The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
The Heavy test doesn't write enough data to fill a 120GB drive, and when there's still spare area the 750 EVO performs better than any other planar TLC drive. When the test is run on a full drive the 750 EVO suffers more than most and falls to the bottom of the rankings.
The penalty that the 750 EVO pays when filled is even more apparent when looking at average service times, pushing it into last place.
Even when starting on an empty drive, the 750 EVO's latency outlier situation isn't great, beating the ADATA SP550 but little else.
The energy usage of the 750 EVO only stands out for the full drive case. When starting with an empty drive, the 750 EVO uses less energy overall than the other planar TLC drives.

Isn't that the truth! Nearly every item comes with glowing reviews mixed in with "mine died in xx time, and I am never going to buy from $company ever again." Consumer routers and hard drives seem particularly bad in that way-- if I avoided all of the ones with horror stories, I'd never have either of them.Another thing people tend to overlook in reliability is the role of a good power supply. A cheap PSU can slowly sap the life from all the components in the system by introducing unacceptable levels of ripple, and you'd never know that was a cause or partial cause of the failure. On a laptop with the brick-style power supply, it is a good idea to replace a failed unit with an OEM unit of recent manufacture (less chance of dried-up caps) than some eBay special of unknown origin (other than to say China, which is where the OEM one came from too, almost certainly).
For desktops, the PSU is something people sometimes skimp on. I've never actually had a prebuilt desktop, but I would bet a lot of them have cheap PSUs, as it is probably a place where pennies can be pinched without a huge increase in RMAs before the warranty expires. I looked at new PCs on the site of one of the major online sellers about a year ago, and I was surprised at how many current models still had 120/240v switches on the PSU, which shows that they are older models without active PFC. That does not necessarily mean they're of poor quality, but it does make me wonder about them.

I think it needs to come down in price before it'll be an acceptable sort of purchase.zepi - Friday, April 22, 2016 - link
SSD's have lost a lot by being so hamstrung by their interfaces. CPU's have limited number of PCI-e connections and motherboards very little space for M.2 slots. SATA 3 is slow and bad protocol for SSD so that race to the bottom is only thing that is of any interest in 2.5" drives.TheinsanegamerN - Friday, April 22, 2016 - link
SATA 3 may not be super fast, but the only observable difference, IME, between an m.2 drive and a sata drive was 2 seconds on boot. Unless you are a content creator working with laarge video/pictures, m.2 has little to offer over sata.Especially given that 2TB sata ssds exist, while m.2 is limited to 512GB, and that 512GB m.2 is more expensive than a 1TB sata ssd. And the ehat that m.2 drives give off compared to sata.

It may be "cheap", but it's worthless in my opinion. Only 120GB or 250GB, pretty much too small for anything except a boot drive. If there are no 1TB drives, why bother?TheinsanegamerN - Friday, April 22, 2016 - link
Believe it or not, many people could fit their computer needs in 250GB.I only use about 500GB between all of the games I actually play, and the OS itself.

Mmmm, I think a lot of people have digital media collections now. I have no DVDs or Blu Rays, but 600 GB of films and TV series.barleyguy - Friday, April 22, 2016 - link
Video doesn't need SSD levels of performance. Any modern spinning disk is fast enough to play video, even up to 4K.Personally, my video server machine is a 250 GB MX200 M-SATA SSD and a 4 TB hard drive.

Absolutely but I want a single high-performance disc.Bleakwise - Sunday, April 24, 2016 - link
Why do you want an SSD for cold storage backups? That's just silly.
