Question Tricky issue with new SATA SSD

Hello good people.

I ordered an SSD a few weeks ago from AliExpress for external data storage. It was a 512Gb SATA drive SSD. Once I received it, I viewed the SMART data for the SSD. Everything checked out and the health was good. I used CrystalDiskInfo - I'll share a screenshot of the SMART data here. I performed a speed test on the SSD. The speeds were exactly as advertised.

The challenge I have is that when I try to torrent old files to the SSD, the data often gets corrupted. Once I disconnect the drive and reconnect it. It's quite interesting really. If I copy files sequentially to the SSD. The files remain intact. I've tested it several times to be able to recreate it.

I've tried fixing the filesystem using CHKDISK on windows. I've inspected the drive on Linux. I've tried a different USB data cable with the SSD. I've tried a different USB port as well. I've tried upgrading the firmware on the SSD (which corrupted the files that I had on it) but the issue persisted.

I've done some research to confirm if the torrent client that I use - Qbittorrent has a bug or something similar - but I've confirmed that Qbittorrent would treat a SATA SSD in a similar fashion as a SATA HDD.

I probably should have gotten a Kingston SSD.

Can I get some technical regarding the drive? What is the reason for this incidence? If this isn't the right community to post this information, I apologize and ask to be directed to the right community.
Thank you for your help and time.

Primary mistake.

"The challenge I have is that when I try to torrent old files to the SSD, the data often gets corrupted. "
Not sure what you mean with this.

torrent, from where, and how?

Thank you for replying timely.

What I meant by "torrenting old files" is that I use QBittorrent to download files into the SATA SSD that I use as an external hard drive. The files being corrupted means that when I disconnect the SSD and reconnect it, there's often a problem with the files. When I transfer files sequentially from another drive, after disconnecting and reconnecting the drive, the files are fine.

Like I said earlier, the SMART data of the SSD is fine.

Well unfortunately, Amazon doesn't have a commercial presence in my country. Which is why I turned to Aliexpress.
 
I would use a hex editor (eg HxD freeware) to compare a corrupted file with a good copy. That should help to visualise what is going on.

I expect that the USB-SATA bridge is the problem rather than the SSD itself. For example, some older JMicron bridges had a silent data corruption bug.

Your SMART report looks like a Silicon Motion SSD.

If you copy the Identify Device and SMART data to the clipboard (from CDI's menu), you could then paste it into your next post. This will identify the SSD's controller and NAND flash type.

BTW, CDI has a menu option which redacts the serial number from your reports.

I'm sorry to hear that
If there is any computer stores in your area, go there rather than Aliexpress
Hell, even Ebay would be a preferable option

Thank you for your timely reply. I think I would seriously consider that. Although I wonder if the right brand/stores might make a difference. I mean Western Digital, Lexar, HikVision have Global stores in Aliexpress. Wouldn't their products be authentic?
 
I wouldn't put a lot of trust in this:

Thank you very much for your timely response and help. I've updated the link in the first post. You suspect it's the bridge in the USB enclosure? The funny thing about that is that I got a USB enclosure from AliExpress, two in fact. One of the enclosures I inserted an old Seagate Hard disk drive. And in the other one, I inserted this SSD. What's interesting is that the issue only occurs with the SSD and not the HDD. It makes me wonder if the USB enclosure could entirely be the culprit here.

I would like to identify and isolate the cause of this behavior for future reference and learnings. I can't return either the drive or the enclosure. Here's the data you requested from the CDI;

Thank you for your timely response. Yes, I wouldn't put a lot of trust in it either. The drive was not purchased for critical use but as a download location for the files I was torrenting. The weird behavior is what I would like to isolate and understand the cause of.
Does this happen with any other drive in your system?

If not, the 'cause' is a $17 device from AliExpress.
 
Attribute 0xC5 suggests that the SSD is starting to degrade. The other attributes look suspicious, but it's hard to be sure because attribute values are not standardised.

I was hoping to find the name of the controller in the SMART dump, but I only found a date.

Your USB-SATA bridge IC is a JMicron, but I can't see whether it is a problematic one. You can open up the enclosure and examine the chip's markings.

Code:
-- Controller Map ----------------------------------------------------------
- Intel(R) 400 Series Chipset Family SATA AHCI Controller [ATA]
+ USB Attached SCSI (UAS) Mass Storage Device [SCSI]
- JMicron Generic SCSI Disk Device

Attribute 0xC5 suggests that the SSD is starting to degrade. The other attributes look suspicious, but it's hard to be sure because attribute values are not standardised.

Code:
-- S.M.A.R.T. --------------------------------------------------------------

A0 100 100 _50 000000010002 Uncorrectable sectors count when read/write

I was hoping to find the name of the controller in the SMART dump, but I only found a date.

Thank you for your timely reply. Could you tell me how you were able to interpret the SMART data? I would like to learn to do so as well.
If I understood you correctly you think the data corruption has to do with the USB cable?

Or the USB-SATA bridge? I went through that article - it seems to be discussing affected USB-SATA bridges? Luckily the drive enclosure is transparent, I can try to identify the bridge IC

Okay, I've got a JMS576B (2151) SATA R1.0 2022 07 18.

A nice person on Reddit wrote that "It could be the UASP compatible USB chipset that can't keep up when torrenting hammers the drive with I/O requests. I've seen this corrupting SATA SSDs in USB enclosures many times.
If it's actually an internal SSD in an enclosure, try connecting it to SATA directly and see if that helps."

Unfortunately, I can't connect the drive via a direct SATA connection.
It's looking more likely that the USB-SATA bridge might be the reason for the reason for the data corruption. Cause when I transfer files to the drive sequentially, I don't experience this problem.
