I know you passed on the vertex4 but I can say they are faster than my old intel ssd and is holding up really well. Dave also has a couple of them but I believe his are the 256gb ones where mine is only 128gb.

Sorry I can't compare performance or reliability to the Agility 3

Thanks Syber.  Well I have one already and it works fine, so I think I will pick up another one soon.

I think I am going to stick to the Agility 3 again, but might go for the 240GB one this time as the £/Gb is better.  Dunno about these refurbished ones I keep seeing.  Scan has them on a 1 year warranty, worth paying for do we think ?

What's the verdict on those ?

Depends on whether they're factory refurbished, or done by a 3rd party. Beware the3rd party refurbs.

Makes me wonder, though, what there is in an SSD to actually refurbish...

Those ones I linked to are factory refurbished.  I'm trying to find the warranty on a brand new one, looks to me like it might be 1 year too...

This article shows what they have inside Dave : http://www.anandtech.com/show/4346/ocz-agility-3-240gb-review

OCZ drives seem to be a bit thin on the ground at the moment, I see amazon have some:

Not sure if I would go for the refurb, and when I have doubt I tend to err on the side of caution.

Yes, the best price new is on Amazon I think so far in my travels.  I tend to be wary of the refurbished ones too, you might get lucky and get a new one but at the same time you could get one with problems.

Been doing a bit of research on SSD's, seeing as the OCZ drives are very thin on the ground I have found what looks like a good replacement, faster speed than the Agility 3, good specs, reviews and price.

Looks grand    I looked at the Samsung ones you mentioned the other day too, but these seem better.  I think they are cheaper too.

This looks like a good buy at the moment :

I remembered reading about Samsung drive failures a bit back, I did a quick search and came across this article. http://www.anandtech.com/show/6483/update-on-samsung-ssd-840840-pro-failures

article says they fixed the problem, but I would do more research just to be safe

Having never used them drives I wouldn't like to say for sure, I can say that these are good.

I took a look Syber, thanks. It appears that problem was with an older different drive.

The reviews on Amazon are overwhelmingly positive for that one I linked to. Also they are positive over on eBuyer :

One for the wish list, for me anyway.
