux when there already is a robust and efficient free implementation.
bounty is right. It's probably better to check out other sites like Anand's that understand the tech better and aim their articles at a more technical audience.
This was an advertisement infomercial style. They give you just enough info to make it look like it can compete with more expensive solutions and to make it sound interesting in hopes you'll ask more about it. Who wrote this article, Cipro?

Too bad the OCE and OLRM looked interesting. I would have tested it if not for the EULA.
I have tested their software to build a RAID-5 array (3 x 640GB WD SATA), and I am very impressed with its features. I can't comment on reliability, since I've only used it for a few days.However, before buying, I decided to check out the company. I found this news article regarding their recent bankruptcy filing and a bid to purchase their intellectual property (specifically rights to their VST Pro software). Given the buyout interest, it appears that their software will live on even if the company ends. However, I wonder how the next company would handle the customers they inherit with the software. (I think I should buy the software now, since $49 is a great price for everything the software can do, and the new owner might increase the price. On the other hand, it's possible that the new owner would stop supporting it without buying a steep upgrade... many unknowns.)-- Brian

Here is a response from an email on the subject to Ciprico's support address.-- Brian___________________________Subject: RE: VST Pro 2008 licenseDate: Tue, 2 Sep 2008 12:48:43 -0500From: tomh@To: stewartwbHello Brian,Thank you for your interest in VST 2008. As for the current status of VST/RAIDCore software RAID, there is an interested party that has come forward and has presented an offer to acquire the VST/RAIDCore software line and carry forward any licensing agreements and continue to invest and enhance the product. The deal should be finalized very soon. Regards,Ciprico Support
Looks like Dot Hill have acquired the RaidCore IP, has anyone tried getting support for this product lately and received a response?http://investors.dothill.com/relea [...] eID=336233
I've been struggling to find information on where to purchase this software. We had the demo running at our office and it expired right when this deal was going through. I was able to get in contact with Dot Hill and they aren't even sure right now. I should find out later today if I can actually purchase a license...fantastic
