What are the minimum and maximum capacity of the following storage devices?

Floppy disk
Hard disk
Magnetic tapes
CD
DVD
Solid state
Flash memory stick
Memory card

I think for all, the minimum would be 0.

Floppy disk: 1.44MB
Hard Disk: 1,000GB, maybe even larger with the way technology advances.
Magnetic tapes: Unknown.
CD: 700MB
DVD: 4.7GB single layer, 8.5GB dual layer
Solid State: Solid state what? I’ve heard of solid state HDD drives being 64GB, but I’m sure there’s bigger.
Flash Memory Stick: The highest I’ve heard of is 8GB, but it depends on what we’re talking about here.
Memory Card: There are many types.

In Macintosh Leopard can I make a network storage drive LOOK like it’s a physical external device?

I’m trying to use network attached storage SMB drive to use Time Machine. As Time Machine NEEDS a physical external device I was wondering if there is some possible way to make a cifs:// mounted network drive look physical and ‘trick’ Time Machine in thinking it’s physical so it will register. Any input would be great, thanks!

I’ve heard that it is possible to connect to a network drive to a shared drive from another Leopard drive but this isn’t the case at all and I have no physical way to connect to the drive.

Thanks.

No, you can’t trick Leopard into thinking it’s a USB or Firewire drive. I think Time Machine currently is limited to those options, but future updates should expand those possibilities.

I need a good home Mass storage solution?

I have about 1tb of data, probably looking to have a NAS server/setup/something of 2tb

i have 4 320gb HDD’s but HDD’s are cheap these days, i dont mind buying more

Help is much appreciated.

( NAS stands for network-attached-storage )

NAS is a pretty expensive option. Build a cheap machine, load it up with as many drives as you want, 4X500GB or 2X1TB, and put it on your network, use it as a file server. If you’re just using it for data storage then you don’t need anything exceptionally powerful, just disk space.

Server 2003 Tape Backup Issues?

We have a Dell PowerVault 110T (LTO 2) Drive connected through a Adaptec 39160 SCSI Controller and are having constant problems. When it does actually work the device reports alot of time out errors (some of the files we are backing up are 1GB +) but i never thought that would cause such a problem? Are there any obvious things apart from file sizes which could cause the timeout issues with the tape drive??

* f you are backing up to a network share, ensure the UNC path you are backing up to is always accessible.
* Ensure the drivers for the media of the backup destination are up to date. Contact the manufacturer for information about updating your drivers.
* Ensure there is no excessive activity on the device you are backing up to.
Ensure the disk to which you are backing up has adequate disk space to hold the backup.

What is meant by SATA and PATA RAID?

And what is meant by NV RAID 0/1/0+1/5 JBOD when relating it to SATA RAID? What does the 0/.mean; what does the 1/ mean; what does the +1/5 mean; and what does the JBOD mean? I’m trying to learn here guys and gals. Please help me understand.

And what is meant by NV RAID 0/1/0+1 JBOD when discussing PATA RAID?

What does SATA RAID and PATA RAID mean? And how are they different?

The reason I ask this question is because I’m looking at two different mother boards; one has SATA and PATA RAID capabilities……the other mobo does not list PATA RAID……does this mean the mobo that has PATA RAID and SATA RAID is the better mobo?

Please explain. This is very confusing.

SATA and PATA are just IDE hard drive interfaces. SATA (Serial ATA) is newer and uses a cable that looks something like a telephone cord. The older PATA (parallel ATA) drives connect via those flat ribbon style cables. The only difference is the interface, the drives themselves are exactly the same. SATA RAID is just RAID using SATA drives and PATA is just using all PATA drives. Most RAID controllers allow you to mix them, so it doesn’t even really matter.

For the different kinds of RAID setups, see here:
http://en.wikipedia.org/wiki/Standard_RAID_levels

Btw NV RAID is just Nvidia’s raid controller via the Nforce chipset and it supports RAID 0, RAID 1, RAID 0+1, RAID 5 and JBOD (just a bunch of disks).

What is the best solution to create a home server with UpnP streaming and storage with multiple devices?

Hi guys,

I want to find out the best solution for what I am looking for. I have a Macbook, a Macbook Pro with Vista and Leopard, and a PS3. I would like the ability to access the storage from any computer (Vista and Mac side), and be able to open and store files from the computer through our network. Also, I would like to support media streaming with the PS3. I know of a few suggestions, like getting a NAS device, or using a USB hub that connects to the network, then attach all the drives I want. It would be nice to be able to access the server from the web pretty easily, and the fastest speeds possible. I appreciate all suggestions.

Only you will know for sure. My suggestion would be for a Gigabit NAS. If you need to access it from the web (Very dangerous…. Don’t keep naked pics of the wife on it of you do!), you can forward port 21 from your router (Most NAS support FTP). Look for one with cooling fans, as heat is a big Hard Drive killer.

AWOL: An Adaptive Write Optimizations Layer

Operating system memory managers fail to consider the population of read versus write pages in the buffer pool or outstanding I/O requests when writing dirty pages to disk or network file systems. This leads to bursty I/O patterns, which stall processes reading data and reduce the efficiency of storage. We address these limitations by adaptively allocating memory between write buffering and read caching and by writing dirty pages to disk opportunistically before the operating system submits them for write-back.

JESUIT - gadget @ TTS -Ep32- Samsung Solid State Drive

http://www.TheTechStop.net

This week we get uberGeeky once again with the Samsung SSD. This Solid State Drive is built on Samsung’s NAND flash memory technology to provide you with the highest performance possible in a data storage device. It also provides an unprecedented level of power and thermal efficiency, durability and longevity that is second to none.
We run the SSD through its paces, throwing the latest benchmarks at the unit as well as a few real-world scenarios. With a SATA II interface, 100MBps read / 80 MBps write, 2.5″ and smaller form factors, as well as the industry’s best flash technology, the Samsung SSD might be just the thing for your notebook, desktop or server.

We also take a look at the TIX clock from ThinkGeek as a way to add some uberGeek style to your den of nerdiness — Stay tuned!
