I have a wealth of items that need power via a usb port-
fans, speakers, etc. This powered usb hub fills that need
very well - and keeps my usb 3 ports free for items that
need data transmission. It is a very cost effective tool.

 Crucial - P3 1TB Internal SSD PCIe Gen 3 x4 NVMe
Crucial - P3 1TB Internal SSD PCIe Gen 3 x4 NVMe
Basic bootup speeds won’t cut it — not at work, on the go, or in the game. But the Crucial P3 SSD is anything but basic. With NVMe performance that’s more than 6x faster than SATA2 and storage capacities up to 4TB3, the P3 leaves older storage technology in the dust. Get faster bootups, downloads and file transfers, and store all your files, photos, videos, apps, and games with room to spare with the quality and dependability you expect from Crucial.

I have an older machine that uses one of these for the
system drive. It works so well, and is priced so well, that
I purchased a second one to use for system image backups. I clone my system drive to this each month, to
use as a backup. It is a fairly fast process, and provides
a good way to recover if a problem develops.

does a very good job.

I got this drive as an upgrade for my system drive in my
new gaming computer. This drive is as fast as advertised
(see my test results below). At the start of the test it was
at 37deg C. At the end of the test it was at 51deg C, but it
was back to 37deg C in just 4 minutes.
I had no issues cloning my system on to this drive using
Acronis. I have had no issues running my new gaming
computer with this drive in the 2 months I have had this
drive.
This was a good purchase, and has enhanced the
capabilities of my new gaming computer.
