Network Attached Storage (NAS) devices are a good solution for users who need a central place in the home network to their data and media to store and back up their family PCs. These days, most NAS devices, not extra duty as a media server and remote access when you are outside your home.
The only thing that most NAS devices have in common is that they typically have a streamlined version of the Linux operating system. Flying in the face of such scaled implementations, HP chooses instead to have its NAS devices running Microsoft Windows Home Server operating system. HP adds a good bit individually, and has the Windows Home Server provides storage, and the company it is all together in a package that contains a device with lots of space for storage capacity increases.

The two latest additions to HP NAS lineup, the HP MediaSmart Server EX490 and EX495. Both models are manufactured in a tiny (9.75×5.5×9.9 inch) glossy black plastic chassis. Other than price, are the only differences between the two models, the EX490 installed by a 2.2 GHz Celeron processor-powered and comes with a 1 TB drive, and the EX495 uses a 2.5 GHz Intel Pentium Dual- Core E5200 processor and comes with a 1.5 TB hard drive. Both units include 2 GB of internal memory. We had the chance to spend some time with the high-end EX495.
The EX495 features a mesh-front grill that swings out to reveal the way to four tool-less Serial ATA drives. The Bottom Bay is home to a 1.5 TB hard drive, while the remaining three bays lurked Hot-swap, the user-provided disks. The EX495 also has four USB 2.0 ports and one eSATA port, you can use external drives to further increase total storage capacity of the device or to back up the contents of the server. (HP notes that the EX495 is the maximum storage capacity of 17.5TB.) The chassis also includes a Gigabit Ethernet port and a security slot.

Most NAS devices are set up very simply, with little more than attaching them to the network by making them stand up to the needs and tweaking a few settings and go. Setting up the EX495, on the other hand, is an exercise in perseverance, patience and a little luck. As soon as the EX495 are connected to the network and powered on, it is not ready to go. First, you need a setup application from the included software installation CD. This first step does several things: It initializes the software on the server, but copies of the necessary software on the client PC, and it downloaded and installed on the server’s operating system and software. This process lasted over an hour and saw the server to go through numerous cycles restart.
We ran into a serious problem in our initial setup, which came in the server when downloading updates to a standstill. Fortunately we were able to log into the server and run the updates manually. However, we experienced a number of software crashes and a total of flakiness that we want to reset the factory defaults, forced, so we could start over. Reset the factory settings lasted over an hour, we had to wait before we could start the reinstall.

Once installation is complete, the Windows system, have to set up the server a few software components installed on it. One of the Windows Home Server Connector, which automatically configures a backup copy of the client PC to the server to connect to the Server folder share, is connected to the server and monitors the health and security of servers and computers. While folder shares are not automatically assigned a drive letter, a link to the server folder shares on the Windows desktop is placed. If you want to access photos, videos or photos with Windows Media Center, you must install the Windows Media Center Connector application.
HP recommends the HP Media Connector software on any Windows system you plan to install a connection to the server. Strictly speaking, this is not necessary because you should be able to server folder shares is installed without the software (as long as the server name or IP address known) access. If you do not install the software on a client but the client is not configured to be able to turn on the server or the server. There is also a Mac client to configure the Macs to the server and then allows the server through the Mac OS’s Time Machine utility.

Once all the software was properly installed on our client system, we have configured the server with the launch of Windows Home Server Console from the Windows Home Server icon in the taskbar. We have a number of users, so that we could access the server folder shares, then turned the integrated iTunes server, TwonkyMedia server and remote access. Of course we still need to get our media to the server gains the advantages of their media-serving functions, and the EX495 offers a unique and seamless way to do this. It contains a feature called Media Collector, that is, once configured on the server all connected Windows or Mac systems that the server software installed on them, can then automatically copy all your photos, videos and music files you are looking for notes up to the server. You can also manually copy your files to the server.
The EX495 also a unique feature, the video files to video files stored in H.264 converted. The purpose of the video converter feature is the optimization of video streaming devices such as a Microsoft Xbox 360, Sony PlayStation 3, or an Apple iPhone. You can create multiple profiles, so that the converter created different versions of your video files for different scenarios streaming. You can use variables such as screen size, video frame rate, video bit rate. The converter has two presets: “Full” for streaming from computers and game consoles, and “Mobile” for streaming to mobile devices. The converter recognizes popular file types (such as AVI, M4V, MOV, MP4, MPG and WMV) and video codecs (such as AVC, DivX, MPEG-1 or -2, and VC1). The converter also detects non-copy protected DVD files (VOB files and VIDEO_TS folder), but it does not work with ISO files.

