NAS Failure:

NAS boxes are now popular storage solution options for businesses and home users alike. NAS devices are however prone to failure due to their continual use (i.e they are left on 24x7), also misuse and poor technical support. Our experienced Techs have ALL failure situations covered and are on hand to restore your data and system.

Computer Science Labs is "THE" industry leader when it comes to Emergency Data Recovery and Emergency System Restoration from failed Business and Home User Network Attached Storage Devices (NAS Boxes) with inaccessible or faulty hard disk drives and hardware"

There are many manufacturers and models of NAS boxes, Listed below are a few current models that Computer Science Labs have repaired and recovered data from;

Apple Time Capsule, Buffalo Linkstation, Buffalo Terastation, D-Link 4-Bay Network Storage Enclosure, HP MediaSmart Server, Infrant Ready NAS, Iomega NAS 100d, Iomega Storcenter Pro, Iomega Storcenter, Lacie Ethernet Disk, Lacie Ethernet Disk Mini, Linksys Etherfast, Linksys, Linksys by Cisco, Maxtor Central Axis, Maxtor Shared Storage Drive, Micronet Raidbank, Netgear Ready, NAS NV, Netgear Ready NAS, Netgear Ready NAS NV+, Netgear Ready NAS Duo, Sans Digital Mobile NAS, Seagate Blackarmor, Simpletech Simpleshare, Synology, Thecus, Vox Blackbox, Western Digital Sharespace.

NAS Operating System:

Most NAS units are used with Windows or Mac OS systems, however most users are unaware that beneath the available interface is a Linux based operating system that manages the network file sharing and other services required by the NAS unit. Computer Science Labs Technicians are fully Linux, Microsoft and MAC proficient.

NAS Technology:

On the market today there are a variety of digital storage devices and options available to consumers, There are remote storage options such as “Cloud Storage” services, “Dropbox” which, for a relatively small monthly fee you can use to back-up and store your data in a fluffy “Cloud” of storage devices.

DAS (Direct-Attached Storage) devices such as USB external hard disk drives are primarily designed to expand the storage capacity of standard computers whilst providing flexibility in sharing and the mobility of your data. Businesses have more complex storage needs that in the majority of cases are best satisfied by Server Systems with RAID configured hard disk drives and SANs (Storage Area Networks).

NAS however is an important component in the chain of a burgeoning need to securely and efficiently store your data. NAS provide more features and capacity than DAS devices, and unlike most DAS devices, data stored on a NAS device can be shared with others on a local network or over an internet connexion.

NAS devices are inherently less complex than business class storage set-ups such as SANs.

NAS solutions can range from single fixed-drive enclosures, such the Iomega Home Hub, cloud Edition to an Small to Medium Business system that can be configured with RAID and fault tolerance. The Buffalo Tera Station Pro is a good example of a business-class NAS.

Data can be shared by connecting a NAS to a network but many vendors are increasingly offering a bundled cloud service as a way to invite others to share data on your NAS.

Cloud Based NAS devices, like the Pogoplug series 4, target home and SOHO-business users. Business-class NAS may have a cloud service you can access to share data, but, more often than not, sharing via the cloud is not a highlighted feature. With business NAS, data sharing usually is confined within a network, or through remote access via configuring and securing ports and setting up port forwarding.

Current NAS, whether for home users or small business, can do so much more than store data. Most NAS devices can function as media, FTP, iTunes, or even sometimes database and email servers.

Many NAS devices for home users can integrate with social media and content sites like Facebook and YouTube. Some NAS devices can be used as low-cost video surveillance solutions because they integrate with IP cameras.

Why use NAS?:

A network attached storage (NAS) device is primarily a centralized repository for data. It differs from a direct-attached storage (DAS) device in that instead of attaching directly to a computer, it attaches to a network. A NAS is used largely for files haring, and these days, for streaming multimedia. Yet many NAS boxes are also servers, because they almost have an embedded Operating System (usually Linux), and are networkable usually via an Ethernet port, although some are now featuring wireless connectivity—so they can store data for all the computers on your network. The storage space can be comprised of USB or hard disk drives. The NAS market is competitive. There's a vast array of NAS devices to choose from. What you choose depends on what you need. Some NAS devices only support USB storage; they're usually much smaller than the ones that hold standard SATA hard disk drives—and a lot cheaper. Some NAS has extensive software features that allow you to do specific tasks, such as hosting a Web server on them. Others allow remote access. And, of course, there's the amount of storage offered, and whether the box offers RAID functionality or not

Here are some key aspects of NAS devices to consider when making a buying decision,

NAS Capacity:

The main purpose of NAS is to provide centralized, shared storage, A number of Hard Disks being connected within a NAS enclosure. Usually affordable consumer class drives, four is usual, making up a total larger capacity operating in a RAID configuration. The Iomega iConnect Wireless Data Station effortlessly handles several TBs of storage. That's a lot of storage space for the typical home or small business user. What NAS devices tend to lack are disk redundancy options.

Wired or Wireless:

Most NAS devices out on the market now have wired Gigabit Ethernet connectivity. Many business-class offerings have two Gigabit ports for Port Trunking—which provides connection redundancy if one port fails. Port trunking also combines the link speeds of the two ports, thereby increasing network access speed. You can connect these NAS devices via Ethernet cable to a wireless router or a switch on the network. Most of them already have DHCP enabled and will pick up an IP address from the network (usually assigned by a wireless router in a home network.) If you plan on getting a NAS device that you want to remotely access and manage, best practice is to give it a static IP address for managing it locally on your network.

