Question about G-Technology 1000GB Raid 0 Triple Interface (WMM380979)

1 Answer

Speed of 1T Raid

I have your new 1T raid product and it is a nice piece of equipment except for 2 items

1) it is substantially slower than any of my WD hard drives. Is this a characteristic of the Raid-2 configuration? I suspect it will not work well as a scratch drive for FC Pro as I had intended.
2) Is there a setup to enable the drive to spool down after a period of inoperation, or do you have to physically turn it off?

Sorry,

I’m not about to pay for support on a brand new product. If the company won’t respond to my request for input, I’ll simply return the raid for credit.

Thanks,

If the failed hard disk drive is replaced with the exact same capacity, RPM and make of hard drive, then the array can be rebuilt. Raid 0 cannot be rebuilt as each drive contains half of the data, If RAID 1 then can be rebuilt as data on each drive is an exact copy. However if combination of RAID 0 and RAID 1 then can be rebuilt. It's best really to handel this hands on, I recommend taking it to a computer technician especially if the information on it is important.

Thanking you

Tip

Implementing RAID 1 in Windows Server 2003 using VMware!


This is a simple tutorial about creating a RAID 1 in VMware for IT people. VMware, well I think you know already about Server Virtualization.Its a well known product.
Let's discuss about some of the techniques related to Load Balancing or Fault Tolerance.....The Disks here used are Dynamic Disks.
RAID - Reduddant Array of Independant (Not much Inexpensive these days. That term suites no more) Disks. There are two types of RAID:
  1. Software RAID - Implemented via the OS or with the help of a Software. Not much efficient however.
  2. Hardware RAID - Hardware level RAID. Much more efficient and Fault Tolerant.

The idea to use a set of disks or an array is to increase the performance (Load balancing) and provide Disaster Recovery (Folt Tollerant).
RAID 0 - StripingThe fastes of all the RAID configurations. This is known as Striping. Striping is the process of Writing data Sequentially to or Read from more than a single Hard Drive (or a Storage Device).First the data is broken up into chunks or blocks. Then the writing process will be accomplished. The process of writing will be done Simultaneosly onto Strips. The performance of reading and writing increases because all the Heads are working all the time
RAID 1 - Mirroring,DuplexingAs the name implies, it creates a Mirror of one Disk onto another. Data will be written to Both the Disks. So if one disk fails other one can be mounted or it can be used to Restore data.There can be a deadlock how ever. The Disk Controller. RAID 1 uses a Single Disk Controller thus a Single point of failure.We can avoid this easilly with the use of Disk Duplexing which means usage of 2 Disk Controllers.
RAID 2 - Striping with ParityThis is similar to RAID1 but with an added feature known as Parity. One disk - typically the last one - is used to store somethings called Parity bits. With the use of these Parity Bits, the lost data can be easilly generated. This uses Logical XOR Operation. When writing, it XORs every data written onto HDDs and stores in the Parity Disk. When one Disk fails, thet PD is XORed with other Data bits on the functioning Hard Drives. This is a very effective technology in terms of Fault Tolerance. But Performance is pretty low.
RAID 3Similar to RAID 2 but instead of using Strips which are in Bits this technique uses Strips in Bytes. That increases the performance over RAID2.
RAID 4Strips data (Blocks) and uses a Parity Disk. Requires at least 3 Drives. Not widely used.
RAID 5The most popular method. Requires at least 3 Disks. Disks are used to store Parity data as well for each perticular drive. Data Stiped in Bytes (uses block-level striping with parity). Supports Unlimited number of Drives. Failure rate Drops when the number of devices increas.High speed reads can be performed. But writing is pretty slow in this approach.
Note: The non-standard RAID levels 5E, 5EE and 6E extend RAID 5 and 6 with hot-spare drives. Other non-standard RAID levels include: RAID 1.5, RAID 7, RAID-DP, RAID S or parity RAID, Matrix RAID, RAID-K, RAID-Z, RAIDn, Linux MD RAID 10, IBM ServeRAID 1E, unRAID, and Drobo BeyondRAID.
So how are we going to implement such a structure in VMware?That is quite easy. This is an example of Disk Mirroring. Each disk has to have Similar Capacity.
  1. Click on "Edit Virtual Machine Settings".
  2. Click on Add ->Next-> Create new Hard Disk.
  3. Select SCSi.
  4. Give a Suitable Disk Capacity for new Disk.
  5. Give a "Name" and Browse the storage location.
  6. Click on Finish.
  7. You have to Repeat the steps to create the number of Disks that you require. You have to have 2 Disks. Do not use the Main Drive. Use Separate Disks.
  8. Click on OK.
  9. Click on "Power on this Virtual Machine".
  10. After booting up the machine, its the time to implement the Mirrors.
  11. Log in.
  12. Right click on My Computer and select "Manage".
  13. Click on "Disk Management".
  14. Get the "Convert Disk Wizard".
  15. Select the 2 disks (tick on the check boxes).
  16. Click "Next -> Finish
  • Implementing RAID1
  1. Right click on the Disk n which your first added drive (n = the number).
  2. Select "New Volume".
  3. Select the option "Mirrored".
  4. Click on "Next".
  5. Add the Disks from the left hand list box to the right hand list box (the two drives that you have created).
  6. Click on "Next".
  7. Assign a Drive Letter.
  8. Format using NTFS. Make sure you provide a "Volume Label".
  9. That's all what you need to do!
  10. Wait until the Volumes get formatted and Synchronize.
  11. Implementation of the other technologies are similar to the above procedure.
Hope you would enjoy this tutorial.Thanks!

