Be aware of one issue with the Crucial m4 SSDs. A bug in the firmware was discovered on early firmware builds (before version 0309) that cause the SSD to brick after 5182 hours of runtime. It is very important to update the firmware following instructions available on Crucial's website. The bug specifically is an error that occurs when the SSD writes to the SMART counter after 5182. Without the update, your computer will BSOD every hour until the firmware is updated.
Even with the "doomsday clock" bug, I still give it 5 stars.
While I have not yet tried fully running down the battery with the SSD, based on the estimated battery runtime I have gained about 25%. I used to see 4 hours with a fully charged battery and a 7200rpm hard drive. Now I see 5+ hours estimated with the SSD when the machine starts up unplugged. And I am sure I can spend time tweaking the power settings to squeeze more life on a charge but I don't normally run for long stretches on battery. But now I supposed I could!
The Windows "Experience Index" that has a max score of 7.9 in each category now shows 7.9 for my primary hard disk transfer rate. I guess this is a good as it gets as far as Microsoft is concerned.
Is an SSD worth the cost: YES. Absolutely.
This fits the bill, but after two drives, I'm going to have to give it one star.
I bought two versions of the drive. One as a kit with a USB 2.0 drive and Apricorn's cloning software. I ran it under Windows 7 and it was a breeze. It was only later that I realized there was an (unbundled/kit) version that had a usb 3.0 adapter.
Transfer and upgrade was a cinch. I did have a couple problems putting the drive in the 7mm slot. Something wasn't lining up right, and I only had this problem with the Crucial drive, not my original HD.
Speed was good, and I got used to it in the two days that I was working with it. Boot time was excellent.
One day, I went to turn on the machine, and I got an error that my system couldn't boot. After several attempts, including removing battery and power, it still wouldn't boot. The bios wouldn't recognize it. I had already done the firmware upgrades to bring it up to 010G, because I had heard of issues with previous firmware versions.
I removed the drive and used both the Apricorn cable, and other sata cables to try and read it, and it just would not be recognized as anything. I tried the same sata cables and used other sata hdd and they were recognized.
I returned it via Amazon, and ordered the same drive, but this time, separately, with a USB 3.0 kit this time.
Same sequence: installed, usb3.0 transfer went much faster, installed the system.
But having read some of the forums, I realized that the power had drained on my laptop, right before the problem. So I ran down the laptop to empty the battery. Then I encountered the same problem.Read more ›
The Crucial m4 is an excellent drive for this task. The 6Gb/s speed allows for outstanding startup times, and all of my programs launch almost instantly. The size is small, but paired with a larger HDD I never find myself lacking space.
This took the cake for my needs. I was able to install Windows 7 Standard onto it as well.
Worked right away, no problems whatsoever.
