Hi - ok, I just purchased my first ssd - an intel 320 - 80 gig. I know it is small.
Right now my machine has a 500 gig 7200rpm hd.
I was thinking that I have basically 2 options:
1. install the ssd, move the current laptop hd into an external case and use the usb 2.0 to connect it.
2. install the ssd, buy a 64gig or so flash drive and attach that using the usb 2.0 (the current hd would just be a backup drive for photos/videos/etc)
I was thinking #2 would be better because the flash drive could house the apps so it would be quicker than the current hd.
If we like #2 - is the usb stick better or is a sd memory card better in terms of speed and efficiency?
It depends on the USB key you are thinking of getting.
There are "performance" Usb keys, and then there are "regular" usb keys, for what you want you might want to look into getting a "performance" model.
I know for example - that USB keys take a hard hit if you try to copy something to it...then copy something else it will make the transfer slow to a crawl. As for HDDS - it's not as bad transferring files to and from, but will definately be a bit slower than a USB key in terms of accessing files and such.
Added, just saw your recent post; "no-power enclosure " make sure it has the 2 usb connections.
caution. USB2 is limited in curreent to 0.5 Amps - This limits the device to 2.5 Watts. Not all hard drives (2.5") can be powered from USB2. This was increased to 2 amps for USB3
Thanks retiredchief - unfortunately the laptop has no expresscard slot.
I am not sure what you mean by "make sure it has the 2 usb connections" - I know that the HD works as an external using one of the 2.5" enclosures, I have tried it in the past - this is without power. I do have an enclosure that has power as well so I could use that but preferred not to just so I don't have to keep that thing powered up all day.
1) Some of my usb enclosers cam with a usb cable that has 2 USB connectors on the end that plugs into the laptop, one for data + power and the other just for power. Increases the power provided to the drive.
2) USB 2 spec is for the usb to provide upto 0.5 Amps which limit the power supplied to 2.5 Watts. Some 2.5" HDDs draw more current than USB2 can provide. I've had mixed results on HDDs connected to a single usb port, some HDDs work, some do not.
3) Myself, Normally I use a External power adaptor for the HDDs connected to a USB2 port as even if it does work, it is drawing close to max when writting to the drive. two things can happen when the current exceeds the 0.5 Amp - (A) The port will shut down or (B) it will reduce the 5 V so that power provided does not exceed the 2.5 Watt rating. There is also the outside chance that the port can be damaged
4) USB 3 increased the spec from 0.5 Amps to 2.0 Amps.
