all SSDs have reserve blocks. if you get a damaged block, it is replaced with an undamaged block. Sometimes it is replaced if the block is no damaged because the controller is trying to make sure wear leveling is right (all the blocks wear at the same rate, so the wear is evenly distributed) A lot of programs don't understand the SSD controller functions. And rightfully so. Almost all SSD controllers from different brands work differently, so no program could be expected to know that. So, all the program knows is 2 blocks were replaced, it's assumption is a bad block, which is not necessarily the case. That is why they all have blocks in reserve. You will want to replace the SSD for a newer one before it wears out.
Thanks everybody , it's really over my head and i was just curious . The Intel toolkit shows no issues with the drive , health is good , SMART is good etc..
It's brand new and installed only a few days ago so i was concerned when i saw bad blocks .
Got around to getting mine tested after changing my system to GPT and UEFI mode. Made a huge difference over MBR it seems.
Yes, it uses ram. The only real problem is all the tests are testing the ram cache not the SSD. So, the numbers are great, for benchmarks, It really does nothing for actual usage. I've run mine every way you can possibly run them. The problem is that sata III is maxed out right now. The limitations of sata III have been reached and no matter what the numbers say, about 500MB/s is all the real world sata III is capable of carrying. If you look at the newer boards, the high end ones are coming out with sata express which runs off of pcie lanes instead of sata ports in order to overcome sata limitations. I think some are running 1 SSD off of 2 sata III ports, but I'm not sure about that part. Just like USB 3.0, there is the theoretical speed, but in real world, you won't get even close to it. I've tested it running it from 1 SSD to another SSD, and the limits are still there.
The sata limitations are why the new SSDs coming out like the Samsung 850 Pro are really no faster than the 840 Pro, because of the sata limitations. Running it over pcie lanes is the only way they will ever be faster.
