Lexar 64GB JumpDrive P20 USB 3.0 Flash Drive Review

Add Your Comments

Today’s review sample, straight from Lexar, is the next in my saga of super fast flash drive reviews. This bad boy, the 64GB P20, runs at USB 3.0 and is touted to be “Among the fastest USB flash drives available…” so you’d better bet I’ll put their claim to the test! Here goes nothing, boys and girls.

Specifications and Features

There hasn’t been word from Lexar as to what controller and NAND are in use in the P20, but I feel like it is a different controller from the Phison S8 we’ve seen in the last couple of reviews. You’ll see why before long. With a speed rating of 400 MB/s sequential read and 270 MB/s there is no doubt the Lexar P20 is going to be a blisteringly fast drive. One large advantage over most competitors is the limited lifetime warranty offered by Lexar on this drive, way to stand behind your product!

The specifications and features below come directly from the Lexar website.

Retail Packaging

Taking a look at the product box for the JumpDrive P20 we can clearly see the product itself displayed. The outer shell is a clear plastic with some white print on it. The inner packaging is a black, molded plastic. On the back side, inside the outer sleeve, is a sheet with features and specifications. There is also a flip-up tab on the rear for hanging on a pegboard in a brick and mortar store.

The Lexar JumpDrive P20

For the P20, Lexar opted to keep things simple. On the product front there are only two features; the white Lexar logo and the slider to open the flash drive. The whole front is constructed from black, injection molded plastic. Turning to the rear we see a one-piece, aluminum case which the black plastic of the front snaps in to. The JumpDrive P20 is built solid and will last a long time. It has a heavy feel in-hand, most likely due to the thickness of the aluminum casing. Also formed in the aluminum is a lanyard hole, of which one is included as well.

Benchmarks

All of the benchmarks seen below are run with the JumpDrive P20 plugged in to the rear USB USB 3.1 port of the motherboard. Before testing the drive was quick formatted to exFAT with the default allocation size to make sure everything was clean and consistent.

CrystalDiskMark (CDM) is run at its standard settings. The beauty of this benchmark is that the data is completely incompressible. This makes these tests more like a real-world situation instead of attempting to maximize throughput for a spec sheet. The JumpDrive P20 performed very well here, nearly reaching sequential specifications for max speed. The 4K read speeds were better than most drives I’ve tested, but the 4K writes were definitely lackluster.

AS SSD is next up on the list and shows a very similar story to the CDM results above. Sequential speeds were solid, with the write speed merely single digits from eclipsing the max. Again 4K read performance is solid here, but the write for 4K and access time were… bad.

Third up in our test suite is HD Tune Pro. Here we test with the Random data pattern, this shows more real-world information than a steady stream of the same compressible data. The sequential performance here was outstanding, with the write speed passing the max! On the 4K performance; read IOPS were incredible, but the write IOPS were lacking.

ATTO Disk Benchmark is typically used by manufacturers to showcase their drive specs as it uses compressible data in a sequential test much like AS SSD does. That being said, the JumpDrive P20 came in lower on read speeds than I expected here, but writes were better than expected.

Comparison Data

As a “baseline” to compare the P20 with I pulled out my trusty 16GB SanDisk Extreme USB 3.0 Flash Drive. This is a flash drive that I’ve used since August of 2013.

For the second comparison data, I used the results from the previously reviewed 256GB Patriot Magnum 2 USB 3.1 Flash Drive.

For the third comparison data, I used the results from the recently reviewed 256GB Mushkin IMPACT USB 3.0 Flash Drive.

Results in the graphs are normalized to the Lexar JumpDrive P20 results, so those all show 100%. All results except the Access Time are “higher is better,” those are “lower is better.”

As a second comparison a real world situation was approached. A backup folder from my server was copied to each flash drive and timed, so this result is “lower is better”. By my stopwatch the JumpDrive P20 finished the transfer in 7:02.92 (mm:ss) while the Sandisk finished in 5:42.84 and the Patriot finished in 13:43.58. The folder is 5.50GB and contains 6,670 files in 1,080 folders and results here were surprising, I honestly did not expect the P20 to finish the test in almost half the time of the Patriot. This is proof, in the real world, 4K and sequential numbers aren’t the be-all of performance. I’m also glad to say, this is the first hyper-fast flash drive to come close to my Sandisk Extreme USB 3.0 in real world testing.

Conclusion

In synthetic benchmarks the P20 had a few stumbling blocks in the small-file write performance. I’m glad the stumbling halted in the synthetic benchmarks because I would much rather see real-world performance than synthetic performance. Sure, synthetics look great on paper, but for the vast majority of users what counts is how the drive performs in-use. Built on one of the best, if not the best, cases I have ever felt for a flash drive the JumpDrive P20 rounds out to be an amazing product. This review sample was 64GB, but it is also available in the 32GB and 128GB flavors.

