I've been testing a Sun T1000 now for about the last three months. This was after I said goodbye to my T2000, with much sadness, back in May.

At first glance, the T1000 and T2000 look like the same basic construction, but with the T1000 supporting fewer internal drives. That's not completely true - the T1000 is only 1U high and to keep with the necessary cooling and the reduced height, some of the internal elements have been trimmed too. The less complicated internals should in theory be a bonus, because with less complicated components, and fewer numbers of them, there should be fewer things to go wrong, which in turn should have a real impact on the MTBF (Mean Time Between Failures). It's difficult over three months to say that categorically, but the theory is sound.
