  • Sometimes in life you just do something that may not make sense just to try it and end up glad you did.  This is exactly what happened when I grabbed 2 Vertex 120G SSD drives which are fast in there own right, and hooked them together to create a 240G stripe.  I had always wanted to try to RAID 2 SSDs together just for the fun of it but it always seemed nuts to me.  After all, how fast is fast?  The fact that I even asked this question was enough to finally cave in to the temptation.  Anyway, as it turns out I had picked up an extra Vertex 2 during a sale which was just sitting here waiting for something to do so when I saw them on sale again I decided to give a shot.  I figured if it did not work out I could return the second one or repurpose it to a laptop later, but curiosity got the better of me and I just needed to try it.

    The build

     

    I used the OCZ Vertex 2 120G version to match up with the RAID enabled controller that is built in to the Asus Sabertooth.  The first challenge was how I was going to mount two of these SSD’s into my Lian-Li case.  Mounting two SSD drives is not normally an issue except that this case uses a drive cage with 4 drive caddy’s which accommodate either one 3.5 or a 2.5 inch drive and since I already have 3 drives in there, putting 2 more drives in would require some sort of adapter.  The other issue is that adapters are typically designed for a screw in application and installing this in an existing adapter would also be a bit of a challenge.  To solve the problem I selected the Thermaltake 2 x 2.5 inch adapter and installed the SSD drives in this adapter.

    After installing the 2 drives in the adaptor, I mounted the adaptor onto the Lian-Li drive tray which then allowed me to have the 2 drives on one tray using a basic tywrap which held everything in place very securely..

    Setup

     

    Things are not always as easy as they should and this is not exception.  What should have been a brain dead task turn out to bit a bit more complicated.  After installing the drives and attaching the power and sata cables, I went to the BIOS and enabled the RAID, once I rebooted, I was greeted with the RAID configuration screen and quickly created the stripe hit save and to my surprise I could not get the system to boot.  Turns out this is a common problem if you enable RAID after you windows installation (lessons learned). Fortunately, once I created the stripe, reset the controller to AHCI, I was able to boot into windows, load the Intel Raid Storage driver and the stripe showed up in the disk management as a single volume set and ready to go.  Once I got that far, it was downhill from there and all went very smooth.  Once the stripe was completed, I did a quick restore to put all my data and programs back and in less than 15 minutes, I had a 240 gig drive program drive ready to go.

     

     

     

    Final Configuration

     

    OS Drive – Vertex 2 120 Gig

     

    Data Drive – 2 x Vertex 2 120 Gig in a RAID 0

     

    Misc Drive – 1 x 1 T Caviar Black (

     

    Local Backup Drive – 1 x 1 2 T Caviar green used for Acronis Backup

     

     

     

    Performance

     

    I think it goes without saying that SSD’s are fast but let me tell you that when put two of them in a stripe, the speed is breath taking.  I included some single SSD benchmarks for comparison and keep in mind that benchmarks on the new sandy bridge systems are a bit under stated.  As you can see the benchmark performance is outstanding and more importantly it translates to user experience as well.  Everything written and read from the new volume was noticeably faster as was the games I ran.  Game start time was quicker, playback was smoother, and writing especially large files was significantly faster.

    Trim Support

     

    One of the deterrents in the past was that Trim was not enabled in a RAID configurations.  Intel now has enabled trim on their latest storage driver so we can benefit from not only the speed of the stripe but not loose Trim support in the process.

    Conclusion

     

    So if you ask me was it worth it, I would have to say, absolutely!  If you ask me would I do it again, the answer would be, probably.  It is always nice to have the simplicity of single drive, and not have to worry about drivers, or controller configurations, but the reality is that no single drive can match the performance of two of same drives striped together.  The speed of this 240Gig drive is faster than the standalone 240G Vertex 2 for almost the exact cost.  The argument use to be that you would loose trim but now that is no longer an issue.  If you can put up with a few extra steps and few more variables, you will definitely love the outcome, cause I sure do…

     

    ***Update 3/26/11d*** It appears that there may be an error in Intel's help file and the Trim support for a RAID O does not function.  More research is required.

    ***Update*** It appears the information in the Intel hlp file was incorrect and Trim may not support RAID 0. More research is required. Will post update.

    I wish ATTO had kept the same scale for both tests so it would be much more obvious that the stiped setup was 2x as fast. But, a very interesting test in any case. Thx for posting (and spending the money to do the test) :)

    • I throw this out every once in a while.  Is anyone interested in writing up "semi-formal" reviews here on the forums?  I say semi-formal because they don't have to be pro level, just a good attempt at telling the story about the gear.  Something you have purchased lately.  You don't have to go buy stuff, just incorporate what you have already have purchased.  Hit me up with any questions.  You never know where it will lead!

    • D-Link has dropped a couple of new products and additions to their lineup of smart home gear.  Hold on because there is a lot of gear!
      Let's start with cameras.  D-Link has new Wi-Fi cameras, the Full HD Pan and Tilt Pro Wi-Fi Camera (DCS-8302LH) and Full HD Indoor and Outdoor Pro Wi-Fi Camera (DCS-8526LH).  These are not just new, and good looking cams, they can now perform people detection and glass break detection.  The new cameras also feature expanded ways for customers to save video, including ONVIF Profile S, which enables custom storage and streaming options to personal NAS devices, built-in storage microSD capacity up to 256 GB, as well as free and paid cloud storage options. 
       

