Audit ACL on Large File Share

Question

I have to audit the permissions of all folders on a large drive, and I was wondering if the following code is really practical with this many possible folders.
$ntfsreport = @()
$folders = Get-ChildItem \\serverA\F$ -recurse | where {$_.psIsContainer}
foreach ($folder in $folders){
$acls= (Get-ACL $folder.fullname).Access
foreach ($acl in $acls){
$arrshare = [PSCustomObject]@{"Path"=$folder.fullname;"Name"=$acl.identityReference;"Inherited"=$acl.IsInherited}
$ntfsreport += $arrshare
$ntfsreport
I am afraid of the memory hit building the $folders and $acls arrays, and not to mention the time it will take. I tried piping everyting down to Foreach-object so the processing can be ongoing, but I kept getting an error that Foreach-Object is not
a recognized cmdlet, function, etc. error. I couldn't figure out why so I went with the above code. 
Should I be concerned with memory performance and the runtime for $ntfsreport to finally be available?
TIA

Hi Shane,
Give this version a try:
$ntfsreport = @()
Get-ChildItem \\serverA\F$ -Recurse | Where { $_.PsIsContainer } | ForEach {
$folder = $_
$acls= (Get-ACL $_.fullname).Access
foreach ($acl in $acls) {
$arrshare = [PSCustomObject]@{"Path"=$folder.fullname;"Name"=$acl.identityReference;"Inherited"=$acl.IsInherited}
$ntfsreport += $arrshare
$ntfsreport
This one is using ForEach-Object for the outer loop.
