My first experience with an SSD was great, but my second almost soured me to the idea of using SSDs again. I had a new Lenovo Edge laptop a about four years ago I used on my night table and I kept jolting it with my knee, so I decided to buy my second SSD for it, since they'll take a whole lot more bumping before going bad. I bought a new major brand name high end SSD. Because I had to shrink a 500GB hardrive onto it I cloned the Recovery Partition (RP) onto a small disk to store away for an emergency. Then I did some shrinking of the OS partition with a third party CD and after I cloned the OS partition onto the SSD. I put the SSD in the laptop, but I couldn't get the disk to boot, so I went to a Windows 7 installation disk for startup repair, and found I needed the recovery partition. I put the disk with the RP into a USB enclosure, got the drivers installed, and the Edge came to life, or so I thought.
First, I noticed that startup wasn't nearly as fast as I'd achieved with my first SSD in my desktop, barely fast than an HDD at all. I searched the forums for many hours, and tried to find a problem with alignment as several articles at that time suggested. I also played with a BIOS setting or two, but finally just resigned myself to bad speed, but at least having protection from disk failure.
A couple of months later the startup time started getting worse with a kind of double flash on the screen that either sounded or just made me feel something was 'grinding' inside. I called the manufacturer and they asked for some logs or information, I forget which, and decided everything was ok. They suggested I try Lenovo's support and they came to the same conclusion, so I kept assuming things were ok myself. I thought I just had a lemon of an SSD, until one morning the disk completely failed, and the computer wouldn't start at all. I called the manufacturer again, and they had me burn a CD disk, and try to install a new firmware. When that failed they replaced the disk under warranty, and I got Lenovo to send me reinstall disks.
The new installation had the same problem of a slow startup time. On a whim I changed the BIOS from UEFI to a Legacy BIOS and everything was solved at once. I have no idea why that worked and I've never seen an article with that solution, although I haven't searched much since then. I ended up selling the laptop about a year later, because the keyboard is meant for giants, or at least people with bigger hands than me.
I've cloned an SSD into the replacement laptop, as well as two others since, without problems. I just feel this information might save someone from needless headaches.
In my opinion, overall SSDs are worth their weight in gold.
