Summary: You can read up on this elsewhere on the Internet and you'll find that many people have had issues with the M4s - apparently its predecessor the M3 was reasonably reliable but the M4 is frequently short lived. That was my experience.
I've used a lot of these and only had 1 fail so far

Summary: I've used a LOT of these in Asterisk/voiSip phone systems. They get a serious workout since they run 24/7 as server drives. All of them have been great, except for one that failed after about a week. So I'm taking off 1 star for that. The performance isn't the fastest.
Summary: I ordered this for use in my Intel NUC which is running OpenELEC. I have had zero problems with it. It works great, and is fast. I haven't done any benchmarking or comparisons, because frankly I don't really care. It works perfectly for my needs, and should work great for any other average use.
It's got some up's and down's.. The down's are much better then the up's.

Summary: Fast reads in the 270's but writes are painfully slow around 55MB/s. I bought this to use with Intel Smart Start technology. It works fine for startup, but if you generally wait for your machine to finish powering down before walking away, you will rack up some significant idle time.
Summary: Solid state drives fits within my Intel Nuc. It has been running without any issues. Only downside is that it is pricey for the storage one gets but at this small size, it's to be expected. I would recommend for anyone with an Intel Nuc.
Summary: 10-07-13: I installed one of these in an HP DV6-7014nr laptop to run as a fast cache with Intel Rapid Store. It had been working nicely for about 6 months. Yesterday, it suddenly was reported dead by the Rapid Store.
Summary: RMA process for failed drive was easy and painless so I'm not taking away and egg for the failed drive. I used this in a new desktop build as a cache drive and am very impressed by the speed. Subjectively it feels almost as snappy as my laptop which is 100% SSD.
Pros: -Not very expensive for its capacity. -Makes a PC noticeably faster when used as a cache drive with Intel SRT -Very small and unobtrusive
Cons: -Failed after a few months, replaced under warranty.
Summary: Always been happy with Newegg til now. It's not they're fault I can't get this drive to work and neither mfg has knowledge to compatibility. But since Newegg wont refund I'm stuck going through Crucial with a drive that might not even be bad.
Pros: It's made by Crucial and fits the mSata slot.
Cons: Neither Dell nor Crucial can confirm if this drive is compatible with the Dell Mini 9 and mine doesn't work. So it's either bad or not compatible, the pin counts line up but Dell states it needs a pata drive. Worst part of all of this, Newegg refuses to refund on a drive I had less than a week.
