Data is the RAID level of choice for operations that require zz tolerance and rapid disk
speeds.In order to install zz RAID 10 You would need to make the decision of using a
hardware or software RAID solution. I chose software because it better performance
and also you can try The hardware z Vantech, it gives four SATA on top of the one
ports and supports PCIe x4. The cost of this controller is $50 on Ebay, or amazon .
A RAID controller is a card or chip located between the operating system and the
storage drives, usually hard disk drives. RAID provides data redundancy and/or
improves hard disk drive performance; most RAID levels do both. RAID does provide
redundancy on SSDs, but does not improve SSD performance. RAID manufactured
specifically for SSDs will provide both redundancy and improve performance.
RAID controllers work by virtualizing the drives into distinct groups with specific data
protection and redundancy characteristics.
RAID controllers are classified by multiple characteristics including drive types such
as SATA or SAS, the number of ports and number of drives it can support, specific
RAID levels, interface architecture, and how much memory exists in native cache. For
example, this means that a controller manufactured for a SATA environment will not
work on a SAS array, and that a RAID 1
RAID controllers are not storage controllers. Storage controllers presents active disks
to the OS, while the RAID controller acts as a RAM cache and provides RAID
functionality. The number and identity of RAID disks depends on a RAID controller’s
configuration.
As I finish up this week discussion I went on google and search for raid controller
but when I was looking on the previous types I didn't like the function nether didn't I
trust the maker so I search and find a better type and the hardware I choose to
purchase is a Systor 1 to 1 SATA 90MB/S HDD SSD Duplicator/Sanitizer - 3.5" &
2.5" Hard Disk Drive / Solid State Drive Dual Port Hot Swap (SYS101HS-DP) This
come fully complete and easy to use and the unit that can clone a 3.5" and 2.5" hard
drive to multiple hard disks alternately in a single touch of a button.
Systor HDD Duplicators are also DoD compliant when it comes to sanitizing / erasing
data in the hard drive, this feature has been added to ensure that there are no trace of
content left behind and for the consumers security and peace of mind. The device got
a 3 years labor and 1 year warranty and the total cost for purchase is $260. I
personally think for me to install this device it would probably take me up to 5 to 6
hours because of breaking down and installing which I got small amount of experience.
So I read up on RAID and decided that I would purchase the RAID 10. But if it
came down to having a budget or being limited on funds I would go with the RAID
5. The RAID 5 being the more economical choice, it will perform well. The only
difference is it does not mirror the information but the other disc can recreate the
information using parity. So I found a reasonably priced one on google shopping for
about $65 and can run up to about $300. The install time is what might take time
since usually the part is functional already and would require minimal configuration
unless you want to customize the configuration. I chose the RAID 5 controller since it
was the most economical and being that I would consider myself a beginner. It
seemed more install friendly to me being that is practically functional as soon as it is
installed. If I was more at an advance level I would definitely have opted for the
RAID 10 controller. RAID stands for Redundant Array of Independent Disks, which is
basically combining the use of multiple disk drives for better performance. RAID is a
bit more complicated than I would have thought, there are a few different raid levels;
0, 1, 5, 6 and 10. The video I chose was Linus Tech explaining the 3 most simple
levels of raid, 0, 1 and 10. What you are trying to accomplish with your memory
system setup is the most important factor in figuring out which level of RAID you
want to implement. Raid 0 is striping, you will be sacrificing reliability for speed.
You will be using 2 or more drives striped together, which can mean you will keep
maximum memory capacity, the drives are striped together for speed meaning if you
loose one drive the others will fail as well. Raid 1 is safety and reliability, while
connected with the other drives you will still only have the capacity and performance
of only 1 of your drives. The great thing about raid 1 is if a drive were to fail, the
data will still be saved on the other drives. Raid 10 rather than be “10” is a
combination of both RAID 1 and 0 hence RAID 10. Raid 10 you will have 2 sets of
striped drives that are also mirrored them against each other. Level 10 does have the
con of having less storage than you're purchasing for the trade-off of data safety.
Since I will be using 4 hard drives, 2 HDDs will write the same data as each other,
but not the same data as the other 2 HDDs, so you will have an effective storage
capacity of 12TB.
