After the success of the SD Card (Secure Digital Card), the miniSD Memory Card was developed to meet the demands of the mobile phone market. The MiniSD Card provides the same benefits as the SD Card, but is smaller than the original SD Card. MiniSD Cards are typically found in many newer mobile phones with features such as built-in digital cameras, downloading and games, basically the mobile phones where the miniSD can meet the requirements for increased data storage. MiniSD cards are 21.5 mm x 20 mm x 1.4 mm and generally provide 16MB to 256MB of storage.
Mainly used in mobile phones and other small handheld devices the MicroSD format is currently available in capacities up to 4GB, and it roughly 1/4th the size of the SD card at 15mm W 11mm W 0.7mm. The MicroSD card is also the smallest memory card available.
Card adapters can be purchased that enable backwards compatibility — this would allow MicroSD cards to work in SD and MiniSD slots, and also for MicroSD cards to work in SD card slots.
Buying a New Hard Drive for your PC?
7 Things You Must Know About HDD & SSD’s
All hard drives die. It’s a fact of life, and it’s normal to purchase a new one every few years, either to replace an old hard drive or to use as an additional backup drive. But with so many choices out there, which hard drive should you buy?
The good news is, hard drive shopping isn’t all that difficult. In fact, there’s a lot of flexibility and leeway! As long as you follow these guidelines, you won’t have to worry about buying the wrong hard drive and throwing away your money.
1. Hard Disk Drive vs. Solid State Drive – SSD
The absolute first decision to make when buying a data storage drive is whether you want a solid state drive (SSD). While an SSD serves the same function as a traditional hard disk drive (HDD), it comes with a few pros and cons.
An SSD is a type of data drive that uses flash memory instead of the spinning metal disks found in traditional HDDs. Think of it like a massive USB drive or SD card. But how important is that distinction, anyway?
Well, there are benefits. First, SSDs read and write data faster. Second, SSDs draw less power which conserves energy and extends laptop battery life. Third, SSDs have no moving parts so they make no noise and have longer lifespans.
2. Hard Drive Sizes and Interfaces
Once you’ve decided between HDD and SSD, you have to pick a form factor. Thankfully, there are only two choices and the right choice is mostly dictated by your current setup.
Data drives come in two form factors: the 3.5-inch drive and the 2.5-inch drive.
In traditional HDDs, data is stored on spinning metal disks, which means that more disks are needed for expanded data capacity. For this reason, desktop HDDs tend to be 3.5-inches with a general maximum capacity of 12TB while laptop HDDs tend to be 2.5-inches with a general maximum capacity of 4TB.
On the other hand, SSDs can be made smaller because they don’t require movable parts. As such, most SSDs come in the 2.5-inch form factor. What if you need to fit an SSD into a 3.5-inch connector? Adapters are available.
As far as connections go, most modern consumer drives (both HDD and SSD) use SATA connectors. Older HDDs that were created before the SATA standard most likely use IDE connectors instead. And if you’re buying an external drive, it will connect to your system through a USB port.
3. Hard Drive Specifications and Performance
Now that you know what kind of drive to buy, it’s time to find the best one that fits your needs. Here’s what you need to consider:
Storage capacity. HDDs come in all sizes, capping out at 16TB per drive due to physical limitations. On the other hand, SSDs are much smaller and have reached as high as 60TB—but affordable consumer-level SSDs are rarely larger than 4TB.
Transfer speeds. The performance of a consumer-level HDD is determined by many factors, but revolutions per minute (RPMs) is an important one. Higher RPMs means faster transferring of data to and from the drive.
You can ignore the drive’s SATA speed. For example, a modern drive might be listed as 3.0GB/s and 7200RPM. That first value is the SATA speed, which describes the theoretical maximum speed of a SATA connection. No HDD can transfer data at that kind of speed. However, a 7200RPM drive will always be faster than a 5400RPM drive.
Cache space. When a hard disk needs to transfer data from one section of the drive to another, it utilizes a special area of embedded memory called the cache or buffer.
A larger cache enables the data to transfer faster because more information can be stored at one time. Modern HDDs can have cache sizes ranging from 8MB to 256MB.
Access times. Traditional HDDs have a couple of other factors that impact performance, such as the time it takes for the reader to position itself to read data from or write data to the drive.
While it’s true that two 7200RPM drives could perform differently (e.g. one of them might be slower at re-positioning the reader), there’s no standard way to compare access times. Plus, most hard drives perform at similar levels these days, so don’t worry too much about this particular detail.
For SSDs, you’ll want to look for sequential read and write speeds (also called sustained read and write speeds). As long as those speeds are within the SATA connector’s max speed, which they most likely will be, you should be fine.
Failure rate. Since HDDs are mechanical, wear and tear is expected over time, but not all HDDs wear at the same rate. Some models are prone to fail within 12 months while others have average lifespans exceeding six years. It’s your responsibility to research this on a per-model basis prior to making a purchase.
4. Price and Cost of Hard Drives
When shopping, you’ll run into a wide range of hard drive prices for devices that all look very similar on the surface. It’s up to you to decide which factors and features are most relevant to your needs, then select a hard drive that fits those needs.
That said, one way to determine value for money is to divide the drive’s price by its storage capacity to get its price-per-gigabyte.
For example, consider the WD Black series of HDDs.
The WD Black 1TB HDD is an all-around good purchase for everyday consumers. Bumping up storage capacity to the WD Black 2TB HDD nearly doubles the price. Bumping up capacity again for the WD Black 4TB HDD costs you quite a bit more, but not quite double. The trend holds true for the WD Black 6TB HDD.
