Data is the RAID level of choice for operations that require tolerance and
rapid disk speeds.In order to install 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 xx 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.