My Raid configuration that I have put together will only cost $765, and it would only
take a short amount of time to physically install in the system, and it should only
take 10 minutes to setup raid.
I chose my Raid controller because of its 512MB cache, and it's on board battery to
protect the cache, which is very vital to the Raid setup.
I decided I would buy a RAID controller that supports RAID 10. I chose RAID 10
because it provides better performance and is a combination of RAID 1 and RAID 0.
It provides fault tolerance and disk mirroring. With RAID 10, data is striped across
disks. When one of the disks gets an error or begins to fail, data is automatically
recreated from the distributed data block. A benefit to RAID 10 allows drives to be
hot-swappable with no interruption to users in the case a drive fails, and you need to
replace it. Because data can be rebuilt to new disks as failing disks are replaced, it is
a good solution for fault tolerance. It is the RAID level of choice for operations that
require fault tolerance and high disk speeds.In order to configure RAID 10 I would
need to make the decision of using a hardware or software RAID solution. I chose
hardware because it offers better performance and flexibility. The hardware I chose is
Vantech, it adds 4 extra SATA ports and supports PCIe x4. The cost of this controller
is $59.99 on Ebay. In addition to the controller I would purchase 4 identical hard
drives in order to maintain data integrity and not run into errors when setting up
RAID. Dealing with RAID issues is just like dealing with a single hard drive issue,
except that you have more parts that make up the single storage unit. If your RAID
array isn’t found or stops working, try to narrow down the issue. Is it one disk that’s
failed, or is the whole system down, indicating a problem with a controller or the
software? Along with external enclosures, which require a separate connection to the
computer, most external RAID systems have status indicators and troubleshooting
utilities to help you identify problems. Definitely use those to your advantage. I chose
to go with the LSI 9212 it says it is compatible with all major OS systems and has
the SMART error detection built into it. The raid controller is also the PCIE 2.0 X 4
and will fit the current open slot on the motherboard. The controllers offer RAIDS
from 0, 1, and 10 this gives an option to do many different RAIDS. The controllers
also offer hot spare support so a component can be replaced and not shutdown the
system while doing so. To have the most redundancy of the setup you can run RAID
10 but the downside you would need to have two extra hard drives just for mirroring
but this controller has 4 SATA ports and the case has 4 open bays for storage
devices. For the new HDD I chose to go with the Seagate barracuda Q1 SSD 960,
these are compatible with the 6/GBS SATA that’s also on the RAID controller. The
MTBF for the SSD’s are 1,800,000 hours and that seems to be a bit of time till the
expected failure happens. Total change was 475.76 I would definitely use RAID
hardware better then RAID software just because it works better even though it is
more expensive. I would use RAID 1, just because you can atore data in more than
one place in case something goes wrong or anything crashes. RAID 0 if it crashes all
data is lost, if you need it for speed and you dont mind loosing data then it is a
good set up but not preferred in an enterprise situation. The time it takes all delends
on the disk size. Installation can take a couple of hours or a couple of days
depending how many hours you spend on installing this. RAID 1 can cost a couple of
hundred dollars or a couple of thousands depending on how many and how large. I
chose RAID 1 because it provides redundancy and it provides the most uptime which
is the case at hand. I found one that fit the PCIex4 slot with four SATA slots on
Amazon for $96.99. This RAID controller card advertises that it "supports RAID
configurations of today's fastest SATA 6Gb/s HDD's" and then lists off all RAID
levels, I think it would be a good idea to aim for RAID 10. Because RAID 10 is a
mix of RAID 1 and RAID 0, RAID 10 uses four total hard drives, saves data to two
different hard drives as if they were one, and stripes that data over another pair of
hard drives. This way we can reduce server downtime, and if something went wrong,
such as files being corrupted, then we'd have a backup just in case. Since we only
need four hard drives for the entire company and already have one, I found a 1TB
hard drive for $50.00 on BestBuy. In total, the cost of the RAID controller and the
hard drives would arrive at $246.99. It would take a while to back up any data on
the hard drive already, depending on how much space is being used, but after that, I
don't think it would take long to set up and test everything as all the components
should be compatible with one another. I chose this particular RAID controller as I
was looking for one that would be compatible with a PCIex4 slot while also having
enough connections to support enough hard drives to run RAID 10. There are several
different levels of Raids. The first being the simplest form which is called Raid 0,
which is primary used to improve HDD performance but doesn't add any redundancy.
