In the description, it says "Sequential Write: 300/500MB/s - Sequential Read: 550MB/s". What does "300/500MB/s" mean? Is it a typo?

Hi J. Chen. The 300/500 MB/s refers to the write speed for the different capacities. The write speed is different for the 128GB, 256GB, and 500GB drives. The 512GB drive has the 500MB/s write speed.

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.

read the factory data sheet, read that and see true spec, full performance. do you need a link to CruciaL.

The Write speed was between 9.83 MB/s and 14.43 MB/sThe Read speed was between 64 MB/s and 78 MB/sI have the 16 gb and I used usbflashspeed for benchmark

This card has been working well with my system running 32-bit XP Pro. However, I experience VERY low RAID-5 data transfer rate, about only 40 MBytes/s on read and 10 MBytes/s on write. It should say SATA I (not II).

Do NOT buy the Sandisk Class 2 card! "Class-2" means its write speed is 2MB/S minimum. This Transcend 8GB is a "Class 6" card, which means its write speed is at least 6MB/S. My own benchmark showed that the speed is actually closer to 10MB/S.If you must get a Sandisk card, get either the "Ultra II" (which is similar in speed with this Transcend card) or the "Extreme III" (which is the fastest)

My benchmark using CrystalDiskMark shows its sequential write speed is 12MB/s. That means it meets class-10 requirement.

A regular harddrive reads and writes about about 80 megs per second, this drive does it at around 400 mps. Its really impressive, but you need to make sure both the drive and the computer its connected to have SSDs and thunderbolt to take advantage of the speed.

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.

Appreciate the feedback. What does 30mb per second read mean? Is that from the disk to camera? Or camera to PC? And if I do go lower what will i lose out on? i.e. what potential wil lbe untapped? Sorry...newbie here and appreciate your help.

I do not recall. I do not think the rotational speed of the drive would explain such incredibly slow transfer rates I was getting about 10 MB per hour.

I wrote a non-techie review of my 64g and 128g. I compared writing 37.3 gig of data - the San Disk disk took 5:55 minutes for the 64g and 5:50 for the 128g. The other 2 (not cheapies) took between 25 and 36 minites. All were done with the same source data on the same computer using the same USB3 port. They were all USB 3 drives. Not sure what the specs are, SanDisk has them on their website, but I can tell you it is faster than any of the others out there except maybe the Lexar and the price on those is much higher.

i din not really know the write speed but it is faster than circular seek swite disk. i am happy with it.

Read is up to 500MB/s and write up to 400MB/s. Bootable as an OS disk or use it as storage drive. Can be use with PCI-e adapter card.

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!

Markus Twain,There is no attempt to mislead customers. The 1GB reference in the lower section is a typo, which will be corrected, nothing more. Thank you for bringing it to our attention!

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.

I have a used this drive with a 64 GB card and 128GB there has been no trouble with it being read and the speed is the same as the 32 GB cards I have used with the Transcend Information USB 3.0. Hope this helps out.
