s the speed advertised (280MB/sec read, 180MB/sec write) the sustained read/write rate, or is this a burstable rate that drops after a few seconds?

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

You are correct (and previous answer is not). The drive interface is 6Gb/sec (that's gigabits per second), as it says on the label. This is the standard speed of Sata3. This translates to roughly 600MB/sec - plenty enough to carry the quoted 550 MB/ sec the drive is capable of.

These drives are kind of strange. It transfers off the drive at high speed (~20 MByte/sec) but only writes at ~2 MByte. So I think it's USB 2.0 but the internal flash management chip on the drive must be pretty inefficient so it can't keep up with the comm. speed when it's doing write operations. Delete operations are also really slow. So overall I probably wouldn't recommend this product. I got them because they were cheap and I don't need high performance for what I'm using them for.

I'm sorry I do not know, nor can I find any reference to its speed. I use thunderbolt to run my drive and it sizzles.

The main thing is this: when I bought my 3000 dollar laptop from HP, it came with 128gb msata card for drive c. I wanted to ugrade to 256 from bullet. I was surprised like many are that their laptop was given a sataII msata and I got 225 read and 175 write. After using the Bullet case I cloned my c drive and my read speed went up to 550 read and 420 write. Now because of the nature of the beast the USB3 port only gives you sataII like speeds. which is still faster than a spinning hard drive. I use ATTO Disk Benchmark Speed test software. It is a free download, google it.

I can check later when I take it offline. Right now the green disk access light is flashing rapidly indicating a lot of disk activity. In other words, it is currently recording some TV via my Snapstream / Beyond TV recording software. I'll get back to this maybe next week. I do know that it is 7200 RPM.

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.

MLC or TLC NAND question has been answered. But, I just wanted to clear up something that made it confusing to me when purchasing the 64gb. Amazon has the description for the 64gb as "Up to 90MB/s Read Speed, 50MB/s write speed". The samsung packaging I received clearly shows "read speeds up to 90MB/s, Write Speeds up to 80MB/s". Glad this is up par with the speedy 32gb version. Hope this helps.

heh Understood, and much more comforting to know you ran and it passed, three tests. >__>b I'm definitely interested, as this is a great deal for 16GB. Thanks for the quick response!

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.

Reads @ 19.5 Mb/s. Have not performed write test. Mostly use it for RasPi OS. Works well enough for that. Hope this helps.

Something is not right there. On a wired 1Gbps connection with a single copy I would expect at least 400Mbps, with speeds over 700Mbps on faster switches (efficient internal packet forwarding). That is from testing when I first received the unit (tested with 4 x 5200 RPM Toshiba 160GB in RAID 5, prior to 4 x 7200 RPM Seagate 750GB in SHR I have had in it since then - but I haven't tried that on a fast switch, my home switch seems to max about 500Mbps). For comparison, I've seen speeds close to single line speed (~900Mbps) on a DS713+/DX513 combo. If you are on WiFi, I would run hardwired tests for comparison. Then start troubleshooting your WiFi.

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.

Hey Gov, based on my testing of the card, read and write speeds of 44.4MB/s and 19.1MB/s respectively. Hope that helps.

No its 480mbps high speed 2.0. I like it as its easy to install and works with windows 7 and I have 3.0 on my motherboard and to tell the truth I copied several files from the computer hard drive to a external hard drive and several were over 1 GB and I could not see much difference in speed and the external drive is a USB 3.0. That card does everything I wanted it to do and I have no complaints, its worth the money.

I cannot say I did benchmarks but I did monitor backups to it. I saw speeds between 40 - 58 MB/s in large networks and in the 60s in home networks. Both on Gigabit speeds.
