The 2000 class family consist of 2 type, 2000 v1 and v2, and the 2200. The 2000 has OS in firmware, where the OS is stored on the HD on the 2200's. These are very quite units. The 2000 were not design for the higher heat loads of 7200 rpm hd, so a fan upgrade is recommended. These 7200 HD's also tax the power supplies more, mainly on startup. These were design for enterprise class work (24/7), so they had to be reliable. These are very reliable machines but now are very old units, 10+ yrs. As with any hardware age does play an important part. The only neg on these older units is that the drives can not be moved to any other platform to read. And the read/write speed is very slow. So if your units fail you will need to put your HD's in the same hardware with same OS if in firmware. Or have a recovery service read them for you. I have a 2200 that has been running 24/7 for 4+ years, no problem what so ever. Being 2 HD units you only have Raid 1, mirroring for data redundancy. It takes a min of 3 hds for RAID5. Now the SnapOS does not support any OS past XP so Vista or Win7 are out.

If you want newer and better hardware you need to move up to Guardian OS units. Most of these have gige ports, with OS on HD. You must have a working unit to install the OS to get one running. So do not buy one unless it is complete with sleds and is bootable with supplied HD's. I like the 4500's units but these are noisy due to blowers but performance is really good. But again your looking a enterprise class equipment and reliability.
