Crucial M4 has been discontinued

Maybe this isn't news to many of you, but is to me, the M4 line of SSDs from crucial has been discontinued. The replacement is the M500 series and is a 7.5mm with a 9.5mm adapter.
This is from a chat I had with a Crucial rep:

Gary : Hi, I recently did a cross ship RMA on a M4 SSD and got this reply
Gary : "Thank you for your email. The price you paid is the price of the drive when we stopped manufacturing them, "
Gary : have M4s been discontinued?
Jameson : Yes the M4 has been discontinued.
Gary: Thanks, is a replacement coming soon?
Jameson : We already have the M500 as the new drive.
Gary : Isn't it only a SATA 3GBs?
Jameson : It is SATA III 6GB/s
Gary : OK, thanks Jameson
Jameson : You're welcome, is there anything else I can assist you with?
Gary : No sir, that was it, I had no reply from emails.

News to me. What did you get in return? an M500?

A refurbished M4. With an older firmware, 000h which I updated to 070h.

Yup, been using it for a few days so I could RMA the Samsung 840 Pro.

Hum Gary maybe why my supplier isn't stocking Crucial at the moment. My M4 is working ok at the moment and am wondering if I should get that new one and clone as my main 7 OS for the laptop is on it?

If your M4 is working fine, I'd leave it, they still have their 3 year warranty. Making an image or clone on a HDD is always a good idea.

Did both of these drives fail recently (close together in time)? What happened to them?

Hi there
Why on earth would you want to send that one back --excellent SSD's --top notch performers.

Cheers

The M4 was about a year old, same issue as the Samsung.
