Question ADATA external SSD speed capped at 3mbps

[greenjelly1]

Hi, I have an ADATA ELITE SE760 External SSD for around 4 months and after 3 months of using, the speed starts to drop from 300 mbps to 30 mbps and now 3 mbps, did I buy a faulty product? If not, is there any way to fix this issue?

couldn´t find the "elite" version, are you sure about the model name?

other than that, try a different USB port and cable and another system

check the SSD with the adata toolbox

Yes, that's the name written on the box

other than that, try a different USB port and cable and another system

I can't try this option right now but I will make sure to try it out when I have the chance

check the SSD with the adata toolbox

After I installed the toolbox, the model name is ADATA SE760, but it's categorized as a HDD?

eventually update the firmware if possible
backup important data if needed

It said that I already have the latest firmware version

... the model name is ADATA SE760, but it's categorized as a HDD?

My 2TB Crucial X6 portable SSD is showing up as a "USB Attached SCSI (UAS) Mass Storage Device" in Windows Device Manager. I stopped installing Small Computer System Interface (SCSI) cards in my computer 18 years ago, but the term persists.

Don't worry about archaic naming conventions. You know it's an SSD made from solid (hard) components, so it doesn't matter if the Toolbox characterises it as a hard disk.

How full is the drive. If it's nearly completely used up, it's bound to slow down. It's a generic term and possibly the Toolbox can also be used to check spinning disks.

Is TRIM supported on your SE760, or does the SSD's firmware support "housekeeping"?

Are you transferring or deleting thousands of small files. These things slow down file copying.

The drive is 50% used up. The toolbox is for internal SSD when I asked their customer service.

I don't really know about this, is there any way I can check it?

I do transfer small files fairly often, but when I transfer large files the writing speed is slow too.

If your external SSD and Windows both support UASP, the OS may be able to "clean up" blocks of deleted data on the external drive. As the drive fills up, especially past 80%, it will slow down.

Another important thing to note is like eSATA, UASP makes TRIM support possible for external SSDs but it still depends on support from all the SSD controllers and bridge chips used in the SSD besides the operating system. Although UASP enables USB drives to use the SCSI command set, SSD controllers use the SATA command set. So the OS needs to support not just UASP but the SCSI UNMAP command (counterpart to ATA TRIM) and the USB-SATA bridge chip needs to be able to translate the SCSI UNMAP command to ATA TRIM properly.

If TRIM is not supported and the ADATA drive's firmware does not support local housekeeping after you delete files, data transfers may slow down over time.

You could try a Security Erase (see page 13 in Toolbox user guide) after backing up all data. This will restore the drive to its factory default state.
