Are these goods SSDs?

I'm looking at some Samsung OEM SSDs on eBay, this one in particular.

NEW Samsung 1.8 microsata 128GB SSD Trim Lenovo Dell | eBay

The price seems decent, but I can not find any information about it. Model MZUPA128HMCD-000D1
I see lots of MMCRE drives on eBay and there are some benchmarks that seem like they're decent, but nothing about this drive.

Does anyone know about it? Is it fast? How old is this model?

 

They're probably reliable but if these specs are right they are quite slow.

Maximum Sequential Read Rate: 90MB/s
Maximum Sequential Write Rate: 70MB/s

The problem is the speed as stated above, and I'm not sure what controller it uses which might be another problem. Do you have to go with a 1.8"?

 

if you have to go with 1.8" then it will be comparable fast to any previous hdd you had in there (1.8" hdds are terribly slow). still, there are faster options.

this one is in a similar price ratio and should perform faster (but it's not new).

it all depends, but it sure is a fine drive.

 

I've been using these early MLC Samsungs pretty much since they came out. They're nominally pretty slow, but way faster than a conventional HDD, and I honestly couldn't tell the difference between these and an X25-M G1.

Hence I'm still running three. One has been powered on for almost two years straight.

 

Yeah real world performance of Samsung drives tends to be very good, even when specs are low.

 

Unfortunately I need 1.8". I have an HP 2740p. I don't want to spend much more than that, too, so I'm pretty limited on options as I need at least 120GB.
It's very annoying as if you remove the bottom cover, you can tell if they rearranged some parts in there they could have gotten a 2.5" in. I'd be fine with a 7200RPM 2.5", but this 5400RPM 1.8" drive is killing me!

If the sequential is only that much, then the random speed is even less, yes?

Maybe it's not time for me to get an SSD yet. This computer isn't my main, but I really wanted to upgrade it because it's hard drive is incredibly slow!

 

Just because sequential isn't slow, random is most likely much faster than any hdd. Not to mention access times.

 

no, go ssd, it's a HUGE improvement. but wait for that particular one. where do you live? i might check up if i have a same samsung 128gb ssd still around? i think it's at a friends home, but not used much.

 

If this listing is accurate they show more specs:

Google Translate (click the "view details here" at lower left to get the specs)

Random Read: 70 MB/s
Random Write: 20 MB/s
4k sequential IOPS: 7700
avg access time: 0.13 ms

 

For this class of machine, would performance(in particular sequential) be a major concern ? I think the no moving part, fast boot, low idle power(thus longer battery life) may be more important as these are typical 'grab and go' type device, i.e. more like tablet style usage.

 

performance is a major conzern, but on a wastly different level. 1.8" hdds are TERRIBLE. i remember mine booting up in 5 minutes (with all sorts of optimisations, vista back then), and started up firefox in one minute. getting an ssd (mtron back then, 80MB/s read, 60MB/s write i think) changed this to 30sec boot and 2sec firefox startup.

so performance matters, massively. but at a different level. and the samsung is great for that little lovely tablet.

 

1.8" are bad but not 5 minutes to boot bad. My tablet takes maybe 2 minutes, but I think less to boot. Firefox starts in maybe 5-10 seconds. I still would like to get an SSD, though. I'm not sure I can justify much more than $160 though.

 

back then they where 4200rpm now you can get 5400rpm ones. and yes, vista pre sp1 on a 4200rpm 100gb drive == 5min, no matter what (if you did not want to criple it down to unusable but "very fast booting" os mess. as i actually use my os, not possible ).

had to use it like that for about 3 months, was a really annoying time.

 

I benchmarked my 1.8" HDD

Sequential Read 33.86MB/s
Sequential Write 35.78MB/s
512K Read 16.77MB/s
512K Write 17.80MB/s
4K Read .259MB/s
4K Write .652MB/s
4K QD32 Read .467MB/s
4K QD32 Write .647MB/s

My sequential write is faster...
Why don't they advertise the random read speeds? They might be very bad...
I don't want to drop $170 on an SSD which barely improves my speed and halves my storage. Are there any options other than these Samsung SSDs and the Intel ones?

Benchmark http://forum.notebookreview.com/6597632-post6295.html
4K Read is 57 times faster than my drive. I think I'll see a nice improvement.

 

Didn't you see my post here?

I did, but those benchmarks are for the other drive I was looking at MZUPA128HMCD. I misread and thought those numbers were sequential. They're too high to be real random speeds.

The one I ordered is MMCRE28G8MXP and it's benchmarks are much better for sequential and I can find random read and write benchmarks. I don't believe the site you found as that is way too fast for a drive this cheap, and there are no benchmarks available.

For MMCRE28G8MXP I can find benchmarks and there is a way to flash it with generic firmware and enable TRIM, so I think it's a much better decision. It's $10 cheaper, too!