       
      This year's camera models include both an indoor and an outdoor model. The outdoor model features a spotlight and siren that can be triggered when motion is detected, deterring potential intruders. The indoor model pans around to give a full 360-degree view of any room and tracks motion. Both include two-way audio. 
      Full HD Pan and Tilt Pro Wi-Fi Camera is the model (DCS-8302LH), available in Q2, 2020, and retail pricing will be $99.99.
      Full HD Indoor and Outdoor Pro Wi-Fi Camera is the model (DCS-8526LH), available in Q3, 2020, and retail pricing will be $119.99.

      Below is a part of the order that I put in!  
       
       

       
      The Heather Grey above is the Extra Soft version and it is awesome.  I highly recommend the softness!    The "Chili Red" is the Tri-Blend and probably my favorite feel and color.

       
      This is the Zip-Up Hoody, Heather Indigo, Sponge Fleece, Men's, Large.  In my podcast I couldn't remember what style it was but it is Sponge Fleece. It's REALLY soft on the inside. Soft outside as well. The only problem is with the zip up hoody the logo is on the back. Regular hoody, it will be on the front.

    • OneDrive Personal Vault and expandable storage
      Microsoft's OneDrive has a few new features and options worth pointing out.  Personal Vault and Expandable Storage.
       
      Personal Vault is a protected area in OneDrive that can only be accessed with a strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. 
       
      Personal Vault gives you an added layer of protection for your most important files, photos, and videos—for example, copies of documents such as your passport, driver’s license, or insurance information—should someone gain access to your account or device.
      Plus, this added security won’t slow you down. You can quickly access your important documents, photos, and files with confidence wherever you are, on your PC, OneDrive.com, or your mobile device.

       
      Beyond a second layer of identity verification, Personal Vault also includes the following security measures:
       
      Scan and shoot—Using the OneDrive app, you can scan documents or shoot photos directly into your Personal Vault, keeping them off less secure areas of your device, like your camera roll.
      Automatic locking—No need to worry about whether you left your Personal Vault or your files open—both will close and lock automatically after a period of inactivity.
      BitLocker encryption—On Windows 10 PCs, OneDrive automatically syncs your Personal Vault files to a BitLocker-encrypted area of your local hard drive.
      Restricted sharing—To prevent accidental sharing, files in Personal Vault and shared items moved into Personal Vault cannot be shared.
       
      Taken together, these security measures help ensure that Personal Vault files are not stored unprotected on your PC, and your files have additional protection, even if your Windows 10 PC or mobile device is lost, stolen, or someone gains access to it or to your account.
       
      Expandable Storage
       
      If you are and Office 365 Subscriber you get 1 TB of OneDrive storage space with all the other Office goodies like Word, Excel, etc.  I know personally that I have gone over the 1TB limit and have always wanted to be able to add additional storage to my account.  Now you can!

       
      Pick and option and keep on hoarding, errr, I mean saving! Cancel anytime, upgrade at any moment.

    • Ubiquiti adds new items to the Unifi Line including UAP Flex HD and the Unifi Dream machine
      Ubiquiti has been busy.  There area ton of new items to recently released and I'm going to share two of my favorites.
       
      The UAP Flex HD and the Unifi Dream machine. The Flex HD is a mouthful of descriptors like most of UI gear is.  It's a 2Ghz 2x2 MIMO, 5GHz 4x4 MU-MIMO, POE, Indoor/Outdoor, multi mount, mesh point that is no bigger than a can of Coke.

       
      You will still need the Unifi controller although you can configure it with basic functionality with the Unifi App.  I've always found it's best to configure with your controller and then use the app as an add-on.  There are several mounting options that include sitting it on a shelf! That is something that Unifi has not had before unless you count the ceiling AP I have awkwardly mounted placed on top of a few books.  It can be found on the Unifi store for $179.
       
      https://store.ui.com/collections/wireless/products/unifi-flexhd
       
      The Dream Machine is an altogether different beast that I hope lives up to its naming.  This is the gateway drug, for lack of a better term, to the Unifi world.  The starter kit.  It is an Access Point, Gigabit Switch, Security Gateway, and the Cloud Key all in one package.  The latter being the most significant as this is something that has deterred new users from getting started with Unifi.  Requiring new users to purchase a $100 item just to run the AP's has been somewhat of a roadblock in the past.  Granted, that is improving every year with the ability to run it in the cloud, on a NAS, a Pi, Docker, MacOS, and of course Windows, it is still a barricade to getting up and running when manufacturers such as Eero offer simplicity in an app.
       

       
      The switch includes 4 LAN Ports and 1 WAN port.  All of which are Gigabit and security services such as IPS are rated at Gigabit speed. It's $299 in the Unifi store but I'm unsure how nicely it will play with other Unifi gear.  This may be a nice "first AP" with its built in Cloud Key if you can add additional units or other Unifi access points.
