This is a genuine Silicon Power Ace A55 4TB SATA III solid-state drive (2.5-inch form factor). It was previously used in a Synology DS920+ NAS as part of a storage array and is being sold because the system was upgraded to higher capacity Seagate Ironwolf hard drives.

Health & Testing
The drive has been tested with CrystalDiskInfo and Hard Disk Sentinel. Overall health is good with no critical SMART warnings. Power-on hours and total data written are relatively low for a drive of this age and capacity. Screenshots of the SMART data are included in the photo gallery.
Serial Number Note:
The serial number printed on the drive label is the official one. CrystalDiskInfo and Hard Disk Sentinel may show a different internal serial number — this is normal for Silicon Power A55 SSDs and does not affect the drive. The SMART health screenshots included in this listing are from this exact drive.
What’s Included
- The SSD itself (no screws or mounting hardware)
Important Notes
- This is a used drive pulled from a working NAS. It is sold as tested and working.
- I recommend you perform your own health check upon receipt.
- No data is on the drive — it has been securely erased.
- Please review the SMART screenshots carefully before purchasing.
Returns:
I accept returns within 14 days if the drive does not match the description or arrives DOA. Buyer pays return shipping unless the item is not as described.