Backup slow


Hi,
You don't specify whether previously on your USB it was the same lacie external or whether it was a different external drive. It sounds like you were using a different external drive, most likely a single drive.
You've specified that you've got your lacie setup in raid 5. Raid 5 gives a very good read spead and a good redundancy for incase a drive fails, however it's write speed is very very slow.
It will be much slower than a single drive on USB for writing to it (i.e. backups), but you should see a huge performance boost in reading from the drive than your previous usb.
If you need it to be faster, you would be better suited looking at configuring it for one of the following raid setups:
Raid 0: striping (not recommended for backups) - data is split over all drives, however if 1 drive fails you lose all data.
Raid 10: striping + mirror . half the drives are striped (like above), but the other half mirror the striping half so if one drive fails there's a backup of it. You only get half the disk space though, so if you have 4 x 1Tb drives, then you'll only get 2Tb of space.

Nas SCM400 not working


The reason that it goes into recovery mode is because RAID5 is not striping so it has to rebuild the drives to be compatible with RAID5. I used 1TB drives and the 'recovery' took about 16 hours. It would be faster on smaller drives.

This is not a fault in the design, it is how RAID5 works.

Different RAID configuration?


Hi,

The first point to note is that this unit does not support more than 1.6TB total disk. (4 x 400GB drives) This is stated in the manual which is on the CD that came with the unit. You cannot configure a mix of RAID1 and Linear (JBOD) drives, so you plan will not work.

Hello!


I saw on ebay they had some Brand New Diskless versions and One Used Working one. I know it is not a fix but a lot cheaper than the $1200-$1500 they used to be.

Raid 5 crashed


Hi Chris,

How many drives are part of the array and what type are they? Are the drives making any unusual sounds like clicking or screeching? If not, then you should be able to recover the data. If the drives are making clicking sounds, you will probably need a professional data recovery service that specializes in Raid 5 data recovery to help you.

If the controller shows that only 1 drive is bad, you should be able to rebuild it by replacing that drive. If the controller shows all the drives are bad, then it is most likely a problem with the Raid 5 controller itself. In this case, you could try putting the drives in a working version of the same enclosure/controller.

Check the obvious also, like loose connections to the drives. Whatever you do, dont force a rebuild as this will probably result in permanent data loss.

Hard drives freezing up


Damaged drive controller on HDD a possibility. Pull drive and test as a slave to rule out a bad RAID controller. Let me know if the drive is failing under SMART setting in system BIOS upon boot.

Help please to restore the failed raid


Well if your data is gone at this point, you mines well just proceed with rebuilding a new RAID 5 set with your replacement drive. Even if one drive fails in a RAID 5 set, your logical drive should still be accessible. Goodluck.
