I recently bought a new SanDisk Ultra Flair USB 3.0 Pen Drive (32GB). I had no need but I got it to review for you people.
This pen drive/flash drive comes in different variants i.e. USB 3.0, and USB 3.1 Gen 2. So, I got the most popular one and reviewed it here on my two different computers. I personally found this flash drive pretty reliable and good-looking.
Let’s first clear some important things about its naming because it literally is pretty confusing.
This pen drive is basically a USB 3.0 Pen-Drive. But, when you open this drive on your computer, you may see USB 3.2 Gen 1 written along with it. Basically, USB 3.0, USB 3.1 Gen 1, and USB 3.2 Gen 1 have the same maximum speed i.e. 5 Gbps.
The company claims that this drive can offer you up to 150 MB/s read speed which I almost achieved in my testing. So, without any further delays, let’s get started.
This pen drive comes in five storage variants i.e. 32GB, 64GB, 128GB, 256GB, 512GB.
|Storage Variants||16GB, 32GB, 64GB, 128GB, 256GB, 512GB|
|Speed||Up to 150MB/s|
|Compatibility||USB 3.0 and USB 2.0|
|Software||Sandisk Secure Access and Rescue Pro|
|Warranty||5 Years Limited Warranty|
The drive is pretty lightweight and easy to carry. It has a mixed body made up of metal and plastic. Its dimensions are mm 21.13 x 42.42 x 60.6. I like the way they have designed this drive to be more sleek and compact.
I have tested this drive on my Windows Test System which I have built recently. Below are the specifications.
CPU: Intel Core i5 12700K
Motherboard: MSI Pro Z690-A DDR5
OS: Windows 11 Pro
RAM: DDR5 4200MHz 16GB
Storage: 1TB Silicon Power Gen 4 NVMe SSD
Benchmark 1: AJA System Test Score
Results: As the company claimed, this drive is capable of reaching around 150 MB/s read speed. I am really impressed by the numbers because not all products will reach their theoretical potential at all.
Benchmark 2: CrystalDiskMark 8.0.4
Results: I ran a single CrystalDiskMark test on this drive and I knew it is capable of offering more than what the company has to say. I used the 1 GiB test and the results are in front of you. The random read/write speed is low as expected with any USB drive. But, the sequential read and write speed is totally acceptable.
Benchmark 3: ATTO Disk Benchmark
Sequential Read Score
For this test, I used block sizes from 512B to 64MB. The queue depth is 4 and the chart below shows both read and write performance scores. Generally, this test is done using 128K block size with different queue depths but this one is done with a single queue depth with different block sizes.
4KB Random Read/Write performance
As you all know, the random read/write tests are done with 4KB block size universally. So, I changed the Queue Depth between the range of 1 and 32. Below is the chart showing the results.
The results are pretty stable because this drive is designed to work on very low random read/write speeds. You can expect below 10 MB/s read speed when you are working with too many files of different types.
What do I think about this pen/flash drive?
I am using this drive for quite a while and I found it really impressive. I have used it to move very big files from one system to another. It starts to heat up a little when put under a huge load but that’s normal with all the USB drives.
The performance is constant. I literally haven’t seen any performance drop while moving any kind of files. Sandisk Ultra Flair drive is great for personal as well as professional usage. So, I can definitely recommend this product to you.
I got my 32GB Sandisk Ultra Flair just for around 8 bucks. The 3.1 variant is going to be a little expensive. It is perhaps the best price you can get to see for this kind of high-performance drive.
Should you buy it?
Definitely, this product is really a perfect option to choose. It is inexpensive yet high-performance. It has got 5-year limited warranty as well. You have seen the benchmarks and I think this speed is more than enough for most of the users. If you need more speed, you can go for the USB 3.1 variant.