I would recommend Western Digital VelociRaptor, which is priced around $45 on
Amazon. Another Raid level is Raid 1 is mostly used for redundancy. Raid 1 requires
a minimum of 2 HDD, one that i would recommend for Raid 1 would be Western
Digital Blue priced around $55 on Amazon. Another raid option would be Raid 5/6,
which is used to increase performance, while also adding redundancy. Raid 5 requires
at least 3 drives, while Raid 6 requires at least 4 drives. These are good option
because while using RAID 5 you can lose one disk, and while using RAID 6 you can
lose two disks, and still maintain your operations and data. For both Raid 5 and Raid
6 I would recommend Seagate FireCuda, which can be priced around $50 on amazon.
The last level of Raid would be Raid 10, which requires at least 4 drives. It basically
combines Raid 0 and Raid , which will give you both increased speed and
redundancy. I would recommend Seagate FireCuda for this as well. would suggest
using a RAID card that will work in a PCIex4 slot that will handle four drives. When
I found out that fault tolerance is another word for mirroring, I found that RAID 1
may be the best option for this situation. With RAID 1, files are copied faultlessly
and concurrently, from one disk to another, establishing a model, or mirror. If one
disk becomes defective, the other can keep working. I believe it is the simplest way
to implement fault tolerance and at a low cost. I did find that the downside of the of
using RAID 1 was the performance will hit a slight snag in performance but knowing
your data will be taken care of should something were to happen to your computer. I
have found some options of drives I could use that use on Best Buy’s website that
range between $70 to upwards of over $100 depending on the amount of TB you are
looking to use. I really hope I answered this question somewhat correctly, any
feedback would be greatly appreciated because I try to read all the replies the class
leaves and them to my notes. Solid-state drives (SSD) store data as electrical charges
in semiconductor flash memory. This makes SSDs much faster than magnetic HDDs.
SSD storage capacity ranges from around 120 GBs to many TBs. SSDs have no
moving parts, make no noise, are more energy efficient, and produce less heat than
HDDs. Because SSDs have no moving parts to fail, they are considered to be more
reliable than HDDs.
SSDs come in three form factors:
• Disc drive form factor – These are similar to an HDD in which the
semiconductor memory is in a closed package that can be mounted in computer
cases like an HDD. They can be 2.5, 3.5, and 1.8 inches, although those are
rare.
• Expansion cards – This plugs directly into the motherboard and mounts in the
computer case like other expansion cards.
• mSata or M.2 modules – These packages may use a special socket. M.2 is a
standard for computer expansion cards. It is a family of standards that specify
physical aspects of expansion cards such as connectors and dimension.
• I see that implementing RAID 1 is the simplest way to achieve fault
tolerance, and it is cost efficient. The drag on performance after installation is
substantial, even after execution of 2 HDD. Raid 5 is the most reliable in data
security while level 5 provides the best balance between performance, fault
tolerance, and reliability deciphering a more suitable SATA cable in the case,
would be sufficient. Although, updating windows to the most recent version
would also help with some of the problematic lag. Also, adding an additional
graphics card to the PCIe x 4 slot could benefit the delay in
• a single hard drive using a SATA connection. Purchasing a WD - Mainstream
2TB Internal Serial ATA Hard Drive for Desktops seems to be a feasible
option. The HDD will cost 70.00, An upgrade on the PCIe x 4 graphics card
will be 119.11, it is the MZHOU PCIe SATA Card 6 Port, PCIe to SATA
Controller Expansion Card, 6 Gbps SATA 3.0 PCIe Card with 6 SATA Cables,
Marvell 88SE9215 6-Port chip, Support for HDD or SSD.
RAID stands for Redundant Array of Independent Disks. It’s a way of combining
the storage power of more than one hard disk for a special purpose, such as
increased performance or fault tolerance. RAID can be implemented in software or
in hardware, but hardware RAID is more efficient and offers higher performance
but at an increased cost. There are several types of RAID. RAID 0, 1 and 5 are
the most commonly used RAID levels.
