How much does the first 15.36TB SSD cost for ordinary consumers, compared to a HDD of similar capacity

TeamGroup announces the newest SSD storage device in the QX range “Extra Large”, with a capacity of 15.36TB.

Based on the 2.5 ”format, the new SSD uses NAND flash chips with 3D QLC technology, created to deliver increased storage capacity at competitive prices, in exchange for a slightly lower endurance, compared to the storage solutions preferred by enterprise customers. Thus, the new 15.3TB TeamGroup QX model comes with an endurance estimated at 2560TB measured in data writing operations.


By all accounts, that endurance corresponds to the transfer of a volume of data representing 15% of the total storage capacity, each day, until the expiry of the 3-year warranty provided by the manufacturer. However, 2.95 TB recorded every day far exceeds the typical scenario of a PC user, even in the case of intensive use of video editing applications, or file downloads (eg BitTorrent). Rather, the transfer speeds limited by the SATA interface to 560 MB / s read operations and 480MB / s when writing data are the main obstacle, currently there are SSD storage solutions that offer transfer speeds of up to 7GB / s via PCIe 4.0 interface .

Introduced as a regular SSD with SATA interface, which can be installed in any PC or laptop with a 2.5 ”slot, the new 15.3TB TeamGroup QX model benefits from completely quiet operation, low power consumption, transfer speeds and access times clearly superior to any conventional hard drive. The downside: the official price of $ 3990 per unit and the availability is apparently exclusively for OEM integrators, which means you won’t find this product in stores.


For comparison, the top of the Seagate range on the top IronWolf range (designed for network storage applications with 24/7 availability, no limit on the volume of data transferred and a 3-year warranty) offers 16TB of storage capacity at the price of $ 509. Obviously, the disadvantages are multiple, starting with the transfer speeds halved and the access times with many orders of magnitude lower. But, for trivial data archiving tasks, choosing the SSD solution is almost impossible. For example, with a budget of $ 1010, representing a quarter of the cost of the SSD solution, you can simultaneously have storage capacity and redundancy in the face of possible hardware problems, purchasing two 16TB hard drives to build a RAID-type configuration. 1.
