Why HDD is Better than SSD


We typically speak concerning the a lot sooner speeds of SSDs, their more and more reasonably priced price ticket, and the various different advantages of SSDs. But if they’re so good, then why haven’t these drives changed standard exhausting drives but? The factor is that HDD additionally has its benefits. And the advantages are very vital. We will inform you about them right this moment. You may have each of them on the identical PC.

Solid state drives have all the time value way more than exhausting drives of the identical measurement. Although, over time the distinction in value between them grew to become much less and fewer, and the SSD itself has lengthy ceased to be a luxurious, you possibly can nonetheless lower your expenses when shopping for an HDD. And save quite a bit.

For instance, a 1TB WD Blue exhausting drive at the moment prices about $4,500, whereas a 1TB SSD from the identical collection will set you again $13,000. The distinction, as they are saying, is apparent.

If you want a drive for a number of tens of terabytes, then you definitely merely can not do and not using a exhausting drive. Even right this moment, client SSDs are very restricted of their capability, and also you merely gained’t discover a 10 or 20 TB drive like this.

No, after all, high-capacity SSDs do exist. But virtually all of them are designed for company customers, use the U.2 server connector and value like a Boeing wing. For instance, how do you just like the 12.7 TB Micron U.2 SSD for $4800? A 30TB SSD from Samsung for $20,000?

In the case of HDD, there is no such drawback in precept. For instance, a 18 TB WD Gold exhausting drive prices about $31,000.

3. HDDs are higher fitted to archiving and long-term information storage

Hard disk non-volatile reminiscence is greatest fitted to the long-term storage of knowledge. You can safely write information to the HDD, disconnect it from the PC and put it on the shelf for years to come back. Try this trick with an SSD, and in a number of years, you’ll have to face the tough actuality. There can be no info left on the strong state drive.

Research by JEDEC’s Alvin Cox confirms that beneath preferrred circumstances, strong state drives can retailer info for about 105 weeks, or simply a few years. And in some instances, they start to lose it as early as per week after the ability is turned off.

4. Ability to get better information after a failure

If, within the occasion of a tough drive failure, it stays doable to get better misplaced information by yourself or with the assistance of specialists who will instantly learn them from HDD pancakes, then within the case of an SSD, you possibly can face an actual catastrophe. Well, customers of solid-state drives with TRIM or information encryption may have the worst.

It’s all concerning the utterly totally different ideas of recording HDD and SSD. Unlike standard exhausting drives with comparatively sequential information writes, SSDs write information in blocks that may reside on totally different reminiscence chips. And on one chip, there will be no query of any linear recording. 

In this case, info is always overwritten, transferred from one reminiscence cell to a different, and when executing the TRIM command, it could possibly even be completely deleted. If we discuss HDD, then they delete info solely when it is overwritten.

5. HDD failure won’t come as a shock

In most instances, the “death” of a tough drive is preceded by:

  • all kinds of knocks,
  • whistles and squeaks,
  • pc freezes,
  • unnaturally gradual operation when the PC accesses the problematic drive.

A strong state drive has no such options. It dies quietly and rapidly, and you’ll solely learn how way more it is going to final by always monitoring the experiences of proprietary software program or utilities corresponding to Crystal Disk Mark. But just a few do that, so normally, the demise of an SSD will come as a whole shock to you, and the knowledge saved on will probably be immediately misplaced.
