The PNY CS1311 and CS2211 SSD Review: MLC vs TLC at 15nm
by Billy Tallis on April 15, 2016 8:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
The average data rates on the Light test don't show a clear separation between MLC and TLC drives; only a handful of drives stand out with particularly low performance, mostly due to being small TLC drives. Full drive performance reveals more interesting differences than the empty drive performance. The CS2211 pays one of the largest full-drive penalties among MLC drives. In the TLC segment, the OCZ Trion 150 holds that distinction, but it starts with high enough performance when empty that it generally remains faster than the CS1311.
The CS2211 again has the slowest average service times of all MLC drives, but with only a moderate gap between it and the others. The CS1311 is roughly tied with the ADATA SP550 and slower than the Trion 150.
The rankings of the PNY drives going by latency outliers are similar to the rankings for average service time. None of the drives are truly overwhelmed by the Light test, but the smaller capacities of the CS1311 do suffer significantly from a full drive.
The power consumption over the course of the Light test does little to distinguish any of the drives. On light workloads, the idle power will matter more than the figures reported here. That said, it is interesting that the 240GB CS2211 comes out slightly ahead despite being slower than the 480GB CS2211. The smaller 4-channel S10 controller may be saving a bit of power over the full size.

How is that not good enough? That's 3 years if you rewrite the ENTIRE drive EVERY DAY.Let's pick a long 9 year planned lifetime for a drive as you would probably want to upgrade by then for non-failure reasons. That means you could write 1/3 of the drive's capacity every day for those nine days. For a 256GB drive (somewhat on the small end now) that's 85GB every day. Or installing 2-3 AAA games every day!

Well, on a modern OS you no longer control the amount of data being written. Automatic updates, indexing, metadata, restore points... the OS will write those whenever it wants to.If planar TLC was half the cost of MLC or V-NAND TLC, I may consider it. But since it's within 10-20%, I'd rather get the better drive.

The average laptop user writes 10-20gb a day. Even if you were double average you would still be safe as houses.BrokenCrayons - Thursday, April 21, 2016 - link
I have a modern OS on my laptop and have quite a bit of control over what does or doesn't get written to storage. For instance, there are no restore points, indexing is mine to manage as I see fit. I can pick when and what I want to update, and I haven't allocated a partition to swap (thank you Linux). You just have to exercise a bit of selectivity about which modern OS you decide to install.rarson - Monday, April 18, 2016 - link
In my experience, the average mechanical hard drive has a life of about 2 years. I see many of them fail before then, and most of the drives these that last over 5 years are already 8+ years old.I recently bought one of Seagate's 8TB archival drives and it started making some clicking noises right out of the box. It hasn't given me any problems yet, but it is a bit disconcerting to hear a click every couple minutes. Hard drives just don't last very long anymore, while my SSDs have been rock solid with everyday use. I would not install my operating system on a mechanical drive ever again. No reason to do so.

i put windows XP on this 1311, and it's the fastest I've ever seen XP do anything, startup, tasks, and installing software and launching programs, faster than high end workstation systems on HDD's, since it's debut in 2001... loland yes, the XP OS is extremely stable because the 1311 takes care of garbage collection in the background.
burn tested it for several hours and days on end, it's perfect...

I can't imagine buying any PNY products in any event, but even more so given that the Samsung EVO is so much more bang and reliability for your buck.DigitalFreak - Friday, April 15, 2016 - link
Every PNY device I've had, whether SD cards or video cards, has died prematurely. Absolute garbage.The_Assimilator - Friday, April 15, 2016 - link

My pny 770s are going strong 2.5 years later. Also some of the coolest running 770s I've seen
