Most realiable ssd

thanks but any proof? Personal opinions sounds more realiable when some data is presented ...I heard Plextor M5 is more reliable but how true is that?

Hi Johnny,
I have a 512GB Crucial m4 SSD that has been running 24x7 for a year with no problems. However, it was important to upgrade the firmware to achieve that reliabilty (this article discusses it). The m4 is now obsolete and its replacement is the M500, which is available in four capacities (120GB, 240GB, 480GB, 960GB):

I've been on many threads in the past year about SSDs here at EE. I suggest that you do a search for "ssd" and review some of those threads. Many experts have had very favorable comments about the Intel SSDs.

In terms of "proof", have a look at this:

The problem is that it's 10 months old, but other than that, appears to be an excellent statistical survey. Regards, Joe

Study and Tests on Samsung:

Our best experience has been with the Intel SSD drives.

The Intel 335s and 5xx series drive, and the Crucial M500's are the only units I recommend these days.

I've seen FAR too many failures with OCZs -- I wouldn't buy them at any price.    I've also seen a few failures with assorted other brands, but have NEVER (knock on wood) had a failure in any of the Intel units I've installed for myself or others.

i also use intel SSD's - no problems yet

On a consumer level I know the top ranking SSD drives were Samsung and Intel.  The Samsung 840 ranked highest for speed and reliability.  Intel (I think 520 series?) was also a contender but did not match the speed capability of the samsung but is renoune for its reliablity when they switched to the SandForce controller.  

I think a Vector drive and SanDisk were also some competitors but as a brand comfort level I have always been happy with Samsung and Intel when it comes to SSDs

Intel and Samsung tend to be regarded as the most reliable from consumer reviews (from NewEgg, Amazon, etc.) and publication reviews (and having worked with both I've found them to be very reliable as well).  In terms of reliability studies the Samsung study/test posted by NRhode is a good resource.  Additionally, Tom's Hardware has an article regarding return rate of SSDs (Intel specifically) from various data centers / providers.  The article is from 2011 and focuses strictly on reliability of Intel enterprise grade drives (overall and versus HDD) but is noteworthy:
