Crucial SSD performance mystery

In the specifications of the Crucial MX100 it says:

Performance at all capacities represents a significant improvement over M500

Yet the specs for the write speed of the M500 is significantly faster write. What am I missing.

MX100 specs



M500 specs

Thanks for the link. Interesting numbers. Looks like a wash. Based on that I would go for the cheaper model.

I took at the 100 series has more features :/
One being power consumption which the 500 series does not list ?
Newegg's comparison which the 100 is on the right side,
iops shows different than you posted on the same model m500 240gig and mx100 256gig
Attachment 341103

Thanks Mike. Interesting data. The 1.2 million hours for mean time to failure are pretty impressive. I don't think any spinner would hold up that long.

To add insult to injury Amazon dropped the price on the mx100 256 a day and a half After I bought another one
Now at 99.00 same as the m500

I got the M500 for $89 - a couple of weeks ago from Newegg. But I need another one for a new laptop the wife just bought for herself (that's #4).

I now have my eye on a mx100 128gig same spec's and that cool hot swap case TopGun posted yesterday
This will definitely be a black Friday purchase if it breaks bad

Not sure about the hot swap case if it only esata or if it comes with a separate data and power receptacle as a ssd would have on it :/

I am not sure what that hot swap case was good for. If you stick it inside the box into a 3.5" bay, then there is not a lot of hot swapping possible. If you attach it ouside on eSata, then I would prefer an enclosure like this one. I have two of those - eSata/USB2 and USB3/USB2. They work very well.

Well Dino did say it has straight through double male connections it sounds like a better or more normal way to connects the ssd's ?
That esata connection has never been used but this machine is pretty old now it could be corroded ?
I could always make a box for it and add a fan if need be even though my external hdd case doesn't have a fan on it but does have allot of holes for heat to escape :/
