They are twice the price because they are usually better tested items.
The cheaper SSD's have a far more limited of number of writes, have
less redundancy of cells (so when goes bad it can use another one) and
are more likely to go dead completely. Most everyone I know who has
used the cheap ones has been burned badly where they lost everything
within a month or two of using.
