Does it make sense to buy an SSD as external hard drive?
Today, many would be tempted to purchase an external SSD to store their content. However, there are several reasons why traditional external hard drives, like the Transcend StoreJet 25MC (SJ25MC), are still relevant today. For starters, this external hard drive offers 1TB of storage space. An external SSD that features the same amount of storage space would likely cost double. Additionally, while SSDs are indeed more durable, the SJ25MC comes with military-grade shock resistance, thanks to its hardy silicone outer case and built-in three-stage shock protection system.
Speed: Mechanical disk vs SSD
It’s also common knowledge that SSDs offer faster transfer speeds than HDDs, but when you’re using an external drive, the speeds are limited by the USB interface, which means both SSDs and HDDs provide the same maximum transfer speeds in an external form factor. In the SJ25MC’s case, it comes with a USB 3.0 Type-C cable, allowing for a theoretical maximum transfer rate of 625MB/s. Other features of the SJ25MC include a Quick Reconnect button that allows you to quickly reconnect the drive upon performing a ‘safe removal’ via Windows OS. This eliminates the need to unplug the drive.
In terms of performance, we performed our usual CrystalDiskMark test, which ran at nine cycles of the 4GB load. Here, the SJ25MC was able to give us a read and write transfer rate of 142MB/s and 136MB/s, which is respectable for an external drive. As for our real-world test, we timed how long it would take to transfer about 40GB worth of files to the device. It managed to do so in just under six minutes, at a transfer rate averaging 130MB/s.
