Ive ordered the 2nd one as its slightly cheaper but should I change my order:confused:
 
Crucial and Lexar are the same company, it might be that the Lexar is a grey import so warranty could potentially be an issue.

Ah thanks. The 2nd one that Ive ordered (Lexar) says it has 3 Year Limited but the read speed is slightly slower at 415 MBps instead of 500:confused: I think thats ment tobo 415mb though.

I'm not sure what the implications of grey imports are. Does this mean it could be fake, or if not fake, might not work as well as a crucial one? The speed of 415 Mbps doesn't sound promising if it's meant to be 500Mbps right? Does anyone here have experience of Lexar products?

edit: Looks to me like Lexar are bone fide and own crucial? http://www.notebookreview.com/default.asp?newsID=6102

It'll be real, but it will have been sold for another market but imported into the UK. Manufacturer's tend not honour the warranty if this is the case.
 
Ah I see, ok. What about the speed of 415 Mbps when the same model is being advertised as 500 Mbps on other etailer sites? I've checked the firmware update on the crucial site and it mentions what the firmware improves but nothing I could see about increasing write speed.

Write speed haven't changed since launch. The way the drives handle writes is down to hardware design rather than software limitation.
The 64GB SSDs will do ~90MB/s of writes, plenty for normal use.
The 128GB and 256GB are faster still due to more channels, the 512GB is roughly the same as the 256GB.

The reads were improved with a firmware revision from 415 to 500 as you say.
 
If I remember correctly it was firmwire 0009 that gave the 20% speed boost. Just flash it to the latest one and the speeds will go up :). Very easy to do as well, just a simple exe file and takes about a couple of minutes.
 
Thanks for the info Orcvader.

Thanks. My mistake btw, I meant to say read speed, not write.

So really, everything will be fine for Phil, it's just the warranty that may not be honoured.
