Case1
$sql ="
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');
"
$Command.CommandText = $sql
Command.ExcuteNonQuery()

SQL profiler show CPU = 0 Duration 8 as result of bacth

Case2

$i =0
if($i -le 8) {
$sql ="INSERT INTO dbo.DbSecurity (Servername,DatabaseName,ContactUser) VALUES ('Server1','Db1,'User1');"
$Command.CommandText = $sql
$Command.ExcuteNonQuery()
$i++
}
SQL profiler show CPU = 0 Duration 1 -- for each execution

Question
Do we save on script execution time when submit batch of 500000 rows using call in (in case 1) looop 500000 times inserting row by row (Case2)?

I suggest looking into SqlBulkCopy with a DataTable.