We set up the EX495 to media from a Windows 7 system, a system with Windows Vista, and two different Macs running Mac OS X 10.6.2 collect, we also use the EX495 to all the videos about the standard profiles (full and convert Mobile). The EX495 chug away start, but an unfortunate side effect of this was that the device, the CPU utilization at 100 percent, which was slowed significantly coupled to the server. Even after collecting media from the different systems for a few days the media collector seemed to stop. We had the server database to reset the collection process back on track kick. If it is typical of our experience, it could take several days to get all your media on the server when a large media vault.
activated with the media server settings, you can stream media to a healthy collection of devices. The EX495 supports UPnP and DLNA, two standards for streaming media on many TVs and devices like the PlayStation 3 and Xbox 360 supports. If you enable remote access, you can also stream media to other systems and devices over the Internet. There is even a free iPhone/iPod touch app, HP MediaSmart Server iStream that allows you to access your media via Wi-Fi or 3G. If the EX495 remote access from another computer, it first takes you to the server of the HP home page, a host of options, including offering access to the media streamer utility, as well as folder shares. It also contains an applet that you upload photos from the server to a selection of popular photo-sharing websites.

While we appreciated the many things that could do the EX495, we ran into some additional problems. The first was that the HP MediaSmart Server software on our two Macs, a “validation error”. Reported We have seen that error, although, strangely, everything else seemed to work correctly, including the connection to the server folder shares, to access the server console and backup to the server via Time Machine. The next problem occurred, and that none of our systems can be produced on the server iTunes Server. We have also noticed occasional hiccups, we did not find the server console or the server console the settings of Windows could not load access. We found ourselves restart our client systems, and the server numerous times to solve these problems. (Sometimes a reboot worked, sometimes it is not.)
The Mac-Validation Error and the iTunes problems would not go away, but. At this point, if we did everything right, it meant the server reset to factory defaults again. Needless to say, we were less than happy about this, as the Collector and Media Video Converter is already accumulation of our media and our video conversion for several days. As the saying goes, though, is the third time a charm, and after reluctantly Starting Over again, most of the problems we encountered away, including the iTunes server problem. We ran into the occasional hiccup, though, and the Mac client still displaying “Validation Error”.

Some additional questions we have are with the EX495 that you do not have a static IP address. The server settings are under incoherent spread in different areas of the user interface. Other shortcomings: It can not be used as a print server, and it does not natively support FTP (although advanced users should be able to install FTP server software).
The last thing we did with the EX495 was to see how well they performed. Fortunately, after he had all the problems, we happy that the EX495 some of the fastest network speeds we’ve seen from a consumer NAS device had. With an HP Pavilion Elite m9550f Desktop PC (2.5 GHz Intel Core 2 Quad Q9300, 8GB DDR2, 1TB 7,200 rpm hard drive) Windows 7 Ultimate as our testbed system, we saw write speeds as high as 66.1MB per second ( 554.3Mbps) and read speeds of up to 45.6MB per second (382.2Mbps).

We also have a look at the device power consumption. When sitting idle (not all do file transfers or video media collection converts) swayed EX495 39-53 watts. Beat them with file transfers, streaming media, media collection and video conversion at one time, the EX495 uses around 62 watts.
The EX495 is very expensive for a NAS device. We welcome all EX495 features, especially those not normally found on NAS devices: the media and the Collector Video Converter. But even with all the expansion of space and its fast performance, we are not sure whether the EX495 it’s worth, what with all the headaches it gave us. Of course you can vary your performance and you could call us cynics, but we are always a little wary is adding additional equipment for our networks, Windows, when you consider all the updates and restarts connected therewith. These other NAS vendors are to do with the use of a streamlined Linux in their devices.
