How many hard drives can be connected to your computer

SSD in a computer. pros and cons

I have felt the convenience of using PC with two drives in the late 2000s, when in addition to the main HDD on 120 GB I bought the second second second used IDE HDD on 80 GB. In the noughties a PC was often seen as a luxury, especially in the outback, and a PC with two HDDs was a gimmick to my friends and it was perceived as excessive.

However, I quickly tried the convenience of downloading movies to an additional drive, when nothing slowed down the system. The Internet was very slow back then, and downloading movies and games from the DC file sharing network stretched for days and even weeks.

Since then I had many different drives in my PC, but one thing did not change. There were two or more. Even with all the SSD’s going around, I still stand by my principle.

I often upgrade computers and laptops for friends and acquaintances, getting their old components for the work. And the time came when many of them were not enough of the old SSD to 120 GB, which gradually moved to me. In 2019, for a while I had as many as three small SATA SSDs in my PC.

But this spring I bought a roomy 1TB Samsung 860 EVO and “scattered” the old SSDs over the PCs and laptops of the household.

But the fastest ones are. Samsung 850 EVO 120 GB I left in the main PC and now I will tell you about the pros and cons of this solution. But note that both my SSDs are with SATA III interface and almost identical in speed specs.

Hard drive specifications

Firstly I will tell you about the characteristics of hard drives and which of them are important, which are not, and which are not worth paying attention to at all.

Capacity. One of the key characteristics determining how much data can be placed on the drive. Up-to-date hard drives are represented mainly by the models from 0.5 to 18 terabytes, and with today’s data volumes, buying an HDD of 2 terabytes or less is not very rational. In addition, the most profitable by the conditional “cost per gig” are devices from 3 to 8 TB. If you don’t store a ton of media content on your PC, your choice is a 3-4 terabyte HDD. If you like me are storing, then buy several 6-8 terabyte “hard drives”, but not any. read on and you’ll see what I mean.

Price. Here everything is clear, but I’ve already told you about the most profitable solutions to buy. But the situation may change, for example due to discounts and promotions.

Speed. I’m not talking about spindle speed, but sequential read and write speed. Before the advent of fast and affordable SSDs, this was also a major consideration, but nowadays you can pay very little attention to the spindle speed, which is the same as the spindle speed, by the way. There are no especially slow HDD on the market (except SMR), and if you need speed. buy SSD; SATA-versions are much faster, and M.2 PCI Express dozens of times faster, and we’re talking about sequential operations, if we’re talking about random, the difference is even more impressive.

Cache capacity. Another feature which has practically lost its importance with the OS, programs and games migrating to SSDs.

Intease. We are only interested in SATA III for PC since SAS is a server slot.

Form Factor. 3.5-inch hard drives. for computers, 2.5-inch. for laptops. You can install a 2.The 5-inch model and into a desktop, but there is no sense in it: the only advantage of this form factor is the miniaturization. Otherwise, larger HDDs are better. they are bigger and faster. Simply put, if there is a free 3.5 or 5.25 slot. for PCs we always take 3.5″ hard drive, but you need a sled in this case too.

Filling. Can be air or helium. The trick of helium is that its density is much lower than air density, which means that you can fit more “pancakes” into the hard drive’s case, also the power consumption and vibration level are reduced. Nevertheless, helium has a significant disadvantage. it is able to seep even through solid metal, albeit very slowly. For a couple of years it is not a problem, and helium HDDs are on average even more reliable than classical ones, but what will be in the long run is unclear, so in my opinion it is better not to buy helium hard drives for home PCs, especially as there are enough good options among 6-8 terabyte models, and hard drives with more modest capacities do not need helium at all. However, if you refer yourself to the innovators and like to take the risk. you can take a helium HDD, but back up important data from it, as well as from any other.

Type of Recording. There are classic and Shingled Magnetic Recording (SMR), with partial overlapping of tracks. This is a critical parameter and my recommendation is simple: do not buy SMR-drives for any scenario except for those where you write something to them once and will not rewrite them again. In home PC this scenario is rare. more likely for archives and data centers.

Let me answer why I am so categorically against hard disks with tiled recording type. When overwriting any data, when the CMR-buffer is exhausted, such hard drives have to overwrite many more tracks than ordinary drives. not only the target track, but also neighboring tracks. So, write speed decreases many times and with large amount of data and its fragmentation becomes unacceptably slow, and disk may freeze or crash out of system, after that only turning PC off and on again will help.

Important: Don’t buy tiled (SMR) hard drives for gaming, home or office PCs. their performance when rewriting large amounts of data is extremely low and operation stability leaves much to be desired. Fate of such HDDs is for usage scenarios “once recorded information, then you only read it”. An almost complete list of SMR drives can be found in this article on Habra.

We can also mention microwave or laser heated recording, but solutions with these technologies are just starting to hit the market and it is too early to consider them for home PCs.

Purpose and mode of operation. For some hard drives the manufacturer has specified the intended operation mode as “8 hours a day”, but for others it is 24/7. We are of course only interested in the second case, so I would not recommend buying Seagate Barracuda and WD Blue. Personally I rarely have a computer that shuts down, and I would imagine that most people do too. As for the purpose. some HDDs are positioned as desktop, others as dedicated for video surveillance systems, some. for NAS, others. for servers, and so on. You should not pay too much attention to it, but it is necessary to look at the accompanying characteristics: for example some server disks are fast but very noisy, and some NAS Western Digital Red disks use the tiled recording type.

Noise level. It is better if it is up to 30 decibels, at most up to 35, though it all depends a lot on your case and subjective perception. Read reviews and reviews. sometimes the manufacturer claims the model to be quiet, but in fact it makes unpleasant and quite loud noises. e.g. crunching or clicking.

