Yes that's why i'm staying on dumpling. I'll then switch to giant.

Don't use the crucial ones. Yes i was happy with them. But they suck 
just after getting a constant load on them.

Try running seq. fio on them with 4MB blocks. You'll see they'll not 
even work for a single day. Speed will drop to 40-80MB/s. Same applies 
to the S3500. The S3700 works better or a Samsung SV843.

Greets,
Stefan
