The cable that John sells will allow you to use a Toshiba ZIF drive. That 1.8" Samsung ZIF PATA drive would also work. I have used the KingSpec SSD's but already burned up two drives in my LE1700. Great drives when they work, but my data suggests a short life if you are going to use the machine for extended periods of time each day. I was using it 10-12 hours a day. Good luck on your search and welcome to the forum.
