i want SSD´s for DATA storage (for my photo collection etc.). big SSD´s that doesn´t cost a leg and an arm.
i have a fast M.2 SSD for the OS but i want silent SSD´s with 2-4TB, with good access times. they don´t need to be high performance.
but i want to get rid of vibrating hardrives... i am sick of big 5.25 inch vibe fixers. small 4TB 2.5 inch drives in sharkoon mounting frames.... that´s my dream.
I completely agree. Companies are still trying to release blinding speed sata3 drive when msata blows it out of the water. Most sata3 drives will "feel" the same in daily tasks. I assume the "feel" of sata3 and msata is also very similar, but i havent used an msata drive yet.
Give me a 4TB 2.5" ssd that can maintain at least 125MB/s read and write (enough to saturate 1Gb ethernet). Price at 400USD and I'll buy 4 of them today.
NAND is the largest portion of the BOM, and its cost won't really be any lower no matter how fast the drive is. The only way to decrease NAND cost would be to use low quality dies (like the ones you can find inside cheap USB drives), but then you face serious reliability concerns. And nobody wants to sell a drive they know is unreliable.
And even with lower quality NAND there are hard limits to the currently possible cost reduction. And 2x the capacity always costs (about) twice as much to produce.
Same, except 4-8TB to replace NAS HDD's. 24 HDD's in my NAS. Low power and reliable. Low performance is fine, still going to be way faster than a 5,900RPM HDD.
hopefully performance is good.. But how much on the Bill of Materials is samsung actually saving vs it's MGX controllers to warrant a whole new storage controller.
I have an OEM samsung ssd i got secondhand. Unfortunately it's not supported by samsung magician, so depending on your needs and budget, this may not fit the bill for an affordable ssd. Oem support for the pm830 series was less than ideal i.e. nonexistant. YMMV. I was able to secure erase with parted magic, and performance, while not top tier, is more than acceptable for standard use. However, for me its retail only from now on.
Getting to buy one in 2 hours, my supplier just received the shipment. Price is ridiculous - $65 for one piece , Location Sofia, Europe. Will do some tests soon
Yes, exactly. Usually a few gigabytes dedicated as buffer to deliver MLC type speeds until the buffer runs out, then you're stuck with the slower speeds for larger data transfers.
If RAPID is enabled, the SSD does utilize RAM to achieve ~3.5GB/s, however the data isn't cached on RAM, it's simply using RAM at the block level to achieve the high speed rate of RAM transfers. Think of RAPID as a utilizing RAM as RAM drive, however unlike a RAM drive, the SSD copies data at the block level.
So to answer your question, no, SSDs are not volatile storage mediums and do not lose data when power is cut. Worse case scenario would be one could possibly lose a few file blocks if the SSD was utilizing RAM at the time the power was cut to transfer said blocks, however it's highly unlikely due to the speeds at which RAM transfers information (for example, using RAPID, I've cut and pasted a 3GB WIM image in ~1 - 1.5 seconds).

We need prices! Without a good price they won't be good drives.Flunk - Wednesday, March 23, 2016 - link
Read the article, OEM only.Himrin - Wednesday, March 23, 2016 - link
Yes, because Newegg, TigerDirect, and Fry's Electronics never sell OEM items to individuals...Murloc - Wednesday, March 23, 2016 - link
they can do whatever they want but you're still not going to get a MSRP from Samsung obviouslyhojnikb - Wednesday, March 23, 2016 - link
Hopefully samsung releases 760 drive with this controller for retail aswell :)Arnulf - Thursday, March 24, 2016 - link
Hopefully?! This is a downgrade from 750 EVO series, I'd buy Toshiba if I wanted inferior performance.hansmuff - Wednesday, March 23, 2016 - link
Isn't Samsung migrating the 850 EVO to 48-layer TLC V-NAND?MrSpadge - Wednesday, March 23, 2016 - link
They're starting with the highest capacities, indicating limited supply of the larger dies.Gothmoth - Wednesday, March 23, 2016 - link

4TB for $400? Good luck.redfirebird15 - Thursday, March 24, 2016 - link
One can dream... We are already at 700 for 2TB.JW0914 - Friday, May 6, 2016 - link
The new 48 layer 4TB will cost around $1555, whereas Samsung's new 16TB 2.5" SSD will cost just shy of $11k.redfirebird15 - Wednesday, March 23, 2016 - link
And i think i meant M.2 when i said msata, but my point is still the same. TBH i havent researched M.2 enough to talk intelligently about it.smorebuds - Thursday, March 24, 2016 - link
M.2 is just the interface. You can have M.2 sata and pci-e drives.Kristian Vättö - Thursday, March 24, 2016 - link

You are still using 5.25 inch HD's? YOu should at least move to 3.5" ones, although you probably meant 3.5" not 5.25"rhangman - Thursday, March 24, 2016 - link

Your links are backwards. In the last paragraph, the 750 link goes to the 850 review and the 850 link goes to the 750 announcement.Visual - Monday, March 28, 2016 - link
So what is "TurboWrite" and how does it work? Does it just mask the lack of performance for a while until it runs out of some buffer or something?thespanky1 - Monday, March 28, 2016 - link
Yes, exactly. Usually a few gigabytes dedicated as buffer to deliver MLC type speeds until the buffer runs out, then you're stuck with the slower speeds for larger data transfers.Visual - Tuesday, March 29, 2016 - link
Is it buffered in your RAM, or is it on the device? How does it handle power cuts?JW0914 - Friday, May 6, 2016 - link
