USB2.0, Why is a LACIE 7200RPM drive faster than a Samsung 840PRO in an enclosure? Testing drives for backup

Hello,
Confused. Backup up data. I thought SSD's were faster than spinning drives. I have a case where USB3 drives are connected to USB2 ports. The spinning 7200 RPM drive is faster than the SSD in the enclosure. Both drives are setup for performance in Device Manager. Connect to the USB3, the SSD is much faster but this is an old server and have not installed a USB3 card in it, yet. What am I missing? Is it the SSD enclosure is from Sabrent.
Thanks

the ssd is probably sending the information too fast for the usb2 device. Connecting an SSD via USB2 is a waste of money.

There shouldn't be an appreciable difference between the two when connected via USB2 -- the bottleneck in both cases is clearly the USB2 interface.    The rotating platter drive undoubtedly has a buffer that's filling at full USB2 rate, so there's NO advantage of the SSD in writes, and only the initial seek time advantage for the SSD in reads.    If the apparent speed is better with the rotating drive, then that's likely just a difference in the way the USB3 interface is adjusting to the USB2 connection.

the Lacie drive is an entity, made for this connection, with the usb interface integrated , so i would expect it to work perfect.
as said - with the SSD you have the ssd interface that must adapt it's protocol to the much lower USB 2 speed.
(you will probably have the same problem with USB 3, it still is much too slow for an SSD - you should connect it directly to a sata port -  and best a 6 GB one)

As garycase said the bottleneck is the USB 2 port for sure. How much difference are you seeing and what kind of situation is it? A good 7200 drive can hold its own in sequential writes.
