on some architectures really improves performance.
/drivea is the mountpoint of one filesystem, /driveb is the other mountpoint.
This will NOT check file similarity, only existence of names and directories.

And large (in the sense of inodes (UNIX term for file name slots)) directory trees are inherently inefficient, and become prone to errors when free inodes become scarce. i.e., 'millions' of files on a single file system are usually a really terrible idea.
Windows filesystems are not immune to this problem.
Develop a means of archiving off fasta files or whatever your are using. Save last month's files on permanent storage - disk is NOT permanent. You just discovered that, I see.
Then remove them from the disk. Just keep recent data. I realize that research or medical testing means keeping data almost forever. Ask your legal guys how long 'almost forever' is. And maybe learn about off-site archival storage in the neighborhood. Having a defined retention policy is better than trying to keep everything. Less costly, too.

volcheck
volcheck(1) User Commands volcheck(1)NAME
volcheck - checks for media in a drive and by default checks all floppy media
SYNOPSIS
volcheck [-v] [-i secs] [-t secs] pathname
DESCRIPTION
The volcheck utility tells Volume Management to look at each dev/pathname in sequence and determine if new media has been inserted in the
drive.
The default action is to volcheck all checkable media managed by volume management.
OPTIONS
The following options are supported:
-i secs Set the frequency of device checking to secs seconds. The default is 2 seconds. The minimum frequency is 1 second.
-t secs Check the named device(s) for the next secs seconds. The maximum number of seconds allowed is 28800, which is 8 hours. The fre-
quency of checking is specified by -i. There is no default total time.
-v Verbose.
OPERANDS
The following operands are supported:
pathname The path name of a media device.
EXAMPLES
Example 1: A sample of the volcheck command.
The following example
example% volcheck -v /dev/diskette
/dev/diskette has media
asks Volume Management to examine the floppy drive for new media.
The following example
example% volcheck -i 2 -t 600 /dev/diskette1 &
asks Volume Management if there is a floppy in the floppy drive every 2 seconds for 600 seconds (10 minutes).
FILES
/dev/volctl Volume Management control port

Due to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive. Continu-
ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
of high use.
