SCSI is definitely not backdated. The cost part is the only thing that doesn't make it cost-efficient.

I see, thanks....Dun think need a RAID, just a simple mass storage should be able to do the trick.

So There are SATA harddisk casing as well in Storage Studio?

Yah they have all sorts of enclosure for diff needs.

Their price list is here:

U can consider this brand IOI Technology, model FWBU2SATA35D, selling $209
SO u can put 2 SATA HDD inside and either connect to PC as 1 drive or 2 drives. Neater.

1 question for RAID experts, do I need to use the same HDD for RAID 0 Stripping?
Can I use different capacity HDDs?

it is highly recomend to use the similar HDD as performance for different models (capacity) might varies.

Thanks guys! :thumbsup:

I'm using a iMac so cannot have 2 harddisks inside. Can I use those external harddisks as raid? If yes, how?

You pretty much got most of the info from that link. the only item not quite correct is the stripe chunk for RAID 0. Lastest RAID cards like 3Ware only have stripes sizes of 64KB, 128KB, 256KB, etc

RAID 0 - uses 2 HDD - Enhance read and write operation but do not have any fault tolerance

RAID 1 - uses 2 HDD - Mirrors each HDD, good only if it's only HDD crash.. not much help if due to power surge damaging both HDD, etc.. ;p So still better to use an external backup.

RAID 5 - Min 3 HDD - Nice to use, can just rebuild array if one of the HDD spoil.. pretty good except that most RAID cards are sold with 2 / 4 / 8 / 16 ports. Might as well get a 4 port and use 4 HDD..

RAID 10 - Min 4 HDD - Striping is used on 2 HDD while the other 2 HDD is used to mirror the first 2 HDD. Gets the best of the functions of RAID 0 and RAID 1 at the expense of your wallet.. lolx :bsmilie: well it's great if you can afford it.

There are several brands of RAID cards out there. 3Ware is one of the popular ones.. 2 Ports SATA RAID cost around S$270, 4 ports around $500 plus, and 8 ports around $1000....
Naturally there are cheaper brands out there, some are not as efficient, some are pretty good.

There are also software RAID, it comes at the expense of your system performance and not reallly reliable.. avoid those.

To add on.. yes. you can use HDD with different capacity for RAID. However, the RAID will configure the HDD at the max capacity of the HDDs with lowest capacity.

Example:

If you are using RAID 0 with a 250GB HDD and a 300GB HDD - RAID will only use 250GB from the 300GB HDD. Giving you a total of 500GB capacity.

Thanks guys for all the info! Really appreciate it! Thanks a million!

But I really not good with tech stuff....just went to SLS and spent about 4 hours walking around.....totally lost and confused.... with SATA, RAID, IDE etc

In the end, I bought a Firewire HD case and a USB 2.0 HD case(Budget lah) and 2 200gb HDs(Hitachi). Good enough for me lah... 1 as a Work-in-Progress Backup disk and the other as a Archive disk.

what's the largest capacity SATA available now and how much are they? what about second largest? I bought a 400GB disk and that was a year ago.

I can't advise on that, I was looking for just 160gb because its cheap and more that enough for me. I got 200gb because the shop dun have 160gb anymore and I am tired.;p

I got mine for $106 each but its IDE.

The largest should be 700 or 750GB.. can't remember.. but the shops here area still mainly selling 250, 300, 320 and 400 GB ;p

 

[hwchoy]

wow! 700GB now huh. I am from the era of 19-inch drives where 450MB is a big deal. The cool thing is when you spin them up you gotta do it sequentially else you will overload your power and they sound like jet engines starting

when I built my next PC, I am intending to mirror one pair of disk, and a third disk as "manual shadow" backup. 700GB sounds perfect any idea how mch?

 

[Ashleyy]

haha.. dunno the price...

I came from the era where my PC dun come with a HDD.... :sticktong
sigh.. and I had to use the big 5 & a quarter inch floppy... ;p
and some games take up 10 floppies...:bsmilie:

 

[hwchoy]

heehee my time dun have 5¼-in floppies, only 8-inch ones. sometimes paper tape.

actually we used regular audio casettes on the Commodore.

sorry OT too much

 

[TrailsofLife]

My God! USB 2.0 is so slow! 12gb takes 38 mins! Firewire only take 7 mins! regret liao!

hehe.. i had those too.. tape cassettes with green monochrome monitors...
:bsmilie:

Ooops... sorry for the OT ;p

hehe.. USB2.0 is suppose to be faster than Firewire... by the way, if you Mac on USB 1.1 or 2.0? I'm not that familiar with Mac.. If on USB 1.1, plugging a USB 2.0 device, the transfer is still on 1.1

Anyway.. I find that USB speed tends to fluctuate, so can be quite slow at times.. Firewire is more consistent.

why didn't you used internal drives?

 

[TrailsofLife]

My iMac cannot have 2 HDs. So I use external ones. Mine is USB 2.0
