New pro/con: No media player extensibility; which is especially odd when considering that this product is marketed toward *home* and small business. Should work fine with a Popcorn Hour media server nonetheless.
New pro/con: Most user forums agree that when a drive fails in RAID5, RAID5+, and/or RAID6 that the unit is able to seamlessly recover data and rebuild if a replacement drive is inserted.
New pro/con: No clear instructions on how you would go about upgrading hard drives to larger capacity units. No mention if volume expansion is supported.
New pro/con: No visible online 'hacking' community to develop and share applications or plugins to enhance this hardware. [as opposed to the very rich hack community with other NAS products such as the D-Link DNS-323]
New pro/con: Huge negative: no support for UPS connection via USB -- if the power fails, you NAS crashes. Not sure how anyone could have missed such a glaring oversight.
New pro/con: Has three eSATA posts and one USB expansion port for plugging in additional drives.
New pro/con: Customer service/support from LaCie is usually regarded as terrible.
New pro/con: can read from FAT, FAT32, NTFS, HFS+, EXT2, EXT3, REISERFS and XFS formatted drives. Unclear if it is REISERFS3 or REISERS4 that is supported. Unclear if EXT4 will be supported in the future.
New pro/con: CPU is a Marvell 88F5182 "Orion" processor (@ 500 MHz). a 900-1.1ghz processor would have been more suitable; 500mhz is easily bogged down when making parity calculations (RAID5 and RAID6) leading to this product sometimes crashing if it 'is driven too hard.'
New pro/con: supports 1.5tb and 2tb SATA drives
New pro/con: does not support the (extremely excellent for network storage) ZFS file system :(
New pro/con: insufficient ram: only 128mb ram with 4mb flash memory. way way low for for a product in this price category; especially with as cheap as ram is these days.
New pro/con: spare drives / drive trays are available, at an exorbitant price, and only as a drive/tray combo, not tray alone.
New pro/con: not available as a shell, you need to buy the unit with hard drives. The drives LaCie puts in here are definitely not what a knowledgeable person would use. (cheap hitachi's provided at premium cost)
New pro/con: extremely affordable raid6 product with 5 drive bays.
