Hello!

I want to buy a safe external disk for my Lenovo T520 laptop. I've been looking few hours already on the internet, but I'm still not sure what to buy!
The disk should have following feature (listed from the higher priority):

- Safe ! It will be used for data storage, but also for data backups . I like traveling, so it must be SSD or HDD with some kind of free fall sensor protecting it from fall, hit, shock. I think that a good, solid enclosure with rubber protection would be desired.
- FireWire port. I have Lenovo ThinkPad T520, it doesn't have any USB 3.0 port nor eSATAp ( Power over eSATA ), so FireWire is probably the only good option for me which is fast and does not require external power source. Also the enclosure of disk rather should have USB 2.0, so it allows to connecting the disk to some older laptops which don't have FireWire. I am not sure if such solution requires external power source or second USB cable ?? I might be wrong, but I think that using AC for external disks is not convenient, is it ? I have normal eSATA, so maybe this is also an option too, I'm not sure.
- Low price ! It should be relatively cheap. I'm not giving any limits, because prices in the country I live (Poland) might be different. Probably normal HDD, because SDD with 256MB of capacity are too expensive for me.
- Relatively fast. I use SDD 128 GB as a main disk in my laptop and I REALLY appreciate it's speed. It is Micron ATA C300-MTFDBAK128M , not one of the fastest, but I'm still really happy with it.
- Silent. I don't like any strong vibrations as it feels that hard disk is not safe when it's all shaking.
- Minimum 256 MB of capacity, however a bigger one would be appreciated.

Thank you for you suggestions :)
 
Just so you know, Most 2.5 inch drives should have some form of free fall sensors as well(and WDC[others may do this as well] ones seem to stay parked as often as possible[8 seconds of inactivity and even mid activity if the cache memory can be used for a bit] preventing head crash).

I had a look at WD and it looks like that don't mount free fall sensors anymore. There is no such information in specifications on their website. Can you recommend any other disk with FireWire and free fall sensor? Is there any?
 
LaCie is almost never cheap due to being "designer" devices. Some are not too bad for price, but you pay for designer and in this case rugged. They do have a 500 gigabyte version for less if that is enough space(with the current sale if you are in Canada, Its not too bad at 150 for the 1TB version. The 500 is 120).

I have never used an adapter like that to be honest(last USB to anything I used was USB to IDE and it worked fine as long as the drive was set to master). It is best to read reviews on the one you want because it would suck to have a drive not work with it properly.

Does your notebook have an expansion slot(Card Slot/ExpressCard style)? A USB 3.0 card may be a better option.

Thanks a lot, NukeMaster, you are very helpful. First of all I came to the conclusion that I don't like and I don't trust magnetic disks (HDD) if they are portable at all! Also I read user reviews about that LaCie disk and there are cases that it dropped off a table and broke. I am not surprised. Therefore I want a solution based on SSD or other kind of non-magnetic disk, even if it's more expensive that I was expecting.
Now I see two solutions:
1. ExpressCard with USB 3.0 port + external SSD disk. There are much more of USB 3.0 version than FireWire version and they are cheaper.
2. To buy an internal SSD disk + disk enclosure with many ports like this one:
Welland ME-940U
and mount the disk inside.

The second solution seems to be quite cheaper and more flexible, because I want to easly share data between my computer and other computers. A question to exprerts like you: will this Welland device (or similar) support an internal SATA 3 disk? In it's description there is an information that it supports disks with SATA 1 / SATA 2 interface. Will the disk automaticaly slow down to the speed of SATA 2 ? Alternatively, is there SATA 3 to FireWire disk enclosure on the market? I couldn't find any. Thanks!
 
I am almost sure all revisions of SATA will pass the speeds of Firewire 400 anyway(peaks about 50 megabytes a second).

I have not run into issues running a SATA III based SSD(Crucial M4) in my SATA II based media center. In the old days, some of the SATA controllers(Via and Promise) had issues with SATA II drives but it was fairly rare on newer hardware.

There is no such thing as a safe drive. They all fail at some point. SSD's are more immune to vibration and drop damage than hdd due to their lack of moving parts. OCZ has a video of them batting one of theirs into the outfield and then connecting it up and it still worked! of course ssd's are more prone to just suddenly stop working than hdd's...

perhaps an enterprise grade ssd.
