The T1 doesn't have all of the 850 Evo's features, however. Most noticeable is the omission of the RAPID mode, which uses the available system memory (RAM) on the host computer as an input/output cache to boost the drive's performance. Since this feature is only applicable for internal drives and the T1 works externally, RAPID is not implemented. This means it's likely that the T1's write performance will not be as good as its read performance.
Out of the box, the T1 appears to the host computer as a small FAT32 partition that contains the Samsung Portable SSD setup software. Once run, this application walks you through a few steps to set up the drive, including naming it and, optionally, picking a password to protect its content. Depending on the system you're using, be it a Windows or a Mac, the software will then reformat the drive into a new full-capacity partition that uses an applicable file system -- NTFS or HFS+, respectively. The whole process took me just a few seconds.
You can always use the Samsung Portable SSD application later to change the password option. If you choose to password protect the drive, keep in mind that there's no way to access the data on the drive if you forget the password. This is because the drive supports AES 256-bit, which is currently the strongest encryption standard.
The Samsung Portable SSD T1 totally delivered in real-world performance. When used with USB 3.0, it registered a sustained write speed of almost 160MBps and a read speed of close to 300MBps.
The T1 also works with USB 2.0 with a sustained speed of around 28MBps and 30MBps for writing and reading, respectively.
Note that while super-fast, the drive wasn't as fast as Samsung claims, which is 450MBps. When it comes to storage devices, however, it's quite common for there to be a huge disparity between real-world performance and the number the vendor claims. So far, the T1 is still the fastest on the market among non-RAID portable drives.
Super-compact, the Samsung Portable SSD T1 redefines portability. Super-fast, it raises the expectation of what a portable storage device is capable of. In fact, it's how any portable drive should be. The drive is perfect for those needing to quickly back up data or even do some video editing on the go.
My only minor concern is its three-year warranty. Considering Samsung backs the 850 Evo drive with a five-year warranty and thedrive with a 10-year, the T1 looks short-changed. Plus, of course, paying $600 for just 1TB of storage space is a luxury most people can't afford.
That said, the T1 is best suited for professional and high-end business users. For the rest of us, I'd wait till the price comes down before getting your own.
