JBOD. Just Bunch Of Disks. The SOHOTANK Series focuses on the applications of JBOD. Although not equipped with data redundancy, the JBOD function, however, provides the flexibility of data exchangeability with not RAID limitations. With our removable hard drive design, you can simply remove a drive and have it be used on another PC with ease. Help you to manage your digital libraries. With the digital snapshots or videos taken, the MP3s or MPEGs that you have downloaded, you can easily manage them by dividing them up to be saved in different hard drives. With the SOHOTANK systems available from 2 and 4 drive bays, having each drive store different types of files would efficiently help you in organizing your libraries for music, videos, photos, etc. Hard drives instead of CDs for archiving.

Maybe you are fed up with burning data to a CD to backup your data. Large files mean multiple CD burning at one CD at a time speed. It’s time consuming and inefficient. With the SOHOTANK Series, you’ll have ample space for storage for gigabytes and gigabytes of data instead of megabytes. Once a drive is full, simply remove the hard drive with ease, archive it then replace with a new drive. It’s a thousand times more efficient Great for video editing (Firewire model only) With many videos now requiring high resolution formats, this would mean high speed storage in order to meet the requirements of video editing. Through the SOHOTANK’s firewire 800 model, you can set it up to run at RAID 0 where you would be storing divided pieces of data into two drives simultaneously instead of one to increase the over all read/write performance. It's simpler with just a cord. Because the power supply is internally built, so all you need is a standard power cord that's commonly used among PC's.With external"brick type"of power supplies, if lost, it's unlikely to be replaced by other brands. With the standard power cord, if lost, they can easily be purchased and obtained anywhere without having to worry about voltage     ST3620 Series Model No. ST3620-2S-S2 Host Interface eSATA(300 MB/Sec) Drive Interface 3.5” SATA I 1.5GHz / SATA II 3.0GHz Hard Drive 2     Microprocessor None Support Mode JBOD Support Hot-Swap 2 Hot-Swap drive trays Cooling Fan 4cm Ball Bearing Fan     Power Supply 100-240V, 70 Watts     Dimension 122 (W) x 203 (L) x 102 (H) mm     Weight 1.67 Kg     Case Material Aluminum Case     O.S.
