Check a slow file copy before buying a new drive
A slow file copy can involve the source, destination or connection. Record the arrangement before replacing a drive.
Use non-sensitive test files and keep a backup of important data. For work or university equipment, follow the service desk’s instructions rather than changing managed settings.

Record the connection
Write down both devices, the cable and any hub or adapter. Note whether the delay affects one file or every transfer. A large collection of small files can behave differently from one large file, so compare like with like.
Check a simple permitted test
Try the same non-critical file through a manufacturer-supported direct connection where allowed. Keep the original intact and inspect the copy. Do not format a drive or remove its contents merely to test speed.
Read official support guidance
Check the exact drive and computer documentation for supported ports and cables. Avoid unrelated driver utilities. Microsoft’s recovery guidance explains why backups matter before disruptive recovery; recovery is not the first response to an unexplained slow copy.
Write a useful support note
Record the file size, elapsed observation and whether the test changed the result. Stop using a drive that shows errors or signs of failure and seek appropriate support. Buy hardware only when a supported specification or diagnosed fault identifies the need.
Make the next decision from your own setup
Before buying replacement equipment, keep a short record of the symptom, the supported test and its result. Avoid changing several things together or sharing private information to obtain an opinion. For managed equipment, give the record to the approved service desk. Ask which next action is authorised before performing recovery or making configuration changes. Use these checks when comparing a slow file copy before buying a new drive.