As far as pricing goes, this drive is available direct from Lexar for $54.99, but I also found it at B&H for $37.68. For performance of this level, at under $0.60/GB, the JumpDrive P20 is a hard product to beat. It definitely gets the Overclockers Approved stamp.

  1. All Intel ports are using the same driver and should perform better than any non-Intel controllers.

    I'm not sure why only in ATTO are worse results as in other benchmarks are about as high as it should be.
    Sau khi sinh con đầu lòng, tôi mất ngủ 3 tháng liên tục vì bé khóc dạ đề. Vợ chồng tôi khôn cùng stress vì mỗi đêm con khóc nhưng làm mọi cách mà cứ đến giờ là bé khóc ngằn ngặt không thể dỗ nổi. Ông bà nội ngoại ở xa lại có tuổi nên vợ chồng tôi phải tự tìm cách xoay xoả. Thuê người giúp việc thì chả ai chịu được quá 1 tuần hoặc nếu có làm thì chỉ đồng ý trông bé ban ngày chứ không thức đêm. Tôi bị chứng rụng tóc sau sinh. thời kì đầu chăm con quả thực khiến tôi mỏi mệt cả về thể chất và tinh thần. Tôi bị ám ảnh bởi tiếng con khóc và mất ngủ liên miên. May sao hết thời gian này thì nói trộm vía bé rất ngoan, ăn ngủ đúng giờ và không còn quấy khóc đêm nữa. Vợ chồng tôi cũng tìm được người giúp việc rất ưng, bác chịu thương chịu khó và yêu trẻ nít nên tôi đã có thể yên tâm đi làm trở lại.1 tuần trước khi đi làm, tôi tự thưởng cho bản thân một ngày đi mua sắm xống áo. Tôi khá tự tin với vóc dáng sau khi sinh, mặc dù tăng đến hơn 20kg lúc mang bầu nhưng thời kì chăm con vất vả nên tôi đã giảm về mức cân như thời con gái. Ngắm mình trước gương tôi thấy vui lạ lùng nhưng tôi giật mình khi nhìn thấy mái tóc dày, suôn mượt trước kia lộ rõ ngôi tóc lúc buông xõa. Hóa ra bao bấy lâu tôi bận chăm con và luôn sát sao với tóc búi, buộc cao nên chả có thời kì để ý tóc mình đã rụng nhiều đến vậy... Tôi gọi ngay cho cô bạn thân từ thời cấp 3 mới chuyện trò với tôi về cách chữa rụng tóc hiệu quả mà cô ý đang áp dụng. Cầm sản phẩm Lược laser Hakiba trên tay và được tư vấn tận tình bởi nhân viên của hoidau.vn tôi cảm thấy rất tin cẩn. quả tình Lược laser Hakiba đã giúp tôi tìm lại mái tóc thề mà tôi nghĩ rằng sẽ chẳng bao giờ có lần thứ hai.Sau 5 tháng dùng tóc tôi đã mọc dày trở lại, rãnh ngôi không còn lộ rõ chân tóc, tóc giảm rụng đến 90%. Tôi hoàn toàn ưng với hiệu quả mà sản phẩm Lược laser Hakiba mang lại. Đây là bức ảnh tôi tự chụp để theo dõi trong quá trình trước và sau 5 tháng sử dụng Lược laser Hakiba.
    Huh, I'm not sure what the deficit is there, but it's definitely consistent across all testing.

    I'm on the USB 3.1 port, as stated in the review, I wonder if the native 3.0 port is faster.
    Here is result made on ASUS GL552VW laptop ( on battery ). My P20 has nearly a year and is ~85% full but still can reach 300MB/s read in queue depth 4 and 275MB/s in 10:

    On desktop boards with Z170 chipset should be better results. At least on Z170 OCF I have up to 50MB/s higher max bandwidth on various USB storage devices than on this laptop.
    I'm not sure why your ATTO results are so low. I had no issues with that when I was reviewing P20 about a year ago:

    That was on ASRock Z97 OCF.

    Since I'm using Jumpdrive P10 and P20 which look about the same, I will only add that they're really solid. I'm using both almost everyday - P10 for nearly 2 years while P20 for about a year.
    The read speeds are the same across all models of the Extreme, but the write speed goes up as capacity does.

    It is definitely a solid drive, but a different type of fast from what I've been receiving for review. This Lexar is the closest thing I've seen to the Extreme, all the others looked a lot better on paper than they were in realistic usage.
    Thanks for including the Sandisk Extreme in the comparison. I bought the 64GB version several years ago and it seems like it remains a strong contender.

    One thing I will add is that I have done some comparisons amongst USB drives and microSD cards in the range of 64GB and smaller for the purpose of choosing storage for a Raspberry Pi and have found that some drives exhibit a marked drop in speed between the 6$GB and smaller models. I wonder if the Sandisk Extreme is like that. If so, the 64GB Sandisk extreme might compare even better.
