What is the read/write speed?
888330
I don't know the exact speeds, but it's one of the slower drives I have. I have the 8GB version and I don't recommend it.

It will only write at a slower speed, due to it not being USB 3.0, but it works well. If you only have USB 2.0 port, then this is a good Stick, I own several. Plus I installed a USB 3.0 in my PC, a good upgrade for less then $30. easiest way to calc speed and look at an ad, for USB 3.0, it will say how much faster then USB 2.0

It appears that the Writing speed is about 5.60 MByte/s and the reading Speed is about 7.37 MByte/s. This is based on some of the tests I was able to run on my PNY Attache III 16 GB USB 2.0.

Ah! Cache, great, thank you for sharing this. I wonder if there's any noticeable read or write speed difference between 16 and 32 -- I was under the impression that 16 was quite a bit. Thanks again!

This device is a writer, not a reader. If you are intending to read (as in, watch) BluRays, this isn't the device for you. If, however, what you intend to do is backup your data files to BluRay format, you want this. I cannot provide the actual write speed data for this device, but on USB 3, my experience is that it is fairly fast, determined of course by the amount and type of data you are writing.

SpeedOut_0.5 This little free app will tell you. I used it with this usb 3 express card, and a PNY 128 gig usb 3 flash drive. I only got read speeds of about 70 MB/s and average 45 MB/s, the external power to USB must be plugged in to get this transfer rate (or you get worse than usb 2 transfer rates). In comparison on the same dell E6500 the same usb flash drive gives 25 MB/s read 15MB/s write. So my Renesas uPD720202 based express card is only 3 times faster than usb 2. I am trying to find drivers that might improve this. I understand that this my not be the card itself but the bottleneck may be the nature and version of the expresscard slot on my machine.

Well, I have a test tool, that shows 233.7MB/s write and 319.0MB/s read with a SSD drive in an USB 3 enclosure via an iogear USB3 hub.Most USB sticks, or SD cards are way slower than this.The USB3 hub disconnects, when Yosemite goes to sleep. Then via eSata it copies 1.4GB in less than 5s to my backup drive, not sure, if my drive is a bottleneck, but I am happy with the speeds.

Sandisk is remarkably bad for info. I know that the Titanium series is faster than the regular Micro, coming in at 15MB/s read speed & 9MB/s write speed. I seem to recall that the Micro is closer to 10MB read and 6MB write.

From: PC: Intel Core2 CPU 6600 @ 2.4GHz (Windows 7, 64-bit) Port: USB 2.0 Card Reader/Writer: Kingston's MobileLite G3 To: SanDisk Extreme Pro 16 gb And an IMG file (2,478,505,984 bytes) I can reach 27 mb/second Note 1: maybe with a USB 3.0 port you can reach a best speed. Note 2: maybe without an adapter you can reach a best speed.

An easy way to test that out is to have a 3.0 flash drive and transfer a 2-4gig file (a movie works nicely) and compare the speed. The 3.0 is noticeably faster. I found that the instructions that came with my laptop were not reliable in that regard. I hope this of some help to you.

Using a Crucial 512gb mSATA is am getting ~450MB/s+ Write and over 500MB/s read. This is on a late 2013 rMBP. Tests were done with BlackMajic Dist Speed test in OSX. In bootcamp with CDM I am getting about the same numbers. Yes it is getting very very hot! Not sure what to make of that either. Seems to work fine.

Ok so there's a few things you need to understand in relation to comparing speeds. First there's no standard read write speeds for hdds my 7200 3tb drive ranges from 72 to 150 MB/s Next plastered drives are hard to compare directly with solid state. Platter drives read faster on the inner tracks compared to the litter tracks. There's also spin - up and spin down time for a platter drive. Now this ssd WILL max out your 3gbs sata2 at about 300 to 380MB/s Of course you look and see oh that's only double. True long read will be about double speed. However, it's those short access small files that'll benefit the most. Ssds have no platter. So no spin speed. They just send as much as the device / interface can handle. They also don't "seek" for data so there's no time loss there. In random reads my ssd is roughly 60x faster over all. But if I'm moving a TB of movies or whatnot. It's not AS remarkably fast but still a 100% better experience.

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

I am using an older desktop computer and with a USB 3.0 card installed into my computer. Testing speed using HD Tune Pro and a 2GB file I get a write speed 105 MB/s and a read speed of 130MB/s. You will never get maximum stated speed as this is faster than a mechanical Hard Drive you would need a SSD Drive for maximum speed. I purchased the 64GB Version late 2013 and use every day and never had a problem and love the speed.

mine is around 44k read and between 16k and 20k write. The 8mb meaning you can potentially take 360 8mb photos per minute.

The maximum theoretical throughput of Tbolt is 10GBps. The overall speed of the reader depends on the device being read at USB3 or sata and that depends on the card.

Sequential Write speed for the 128Gb is 150MB/s if i remember correctly.Sequential Write speed for the 256Gb is 300MB/s.Sequential Write speed for the 512Gb is 500MB/s.They all have the same Sequential Read speed of 550MB/s.

Hi, I got this in February from Amazon and I have been very happy with the performance of the Corsair 256 GB model I recieved. I did some real world transfers using a stop watch and a 5.23 GB file transferred from my internal SSD to the Corsair in about 26.7 seconds. A smaller file at 2.26 GB transferred in about 11.6 (remember I am pressing the button) so both clock in at about 200 MB/Sec writes. I downloaded and tested it with BlackMagic disk speed test and it consistently 170 write and 290 read speeds and Blackmagic says it would support writing at 1080p24 at 10 bit YUV 4:2:2 (whatever that means). I have even run a couple of VM's on it with VMware with acceptable performance. Hope this helps

As I understand it that the maximum speed of the Interface between the computer and the device. Since the device is basically all Solid State electronics, as opposed to a traditional spinning rust HD, the 6gb/sec is actually closed to a true read/write speed than you might imagine. note that that's 6gb ie BITS not BYTES... IE 8 b's per byte plus handshaking overhead but is a still twice that of tradition SATA which is only 3gb/sec max.
