Hama Solid State Flash Drives: 2.5” SLC & MLC 32 GB
Hama also offers two 2.5” flash SSDs, which fit very well into the line of drives we already tested. There is one high-speed version based on SLC flash memory, and a lower-cost mainstream model based on multi-level cell flash. The differences are tremendous, as we mentioned earlier.
Hama Highspeed Solid State Disk Flash 32 GB 2.5” SATA
The faster of the two 2.5” Hama flash SSDs reaches more than 100 MB/s read throughput and 83 MB/s writes. This is backed up by our streaming throughput test, where this drive delivers great performance and still good performance per watt, although the flash SSDs by OCZ and Samsung are the clear winners in this category. Hama’s high-speed 2.5” drive does well with 0.8 W idle and 1.8 W peak power, but this isn’t enough to outperform the best of the class in terms of performance per watt.
We also found the I/O performance of this drive to be exceptionally quick: Hama’s Highspeed Solid State Disk Flash 32 GB 2.5” SATA was one of the fastest flash SSDs in our workstation I/O test. It delivered hundreds of input/output operations per seconds in the database and fileserver tests and was even the second fastest after Mtron’s 7500 Pro drive when it comes to web server I/O performance, where no writes are involved.
Hama Solid State Disk Flash 32 GB 2.5” SATA
The second option is much cheaper, but it does not get near the 103/83 MB/s read/write throughput. Instead, it’s limited to 62/29 MB/s. This can be found both when looking at the interface throughput as well as the read and write transfer performance results. The other performance numbers aren’t very impressive either, as the high-speed version can be many times faster. We also found the average access time to be five times longer on this drive than on the high-speed model. Although 0.5 ms to 0.1 ms is minimal compared to 5-20 ms for conventional drives, the difference is significant.
One might believe that the slower drive would at least be more efficient, but that’s not the case either. The regular Hama Solid State Disk Flash 32 GB 2.5” drive requires 1.9 W of idle power and up to 2.7 W peak power. Compared to 0.3 W idle and 0.8 W peak power of the much faster OCZ and Samsung flash SSDs, or many others at 0.8 to 1.2 W idle and 1.8 to 2.2 W peak, the results are almost embarrassing for this product. The only serious reason for getting one of these “regular” Hama drives would be mechanical robustness or a great bargain, and we doubt the latter will happen any time soon.

So why wasn't OCZ's new Core Series SSD included in the testing? That's the SSD I want to see the benchmarks and power requirements on.
Sorry, but this review is worthless withous OCZ Core SSD.

You've got that right.
Why wasn't the VelociRaptor shown also for comparison????
I would be stunned if the Core could match the Samsung and other high performers in this test. All indications I've seen are that it is MLC, which is significantly slower than the SLC used in the Samsung and all higher end SSDs. That's why the core is so cheap.
Of course, I haven't seen any tests, so I could be proven wrong, but I doubt it.
Well, nothing new here.
A comparison of random write access time would have been very nice
since this a major disadvantage of SSD (as far as I know).
Some flash drives reach less than 10 IOPS when writing small random files,
which means >100ms access time!
Harddrive charts, like the CPU and GPU charts will be very helpful. Start compiling all the data now Toms and keep them up-to-date.
I will completely agree with THG's findings. I purchased the Samsung’s 64 GB SSD SATA-2 from Newegg many months ago (in the $800 price range). I gave the drive a top-notch review at Newegg back then and would do so again in a heartbeat. It is truly amazing how much the HD can bottleneck a system until you get a drive like this. Anyone who has a need for uncompromised speed with the appropriate budget has to look no further than these two products recommended by THG.
the core is already outdated... please include the OCZ core v2 SSD guys.
...throughput. Silicon Power actually ships capacities of up to 128 MB, but its performance disappointed. The... should be 128 GB
what about the fusionIO drive? does it live up to its incredible claims? 600MB/s write and read?? http://www.fusionio.com/
please please have a look and this drive!!
@ fredsky...
Agreed!
WTF, I just bought the new OCZ Core v2 from neweeg for under 250 with tax (hate NY!) and shipping after a 40 dollar rebate. It's MLC but shows huge speeds for read and write. Like 153/93 !!! I was really hoping to read about it here, but alas there is nothing.
Also no prices??? Thats stupid.
Also ridata has a new SSD thats right up there with the new OCZ which I would also like to see reviewed, however because it had no warranty listed, (the OCZ has 2 Years!) it didn't get any $$ from me.
Dumba$$es.
I just bought the new OCZ Core v2 from neweeg
Newegg is only selling the OCZ core version 1's. They don't have version 2s... Are you sure you bought a version2?
This is a version 2 model number -> OCZSSD2-2C30G
This is a version 1 model number -> OCZSSD2-1C32G
I have one of the Silicon Power 32Gb MLC units - they get about double the speed of the 128mb version Toms has tested and in our market, they cost about 1/2 the price of the OCZ-branded.
PCM05
Startup 27.09 vs 3 here
Write 66.80 vs 38 here
and the HD Tune results:
Transfer Rate Minimum : 86.4 MB/sec
Transfer Rate Maximum : 117.4 MB/sec
Transfer Rate Average : 106.8 MB/sec
Access Time : 0.4 ms
Burst Rate : 51.0 MB/sec
CPU Usage : 4.4%
Makes me wonder if there's something else here, maybe they had an old version or something.
If they can produce a 128GB unit for around $200, I would take the plunge.
We didn't get the initial Core drive for review. V2 will be included next time.

I don't know about the pricing of the drives,
but for a replacement drive I'd go with the HAMA Highspeed flash 3,5", due to it's reasonable fast speeds, and reasonable powerconsumption.
The only reason I'd suggest staying away from OCZ for a while is their drives high defect rate. To allready have a complaint the day the drive gets released, and have several complaints about broken drives the first 4 weeks of production leaves me no good impression. I probably not go for OCS the first year or so; despite their low pricing.
I yet have to see the HAMA price before I decide to buy any. A price chart would be nice indeed.
Also, looking from notebook perspective would be more interesting, since the majority of SSD's are bought for powersaving, shock resistance, and data reliability; not speed as what most people would think.
Ups for including a boot time simulation chart! That 'd replace the random read table other users have been asking for.
A minor remark: SSD's and laptop HD's are most of the time idle. I would put more stress on the idle powerconsumption, then on peak power; except for MLC drives used for data storage/read.
edit on prev. post:
Companies wanting speed (meaning the higher performance range like Memoright) probably would rather go for raid SCSI HD drives or similar.
From notebook point of view:
MLC is too slow for OS, and preferrably is used for extending data storage.
Allthough anyone running 2 SSD drives (1xSSD SLC, 1xSSD MLC) might consider if running 1 HDD wouldn't use less power.
The perfect solution fornotebookusers wanting to replace their HD would be a 24GB SSD SLC for the OS with additional MLC flash for data storage in one drive, with good powersaving options the OSC drives deliver.
