MacBook Pro 13″, macOS 13.2
FYI, SSDs don't spin as there is no mechanical movement within them. How are you measuring the speed of the external SSD?
What is the exact make & model of the external SSD (provide a link if possible to the product page)?
How is it connected to the Mac?
What is the exact model of the Mac and version of macOS? You can get this information by clicking the Apple menu and selecting "About This Mac".
What file system is being used on the external SSD?
Make sure to disconnect all other external devices in case one of them is causing a problem. Connect the external SSD directly to the Mac. If you must use an adapter, then maybe try another adapter. Try using another USB port, if on a laptop, then on the other side of the laptop.
If you run the third party app EtreCheck it will provide the answers to some of these questions as well as allow us to see whether any third party installed apps may be interfering with the normal operation of macOS and also provide some information about the performance of your Mac which may be related to the SSD speed issues.

I use external ssd with box usb 3.1
Before the speed were 350mb/s now is 40mb/s
Silicon power
SSD 512GB 3D NAND A55 SLC
Cache Performance Boost 2.5 Pollici
SATA III 7mm (0.28") SSD interno
I have the mediacom hub MB-C301 and box mediacom M-HDSB3AS
I think it's connected to usb 2.1 but in reality it can work in usb 3.1 I think it's the wrong driver maybe during installation
The System Profiler is showing the SSD is connected with a max transfer rate of 480Mb/s which is USB2. It may be as simple as the adapter, cable, or dock/hub/enclosure which is connecting the SSD. I tried to look up information about that JMicron USB chipset, but I'm not getting any specifications for it with a quick search. Make sure any adapters, docks, hubs, enclosures are USB3.
I cannot find any information about this, if this is a router, then it may only support USB2, I never recommend connecting drives to the USB ports of routers:
mediacom hub MB-C301
But this appears to be USB3:
mediacom M-HDSB3AS
what I can do for resolved because the box and ssd are 3.1 before were 300mb/s after I have reinstaller Ventura for some problem
ssd is 512 gb have 300 gb free
macOS ventura 13.2.1

USB 2 has a max speed of 50MB/s (probably more realistically closer to 40MB/s).
can I change some configuration
M-HDSB3AS is box sata after there is hub all is usb 3 MB-C301 hub its possible change the driver from ssd
ssd external too much slow
