Netgear ReadyNAS Ultra - What is the difference between a 4 Ultra and Ultra 6 Home NAS device?

It is tempting to think that the only difference between a href = "http://networkstoragetips.com/netgear-readynas-ultra-4-review/"> Netgear ReadyNAS 4 Ultra and Ultra 6 home ReadyNAS NAS device is that one unit houses up to four hard drives for the RAID and the other will allow you to install up to six hard drives.

This is not the only difference, however, as there are a couple of other important distinctions between these two excellent selections for a storage system home network.

The first is the CPU, which will affect the performance of network storage device. The Netgear ReadyNAS Ultra 4 is equipped with an Intel Atom single core 1.66Ghz. Ultra ReadyNAS 6 on the other hand, has a more powerful dual core 1.66Ghz Atom processor.

Although most users will not notice the difference in these processors, keep in mind that these devices can last several years and are a versatile platform that can be expanded via Netgear has approved additional services. And with the high demands of high definition video, more users accessing the home at the same time put a load on SIN SIN may become visible over time.

The second is the addition of RAID 6 with double redundancy that is only available on the ReadyNAS Ultra 6 and not the Ultra 4. Although RAID6 requires a minimum of four hard drives and could theoretically done on the Ultra 4, Netgear has chosen to reserve this feature for only six disk capacity and network storage units in over their product.

If you are unfamiliar with the concept and RAID6 dual redundancy, perhaps you've heard the term RAID hot spare "before.

In other words, RAID1 or RAID5 will protect your data if one hard drive fails. With a hot spare in place, the device SIN immediately start rebuilding the failed disk information on the new array element that was once the hot spare.

Unfortunately, leaving your data vulnerable to a second disk failure during the time of reconstruction. Although not very likely, a second failure is possible. Because hard drives are so big today, this time of reconstruction can be quite long, especially if the NAS continues to provide resources to users who are reading and writing data during reconstruction.

With RAID6, the concept of emergency is the same except that data are continually updated so that if one drive fails, you're still left with a RAID array that is capable of supporting a failure additional hard drive without losing data - and zero time to rebuild!

In the case of a home NAS device, RAID6 can not be an essential feature in your purchasing decision. But since the ReadyNAS Ultra Ultra 4 and 6 are considered in the "prosumer" class NAS device and are very capable, they will often be found in professional situations where data protection is absolutely essential.

The third difference between the two ReadyNAS units is simply the size. Both are compact units, so in order to accommodate two additional units, it is necessary for the Ultra 6 to be slightly larger than the Ultra 4.
