Welland ME-747ANS

The Welland ME-747ANS attaches one disk to your network but only at 100Mbps, not the standard Gigabit. For that reason alone I rejected it. When they have a Gigabit version, it might be worth a look.

You get a LAN cable, a USB cable, and an eSATA cable in the box. You also get a CD and, if the Welland is like all the other NAS boxes, you do not need the CD because you can allocate an IP address to the device using the DHCP in your router. You can then access everything through the Web.

Features

Some of the features are good.

  • File System: XFS
  • SAMBA and FTP file transferring protocol
  • eSATA Interface
  • USB Interface
  • USB Printer Server
  • Compliance with UPnP embedded devices
  • Firmware upgradable

Some of the features are meaningless because you do not install NAS for those features or worthless because there are better options.

  • iTunes Server
  • LAN Speed 10/100Mbps
  • File System: FAT32, NTFS Read Only
  • BitTorrent download

Uses

The network connection is too slow so do not use it as a NAS. If you have a slow network then you will have to upgrade your network to carry NAS traffic at a decent speed.

You might use it for slow speed backup. You could use it as a print server for a USB printer. You could then make a habit of copying documents to the device for later reprinting. If you product lots of material that is freely reprinted by other staff, they could find it on the NAS and easily send it to print. Just note that the data will go across the network twice, once from your NAS disk to your computer, then again from your computer to the printer. With modern disks and printers, both will flood a 100Mbps network.

When you mix 100Mbps devices with Gigabit devices on a Gigabit network and use some of the cheaper hubs, switches, and routers, you will slow down all network traffic.

Conclusion

Modern disks are faster than a 100Mbps network. Look for a NAS device with a Gigabit connection.

Comments

I have one of these drives, it is very slow, it does not even operate at full 100Mbps speed, more like 2MByte/s to 4MByte/s. I would want to test the gigabit version in a shop before buying that instead!

It's fine for automated backups (I use Syncback SE) but way too slow for copying movies etc back and forth.

Also for large files (eg 1.4GB) it seems to disconnect part way through, so I can't actually copy anything larger than about 800Mb onto it.

100 Megabit per second is 10 MegaBytes per second. On a busy Ethernet network with collisions, a 40 percent throughput is common. Your 4 MBytes/s would be normal on a busy network and not acceptable on a quiet network. Is your network busy? It is time to upgrade your network if the slow down is caused by the network.

Your 2 MB/s is too slow. A slow down can be caused by the Windows overhead of opening small files across the network. If you use Windows and you get 4 MB/s for large files then 2 MB/s for lots of tiny files, the speed difference is about right. On a quiet network, you should get 8 or 9 MB/s for large files and 6 or 5 MB/s for small files.

The disconnection can be network traffic timing out or poor software in the Welland device. My Qnap device jumped up by a remarkable amount after a firmware upgrade. Does the Welland offer firmware upgrades? Have you tried any? Manufacturers appear to be happy to ship a product with firmware that is not good enough to be called beta software and certainly not fit for retail sale.

Did you try the disk with a backup through the eSATA connection or the USB 2 connection? How do they compare?
