Final thoughts, HEXUS.right2reply and HEXUS.where2buy

It's always a good idea to start the final page on a positive note, so let's go over what we like about the Two Big.

First up, it's pretty rugged. More so than the all plastic N2050, giving it a distinct advantage in this respect. Further, you can leave that screwdriver in the drawer... you won't need one to install a disk into the TwoBig. Setting up a RAID mode is simple, but cannot be done accidentally. Data rates in RAID-0 are pretty good and they're also good in RAID-1, both capable of handling random access rather well. It's sounding good for the TwoBig, isn't it?

Now, for the bits we didn't like. The cooling solution could be a little better. The entire unit gets pretty warm and while we don't think it puts the hard disks within in any immediate danger, it's not likely to help their life span. Unlike the N2050, Two Big has no USB connectivity, but seeing as it comes bundled with an eSATA card, we don't see the problem there.

We're not too keen on LaCie's warranty policy either. LaCie's manual for the Two Big advises that drives only be replaced by those available from LaCie. The manual then goes on to warn that the warranty may be void if this isn't followed and the device fails. We doubt LaCie would actually pull anyone up on this, but the wording of the manual does still give us cause for concern.

Finally, burst rates don't seem to be quite what SATA 3Gbps should be capable of, and the difference between PCIc and PCIe is negligible. If the PCIe card has little advantage over PCIc, then what benefit will be seen when the PCI-X card we had is plugged into a full PCI-X compatible slot? We guess if you are planning on hooking up a second eSATA device then it might be useful, but we can't see how a single Two Big would benefit from it.

Our reservations considered, Two Big is still a product that performs competitively and is built well. If we were going to buy one we'd buy the PCIe version. It's cheaper and as we've already stated, the interface used by the eSATA card doesn't seem to make much difference to its performance. TwoBig is listed at £599 inc. VAT on LaCie's site, which we think is a bit too expensive. A bit of Froogling doesn't show up any UK retailers for Two Big. If any do appear, we'd like to see the price at or below £500 when equipped with a pair of 500GB drives. That way it'll square up against the Thecus N2050, and we reckon that'll make Two Big the more favourable product.

HEXUS.certifications

Two Big performs well and is built well, so it passes the HEXUS.labs testing.

HEXUS Awards

As an external storage device, it's very nippy, just as nippy as the N2050. So, we're giving the Two Big 1TB a HEXUS.award for speed.

Why not test the Big mode where it is safer than RAID0 and have more space than RAID1? That will show how the controller (inside the enclosure) affect the performance.

And the NV RAID0 and LSI Megaraid results seem too low to me. Especially the IOMeter sustained write. Even my friend's old 3Ware 7500-8 (4x200G IDE RAID5) managed 37MB/s write. (I missed that LSI Megaraid review apparently). NV RAID0 barely faster than a single 750G disk is definitely wrong, my 4x300 on NF4 (raided in windows) gets 200MB/s easy.

For eSATA+RAID0 not even as fast as single disk I wouldn't give it a “Speed” award.
It squares up to the N2050 and in comparison to USB 2.0 is a lot quicker, which is what in our opinion warrants the award.

I don't agree that big mode is any safer than RAID-0 really. If a drive fails you're still losing data; all of it if you're unlucky… so only slightly safer.

NVRAID 0 isn't with two 750GB disks it's with 2x 250GB disks. Seems the pependicularly arranged 750GB can read mighty fast.

Hope that clears a few things up.
