I bought a\u00a0Seagate Cheetah 600GB ST3600057SS SAS hard drive and it\u00a0has a problem with file transfers. I have tested it on three different PCs and three different SAS Controllers. Transfer rate with a Seagate Cheetah 15.7k and a WD VelociRaptor 600GB is initially fast, 80-100MB\/s, but later it slows down to 10MB\/s and stays there.<\/p>\n

I tested some more, and HD Tach seems\u00a0to\u00a0reproduce the issue.<\/p>\n

Read and random access is fine<\/p>\n

I got a new drive, and it has the same problem. I tested it in a different computer this time, and it was now detected by Seatools. I ran three tests, and they all passed.<\/p>\n

Short Drive Self Test (Short DST) – pass
\nGeneric short – Pass
\nGeneric Long – Pass<\/p>\n

 <\/p>\n

Success!<\/strong> \ud83d\ude00<\/p>\n

I switched for a Hitachi 15K600 Ultrastar 0B23663 HUS156060VLS600 and write performance is fine, both in Windows 7 and Windows 8.<\/p>\n

I have been in contact with Seagate tech support and here is what they said:<\/p>\n

– I apologize for any inconvenience this may have caused you. Unfortunately we do not have any tools that test the sequential write performance. Normally if there are issues with the drive , Seatools would fail the tests or give you an error code.<\/em><\/p>\n

This means that Seagate does not have any way of testing performance, and you are stuck with a problematic drive. <\/strong>Due to this, I won’t be buying Seagate products for a while. I was lucky that my retailer where I bought the drive accepted my returns and let me change to a Hitachi drive.<\/p>\n

I have also found other threads with the same issue with Seagate Cheetah drives:<\/p>\n
