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 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

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

$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

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

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

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

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

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

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

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

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

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

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.

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

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
