This is the biggest and fastest SSD ever: 15TB at 6.8GB/s

If you are a user with high space needs, we are sure that this will come in handy, although you may not be able to pay for it as such if you are a common worker. And it is that Micron has announced what was expected, since it is not only the debut of a series of products as such, but of a new technology that is included in them. These are the Micron 7450.

And what’s new in them? Well, first of all, that it is a complete series that encompasses various capacities and form factors and that some are intended for data centers, SQL and NoSQL databases, virtualization or simply servers. But above all this is the fact of being the first series of the brand with TLC and 176 layers.

Micron 7450: SSDs that rival server HDDs


Just a few days ago we talked about the forecasts of Micron itself, to which Huawei was added for its data centers. Well, the smoke cleared and finally we have before us these new Micron 7450.

The figure is undoubtedly a record: 176 vertical layers with 3 bits per cell and especially in high capacity. SSD with QLC and said number of layers was already on the market from Micron itself with its 2400 series, but not with 15 TB and above PCIe 4.0 with devilish performance.

Sizes range from 400GB up to 15.36TB mentioned in three different form factors: U.3 7mm and 15mm, E1.S 5.9mm, 15mm and 25mm and M.2 with the most common for the gaming industry and 22×80 mm and 22×110 mm edition.

The curiosity of these SSDs is that of all the existing models and sizes there are only three of them that can be PCIe 4.0: the two in U.3 format (7 mm and 15 mm) and the 7.68 TB E1.S version . In terms of performance, there are also particularities to take into account.

Up to 6.8 GB/s and 1 million IOPS


The data here is quite interesting, because not everyone achieves the maximum possible speed. What is certain is that the models in form factor U.3 and higher capacity achieve the desired 6.8GB/s in sequential reading and up to 5.6GB/s in writing.

Where we do see a difference is precisely in the MAX range, since what improves in all the series presented is something very important, such as IOPS. Normally and as we see the capacity is reduced at the expense of achieving maximum performance. Thus, for example, within the U.3 in MAX, the maximum capacity would be 12.8 TB for the named speeds and the 1,000,000 IOPS in reading and 410,000 IOPS in writing.

In addition to this, we must count on the impressive durability that all the units show, since we are talking about a minimum of 800TBW up to an incredible maximum of 70,000TBW. Finally, we have to talk about the M.2 for PC, which are nothing that we have not seen in capacity or speed, but durability is another story. And it is that they will reach the 17,500TBWsomething that of course no common user will be able to achieve, where it could be said that we have SSD for all our lives.

On the other hand, there is not a single price data, which surely will not be cheap given the data shown just above.
