The first hard drives with a capacity of 30 TB are available from German dealers. Seagate offers it in two variants: once as Exos M 30TB (from € 586.89) and once as Ironwolf Pro 30TB (from € 623). Both variants rely on the same technology and are only marketed differently.
The Exos M is primarily intended for servers and the Ironwolf Pro for network memory (NAS). Both models can also install those interested in desktop PC. And at the latest with manufacturer certification, nothing speaks against a server variant in a NAS. The Ironwolf Pro only contains a data rescue service for three years, which justifies the slightly higher price. We have recently tested both hard drives.
Price per tbyte remains within the framework
The price is particularly gratifying in the case of exos M 30TB. Although it uses modern Heat Assisted Magnetic Recording (HamR), Seagate does not require an exorbitant surcharge. The estimated 590 euros corresponds to almost 20 euros per TB capacity. The Ironwolf Pro costs a good 21 euros per TB.
For comparison: that Best price-performance ratio of euros per TB currently offer hard drives with 16 to 24 TB. They cost between 13.43 euros/tbyte (Seagate Barracuda 24TB (from € 320.36)) and 14.74 euros/tbyte (Seagate Barracuda 16TB (from € 235.77)), reproduced models excluded. Toshiba and Western Digital demand a little more.
Mini laser enables higher storage density
At the Heat Assisted Magnetic Recording, a mini laser heats up the panel surface in every head shortly before describing over 420 ° C. As a result, Seagate can magnetize smaller points with a more compact writing head. As a result, the data density increases, which enables the 30 TB on ten slices within a 3.5-inch case. Seagate relies on conventional description of the data on the windows (Conventional Magnetic Recording, CMR), without overlapping data traces.
As an alternative to the 30 TB models offers Seagate variants with 28 TB and the same HamR technique. At least at the moment, these are not attractive in terms of price compared to the 30 HDDs. The Exos M 28TB (from € 793) is currently overpriced and the Ironwolf Pro 28TB (from € 603.83) Hardly cheaper than the 30s.
