Pros: Still one of the fastest 128GB SSDs on the market today.
Sequential read speeds top out at about 530 to 540 MB/s.
Sequential write speeds top out at 370 to 380 MB/s.
Smaller 128 GB SSDs have less channels in use as opposed to their 256 GB and 512 GB counter parts. Thus their write speeds top out at lower speeds.
5 year warranty.
These Samsung SSDs are unaffected by whether the data is compressible or not.
This SSD is installed on a laptop and it is the only storage device. Even so it is wearing at a more than acceptable rate. Thus far it has written about 1TB and the wear indicator is at 14 (maximum number of writes to the NAND blocks). Per those numbers, I estimate the SSD should be good for about 214,285 GB before it reaches the 3000 maximum P/E cycles (give or take a few GB).
Other Thoughts: I bought the Samsung 840 Pro SSD for my wife's Sony Vaio laptop. Installation was as easy as taking the HDD cover off the laptop, pulling the mechanical SSD out and installing the 840 Pro in. That's it (well, had to install the OS afterwards of course).
The laptop was already fast (i7 Sandybridge and 8GB of RAM), but this SSD takes it to an entirely new level. Consider that many laptops come equipped with slower 5400 RPM drives.
Yes, 128 GB is not much by today's standards. However, we have a home file and media server were we keep all of our files, so the laptop's SSD only has to have enough space for OS, Programs and caching.
After almost a year of envying this SSD's speed, I bought two Samsungs 840 Pro 256 GB and installed them on my work and gaming rig. I'm getting over 1 GB/s read and write speeds! (core i7-4770K on Gigabyte Z87X-UD5H mobo).
This review is from: APEVIA CVTUSBE25 11" USB Extension Cable for a standard USB motherboard connector
Pros: Does what it is supposed to do.
I have an internal USB card reader mounted on a Xigmatek Elysium super tower. The USB cable on the reader is not long enough to reach the motherboard's header.
The extension provides the needed extra length to reach it.
Cons: None.READ FULL REVIEW
This review is from: Rosewill RDCR-11003 74-in-1 USB3.0 3.5" Internal Card Reader w/USB Port
Pros: USB 3.0 speeds. Please note that the effective speed will depend on the memory card or USB stick you plug into it.
Easy installation on 3 1/2 inch external bay.
Plugs directly onto motherboard's USB 3.0 header (no need for adapter).
Cons: It has a blue LED indicator which tells you whether it is connected as a USB 3.0 device. It is supposed to indicate power to the device. But I've found that sometimes it will not be lit and the reader still works... but it defaults to USB 2.0 speeds. Windows gives me a little message that my device could perform faster if it was connected to a USB 3.0 jack. Well, itis connected to an internal USB 3.0 header.
I had a Rosewill USB 2.0 card reader very similar to this one. It had the exact same problem. That card reader was connected to an internal USB 2.0 header of a different motherboard. Sometimes the power light would go out, but the reader would still work... but at USB 1.1 speeds.
Other Thoughts: Even though the con listed above is annoying, a reboot fixes the problem.
I don't use it much, I kinda just have it for those rare instances when I have to plug in a flash card of one type or another. I haven't been bothered enough to look for a solution or replace the reader.
When I do use it, and it is working as a USB 3.0 device... it is fast!
