About RAID..

Hey guys, i was thinking of RAID in my m9750 recently. i have a 100gb HDD 7200 RPM, And an external USB Seagate 100gb 7200 rpm drive, i heard its possible to make a simple surgery for the USB drive and put it inside the lappy and do RAID, if its possible, can somebody guide me through? thanks in advance

 

Bump..Bump

 

can i get a hand in here?

 

If the external HDD you have is SATA, then yes, you can set them up in a RAID. You will however lose all the data on your current drive, so save anything you want to keep to another PC.

As for setting up the RAID, if you're running Windows XP you will have to slipstream a Windows XP disc to include the driver for the RAID controller.

 

how to slipstream? and yes my external HDD is Sata, also can i just place it in the computer as a second HDD? i mean no raid

 

Question is the external hard drive a laptop hard drive. I was able to put laptop hard drive on desktops but laptops that not something that can be done.

 

the external Hard drive is a "mobile" external hard drive i mean from those little ones

 

Are you sure that your PC can detect the external USB hard drive without drivers ?
If no, could you make a RAID 0 with it ? Because I think you're going to have to format your HD and reinstall windows (and no windows, no drivers for your external HD)..

 

Moreover, if your 2 disks are not exactly the same it's maybe not a good idea to make a RAID 0. Because you're going to go at the lower HD speed of the 2 HD (I'm no talking about 7200rpm).

 

well for your first post yes, the computer detects the USB HDD with no drivers, for the second one, the HDD is 100gb and 7200RPM just like the internal

 

I wasnt talking about the 7200rpm, 100GB.

In RAID 0 half of the data is copyed on one drive and half on the other.
So, if the access time is not exactly the same, you go at the lower HD speed.

For exemple, if you have a difference of 10%. You lose 10% on your best HD. If your gain with the raid is 15%, you have only 5%. On a 10s loading you win 0,5s.
I think it works like that but I can be wrong..

 

what does raid mean and what does it do? too lazy to google because google is now spam fest.

 

RAID 0 = 2 disks with half of the data on each. You can access the 2 disks faster than one with the whole data.

 

i think raid 1 is where you have 2 hard drives and they both contain the same data. this way when one of the hard drives fail you wont lose everything because you have a clone of the original hard drive.

 

thanks mate for the info

would a solid state hdd be faster than raid 0?

 

if you're talking about the flash HDD, yes it's faster, colder and more quiet. But it's also more expensive (realy more..) .

 

yeah that's why i didnt buy that flash hdd they are chargine over $1400 bucks for only 80 gig yikes.

 

Look to see what Samsung is gonna charge for its 256GB SSD coming in September. If it's *relatively* cheap then we may finally see SSD coming into the mainstream

 

if ssd? lol i am gonna catch up with all the lingos soon.

what is ssd? i dont wanna google because google is now spam fest with irrelavent porn.

 

ssd is another name for the flash HDD

 

my both hard drives have identical speed i think, so is it possible to make the surgery on the External HDD?

 

thanks for this info

 

thanks mate

 

Still, none has answered my question about how to do it

video of someone doing it with his m1730.

 

thats just how to put em in the lappy, not how to make them functional

 

it tells you how to set up raid. start watching at 4:18

 

it just mentions the Bios 1-click thing, not the whole proccess but thanks for the link

 

If you can tell me which raid level you want...0 or 1...and what OS you would like to install, i can give you a step by step start to finish.

When i got my M9750 i took the original HDD out day one and put in 2 fresh drives configured at RAID 0.

 

windows XP, Raid 0, but the big question is... if i unscrew the external HDD will it be possible to put it in the Lappy?

 

What brand and model is the external HDD? Just so long as it's a 2.5" sata drive inside your totally fine.

Once you take apart an external HDD that contains a 2.5" drive, you will be left with a normal internal 2.5" laptop HDD. You would then take the empty drive tray out of the M9750, screw the HDD into the tray, slide the now occupied tray back into the M9750 and secure it.

 

well thats what i needed to hear, i unscrewed my External HDD, which is Seagate momentus or something, and gonna do the operation sometime tonight, another question is... is there any possibility just to put on the 2nd HDD with no RAID setup? like two seperate HDDs? i dont want to remove everything i've got on my lappy ive spend Days tweaking it

 

yeah, absolutely.

Just install the drive, and turn the computer back on. Should show right up as a 2nd "Local Disk."

 

yup thanks for the reply, +Rep

 

No problem, let us know if all goes well or not.

 

alright, i'll try to do the operation sometime tonight if i could

 

If you disassemble your external HD's enclosure, you void the warranty.

But if you don't care, just unscrew random screws until it falls apart and you find the HD inside.

Open up your m9750 and plug it in. Backup all your data, slipstream a raid controller into xp and reinstall.

You might be able to do raid1 without formatting...


Note:
Raid0 = split data half and half between two HDs. You effectively double you read speeds, write speeds, and HD space. You also double your chance of HD failure and losing all data on BOTH disks.

Raid1 = copy data to both HDs. You double your read speeds, don't lose anything with write speeds, and don't gain any HD space. However, you effectively half your chance of HD failure because of redundancy.

Choose carefully which you want to use. There are other Raid setups too, but they require more than 2 disks.

 

There is no doubling of read speeds with either RAID0 or RAID1. From what I have read from other posts, the read speed improvement from single drive to RAID0 is rather small-maybe 15% on average. In my opinion it's not worth the trouble.

 

Operation was successful ! thanks for the guys who helped me through this
