Is 16Gig Usb Drive high speed & compatible XP

  prince midas 11:26 10 Nov 2010

I have been using a 4Gig Usb flash drive on my XP desktop & thought about buying a 16 Gig one around £29 with a speed of aound 4.5 mbsec.
But in Currys they have a £44 one with a speed of around 18.5 Mb.persec.Currys do not know if it would work on mu USB XP pc,any comments.

About your proposed 16BG purchase - If your USB drive is formatted in FAT32? (Most are.) The maximum file size supported in FAT32 is 4GB.

Format the USB stick NTFS or find a way to keep your files under 4GB in size.

Be careful about specifications. The read and write speeds are different. When comparing speeds you need both figures. Unscrupulous suppliers may mention the higher value and omit the lower one.

4.5MB/sec would be classed as slow. You can get these from around £13. If you want faster drives you pay more., and uk are good sources for cheap USB flash drives.

USB3 devices are becoming available. They are backward compatible with USB2. USB2 has a practical data transfer limit of around 30-36 MB/sec (theoretical maximum is 60MB/sec). I have seen USB3 devices rated at 240 (read) and 184(write) MB/sec.

My 4GB usb2 drive is set to NTFS.
So according to this I could buy a 16GB which should run on my XP Desktop.
But would I be able to buy a 16GB ultra fast drive or would it still run at the same speed as my existing 4Gb drive or would it work on a faster speed or what,in other words would I be wasting my money.

USB 2 ports "can" transfer data at up to 480Mb/s

Without going into any technical detail, USB is broken up into three speed groups;
Low Speed USB1(1.5Mbps), Full Speed USB1.1 (12Mbps), and Hi-Speed USB2 (480Mbps)

Not forgetting USB3 Superspeed at 4.8Gbps

What make & model is the Currys one please? I'll help you determine if it's compatible with XP or not.

If 18.5Mbps is the actual write speed (not quoted), it's very good for a flash drive if you ask me.

The price is a bit steep for a 16Gb one though - branded examples for £15 or less: click here & click here. G

I will have to go to Currys & find out.The Sandisk one you mentioned appears Slow.

Is it a Sandisk Ultra click here by any chance? It's the only 16Gb one I could find that's available for the ~£44 price you mentioned. But it doesn't specify write rates.

If it turns out to be the one, don't buy it from Currys as it's available for ~£15 lower at online stores - e.g. click here, click here & ~£25 lower at eBay click here. G
