Hitachi increases reliability with 3TB enterprise-class drive
TechSpot

Spoiler

tsitaat:

Hitachi has introduced a new member to its Ultrastar series of enterprise-class hard drives, one that the company claims will deliver greater reliability and save on energy costs at the same time. The Ultrastar 7K3000 is available in 2TB or 3TB variants featuring a 6.0 Gbps SATA or SAS (Serial Attached SCSI) interface. It comes with a 7,200RPM spindle speed, 64MB of cache and a power consumption of 5.6W or 6.6W while idling for the SATA or SAS versions, respectively. Like its predecessor -- the 3.5-inch A7K2000 -- the new drive has five platters, but it increases the areal density on those disks by 50% from 400GB per platter to 600GB. This means that datacenters could save energy by delivering the same level of storage using fewer drives. Hitachi also claims to have increased the mean time before failure rating of the drive to two million hours, resulting in a failure rate around 40% lower than the industry average (1.2 million hours MTBF). Both Ultrastar 7K3000 models are available with regular and bulk data encryption (BDE) options. Although Hitachi made no mention of pricing, the SATA versions are already shipping, while the SAS models are expected around mid-year.

Toshiba launches world's first LIF SATA 1.8-Inch HDDs
TechSpot

Spoiler

tsitaat:

Toshiba has announced the industry's first 1.8" drives with low-insertion force (LIF) SATA connectors, enabling a 10 percent smaller footprint compared to standard 1.8" drives using microSATA connectors. Samples will be available for customer qualification next month. The new MKxx39GSL series was developed for use in multiple devices, including tablets, consumer electronics devices, and as external HDDs. They are designed for the most demanding mobile computing applications, surpassing 2.5" HDDs in terms of vibration robustness, low power consumption, and quiet operation. There are three models, pricing for which has not yet been announced: MK1639GSL (160GB), MK2039GSL (200GB), and MK2239GSL (220GB). The last one features the largest capacity 1.8" single-platter HDD (5mmH) available. All drives in the family feature a 16MB buffer for improved performance, and are capable of tolerating up to 1,500Gs of non-operational shock and 600Gs of operational shock, compared to 900G of non-operational shock and 400G of operational shock for the most robust 2.5-inch HDDs currently available. The drives are also exceptionally quiet, operating at 14dB at idle and 15dB at seek. They also require only 0.35 Watts of power at low power idle, the smallest power consumption levels for any SATA drive. All of this performance is delivered in a 5x54x71mm form factor, and weighing just 48g. "These new drives build on Toshiba’s history of innovation and leadership in the 1.8" drive segment," Maciek Brzeski, vice president of mobile marketing at Toshiba Storage Device Division, said in a statement. "Designers of next-generation consumer electronics, tablets, and mobile devices need disk drives that will stand up to the demands of day-to-day usage in a world increasingly defined by mobility and connectivity to all forms of content. These newest members of our 1.8" family are designed to meet those demands."

Millist 2,5" 500GB HDD soovitatakse? Võiks ikka 7500rpm olla. 60€ kanti.

[AJ]

7500rpm ketast vist ei ole, mõtlesid 7200rpm?

[kaspir]

AJ, njh, tõesti. Numpadil need arvud lähestikku. 7200 mõtlesin jah.

[AJ]

See peaks olema päris korralik.

Testisin 2,5" HDD kiiruse poolest: 5400RPM 500GB on kiirem kui 7200RPM 320GB ketas ja hind sama.
Seega võidab suuruses, voolutarbes ja vaikuses.

Mis mudeleid sa võrdlesid?

[RCC]

xpeega peaks olema ju ka see asi (ja nende karpidega), et klastri suurus tuleb teha suurem default on 512baiti aga sellise klastriga jäämegi lugema
alates klastri suurusest 4kb peaks ka suurem kui 2tb ketast vabalt kirjutada/lugeda saama. muidugi see 2tb piirang tuleb mbri piirangust, aga kui on gpt jne pole muret nagu laulusalmis

edit siis: tähendab, kui kasutada mbri siis on ühe ketta maksimaalne kasutatav maht ükskõik mida tehes ikka 2tb, ka siis kui see ketas teha dünaamiliseks. küll aga saab erinevaid 2tb seid (kuni 32 ametlikult) spännida üheks suuremaks volüümiks aga pisvinni all dünaamilistega mässata on enam kui üks suur jama. seega peab kasutama gpt kasutamise võimalust, siis hakkab mängima rolli ka klastri suurus, mida suurem klaster seda suurem maht. filmidele võiks nagunii kohe 64 kilose ära käristada

[SurfData]

lisaks oleneb kõik ka platterite suurusest. 1 platteriga 500gb on kõvasti kiirem kui 2 platteriga 500gb. näiteks WD 3TB, mis on 5400rpm on üsnagi võrdväärne väiksemate 1-2TB ja 7200rpm ketastega. Seega olenevad asjad/kiirused väga paljudest mõjutajatest.

Hetkel laiatarbe kasutuses olevate andmekandjate TB hindade võrdlus:

Optiline ketas: DVDR kõige odavam.