Manufacturer. The choice of manufacturer is largely a matter of personal preference. I’ve had several Seagate hard drives die in the last 15 years, 2 of them without warning in Smart, while WD has not died, although I bought more of them, but probably there are users who have it the other way around. I never bought a Toshiba and have no plans to buy one now. its low price and bad reviews make me suspicious. Would you tell us in the Комментарии и мнения владельцев what kind of hard drives you had and which brand’s solutions you think are more reliable??

How to connect 2 disks to the notebook (HDD HDDD or HDDSSD)

Question from the user

Hello.

How is it possible to connect one more disk to the laptop (or is it impossible)?? My 500 GB drive was just not enough, so I am thinking of expanding the capacity.

Svetlana.

Yes, such questions are not uncommon. In general, laptops have become very popular lately and are slowly replacing regular PCs. Laptops have a lot of advantages, but with the upgrade. the matter is complicated. Add another drive or change the memory. in some cases it is not possible at all. #x1f440;

It is a pity, the author of a question has not painted more concrete an essence of the problem. So in this article, I’ll look at a few ways you can connect another drive to your laptop (in some cases, you may have three at once)!).

By the way, many people connect an extra drive to their laptops. disk not only to increase the space, but to speed up the system (they put an SSD and #x1f4cc;transfer Windows from the HDD).

How to connect a second hard drive to your computer, laptop

You can never have too much disk space!

This truth has never been so true in the last 30 years. Despite the development of the IT-sphere (cloud disks, network storage, high-speed Internet) we are still confronted with the lack of free space on HDD. #x1f440;

The evident solution of this problem is to buy and connect another disk. But, as in any issue, there are nuances. Actually in this article I decided to consider this question in detail (so that the article would be understandable to most inexperienced readers).

#x1f449; Note!

Note that the disk space can be “lost” due to less than optimal Windows configurations (for example swap and hibernation files bloat), or due to a large amount of. I recommend to clean the trash and optimize the OS (how to do it) before buying a new HDD (it is possible that there is enough free space for all your tasks).

How to connect a hard drive to a USB port

Good day!

Today’s article is quite practical: it is not so rare the need to connect the hard disk (HDD) from the computer (laptop) directly to the USB-port (for example, to transfer a large amount of data from one PC to another, to recover information, to cure viruses, to create backups, etc.).д.).

Also, as an option, you can simply remove the drives from an old PC/laptop and use them as external drives (convenient for transporting large amounts of information). Why not?! (why spend extra money on an external drive when you can use an old one. ✌)

In this article I wanted to give a few options to solve this problem. In general there is nothing complicated about it, but there are certain features which I will try to focus on.

How to add another hard drive

On most computers and on some laptops, the user can add a spare Hard drive. If only a number of conditions are met.

  • The connection type of your motherboard and hard drive must be the same. Totally 2 types: ancient IDE (used in computers older than 15 years, you can tell it by the thick cable from the set of cables) and modern SATA (connected by 2 thin wires).
  • Unused connectors of the right type for the motherboard.
  • Unavailable ports in the power supply. if the power supply fails to power the drive, it will not start.

On a laptop

Not every notebook PC can have an extra hard drive, because it requires free space. It is quite easy to connect the Hard wherever there is a disk drive. Here it is necessary to “sacrifice” the DVD-drive. then there is a place for an HDD or SSD. It is done in this way:

  • You should purchase an adapter for the hard drive into the drive.
  • Carefully remove the disk drive by unscrewing the screw in the middle of the bottom of the laptop.
  • Install the hard drive in the adapter.
  • Insert the adapter in place of the notebook drive.
  • Format Hard and start working.

Many manufacturers sell a laptop without a disk drive, and some offer a hybrid approach with the main SSD drive and an HDD in the “vacant place”. Then the user can easily expand the memory of the laptop by replacing the complete Hard drive with a third party one.

If in place of the disk drive, you will have to make do with external drives. Specialists will not undertake such a risky business, because to add a hard drive, they will have to remove some parts.

Connect here is easier because there is more free space. This is done in six steps.

  • Turn the power off and remove both covers.
  • There will be several “s” on the front where you can place the hard drives, and access to the “motherboard” on the left.
  • Install the Hard in the bay, bolt it in place.
  • Connect the extra hard drive to both the motherboard and the.
  • Power on your computer and format the second drive.
  • Right click on its icon (PCM) and select “Create New Volume”.

If you have an older computer with IDE-type connection and only one slot left, you have the possibility to install two hardware on the same loop. It can be either 2 HDDs or a hard drive with an optical drive.

You can also install a 2.5″ HDD, but in this case a special adapter is required. To install the HDD, it is necessary to remove the side cover, place the drive in a recess and secure it with screws or clips (in more expensive models of cases). Then proceed to connect cables to the motherboard and the HDD itself.

When connecting the external hard drive to the computer or laptop, you must connect the cable, using a USB or mini-USB plug, to the drive on one side, and the other end of the cable, with a USB plug, connect to the USB port of the computer. Then wait for the computer to detect the new device.

  • Install the SSD in a special. connector (M
  • Connect the external HDD/SSD to the USB-port
  • Install another disk instead of the CD/DVD drive.
  • Bottom line (important)

You can install additional hard drives on the desktop computer. This setup requires that you configure each drive as a separate storage device or connect them using RAID configuration, a special method of using multiple hard drives. Hard drives in RAID configuration require a RAID-enabled motherboard.

There is no limit to the number of operating systems you can install, you are not limited to one. You can insert a second hard disk into your computer and install an operating system to it, selecting which hard disk to boot from in the BIOS or boot menu.
