Customers say
Customers find the SSD’s speed impressive, with one noting it improves system backup speed by 100x, and appreciate its quality as a solid backup solution. The capacity receives positive feedback for its large storage space, and while some find it worth the price, others consider it overpriced. The drive’s reliability is mixed, with some reporting no issues while others mention it fails without reason, and connectivity problems are common as it frequently disconnects from computers. Heat retention is also a concern, with customers noting it runs warm and never cools below 40 C idle, while data loss is a significant issue as the drive corrupts data.
