Tips mem-Format Flashdisk dengan File system NTFS

Format NTFS

Sebagian kita mungkin jarang memperhatikan tipe file sistem yang digunakan Flashdisk kita, apakah itu NTFS, FAT32 atau FAT. Untuk mengetahui file sistem yang digunakan, klik kanan Flashdisk di Windows Explorer dan pilih Properties. Di sana terlihat tipe File System yang digunakan.

Tetapi ketika kita akan mencoba mem-format melalui windows Explorer, mungkin disana tidak ada menu NTFS, adanya hanya FAT32 dan FAT. Bagaimana cara mem-format NTFS dan apa bedanya dengan FAT32 dan juga FAT ?

Mengapa NTFS ?

NTFS merupakan format file system Windows terbaru setelah FAT32, dan mempunyai beberapa kelebihan seperti kemampuan menyimpan tambahan informasi mengenai file/folder (metadata), fitur keamanan, kompresi data, struktur yang lebih baik dan lainnya.

Selain itu, tipe NTFS bisa digunakan untuk mem-format ukuran yang lebih besar, Untuk FAT hanya 2 GB, FAT32 8 TB ( 8.000 GB), sedangkan NTFS bisa sampai 16 EB ( 16 juta TB ). Meskipun demikian, tetap saja NTFS ada kekurangannya, seperti tidak terbaca di Win9x dan proses baca tulis ke disk yang lebih sering.

Karena tiap file/folder menyimpan informasi yang lebih banyak (metadata), maka proses baca tulis tiap file/folder akan lebih sering daripada tipe FAT32 atau FAT, sehingga untuk flashdisk, mempengaruhi umur (daya tahan). Mengingat Memory Flashdisk mempunyai batasan baca tulis. ( artikel tentang menjaga flashdisk agar lebih awet bisa dibaca disini : Karakteristik dan Tips menjaga Flashdisk lebih awet )

Mengaktifkan format NTFS di Windows Explorer

Bisa saja kita mem-format USB Flashdisk dengan tipe NTFS dengan bantuan HP USB Format Tools. Tetapi sebenarnya Windows Explorer bisa melakukannya. Untuk mengaktifkannya bisa diikuti langkah berikut

  1. Buka System Properties dengan cara Klik kanan My Computer > Properties (atau dengan tombol Keyboard Win + Break )
  2. Buka tab Hardware kemudian klik tombol Device Manager
  3. Pilih Disk Drive dan pilih Flashdisk yang ingin di format dengan NTFS, klik kanan, pilih Properties.
  4. Setelah terbuka pilih Tab Policies
  5. Pilih Optimize for performance dan klik OK
    usb-device-properties
  6. Setelah itu coba klik kanan Drive flashdisk di windows Explorer dan pilih menu Format, maka disana seharusnya sudah muncul File System NTFS.

Yang perlu diperhatikan adalah ketika opsi ini diaktifkan, setiap mencabut flashdisk harus selalu melalui Safety Remove Hardware. Jika pilihan adalah “Optimize for quick removal” maka sebenarnya flashdisk bisa langsung dilepas, tanpa Safety Remove hardware

Test antara NTFS, FAT32 dan FAT

Saya telah mencoba beberapa perbandingan (terutama proses meng-copy data) dengan tipe yang berbeda-beda, dan hasilnya sebagai berikut :

  • Copy 11 file (ukuran masing-masing sekitar 170 MB) total sekitar 1.8 GB
    NTFS 04:44 ( 4 menit 46 detik )
    FAT32 05:09 ( 5 menit 9 detik)
    FAT 04:46 ( 4 menit 46 detik)
  • Copy 1.297 files (ukuran antara 1 KB sampai 23 KB) dengan total 8,23 MB
    NTFS 29 detik
    FAT32 56 detik
    FAT 58 detik
  • Kapasitas setelah di Format
    NTFS 2.038.044.672 bytes Used space 12.937.216 bytes (12.3 MB)
    FAT32 2.046.959.616 bytes Used space 4.096 bytes (4.00 KB)
    FAT 2.050.686.976 bytes Used Space 0 bytes

Terlihat proses copy data dengan NTFS, relatif lebih cepat, tetapi ukuran setelah di format sedikit lebih kecil karena memang diperlukan space tambahan yang lebih besar untuk informasi file/folder (metadata). Jika flashdisk sering digunakan untuk proses baca tulis dan tidak begitu memerlukan fitur-fitur NTFS, seperti keamanan data, maka memilih tipe FAT32 mungkin akan lebih baik.

Artikel berikutnya insyaAllah akan membahas tentang memanfaatkan tipe NTFS untuk melindungi Flahsdisk dari Virus yang akan membuat, menghapus atau memodifikasi Autorun.inf dengan program sederhana yang saya buat “Super Autorun”.
