WD vs LaCie NAS Specs
Storage Capacity
The Western Digital AV-GP offers 1TB of storage space. This single drive fits into standard 3.5-inch NAS enclosures. The LaCie 2big Triple provides 2TB of total capacity. It achieves this using two internal SATA drives in a RAID configuration. You get double the space with the LaCie unit. The Western Digital option is smaller but simpler. You must choose based on how much data you need to store. The LaCie drive scales higher for larger media libraries.
Rotational Speed
The Western Digital drive uses IntelliPower technology. This means the rotation speed varies between 5400RPM and 7200RPM. It adjusts based on workload to save power. The LaCie product data does not list specific RPM values. It relies on two internal drives for performance. The Western Digital speed is flexible for surveillance and NAS use. You get a defined range with the WD drive. The LaCie specs focus on interface speed rather than motor speed. You cannot compare exact RPMs directly from the provided data.
Cache Size
The Western Digital AV-GP includes 64MB of cache memory. This buffer helps manage data flow between the drive and your NAS. The LaCie 2big Triple specifications do not list cache size for its internal drives. You get a known 64MB buffer with the Western Digital unit. This helps with write performance in standard NAS setups. The LaCie drives likely have cache, but the data is missing. You rely on the Western Digital spec for this metric. The LaCie advantage lies in its RAID hardware instead.
Hardware Interface
The Western Digital drive uses SATA III 6.0Gb/s. This is the standard interface for most NAS enclosures. The LaCie unit offers FireWire 800, FireWire 400, and USB 2.0. These are external connection types, not internal NAS interfaces. The Western Digital drive connects directly to your NAS motherboard. The LaCie drive connects to your computer via external cables. You need a compatible NAS for the WD drive. The LaCie unit is a standalone external storage solution.
Form Factor
The Western Digital drive is a standard 3.5-inch internal hard drive. It fits into internal drive bays in NAS systems. The LaCie 2big Triple is a complete external enclosure. It measures 7.8 inches in length and 6.7 inches in width. You place the LaCie unit on a desk or shelf. The Western Digital drive requires a NAS chassis. You get a compact internal component with Western Digital. The LaCie unit is a larger, self-contained desktop device.
