About this deal

Cloud functionality, which allows individuals and businesses to operate a personal cloud. Essentially your very own cloud storage solution.

LaCie is a company popular for it’s Thunderbolt storage. No other company has offered as many different models with this technology. The LaCie 5Big comes with a traditional pedestal form factor that can fit nicely under a desk. This hard drive uses Marvell hardware RAID technology, and you can align the disks in RAID 0, 1, 5, 6, 10 arrays or go for a simple JBOD configuration. Moreover, users can also configure more than one array in the system. Hard disk drives are cheap and offer plenty of capacity but they are bound to disappear in a not-so-distant future. Right now, the biggest portable hard disk drive has a capacity of 5TB; it uses a special drive that is slightly bigger than a standard laptop HDD which has a width of 2.5-inch and a height of 7mm.

Thunderbolt 3 technology was introduced a year ago, but still, there are many users of Thunderbolt 2. This technology wiped out Fibre Channel DAS and offered professionals a new way to access high-speed and high-capacity storage. Thunderbolt offers superior features to USB connectivity which isn’t expensive as 10 GB Ethernet. This connectivity was first introduced on a limited number of PC motherboards designed for audio and video professionals. Still, over time, the high-bandwidth technology made it’s way to other motherboards as well. A small plastic tool is included for you to pop the top of the unit off and access the drives inside for replacement. The drives are mounted on tool-less trays that slide out easily. Connecting external drives to this unit and managing different settings on this drive is very easy, and you won’t face any issues while setting it up or operating. This drive is available in a different storage configuration, and it is available in 4 TB, 6 TB, 8 TB, 12 TB, 16 TB, and 20 TB storage capacities. This hard drive offers flexible connectivity with ports available for FireWire 800, USB 3.0, and eSATA. This unit offers two FireWire 800 ports for flexibility through Daisy Chain. It is compatible with Windows and Mac and comes with a 2-year warranty.

Most such multi-bay devices are sold without the actual hard drives included, so you can install any drive you want (usually, 3.5-inch drives, but some support laptop-style 2.5-inchers). Their total storage capacities are limited only by their number of available bays and the capacities of the drives you put in them. The storage industry refers to these (as well as smaller-capacity externals as a whole) as DAS—for "direct attached storage"—to distinguish them from NAS, or network attached storage, many of which are also multi-bay devices that can take two or more drives that you supply. (See our separate roundup of the best NAS drives.)Solidigm and its two 30.72TB SSDs: The D5-P5430 (coming later this year) and the D5- P5316 , as well as the 61TB D5-P5336

But with square corners and an antiquated, two-tone design, the drive isn’t a looker. And it finished near the bottom of all of our performance tests. The two biggest hard disk drive vendors have released 22TB hard drives with Western Digital unveiling a 26TB model in 2022 (although you won't be able to buy it as it is a data center only product). Toshiba has a 20TB CMR Hard disk drive but no plans for a 22TB one yet. Striping is the default configuration. If you’d prefer a mirroring, it would be best to configure that using the provided software tools before loading any data – because any changes to the drive layout will delete all the data on there during the configuration process. Of these, the WD Drive utilities are the most vital, as they allow you to change the RAID configuration of the Duo.Hard drives may get you more capacity for your dollar by far, but first you need to consider a major difference in external storage these days: the hard drive versus the SSD.
