Interface Bandwidth

LaCie says that the 4big Quadra reaches up to 230 MB/s throughput via eSATA. We selected a RAID 0 to check the throughput, but we could not see more than 175 MB/s. Although four 7,200 RPM drives can theoretically reach approximately 400 MB/s in an ideal RAID 0 environment, 175 MB/s is still a good result.

As you can see, the maximum throughput clearly depends on the interface. The 175 MB/s we mentioned can only be reached on eSATA. FireWire 800 reached 80 MB/s, which is one of the best results we’ve seen on this interface. 40 MB/s is typical for FireWire 400, as is 35 MB/s for USB 2.0.

Access Time

Access time depends on the RAID level you select: RAID 0 clearly is the fastest, providing a quick 13.9 ms average access across all four drives. RAID 5 takes as much as 18 ms for average access time, while a RAID 10 array or degraded RAID 5 array are slightly faster. These numbers, however, are only important if you intend to run applications off the 4big Quadra, which typically won’t be the case—this is a mass storage product.

Beware of this unit... There's a very nice article in German's CT Magazine that describes some 32-bit limitations and its consequences. Because of 2 TB limit it can overwrite the first sectors and corrupt all data on it just by connecting to a Windows PC alone.... Besides that, not all chipsets will work with this unit.

You said "..Here is one that stores up to 4 GB, is extremely stylish,..."
Do you really mean 4gb or was that a typo?

Keep reading. Further down it say 4TB.

this "stylish" LaCie is no match for the Qnap TS 639 Pro. If you care about safe storage why this Quadro does not support Raid 6?? If you want to keep important data safe, in my case it is 30 years of photography,
use server-drives like WD 1002FBYS which are a bit more expensive but also 24/7 drives and not those seagate barracudas. Also the Quadro is pretty slow. At least compared to the Qnaps. And also not more exoensive. Before I switched to Qnap I bought about 8 TB of LaCie drives. They worked but in case you need a good Raid-system think twice!