Vendors are offering wireless-N adapters for connecting wirelessly to a home network. QNAP for instance, offers a USB Wi-Fi dongle for its TS-21x family of NAS. The issue with a NAS connected wirelessly via 802.11g or 802.11n is that you are not taking advantage of the Gigabit speed that having a NAS with a Gigabit Ethernet port wired to a router can offer. Unless you are planning to stream video or perform large file copy uploads and downloads, you might not want to pay the price of added wireless support—better to spend any available money on storage and wired throughput.

Measuring Performance:



Like PCs, NAS units have memory and processors. With better processors and increased memory, you get better performance from a NAS, just as with PCs. Also as with PCs, the better the processor and the more installed memory, the higher the price. One of the fastest performing NASs the QNAP TS-259 Pro-2 Drive Turbo NAS Server owes its superior performance to its Dual Core Atom D510 processor. If you know your NAS will be handling a lot of I/O operations (such as users saving and retrieving data from it on a regular basis) it pays to go with a NAS that has a nimble processor and maximum memory. Most of the SMB NAS are shipping with the Atom processor while the more inexpensive devices for home use often ship with a Marvell chip.

NAS Operating System:



Is your home or business network Mac or Windows? Perhaps it's a mixture of both, maybe with some Linux clients thrown in. NAS for the home and SMB mainly support Mac and Windows environments, since that's where the market is. Many of the NAS devices that support Mac file systems also support integration with Apple Time Machine. This also gives a well-rounded backup solution.

NAS Back-Up and Recovery:



The data you store is only as good as your last restored backup. Higher-end NAS products often have sophisticated management options to configure RAID, or some sort of built-in monitoring system that will alert about impending drive failure and other problems. If your data is mission-critical, these features are essential, One of the best NAS for recovering from a failed hard disk drive is a DroboPro FS.

Another important consideration with NAS disaster recovery: hot-swappable drives. Many newer HDD-based drives will allow you to "hot-swap" out a dying disk drive with a new drive without having to power the NAS down or with little or no interruption in productivity. Many NAS devices with this capability are aimed more at businesses.

The NetGear ReadyNAS Duo is an example of a hot-swappable NAS. Some NAS vendors are bundling cloud as a back-up platform for a local, physical NAS. The data on the NAS is mirrored to a server in the cloud. This is often known as a "hybrid" backup solution, and it gives the best of both worlds, as data is stored in two disparate locations. This is ideal for information that you absolutely cannot afford to lose.

Having data reside in the cloud also provides a way to perform a restore in the event of disk failure in the local hardware. The Egnyte Hybrid Cloud Solution is a good way to add cloud functionality to any NAS. NAS devices can also backup their own settings and configurations. This is important especially in a business settings that may have very specific configurations specified.

NAS Noise:


Like any other type of server, NAS can be noisy. The noisy ones are the ones that hold hard disk drives, especially when the enclosure supports 4 or more drives. If you are placing the NAS in a server room—and some of them are rack-mountable—that's not a problem. In your home or in a small business office that's another issue altogether. One of the quietest NAS solutions is Iomega's Storcenter ix4-200D for business. For consumers, LG's Super Multi N2A2 is suitably quiet.

NAS Energy Efficiency:


Several NAS devices are designed to save on power, shut down and re-start according to a pre-set schedule that a user defines within the management software. This capability feature is called "Lights Out" in the Lenovo IdeaCentre D400 Home Server. Many business-class NAS have system monitoring tools that will report on the system's temperature and CPU voltage. QNAP's TS-212 have "smart" fan features which cool the hard disk drives down automatically to prevent overheating. Some business-class NAS also have system monitoring tools that will report on the system's temperature and CPU voltage.

NAS Remote Access:


NAS devices are shipping with remote access capabilities typically using cloud service to manage access and the data on it. Cloud services are also useful for sharing content with friends and family. Collaborating via the cloud is a big selling point. Buffalo are using cloud services like Pogoplug and customizing them for their devices.

NAS Software and Services:


Although much of the software that ships with NAS is focused on managing the device and streaming multimedia there are vendors providing a lot of extras. Some devices have built in WebServers, BitTorrent clients, iTunes server and even offer Telnet. Some can do extras such as a MySQL or FTP server. A lot of this functionality is included with the Seagate BlackArmor NAS 220. Many can not only stream multimedia, but can work with IP-based surveillance cameras. These kinds of advanced features are usually found in NAS for business, but lower-end options are sometimes bundled with sophisticated applications. You can always opt for a no-frills NAS, but if your needs warrant it, you can choose one that can act as much more than a storage server.

NAS Security:


Security is always a concern, whether it's for home hardware or business networks and many of the NAS devices support file encryption. Others also offer a variety of security controls to protect the NAS from intruders with firewall access protection. For example, business NAS devices often have physical security, like locked enclosures or Kensington Security Locks, or K-Slots, which tether the NAS to a wall or desk. The QNAP TS-259 is one example of a NAS that has K-Slots on its chassis. All NAS boxes have some level of user account and authentication method requiring a username and password to access the device.
