Subject: Very slow i/o to external hard drive's HFS+
Date: Wed, 16 Sep 2020 11:16:38 -0400 [thread overview]
Message-ID: <78677a3e-7f0c-d9e0-8542-6ab44ae5fe75@cruzio.com> (raw)
Hello
I have a removable hard drive sporting an HFS+ connected to a USB3 port.
The drive is a Seagate Slim Line 2T.
I am using a driver from Paragon Sofware to write/read from this drive.
I am running Windows10 build 19041.508 (ie up to date)
Writing to this file system using the unix cp command is incredibly slow:
cp my_file /cygdrive/h/some_destination
The same write, using copy paste in Windows Explorer is much faster.
I have not precisely timed it, but it is way more than an order of magnitude
faster (a 1G file took approx 10 mins: the graphical display shows just
a few seconds).
(In Windows Device Manager I have the policy for the drive set to be
"Better Performance" and not "Quick Removal" -- apparently
the latter can lead to dramatic degradation in performance).
Can anyone suggest what might be the cause?