Which one of these offers the best value? The 6TB model. The 1TB, 2TB, 4TB, and 6TB models have price-per-gigabyte values that decrease with larger storage space. There are other drives that do not scale in price, though. So you have to be careful. Some drives cost more per-gigabyte at higher capacities.
It’s true for SSDs, too. The Samsung 860 EVO 250GB SSD is affordable, but the Samsung 860 EVO 500GB SSD grants twice the space for less than twice the price. And when you get up to the Samsung 860 EVO 1TB SSD, you get the best bang for your buck.
5. External Hard Drives vs. Internal Hard Drives
The final thing to consider is whether this hard drive is going to housed in a desktop or laptop case or used externally and connected to various devices. It’s an easy decision, but let’s take a look at the pros and cons of each.
External drives are ideal for storage, backups, and transfers. They typically connect using USB 2.0, 3.0, or 3.1, which have maximum transfer speeds of 60MB/s, 625MB/s, and 1,250MB/s, respectively. USB 3.1 is preferable of course, but not essential unless you’re transferring hours of data back and forth every single day.
External drives are portable. They can be shared between multiple computers without any hassle. Just unplug the USB, plug it elsewhere, and you’re done. They can also be plugged into TVs and media centers for direct media playback.
In all other cases, internal drives are preferable.
Note: Any data drive can be used internally or externally—external drives are essentially internal drives placed in a special protective casing. If you buy an external drive, you can actually remove the drive and use it internally.
We like HDDs for external drives because you rarely need the performance of an SSD when used externally, and HDDs tend to hold up better over time. Make sure you get one with USB 3.0 or 3.1 support, like the affordable Seagate Expansion 4TB Portable HDD.
If data security is your primary concern, you might consider something like the Transcend 1TB StoreJet M3 HDD. It comes with military-grade shock resistance, an anti-shock rubber case, an internal suspension system that can survive drops, and built-in 256-bit AES encryption.
If speed is of utmost importance and you don’t have that much data to store, then an external SSD may serve you better. These are rarer than external HDDs so pickings are slimmer, but good options do exist, such as the Samsung T5 500GB Portable SSD. Note that you must use USB 3.1 to take advantage of its full transfer speed.
6. Gaming Hard Drives: PlayStation, Xbox, PC
Your hard drive choice can significantly impact the performance of games, which is why we always recommend SSDs for gaming. This is true for PCs, Xbox One, Xbox One X, PlayStation 3, PlayStation 4, PlayStation 4 Slim, PlayStation 4 Pro, or any newer gaming console.
Since SSD speeds far exceed HDD speeds, games will launch much faster and load much faster between levels, stages, and maps. Seriously, the difference between SSDs and HDDs for gaming is night and day. You’ll regret getting an HDD!
When choosing a drive, you have to stick to the parameters of the device:
- For PCs: Any hard drive will work as long as you know the form factor of the hard drive bays in your case and the connection types on your motherboard. Again, it’s most likely 3.5-inch for desktops and 2.5-inch for laptops and most likely SATA connections.
- For Xbox 360: The original Xbox 360 uses 2.5-inch hard drives set within custom cases. To upgrade or replace, you’ll need to buy one of Microsoft’s overpriced replacements. Third-party drives can be used but need to be applied with Xbox-compatible firmware, which is far beyond the scope of this article.
- For Xbox 360 S and E: The hard drives used in Xbox 360 S and E consoles are incompatible with the original Xbox 360, and vice versa. The 4GB models have internal flash memory that can’t be removed or replaced. The 250GB models can be upgraded to 500GB by purchasing one of Microsoft’s overpriced replacements.
- For Xbox One: The Xbox One supports external drives through USB 3.0, which means you can use pretty much any SSD. Unfortunately, there’s no easy way to replace the internal drive. Learn more in our article on taking advantage of Xbox One external drives.
- For Xbox One X: The Xbox One X also supports external drives through USB 3.0 with a minimum size of 256GB. Unfortunately, there’s no easy way to replace the internal drive, and doing so will void your warranty.
- For PlayStation 3: All PlayStation 3 models have 2.5-inch SATA drives that can be replaced and upgraded by users without hassle.
- For PlayStation 4: All PlayStation 4 models, including Slim and Pro, have 2.5-inch SATA drives that can be replaced and upgraded by users without hassle. They also support external hard drives through USB 3.0.
7. Internal and External Hard Drives for Mac
If you’re on a MacBook Air, MacBook Pro, Mac Mini, or iMac, then there are a handful of extra considerations you should keep in mind when buying a hard drive.
Internal Mac Hard Drives
All MacBook Air, MacBook Pro, Mac Mini, and iMac models 2012 and later use an internal 2.5-inch form factor (except for 27-inch iMacs, which use an internal 3.5-inch form factor). Fortunately, 3.5-to-2.5-inch adapters do exist.
Things get a bit murky as far as SATA, PCIe, NVMe, and AHCI are concerned. For example, 21.5-inch iMacs in 2017 only have a PCIe slot if the device was initially fitted with a Fusion Drive. You won’t know which connections are available in your exact device unless you specifically look it up.
External Hard Drives for Mac
For external drives, you have several connection options, listed in order of increasing data transfer speeds: USB 2.0, USB 3.0, USB 3.1, Thunderbolt 2, and Thunderbolt 3 (also known as USB Type-C). We recommend USB 3.0 as the absolute lowest you should go.
Mac devices use Apple’s unique file systems, so external hard drives ought to be formatted in either HFS+ (Mac OS Extended) or Apple File System (APFS) for maximum performance.
