What is a Portable SSD?
A portable SSD is a type of solid state drive that uses flash memory and is designed for external use. SSD stands for solid state drive, meaning it contains no moving parts unlike traditional hard disk drives. The “portable” part means the SSD comes in a compact, lightweight enclosure and connects via USB cable to a computer, laptop, or other device. Portable SSDs are also sometimes referred to as external SSDs.
Here are the key features of a portable SSD:
- Uses flash memory – This provides faster read/write speeds and better reliability compared to HDDs.
- Small size – Typically smaller than a smartphone, portable SSDs are lightweight and easily portable.
- Storage capacities – Ranging from 500GB to 4TB currently. Lower storage sizes are more comparable to flash drives.
- USB connection – Connects via USB 3.0, USB 3.1, USB-C, or Thunderbolt ports. No power cord required.
- Durable design – Designed to cope with bumps and drops making them ideal for on-the-go use.
- Compatible – Works with Windows, Mac, Android, Linux, and game consoles with USB ports.
The top brands for portable SSDs include Samsung, SanDisk, WD (Western Digital), Seagate, and LaCie. Prices range from around $50 for a 500GB model up to $700+ for high capacity 4TB options.
Advantages of Portable SSDs
Portable SSDs offer several benefits compared to traditional external hard drives and flash drives:
Speed
The main advantage of portable SSDs is much faster data transfer speeds. Whereas a typical flash drive maxes out around 200MB/s, portable SSDs can reach over 1,000MB/s. This speed advantage is due to the rapid read/write capabilities of flash memory combined with the USB 3.0/3.1 interfaces on new SSDs. For quickly transferring large files or folders, portable SSDs are 5-10x faster than regular flash drives.
Size and Weight
Being based on flash memory allows portable SSDs to be much smaller and lighter than external hard disk drives. Portable SSDs weigh around 1-2 ounces and are about the size of a small smartphone. This compact size makes them easy to tuck into a pocket or bag when on-the-go. External HDDs are larger, bulkier, and require external power, making portability more difficult.
Durability and Reliability
With no moving parts, portable SSDs are more durable and shock-resistant than external HDDs. Their flash memory can withstand bumps, vibrations, drops, and extreme temperatures much better than mechanical hard drives. They are better suited for travel and field work where reliability is important. Portable SSD failure rates are lower than portable HDDs.
Capacity
While not as spacious as desktop external HDDs, portable SSD capacities have grown in recent years. Entry-level options start around 500GB but 1TB to 2TB options are common. High capacity models are now available in the 4TB range, offering ample storage for personal media files, photos, videos and office documents. For just external storage and backup, portable SSDs provide adequate capacities.
Compatibility
Portable SSDs work reliably with all modern computing devices and operating systems that support external storage over USB connections. They can be plugged into Windows PCs, Mac computers, Android smartphones/tablets, Linux devices, Chromebooks, gaming consoles, smart TVs, and more. So they provide convenient external storage for virtually any device with a USB port available. Compatibility is excellent.
Can Portable SSDs Function as Flash Drives?
Yes, a portable SSD can readily function as an external flash drive. The main similarities that allow this usage are:
- Compact, lightweight design for easy portability.
- USB interface allows plug-and-play connectivity.
- Flash memory storage media.
- No external power source required.
With these characteristics, a portable SSD can fully replace a standard thumb drive or flash drive. You can copy files back and forth, store media files or backups, and carry it around in your pocket just like a flash drive. The experience is virtually the same aside from the faster transfer speeds.
Think of a portable SSD as a high-capacity, high-speed version of a flash drive. The functionality overlaps significantly. The only practical differences are the higher cost per gigabyte of portable SSDs and interface limitations on older PCs. But with USB 3.0 or USB-C, portable SSDs provide full flash drive capabilities.
Key Functions as a Flash Drive:
- Store and transfer documents and media – Portable SSDs have enough capacity to store photos, videos, music, project files and office documents. You can copy these files back and forth just as with a flash drive.
- Backup device – Use portable SSDs to backup important files from your main computer. The fast transfer speeds make quick work of backups.
- Transfer files between devices – Copy files between desktops, laptops, tablets, phones, game consoles and anything else with a USB port.
- Additional storage space – Plug a portable SSD into laptops, desktops, gaming consoles and smart TVs to significantly expand the internal storage capacity.
- Encryption support – Many portable SSDs offer hardware encryption to password protect your sensitive data.
- Ruggedness – Durable designs stand up to typical flash drive handling and transportation.
A portable SSD provides all these common flash drive functions while offering far greater speeds, capacities and reliability. The only limitations are slightly higher costs per gigabyte and lack of support for older USB standards.
Limitations of Portable SSDs as Flash Drives
While portable SSDs can readily replace flash drives in most situations, there are some limitations to consider:
Cost
The main drawback of portable SSDs currently is their higher cost per gigabyte compared to flash drives. A typical 256GB flash drive costs around $25 to $30 currently, or around $0.12 per GB. A comparable 250GB portable SSD costs around $60 to $80, averaging $0.25 per GB. So the storage capacity costs about twice as much. Buying higher capacities can help improve the value, but portable SSDs remain pricier.
USB Compatibility
Most new portable SSDs utilize the faster USB 3.0 standard, with some using the newer USB 3.1 or USB-C interface. Older PCs may only have USB 2.0 ports which run significantly slower – around 35 MB/s max. So you may not get flash drive-like performance plugging into older hardware. USB 2.0 is still adequate for documents but slow for media files. Checking port compatibility is important if using older computers.
Size and Weight
While highly portable, portable SSDs are around 4-5 times larger in volume than typical flash drives. And they weigh about 4-5x as much, around 1 ounce versus 0.2 ounces for flash drives. This may make them less ideal than flash drives for attaching to keychains as they add more bulk. But for most external storage needs, the small size shouldn’t be an issue.
Moving Parts
There are no moving parts within portable SSDs, but dropping them can still potentially damage components and stop the drive from working properly. They are much more durable than external HDDs but caution is still required when transporting them. Shock-resistant designs help minimize this risk however.
Overall, while pricier per gigabyte and requiring USB 3.0 ports for peak speeds, portable SSDs can readily replace flash drives in most situations. Their far faster transfer rates, higher capacities, and ruggedness make them excellent as high-performance external storage devices.