750GB on millegipärast teistest kallim.Muidu hea tabel

[smurfer]

[karuke]

Terkest,

otsin omale ketast HTPC jaoks, selle peale läheksid siis andmed ja ilmselt 2x et RAID teha (backupi jaoks) süsteemi jaoks on SSD juba välja valitud. 64Gb Crucial.

Kui ma aga HV otsingu ketaste alt lahti lõin, vaatas mulle otse selline 40 ketast umbes alates siis min 750 GB - 1,5TB. Hind võiks jääda sinna 50Euro piiri aga kui on hea ja vastupidav ketas siis võib ka rohkem tiba maksta. Aga mitte ei oska valida nende hulgast.

[martin366]

Samsung Spinpoint F3 103SJ 1TB peaks su nõuetele vastama, hea asi

[karuke]

Tänud ka väga kiire vastuse eest.

Samsungi nimi muidugi teeb kole kartlikuks, kuidas asjal lood vastupidavusega on? WD või Seagate pole parem?? JA kas selle RAID 1 puhul võin teise ketta hiljem järgi lükata või peab asi kohe toimuma?

[RCC]

wd pole kohe kindlasti parem, kui rääkida laiatarbe ketastest, kui rääkida raidi jaoks vajaminevast pole wd ja seagatel erilist vahet. aga võiks valida ka veel hitachi ultrastar seeriast, ja samsungi praak on ka tunduvalt väiksem võrrelduna näiteks wd-ga

[DVDRW]

WDga mul kah halvad kogemused. Scorpio Black ja Blue 2,5" läksid hiljuti

[Kirsa]

[karuke]

nagu eelpoolkõneleja mainis, et tasuks isegi hitachi ultrastar seeriat vaadata? Oskab keegi neid ka soovitada?

[kriimsilm]

[RCC]

näiteks mul oli wd green seeriast katkiste ketaste virn olemas (julgelt üle 10 ne) , terasd, vähemad/suuremad ja kõigil mingi äda.

[martin366]

Igal tootjal mõne kindla mudeliga probleeme, kõik ei saagi täiuslik olla ju

[Tomorrow]

Jah näiteks Seagate 7200.11 firmware jamad.Samsungi algsete F1 ketaste puudulik QA jne.Vot Hitachi kohta pole tõesti midagi kuulnud .Samas enda senised kogemused WD-ga positiivsed.

[SurfData]

[bladerunner]

SurfData, mõni 2TB Hitachi ikka ka "lennanud" on? st. võrdluseks peaksid ikka mudelite müüginumbrid enamvähem võrdsed olema.
Muidu endale meeldivad ka Hitachi kettad. Kuigi hetkel masinas WD GB, kuna H... lihtsalt ei pakkunud tol hetkel 2TB ketast.

Seagate ships over 1 million self-encrypting HDDs
TechSpot

Spoiler

tsitaat:

Seagate has announced that it has shipped more than 1 million self-encrypting laptop and enterprise hard drives. Seagate now ships 24 products in a family of self-encrypting drives (SEDs) that includes Savvio, Cheetah, Constellation ES, and Constellation. Seagate enterprise SED shipments have tripled over the past two quarters, while the company's laptop SED shipments have doubled in each of the past three years. Seagate has managed to reach the milestone thanks to support from original equipment manufacturers (OEMs) and independent software vendors (ISVs). Six OEMs (Dell, Fujitsu, Hitachi, IBM, LSI, and Network Appliance) currently offer products powered by Seagate enterprise SEDs. Seagate's ISV partnerships have grown to include security leaders Credant, McAfee, Mobile Armor, Secude, Softex, Symantec, Wave Systems, and WinMagic. They provide management software so that organizations can easily manage and protect encryption keys and passwords to simplify deployments of Seagate's Momentus and Momentus Thin SEDs. Seagate's family of Savvio, Cheetah, Constellation, and Momentus SEDs have secured FIPS 140-2 certification from the US National Institute of Standards and Technology (NIST). The company thus has the first laptop and enterprise HDDs with the government certification, which clears the way for deployments of Seagate SEDs by all US and Canadian federal agencies, many state and local governments, and multiple regulated industries. Several OEMs are now qualifying Momentus SEDs that are compliant with the Trusted Computing Group's Opal specification, issued by the international body in 2009, and which aims to increase the adoption of SEDs.

2TB ketta hind langes 60 senti. Seagate möödus hinnaga Samsungist
Kui hind alla 60€, siis läheb 10TB NAS ehitamiseks

[Tomorrow]

[kaabakas]

Puhver on ka rohkem konkreetse ketta mudelis kui sata3 taga kinni. Ja ega seal 64 või 32 ka sisulist vahet pole.

[kriimsilm]

Viimane kord kui uurisin, siis räägiti, et WD Black SATA3 liidesega on uuemate, suuremate platteritega (500GB). SATA2 liidesega variant võib olla ka vanemate, väiksematega.

[HA]

Soovitage head kiiret 2TB ketast...Hitachi väga ei tõmba, ise võtaks Seagate või WD

edit: praegu vaatan et Seagate 2TB Green (5900rpm) ketas on kiirem (Sustained Data Rate OD) kui XT seeria (7200rpm) oma...WTF?!
