Buffalo TeraStation Pro 6 TB NAS in the works

Buffalo is preparing a new NAS system, the 6 TB TeraStation Pro. The system has four drive bays, with four pre-installed 1.5 TB hard drives. These drives can be configured in RAID 0, 1, 5 and 10 modes. An LCD displays the system's activity. It has one gigabit ethernet interface and two USB 2.0 ports The unit measures measures 170 (W) x 235 (H) x 310 (D) mm. Buffalo will start shipping this unit later this month and ask an estimated US$2080 for it.

Hmmm, interesting that it has 1.5TB drives.


Pity no E-sata, with 4x drives in RAID 0, gigabit will be the speed bottleneck.

eSATA and NAS don't go together. N is for NETWORK. Unlike your external storage cage.
Also, why would you want to quadruple data loss with RAID0?


Doesn't Datarobotics already have a 6TB NAS?

well, giga and E-sata would make a nice combination :)

On a PC with the same 4 drives in RAID 0, the array would offer an average transfer rate of ~330 MB/s. Imagine if the NAS is made to do that, and with a single 1 Gbps line, it won't give you any advantage of a 4 drive RAID 0. The max a 1 Gbps line can give you, is 128 MB/s. Bummer.

So there's no reason for you to set up a RAID 0, it will (mathematically) increase risk of data loss, while not giving you the performance gain expected.

well hey, they include USB 2.0. you think gigas bad, consider the speeds off that

Speed wouldn't be the only reason to RAID0. Not losing any storage space, and having a single large volume would be a benefit.

Why is that interesting? They've been available for quite a while now. Funny thing is that they increased in price over the last week though. Was planning on buying a few, though not when they increase in price like they do atm. Thinking of just buying a few TB drives for my new server instead.
eSATA is available on several NAS devices, I fail to see the point of it though, unless they offer a nice case with multiplexer. Only then would it have value over USB. Of course it should support multiple arrays that way, ie separate array for the cage.

Losing storage space or losing data... hmmm. Seriously, if you make a storage system you don't want it to be unreliable. Speed is the only reason for RAID 0, if you want 100% drive usage use separate volumes.

Isn't size of individual drives abstract anyway?

Hey, I never said is was practical. Just that it could be another reason to use RAID0.
