    A bit pricey but more convenient that purchasing multiple drives. Works on Mac and drive speed is incredible.

    Failed after three months of gentle, at-home use – still in its original packaging. The failure necessitated hundreds of dollars in data recovery, and now, the need to buy replacement data storage. After sharing with other professional photographers, I've heard multiple reports of widespread issues with this particular disk within the last few months – sounds like a bad batch. I wish there was a way to get reimbursed for this to purchase a dependable replacement instead. It is not worth the risk to me to try this product again, and I regret spending so much money on it.
