Seagate ST2000DX001 2TB Hybrid SSHD

17 posts in this topic

Hi,

I am thinking to buy this drive and I need your advices to decide. I know this driver is not even close to SSD performance but I need space in addition to speed so I want to ask if this drive cache files from reptitive tasks fast then it whould be good choice for me because I switch between many apps and games per day but if this drive need long time to learn what files to cache then I would rather get 3TB or 4TB drive. please advise.

Thanks

Do you have $80-100 to spend on an SSD in addition to bulk storage? What drive do you have now?

You'll be much better off with a small SSD of, say 64GB and a regular 2TB drive. The tiny cache on the 2TB drive is just too small to really be useful.

You can either configure the SSD as a cache (see Sandisk ReadyCache), or just install OS + apps on the SSD and keep media on HDD.

Yes I see your point guys. I have now Samsung 830 256 + WD Black 1TB + Seagate 7200 1TB with my current motherboard that support SATA II only. OS and apps in the SSD but I did not like the speed of opening my apps and games while setting windows cache to 1GB, now I tried to make it 16GB and I found apps that take 12 seconds now take 3~4 seconds this is really good!! so I am with you to invest in SSD.

In fact I am ready now to get another SSD 256GB with my current one OR I get 480GB/512GB and sell my current one ? later I can buy mechanical HDD.

Another question I see now in Amazon 3 hot products Samsung Pro, SanDisk Extreme II and Crucial M500 which to get ?

The M500 has excellent prices now in fact if I paid a little more than Samsung Pro and Extreme II 512GB I can get Crucial M500 960GB !!. Please also consider to advise me with a drive has the lowest RMA rate because this drive will be shipped overseas, RMA will be very difficult and costly.

Appreciate your help.

I don't think you'll find much market for a used SSD, I wouldn't buy one, but maybe you can...I just don't know.

As to what to buy, depends on your budget, I'd probably lean toward the Samsung EVO for best of both worlds.

SR Admin,

SSD are rare in my area and if exists are old models with 2x the price!!

What do you think of M500 ? it is MLC but is it noticeable slow ?

I've bought quite a few used SSDs, they're good for test systems, HTPCs, etc. I won't pay a lot for them though - roughly half of what a similar new one would go for. Heck I even bought a used one just for use as a scratch disk, because I couldn't bring myself to buy a new one just to write to it non-stop and wear out :-P

I second the Samsung recommendation. For what I consider my "critical" systems, I only use Samsung. I've used plenty of SanDisk SSDs, both new and used, in other systems with no problems, however.

Personally I'd repurpose the old into another system, or sell it, and get one larger one. Some people opt to stripe multiple smaller ones, but I don't bother.

Crucial M500 is the slowest of the three SSDs you listed. The Samsung 840 EVO and Sandisk Extreme II appear to be the two to get today (the former for value, the latter for performance), although the Samsung 840 Pro and quite a few others are very, very close to the Sandisk Extreme II in performance (the gap is within measurement margin of error, it's that close) in many cases.

@Mod

I see. I would get the EVO but I like the M500 power failure safe feature, I get frequent power loose and sometimes my UPS does not keep up. In fact I dont worry about loosing unsaved work but about SSD die of frequent power loose ?

SSD's rarely die but they may corrupt data (HDD's run a similar risk).

If your UPS isn't working, well, get a better one. ;) (or yes, a SSD with internal power capacitors might help too...)

If the system in question is a "critical" system with which data loss from power outage is generally unacceptable, nothing is better than a dual-conversion true online UPS :-) Personally, I like the Emerson/Liebert units:

UPS is a very good investment, APC had some small 550VA units on sale for like $40 a few months ago. I picked up a few not knowing where I'd use them but knowing better to have than not. Put on one my wireless router and modem, so at least when the power goes out we have Internet for a while, runs for at least an hour. Another on the NAS...they start to go pretty quickly.

Thanks guys, I have the infosec 1000VA it is expensive here and still does not give me good time while gaming, you know because of the GPU.

1000va is quite small for a gaming rig, as you've found. I'd aim for 2000va, and then if necessary an external battery cabinet to extend runtime. I did just that for my NAS, with enough batteries to keep it going for 2 hours. Once thing I've learned is power cycles and by extension temperature cycles kill mechanical drives faster than anything else. So I went extreme on battery backup. And I have a generator at the ready. An oversized UPS will be more efficient and run a lot longer than a smaller one near its limit.

I realize that this is overkill for most folks :-)

Also it may be cheaper to buy two UPS's (one for monitor, one for computer) than one big one. If you are borderline your existing UPS where removing the 50W of load of the monitor will make it work, then a second cheap UPS may be better than trying to buy an extremely expensive larger one.

Many thanks for all the great ideas. My monitor has 33 watt however I am thinking in the future to sell my current UPS and get more capable one.
