HIGH speed SSD - 405 (write) and 430 (read)
355717
Enclosure contains a Samsung 850 Pro SSD which was purchased for its reliability and speed. Unfortunately, the SSD's speed was limited by the original enclosure purchased.  The measured speeds (Mac) were about 235 (write) and 260 (read)... which was about half those stated on the drive specifications.  When I did a speed check of the internal Mac SSD, the speeds were 415 / 470 respectively... so about twice the speed of my external drive.  After several reviews and some investigation, I tried the Inateck, even though it was plastic instead of aluminum.  While I am still not convinced of the true benefit of the double USB 3 connector (standard rectangular on both ends), the speed is FANTASTIC!!! I highly recommend this enclosure to anyone wishing to take advantage of the benefits of their SSD.

Samsung EVOs are about the best SSDs out there. I've had two of them now, and am just flat amazed at how fast they are. I can regularly get well over 100MB/s transfer rates, and booting up is lightning fast. How did I ever survive with a spinning drive?

Beware - This is not Samsung "branded" so it is not fully supported in apps like Samsung Magician nor will you be able to get firmware updates from Samsung.  However it is extremely fast and I use it as my boot drive for Windows 10 without any problems on my MSI X99A Gaming 7 motherboard in PCIe mode.  My benchmarks:

Seq Read 2231 (MB/s), Seq Write 1562 (MB/s), Rand Read 110484 (IOPS), Rand Write 92908 (IOPS)

for comparison my 'regular' SSD; Intel SSDSC2CW120A3
Seq Read 535 (MB/s), Seq Write 516 (MB/s), Rand Read 52534 (IOPS), Rand Write 85955 (IOPS)

Using it in sata 2 connection on a 630amd and win 8.1. X64 loads in around 12/15 seconds.

It s my 3rd drive... The previous ones being Crucial. These sp perform as well

I have an SSD in my MacBook Pro. A disk speed test of my local disk shows around 720MB/s read and 700MB/s write speeds. The TarDisk gets around 70MB/s read and 24MB/s write speeds. That is incredibly slow. 10x slower than my internal storage. It delivers on the promise of expanding your disk, but those speeds are a killer for anything other than small documents. I have an external USB 3.0 disk that cost half as much as the TarDisk and clocks in around 80MB/s read and 75MB/s write. So, if your goal is to have an "invisible" storage device you can plugin and forget, it is a great choice. If you are looking for speed of access, steer clear of this one.

Bought this hoping to replace an existing drive and add some speed, however I get max 8Mb/s and between 3-6Mb/s regularly reliable device but slow.

I have both the 32GB and 16GB models - 37MB/s Write and 124MB/s read  while my Lexar USB 3 thumb drive gets 145MB/s write and 350MB/s read

Placed a 500GB SSD in here. Getting 80-140 MB/sec when plugged into my laptop.

Works good with HDDs, but when I tried to read an 850 EVO SSD through it, it was not working....

Works perfectly with Crucial/Micron M500 960GB. Getting about 450MBps read, and write speed is similar. Backs up 200GB of 1MB-100MB files in about an hour.

I've been doing software RAIDS for 20+ years. this is the first time I've ever seen drives fail to perform like this. By themselves these drives do 200/mbytes/sec 5mb/sec. impressive. Build an array with 2 and writes are 400mb/sec good, READS are 180mb/sec ???? ok I bought 3 and even in a 3drive stripe writes are 450mb/sec while READS fall to 120-160mb/sec. my previous array is 3 3GB Toshiba's from 2012 and they work as expected. tried different cases, reformatting and a few other things but get the same results. bottom line is don't buy for RAID use. OS X 10.13.4

the read and write sequential speeds are only about 100MB/s on my Thinkpad X220. I don't feel much faster than my origin HDD (Hitachi 7200rpm)

I will let my Performance Benchmark speak for itself.  Cloning was easy-peasy, lemon-squeazy.  Swap the drives and launched Samsung Magician.  Ran through the OS Optimization (EASY).  Set Over-Provisioning (one click / EASY).  Enabled Rapid Mode (one click / EASY).

Sequential Read = 5201MB/s
Sequential Write = 4007 MB/s
Random Read 137502 IOPS
Random Write 97326 IOPS

What a load of bull. There's clearly some buffer that makes it appear to write fast (60MB/s) for the first ~10 seconds. Then it goes down to 10MB/s. Slower than USB2. Avoiding Sandisk from now on.

This drive has been working great and gets fantastic read speeds. I didn't pay attention to the differences between the models, but make sure you know that the smaller capacity models get slower write speeds than the larger capacity versions. Mine gets exactly 130MB/s write speed, which is what Samsung rates it for. It's certainly not slow, but I was a little surprised to see that number at first (my fault for not researching like I should have). If I were buying again I might do a little more research to see if there's a similarly high quality drive that gets better write speeds from another manufacturer. That said, it's been working wonderfully and my Mac Mini is nice and snappy with the drive installed as the boot drive.

Currently run a 480GB SSD and a 3TB 5400RPM drive, and my 3TB was almost full of Steam games. Wanted to grab a faster/larger drive so I grabbed this guy.

 Unfortunately I didn't get the insane >200MB/s read/writes some people here are getting, but I'm still getting a respectable ~175MB read/write despite being ~50% full.

Was worried about noise from some of the reviews, but it's not noisy. You can hear it if you're listening for it when it's being written/read from, but it's not loud or distracting.

High speed continuous read and write, great for high speed storage use. Relatively low random read/write compare to M4, so I`ll just keep my M4 as system partition
